problem with find marker #129

Closed sars-ivan-by closed 3 years ago

sars-ivan-by commented 3 years ago

I get error :WRN: Matrix is singular. Error, more than one new minimum found. pic10

this is my code `detector=apriltags3.Detector(quad_decimate=1,decode_sharpening=1) images,coordinats=division_of_img(img_cv) for img in images: imgs,c=division_of_img(img) i+=1 j=0 for imm in imgs: j+=1 detections = detector.detect(imm, estimate_tag_pose=True,camera_params=[fx,fy,cx,cy],tag_size=60)

detections2 = detector2.detect(imm,estimate_tag_pose=True,camera_params=[fx,fy,cx,cy],tag_size=90)

` I divided imagine for find without error "too many borders" because I don't want use any quad_contours

Closing since this is about the duckietown python wrapper. In particular I think that that repo is probably using an outdated version of apriltag3
