Research on device and method of vision inspection of a vehicle dashboard framework

Computer vision inspection possess the advantages of high speed, high accuracy, excellent flexibility and so on, which has been applied extensively in lots of fields of industrial product inspection. The advanced inspection techniques and inspection methods of manufacturing enterprises for automobile have become an important factor which restrains the automation of automobile manufacturing and quality improvement of auto products. Based on the manufacturing quality problems of vehicle dashboard framework and the weaknesses existing in traditional manual inspection method, a scheme of vision inspection is proposed in this paper aiming at columnar dashboard framework, and a novel device for detection and location is designed. In the mean time great researches on critical technologies and methods of detection have been made. The analysis of experimental results indicates that the error of the vision inspection system developed in this paper is less than 0.1mm, which exhibits a higher precision relatively. And the inspecting time is below 1.5min per piece, which satisfies the requirements of production online inspection and improves the inspecting efficiency remarkably.
