What a great bundle! Mavic 3 multispectral + PIX4Dfield :D
A worthy sucessor for the P4M, great job on the video!
Very helpful step by step tutorial. Definitely saving this one for future reference. Thank you!
Thank you very much for the thorough view of the integration between Pix4D and M3M. This combination is quite good for customers which would like to do “the things” in house and w/o having deep knowledge of NDVI, CWSI and other indices. Really helpful!!!
Looks like Pix4d got one of the first units, love it! Pix4dfields plus DJI drones are my favorite combination. Can't wait to test the magic tool with the increased rgb resolution of the M3M for weed detection in PIX4dfields.
Is it possible to automatically detect weeds with these two combinations? Or can it be diagnosed entirely by seeing?
@@AybarsAgriculture yes! you can detect weeds with RGb imagery + PIX4Dfields. ruclips.net/video/W-ycuKz1DF0/видео.html&ab_channel=Pix4DAgriculture
Thank you for making this tutorial sir, awesome and perfect explanation. 🤗
excelente explicacion abrazo desde argentina
Thanks for video
bbuddy- excellent ~ all the best.👌
draganfly is undoubtedly the best drone company!
It is providing support in ukraine by supplying ukrainian people with medicines, insulin and much more.
with this it is increasing its visibility and brand awareness.
has an experienced team and unique technology, currently very underestimated based on its potential!
100% agree $DPRO is the best!
Great explanation! In the case of spraying drones, in which format do you export the variable rate application maps? (For weeds control) And which dji agras do you use?
Using a calibration panel that was designed for a camera with different wavelengths is definitely going to affect the precision of reflectance values.
DJI Mavic3M wavelengths:
Green: 560 ± 16 nm;
Red: 650 ± 16 nm;
Red Edge: 730 ± 16 nm;
Near infrared: 860 ± 26 nm;
Micasense Altum, RedEdge 3 and RedEdge-MX (which I am assuming this older bigger panel is from):
Green: 560± 20 nm;
Red: 668 ± 10 nm;
Red Edge: 717±10 nm;
NIR: 840±40 nm;
That should be pointed out!
thanks for the video! Do you know how the RGB camera performs in terms of dynamic range and color science compared to the mavic 3 classic? And video features? it would be nice to have only one drone instead of two. Actually in the same flight I always need to do both video, photos, panos, and a photpgrammetry grid.
Great job thanks
I've been asking around about the status of drones in Ag here in Yuma. It seems like there was a lot of studies and testing here back around 2016, but I have not seen or heard anything recently. Now this video just came out, and I see you are in Yuma!
Hi! Here is our latest update➡️ruclips.net/video/NP7pQpORpEc/видео.html
Hi Nathan. i am very interested to know if you have any good information about comparing results or quality of data to the Micasense products. How do you feel about the loss of the blue camera?
Great work guys! What is a "good" flight height, in order to have proper RGB and Multispectral images for agri use? In other words what GSD number is considered adequate for mapping and creating indexes for agri use (NDVI etc)?
Thank you
Hey, if it's about general plant vigor and larger-scale anomalies. Depending on the camera, you can go as low as 5 to 10 cm GSD, which should be over 120m flight height if your jurisdiction allows that. If you want to spot weeds and diseases or machine errors like clogged seeding rows, you should aim for GSDs under 3cm. That would be around 60m to 80m with this drone's 20MP sensor.
@@julius_pix4d Thank you Julius!
@Nathan Stein Hi Nathan! First of all, thank you for your valuable tutorials. Actually, the video you told me, helped me a lot! Have a nice day!
Hi Nathan, I would like to know if I can use these M3M images in the pix4d mapper in the same sequence that I already work with the images obtained by the parrot sequoia camera?...that is, convert each image (mosaic) to reflectance values and export to use, for example, the M3M camera bands in arcgis.
@@nathanstein-p4d thanks
Please compare and what is the difference between Pix4D and DJI Terra
Great tutorial. Does the Mavic 3 support planning and executing of missions requiring multiple batteries?
Hello, yes, it supports multiple batteries!
Can this spot new weeds in a previously Chem followed field and be used to create a spot spraying map? Thanks, great video.
Hello, yes you can spot weeds, everything you can see on the drone image can be converted in a spot spraying map.
hello dji mavic 3 multispectral ndvi images how do you combine them with agras t40 drone can you tell me. or if there is an application video can you share it with me
Hi, how do you mark obstacles for the sprayer, or areas where you don't need to apply? Because in Ukraine, we often encounter that trees or power poles need to be added to the kml immediately.
Hello, obstacle marking will be possible in the next PIX4Dfields version!
