We have found that wind plays such a big role. I can tell you what we do though. If winds are less than 25km/hr, then we will fly at 3 meter , about 250 micron and will expect 10 meter swath. We will drop alt a little bit at a time to find a sweet spot in higher winds and lose a bit of swath. I have also come to love to film with a chase drone to get a real accurate look at how the fluid is behaving and adjust. For example if you have a look at the sequence starting at 10:17, you can see very well what a speed of 25 km/hr which is just below 16 mph, 3 meters alt and 250 micron behave like in a 15 km/hr wind. The wind direction also worked out so that we were able to fly the field with and then against the wind direction which also is a huge contributing factor. We do not love flying with a side wind.

I sure hope not. I love seeing the bridge when I drive by. I will be passing it next week.

This inspection strategy is a matter of maintenance. The purpose is to spot developing problems.

​@@libitronaerialdroneservice In this video the speaker speaks about much advantages by inspections and searching of grid problems, by using of such methods, like drone with visual and thermal camera. But video doesnt show this advantages, how this looks like. We see only new grid in good shape, without some problems, without demonstration of advantages and so on. I expected to see, for example damaged insulator, where in visual camera is nothing to detect, but in thermal camera this insulator is shining like lamp from warmth. To see bad distributed power on lines, which have different temperatures, too small dimensioned or damaged transformer, which is very hot, and so on.

4:54 has a damaged field side terminator, probably no thermal signature yet but an experienced eye could report it, create a work order, or being so new have the contractor who built it make warranty repairs before its a real problem.@@konstantinhuwa3064

Preventative.

These inspections can catch what roll-by line patrols can't: loose tiewires, broken strands on linewire, broken insulators, failing equipment, or loose hardware. Even vegetation requiring trimming.

Glad you enjoyed

Yeah you do. Montreal has one of the worst stadiums

...and in Calgary.

Thanks.

Our work Horse for this type of inspection is the M210 RTK with an X5S and 45mm lens and a Zenmuse XTR Thermal. We also use a Z30 very commonly, but since our usual procedure is to have simultaneous RGB and Thermal, the X5S is usually mounted. Some people will argue that the XT2 may be a better camera. It would offer some benefit but over all we like the XTR mainly because it is the best mapping Thermal camera we have used to date. We map a lot of commercial buildings. The sensor in the XTR is fantastic. And we also use the same RGB and thermal video for the roof inspection process. It works even more effectively with the roof inspections. Having said all of that, if our inspection type was a little different or if we were mapping the lines, then we would almost certainly be using an M300 with A LiDar set up. Mapping lines with RGB is very difficult to get the lines to produce well in the models. RGB is fine for an ortho, but not for a model in our experience. Maybe someone else is able to pull it off, but we have not in a satisfactory way. The M30 is also an excellent choice and something we are considering to try out.

Well there was no mapping or orthomosaics but rather just video and photographs, both RGB and Thermal. Flir studio for thermal analysis and premiere pro for putting a video together is all.

Ideal drone ..... seems like an easy question but it is not really. If I understand you well enough, you are looking for a thermal solution for inspections including facade. For most of the inspections you will be fine with a relative measurement because you will either be trying to identify insulation issues or water issues. The insulation issues are a bit tricky without a radiometric camera however even though relative temps show you where there is a change in temp. I find myself using the radiometric thermal for those inspections because the thermal output display just appears to be a dramatic difference when in most cases that is not correct. So I would say at minimum you have to have a thermal setup that can provide at least a temperature legend so you can identify what each display colour represents. So I think a good drone for you is one that can provide at the very least that information. It is very easy to just name a drone but I think you should do your homework and decide what model suits you. I am just offering my opinion on minimum specs. The truth is that adding a Vue model to a drone is a great option even though it will likely end up in a fixed position. I see those coming up for sale all the time in the Flir Facebook groups. The thermal decision may be more important that the RGB since most drones will work for the inspection. What you do have to do is make sure that the drone is compatible with the mission planning software that you choose. I think drone harmony is a very good platform for facade inspections but this is another thing that is very fluid and changes so fast. The is all a very long answer to finally say that you have to do your homework. I hope my intention is clear in my answer and I wish you all the best.

It really is nice.

We like the DJI M210 and M300 for inspections. We like the payload options and find them to be incredibly stable and reliable. They are also much easier to keep an eye on to comply with VLOS regulations than smaller drones. The inspection in this video was performed with an M210 V2. Thanks for watching and the question.

I've used the DJI Mini 2 for tower shots, cheap and low risk. Excellent quality 4K 30fps video if you don't need mechanical zoom 👍

Is this a proprietary software for the autonomous mission plan?

@@mbs7567 Workflow evolves with drone development. At the time this video was made, we flew manual missions and recorded the mission. Then it was repeatable. Since this time, we are starting to use the Autel Max 4T drone. We are developing a workflow for that drone.
