Based On Linear Ccd High-speed Object Speed And Position Measurement

In the projectile testing system, the performance parameters of the projectile is obtained by measuring the speed of the projectile and the target coordinate, so testing the speed and the coordinate plays an very important role in the pratical projectile testing system. Based on tracking domestic and foreign research results, research the key technologies of the CCD optical target deeply. A testing system was designed based on the intersected CCD optical target, which can get the speed and coordinate at the same time. The system adopts four CCDs which are divided into two optical target intersections, and tests the target by the two optical target intersections, which is placed through before and after the target, so the measurement of the speed and the coordinate information can be obtained at one time,and meanwhile the projectile trajectory between the two ballistic target surface is reproduced.The main work of this thesis:based on Study Linear array CCD, particularly the CCD trigger ways and drive timing control method, design the system solutions of the intersection CCD targets, and determine CCD intersection measurement of the best disposition method by calculating, derivating, and achieving the system through the simulation. Finally, use linear array CCD cameras commercialization to put up the measurement system, and write the applications using the camera's SDK in VC++to realize the camera control, the data acquisition, and finally show the results of measurements, and three-dimensional frame in which to recreate projectile's flight trajectory.
