Study on Construction Machinery Speed Measurement Based on Road Surface Texture Image

Abstract:

The construction machinery moving speed is an essential variable to identify its attractive performance. To realize construction machinery real-time and adaptive control, it is necessary to measure the machinery actual speed. But the traditional measurement method is not precise enough and costly too much. To search a new method, the high-speed linear CCDcamera is used to collect the road surface gray image. A machinery vision model is set up for the random road surface texture. Using cross-correlation algorithm two frame continuous image pixels are figured out. The construction machinery moving speed can be counted out by analyzing the vision model projection relationship and the two frame continuous image time.The feasibleness and precision of this method are proved by experiments.
