AI Technical Summary
Traditional angle measuring devices for mechanical parts suffer from insufficient image acquisition stability, low calibration accuracy, and drifting measurement results due to uneven light sources and vibration interference in workshop environments.
The system employs a combination of a CCD or industrial camera with a telecentric lens, a uniform light source, and a high-precision calibration plate, along with a shock-absorbing bracket and an optical shielding device. It utilizes a trained deep learning model to detect calibration reference points, performs multi-image calibration, and adaptively updates calibration parameters based on environmental information to achieve sub-pixel-level feature point localization and multi-point fitting.
In a workshop environment, high-precision, stable, and consistent measurement of part angles was achieved, improving image acquisition stability and calibration accuracy, and reducing measurement result drift.
