Research on Dynamic Measurement System for Bulk Material Based on Machine Vision

摘要

In order to improve measurement accuracy and reduce maintenance work of dynamic measurement system, research is proposed on non-contract measurement method based on machine vision. To choose real-time measurement system of mining car as test object, and use binocular vision to calculate 3 D coordinates of contour, and obtain the values of volume and weight with material through operation. Test platform and work flow is designed in detail. A calibration method combined the advantages of optical calibration with camera calibration itself is proposed. To simplify the extraction and matching of feature points through using structured light. Test results show that this method can effectively improve the accuracy of dynamic measurement system for bulk material.
