Research and Development of Vision Measurement System with Marked Targets

Abstract:

Aiming at the problem of 3D measurement to product in industrial, a vision measurement system with marked targets is researched and developed. The system is a 3D visual system based on a basic principle of close-range photogrammetry. After shooting objects with mark targets by a digital camera, the digital image processing and vision measurement processing are used to detect and match the marked targets in order to locate the geometry precisely. The system achieved the main function of image preprocessing, target center location, feature matching, camera calibration, 3D reconstruction and precision evaluation. Proved by the experiment, the system can reduce the dependence on hardware equipment, measurement environment and professional technology, and obtain stable and precise 3D reconstruction results, which can be applied to the calculation of monitoring point.
