Paper Title:
Research on Designing on-Line Testing System of Automobile Engine Box
  Abstract

According to the current situation that most kind of automobile engine box were taken off-line random testing and the key technology of on-line detection, after the analysis of precision index and geometrical tolerances, the on-line testing model has been made by us. According to the model: ① double array CCD have been used to calibrate the positioning pin holes; ② image processing measurement method based on linear CCD has been determined; ③ automatic control method in which grating control scanning step distance has been adopted to improve the accuracy of image collection; ④ image edge extraction algorithm has been used to realize automatic fast testing. Experimental results show that: effective and rapid precise measurement can be achieved.
