Module test_utils 

Utilities for testing and synthetic data generation.

Structs

TestImageParams

Parameters for generating test images with photometric variations.

Functions

apply_brightness_contrast

Apply brightness and contrast to an image. brightness: -255 to +255 contrast: 0.0 to 127.0 (1.0 = no change)

compute_corner_error

Compute mean Euclidean distance between detected and ground truth corners. Handles 4 rotations to find the minimum error.

compute_rmse

Compute RMSE corner error between detected and ground truth corners.

count_black_pixels

Count black pixels in binary data.

generate_checkered

Generates a checkered pattern image for benchmarking.

generate_synthetic_test_image

Generate a synthetic image containing a single AprilTag or ArUco tag.

generate_test_image_with_params

Generate a test image based on the provided parameters. Includes tag generation, placement, and photometric adjustments.

measure_border_integrity

Check if the tag’s outer black border is correctly binarized. Returns the ratio of correctly black pixels in the 1-cell-wide border (0.0 to 1.0).