A W E S O M E !
Could you tell us the total time it took to prepare/fly/process this 20 acre field? I'm trying to get an idea of how long it would take to do large fields and if it is realistic from a business perspective
Is calibration of the multi spectral cameras on this drone necessary if a farmer asked you to give him a multi spec image of his crops? In general would you need to calibrate for agricultural work?
@Nathan Stein where can one purchase reflectance targets?
The only ones I see are from micasense but they don't seem to sell outside purchasing their system??
We’re you able to fly that entire plot with one battery?
Can the m3m be used to take precise coordinates from eletric poles to be used in a gis map afterwards? Cant afford to buy the matrice 300 rtk so looking for a cheaper and reliable model.
Hi Filippos! Yes, you can create an RTK map and then use annotations to get the exact location.
Muy clara la presentación..
Podria indicarme cual es las especificaciones del pc? Gracias
Buenas! PIX4Dfields funciona en la mayoria de PCs del mercado, un minimo recomendable es i7 con 16GB de RAM y placa de video.
Will Pix4D fields do stand counts?
Hi, how the RTK corrections are being sent, dont you need a base to use with m3?
@Nathan Stein Hi, Great video! Very new to this, waiting for my M3M to arrive. How do you find if you have a RTK network nearby?
hi i have a mavic 3m too. What do I need to calibrate this? how can i get it? What program do I use to calibrate this?
Hello! It depends on the type of work you are doing. If you are only flying a crop once and you will not compare in time, you can just use the drone as it is. PIX4Dfields will apply the necessary correction and calibration with the information your drone already provides. A reflectance target is required to obtain reflectance factors and compare several flights in time of the same crop and even compare flights from different drones. Without such a target, only indices that are self-normalizing produce meaningful results, i.e. indices that don't depend on the absolute value. Examples of such indices are NDVI, NDRE, VARI, SIPI2, LCI, BNDVI, and GNDVI. Not self-normalizing are TGI and MCARI.
I'm researching the uses for this particular drone and software. Do you know if this set up can be used to create maps of plant species? In particular tree species?
I would love to know if you get an answer to this, I am really interested to do variety mapping too.
Hi, you could try to use the Magic Tool to identify different tree species if you have multispectral data. It all depends how different the spectral signature of the trees is. You can try it with a free trial version of PIX4Dfields first.
can be used this drone for standard aerophotogrammetry without multispectral?
Yes it can!
So this map/data can be then transferred to the agras for weed spot spraying?
Hello, yes, you can check our step-by-step guide here support.pix4d.com/hc/en-us/articles/360019956578-Spot-spraying-and-variable-rate-prescriptions-for-DJI-Agras-T-series-with-PIX4Dfields.
If it is possible please share images taken by Mavic 3m as test dataset
We will be posting them soon, make sure to check our site for up to date information
I was wondering is multispectral only has one use - to gauge and analyze vegetation? There is no other usage for mavic 3m multispectral cameras?
Hi, it also has an RGB camera which can be used for normal mapping, videos and surveying. Multispectral imagery can also be used to map weeds or distinguish different plant species!
Can the software provide plant counting? Thanks! Great vid btw!
Hello, currently we can't count individual plants. But you can count manually with our annotation tools, or use the processed results in 3rd party applications for counting.
@@pix4dagriculture Thanks for the answer! It would be great if you could add plant counting feature in the future
what was the size of the field and how long did it take to scan. Lastly how long did it take to process the map?
Hello, this field's size is around 12 hectares and the processing took just 2 minutes. The processing speed depends on the hardware of your computer, the field's size and whether you opt for fast or accurate processing.
Can the mavic 3 use the thermal for pictures w/ pix4d. Or only live feed?
Hi Travis, yes it can with a custom camera xml! You can find this info on our page here: support.pix4d.com/hc/en-us/articles/360035481811-Your-camera-is-not-supported-at-this-time-PIX4Dfields
What’s the price tag for the dji mavic 3m
I Like the drone technology,
are you providing training based on the image processing software? or is any means i can get free from you
thank you
Hello, thank you for your interest. You can find more info about PIX4Dfields training here training.pix4d.com/bundles/pix4dfields-essentials-online-course-and-certification-exam
Hi Nathan, I'm trying to find the link to compatible calibration panels. Would you mind sharing here? Thank you!
Hi Jim, you can find it here support.pix4d.com/hc/en-us/articles/360022919691-Radiometric-correction-PIX4Dfields
@@pix4dagriculture Thank you!
@@JimDula did you ever find compatible calibration panels?
