- Parameters
image (numpy array) – The image you want to detect april tags in.
- Returns
list[
AprilTagDetection]
- class AprilTagDetection(top_right, top_left, bottom_right, bottom_left, tag_id)¶
Result object that pairs with
AprilTagDetector.- markup_image(image, tag_id=False)¶

- Parameters
image (numpy array) – The image you want to overlay the detection on.
tag_id (bool) – Set True if you want to also overlay the tag id of the detection.
- Returns

- Type
string
- property corners¶
Corners of the detection.
- Returns
namedtuple with the following fields:
