The Research Of Detection System To The Dynamic Object Based On Machine Vision Technology

The machine vision is researched mainly about the simulation of person's visual function with the computer, which founds and restores the real world model with the image, finally uses in detection, measure and control. The detection system based on machine vision technology, which includes CCD, optics imaging system, data gathering and procession system with computer, have the characteristics of the high precision to detect, the rapid speed, the convenience for application and so on. The artificiality with eyes cannot to analogy to this way.The drop point of the lubrication grease is the temperature when it is reached the certain fluidity in stated test condition. This temperature gives an index to the lubricating grease quality. In view of the shortcoming of original method, which detect by artificiality with eyes , the topic has designed a new detection system to the dynamic object based on machine vision technology, and can apply it to the drop point of the lubrication grease detection and the other fields that detect dynamic objects.The text introduces the automatic equipment for detecting the drop point of the lubrication grease based on machine vision technology, including two main parts: Temperature detection system and image detection system. Temperature detection system is to detect the temperature of the grease in a test tube and the oil heating up it, and the data gathering and procession system with SCM to the CCD signal will be go on ,then the temperature detected will be displayed on liquid-crystal display.In image detection system, the detection to the process and speed of the grease dripping with the CCD is described. Then the image signal will be transmitted to the SCM to do the difference operation and threshold processing, which to examine whether the dynamic object (oil) appears. The system will emit a signal when the first oil drip the temperature displayed on liquid-crystal display will be stop, and that one is the drop point of the lubrication grease the topic want.As the jumped-up detection technology, the machine vision is provided by modern industry the huge demand space. The method based on machine vision to detect the drop point of the lubrication grease has the following merits: automatization, high detection precision, the fine repeatability and reappearance. And it can be applied on the other fields that detect dynamic objects.
