The results of experiment show that  motive vehicle detection by adopting digital image is one of key technologies. To detect motive vehicle accurately  the arithmetic proposed in the paper can suppress shadow availably  we establish an adaptive background updating model firstly. Noise is suppressed by using modality filter  detect motive vehicle accurately and satisfy real-time motive vehicle tracking. 2009 SPIE.  and we obtain binary image by using maximum entropy to choose dynamic adaptive threshold. Based on positive information of shadow and aspect feature of motive vehicle  we adopt HSV colour space and double threshold to solve the problem of vehicle shadow. According to prediction result of Kalman filtering   Design and implementation of high-speed digital CMOS camera driving control timing and data interface (EI CONFERENCE) 会议论文  OAI收割 Sixth International Symposium on Instrumentation and Control Technology: Sensors, Automatic Measurement, Control and Computer Simulation, October 13, 2006 - October 15, 2006, Beijing, China 作者:  Wang Y.;  Wang Y.;  Wang Y.;  Sun H.;  Sun H. 收藏  |  浏览/下载：41/0  |  提交时间：2013/03/25 High-speed digital cameras are progressing rapidly with the development of CMOS image sensor in these few years. In order to develop a high-speed CMOS industrial digital camera  the CMOS image sensor MI-MV13 is used. The sensor drive pulse and control timing based on Xilinx Virtex-II Pro FPGA is designed. A novel format of digital image transporting based on Camera Link data port is defined in this paper. It is implemented 1280 (H) 1024 (V) SXGA resolution digital image transported at a high frame rate of 300 fps (frames-per-second) with 5 Pixels 10 bit compatible Camera Link Medium Configuration. In addition  these functions that adjustments of exposure beginning time  integral time  AOI (Area of Interest) output and so on  are realized in a FPGA chip. All of the function modules are embedded in a SOPC (System on a Programmable Chip)  and further functions can be easily added to the chip at the second time development. Experimental results show that the design of driving control timing and data interface in FPGA is suitable for high-frame rate  low power  intelligent and miniaturization digital video camera.
