Research On And Application Of Multi-sensors Fusion Intelligence Inspector

Vision is one of the most perfect sensation systems of human, and the machine vision, which can simulate human's vision, is also one of the most active branches in the domain of artificial intelligence. The multi-sensor fusion intelligent inspector based on machine vision technology is the intelligent inspection equipment integrated of optical, mechanical and electronic functions. At present, the research and application of machine vision technology is still in its initial stage in China; compared with the developed country it also has much disparity. Studying the intelligent inspector based on multi-sensor fusion not only conforms to the market demand of this kind of large-type intelligence inspector, but also is advantageous to the promotion of the research and application of the machine vision technology.Based on the studies of the related data from at home and abroad, this article presents the system design plan for the intelligent inspector based on multi-sensor fusion, and in detail introduces the structures and the function of each part. Multi-layer control system is used in the electric control system of the intelligent inspector based on multi-sensor fusion. The host computer is responsible for higher layer management and communication, while PLC is responsible for lower layer control. In order to separate goods from the high-speed production line steadily, one kind of new ejector is developed. The ejector adopts the method that hits goods with a ladder-type stroke. Thus, the ejected object is not easy to turn over even if it is on the high- speed movement.This article emphasizes on elaborating the design of the machine vision system in the intelligent inspector based on multi-sensor fusion. Specifically, it discusses the selection principle of the camera and the image capture card, and determines the use of intelligence inspector's cameras and image capture card. Since the light source and the illumination plan is of a vital significance to the machine vision system, this article designs the system illumination plan according to the actual demands, thus ensuring the image quality gained by the machine vision system. This text has also discussed how to carry on the software development of the machine vision system.The intelligent inspector based on multi-sensor fusion has the examination functions for bottle body, the bottle mouth, the bottle bottom and fluid position. To achieve these functions, with the consideration of the actual inspection features, this article puts forward to a set of practical examination algorithms on the basis of analyzing inspected targets. The operation indicates that, by using these examination algorithms in the intelligent inspector based on multi-sensor fusion, the examination speed can reach 10 bottles/second, and the average examination accurate rate surpasses 95%.According to studies in this article, the experimental equipment has already been developed. The theory and the algorithms stated in this article have been put into use on the massive experiments on the inspector. The results of the experiments have proven the validity of the design and the findings. So, it has laid a good foundation for further research and development in the future.
