Research Of Image-Automata's Motion Parameters Test System

Testing for automata's motion parameters is a very important work for design and produce of automatic weapons.In the background of many disadvantages for the existed test systems home and abroad at present,with the researh of high-speed motion camera,this subject designed a new image-automata's motion parameters test system.Based on deep development of the test system,this paper make detailed discussion of the system from the sides of image calibration technology,controlling of MC1362 high-speed motion camera and image acquisition card ,design of the test system software,etc.This paper makes discussion of the test system's principle and system structure. Then begin with the discussing of the function of the image calibration system in the test system,two kind of image calibration system which based on vernier caliper and grating ruler are proposed. The principles,the design details and error characteristics of the two calibration systems are detailed described in this paper,also,the intercomparison of the performance of the two calibration system is made.Latter,this paper makes detailed discussing of controlling of MC1362 high-speed motion camera from the way of control principle, realizing way of virtual serial port,kinds of commands and realization of programming,etc.Meanwhile,from the discussion of the ActiveX interface and the dll interface provided by Sapera LT, its establishing way under Labwindows/CVI and VC++,and the realizing of image acquisition programming,detailed discussion of controlling of the frame grabber is made. On the side of the test system's software, this paper has designed the software with the centre of software interface,interface and operation process.The paper finished to control the MC1362 high-speed motion camera and the image acquisition card, solved the interface problems between Labwindows/CVI and MATLAB,Labwindows/CVI and VC++,discussion of problems of image display and dada process is made too.The designed software achieved to acquire,save the images and data processing,besides, analysis tools for the tested automata's motion parameters are also provided.Finally,through automata's motion parameters'live ammunition test experiment, examination for the image-automata's motion parameters test system and the two image calibration systems were made,the performance of the test system's software is also assessed. The experiment result shows that the relatively error of the two image calibration systems is less than 1%, the error of the automata's motion parameters test system is less than 1% too,the test software is easy to handle, and has stable performance, the preset goal has achieved.
