Super cool to see April tag detection running on a microcontroller. Can the OpenMV cam do Z, pitch, and yaw estimation of the tags as well or is it limited to X, Y, and roll?
Hi there! I'm using AprilTags for FIRST Tech Challenge and have a quick question. Is Readout Control the name of the algorithm used that handles the control flow for the searching/tracking AprilTag mode? Was not able to find much on the internet.Thanks!
There’s an example in the IDE. Readout control just changes the frame readout registers which allow you to scan around inside of the cameras image plane and not readout the entire image. It generally increases FPS and allows you a much larger field of view.
hi Please i need your help about the OpenMV distance between and Object to Camera, how can i programm it ? distance in OpenCV are not similar way to do it with OpenMV please can you help me about this . My project have to be done this week please .(method to programm how: to calculate distance between the Apriltag to Camera "OpenMV camera")thks in advance
Fantastic! Great use of the hardware!
guys you are awesome. keep it going, this is so useful. thank you

Yeah, you can do that too. You just need to know the tag size. Once you know that and the optical parameters it gives you everything you need.

This is awsome, have you published the code somewhere? i really could use this for a focus-project i'm working on
It's released with OpenMV already. See examples -> Readout control.
great!
Thank u for the awesome video. Is it possible to detect the distance to the tag accurately?
Somewhat. Tag distance is a 1/x type of thing. So distance is more accurate the closer you are. Farther away it gets less accurate.
It's a great job. I have a question, what's the distance limit of this algorithm?
Depends on the res. For 160x120 it's about 10ft with a 8"x8" tag.
Is there any reference about this method or algorithm?
this can do in opencv

You just need to read the z_translation() attribute and then multiply it by a constant (that you must determine) which gives you the distance.
how can i get z
