Why Do Recognition Errors Occur?

Possible Causes

1. Images collected in the base library are not clear.
2. Qualities of the images captured by PUs are poor.

Common image quality problems: backlight, casting shadows, incorrect angles, and blurs.

Solution

1. Enter the images with good qualities into the base library to replace the poor ones.
2. Improve the PUs' snapshot conditions. For example, adjust the illumination to avoid backlight. Remove the blurred images and adjust the camera parameters to improve clarity.
