Test Result

In the actual operation by crane operator, there will appear situation that operator cannot make timely judgment on distance between crane and adjacent obstacle and cause collision accident. For this problem, this paper establishes anti-collision system on distance measurement focuses on ARM 11, on the basis based on machine vision and image procession, it considers effect of corresponding point match and extraction deviation of single characteristics point on measurement result, adopts one kind of method of distance measurement by monocular vision based on single characteristic point. The test result indicates that this system can effectively measure distance with obstacle, it has accurate measurement, high reliability and it can meet real-time requirement.
