2018-04-19 02:19:32 -0600 | marked best answer | Aruco Markers point position estimation I need to detect and track an area of fixed size (let's say 1mt by 1mt). I am using 4 sets of 3 markers (each one for a different corner) so that by reading the marker Id I can know which corner it belongs to. Each set of marker has an L disposition (oriented to match the corner shape). If I can detect all the markers I am able to successfully identify the target area. But, if one or more markers are not detected (e.g. they are outside the frame) I would like to use the others to estimate the missing points. Unfortuately pose estimation is good locally around the marker but gives very poor results if i try to estimate the position of farther points. The code I am using at the moment is something like this At this point I expect estimate to be the point I wanted expressed in screen pixels. But the result is often very bad. I also tried using PoseTrakcers and "homemade tracking" by saving the previous positions of the markers and then by trying to predict the next. Am I doing something wrong? Is there a better way? I am using OpenCV 3.4.1 and Aruco 3.0.6. Thanks in advance. |
