Angle to objects

AngleToObjects calculates the horizontal bearing to each color-threshold detection and sorts results from largest area to smallest.

Inputs​

detections is a list of dictionaries. Each item must contain normalized bbox coordinates, class_id, and color_name. area is optional and defaults to 0.

Outputs​

angles contains angle_degrees, angle_radians, bbox, class_id, color_name, and area. Positive angles are right of image center.

When to use​

Use this when downstream code needs horizontal bearings from color-threshold detections.

Configuration​

  • camera_fov_degrees: Horizontal field of view. Default 60.0; range 10.0 to 180.0.

Limitations​

Bounding boxes must use normalized coordinates from 0 to 1. The operation does not account for lens distortion.