@@columbusexotics8002 Yes! They posted the link on this thread :)
@@JimDula Can you provide the link to buy the panel again? It seems to have been deleted... thanks
Could you share capacity ?ha/hours.
how did you get to use your Mavic 3 for mapping is this an updated feature?
We will release an update for PIX4Dfields, so it will be supported when the drone hits the shelfs.
Hi,
is it possible to upload a field scan to fendt one?
Hello, yes this possible as long as ISOXML or shapefile are supported.
Hi Guy's, I have just purchased pix4d fields and a DJI mavic 3m and cannot seem to export the field to my XAG V40. I tried to get FMS but only comes up with log in not create an account. Not sure on what to do, Can you help.
Hello, you would need to create an account using the XAG ONE app first. In case of any further issues you can contact our team here www.pix4d.com/support/.
Hi! how do Pix4d Field use the calibration picture? How can we check it? Any tips for buying a calibration panel in Europe?
Hello, the panel type that you can use depends on the camera model you have. PIX4Dfields currently supports
the following reflectance panels: Parrot, Airinov Aircalib, Sentera and Micasense. PIX4Dfields detects reflectance panel images and warns the user that calibration images were found and that they will be used to process the dataset.
You can check our support page for more info: support.pix4d.com/hc/en-us/articles/360022919691-Radiometric-correction-PIX4Dfields#label7.
Hi, will the analysis and processing work without the calibration panel? Seems hard to get and absurd expensive
When are you updating the pix4d mapper app?
@Nathan Stein not fields, no. Does it work on crystal sky?
Are there any specific conditions regarding the time of the multispectral data collection?
Hello, you can find this info on our article: support.pix4d.com/hc/en-us/articles/5648296477981-How-to-capture-drone-images-for-optimal-results-in-PIX4Dfields
@@pix4dagriculture thankyou!
What town/state did y’all trial (test) the new DJI 3M?
@Nathan Stein Hi Nathan! I'm from Yuma. I was wondering what permits or permissions you needed to fly so close to the Marine Air Station? Also did you have to go through DJI geo zones to "unlock" your flight controller related to fly safe.
@@markromero3748 Hi Mark, in that area we were in we had a flight ceiling of 250’ I was also working with the pilot from YCEDA as well. We called traffic control just in case. No issues flying, but of course the remote warned me and made sure I was aware of the airspace requirements. Hopefully that answers your questions
I wonder if the RedEdge band is false like on the P4M. Ihave never been able to output a correct NDRE raster with this drone.
If you use a reflectance target, you will get absolutely correct values. This is automatically applied in PIX4Dfiels if such a panel is present in the dataset. Otherwise, the values will still be relatively correct. You can verify that with the Satellite data import in PIX4Dfields, by pulling a satellite image for the same date as the drone flight; it will look very similar to the UAV NDRE.
@@julius_pix4d Would you be able to provide a raster to confirm what you write? If Pix4D field succeeds where the others fail, I buy a license right away.
@@lv_forestry7948 Here are some example outputs from a P4M dataset. drive.google.com/drive/folders/1R54TqrFHUZMUmHo95Wh3GzpOgg8_D9xQ?usp=sharing
@@julius_pix4d I have received and studied the rasters. Thanks. Unfortunately your software does not do better than the others, the NDRE is totally wrong. Just look at the histogram on the document you sent me. The P4M RedEdge band definitely has a problem, I didn't ask the question by chance, I work with a Resonon hyperspectral camera. By comparing the two cameras, the data coming from the P4M are aberrant. What about M3M? do you have rasters to offer?
@@lv_forestry7948 It is important to compare apples with apples here. One is an entry-grade camera that comes without a reflectance panel, and the other is a high-end sensor. What I said still holds true, relative value distributions between the P4M and other sensors are the same. For absolute repeatability, it may the wrong tool.
What are you looking for?
I think we should make sure de-warping is ON.. right?
It's annoying.
Should you use dewarping?
Hi Bailey, it should be off.
Can it map normal pics/rgb on same mission?
yes!
Can I make a heighmap with ma spark also?
Hello, it is possible to create a high-resolution DSM with the Accurate Processing Option in PIX4Dfields. You can see an example here www.pix4d.com/blog/pix4dfields-accurate-processing/
is this program compatible with mavic 3 as well?
Hi Skye, yes!
Hi Folks,
Has anyone tested PIX4D Fields on the new Macbook Pro M2 Max chip?
Hi, we tested and it works.
Hello, Is It a profitable business to give this service? Can you help me with some questions? I want to start a business by buying this Mavic 3 drone for agriculture and selling a filed management service in my Area, we have tobacco crops
