Analyze the advantages and disadvantages and applying condition of the existing object
detecting algorithm, aims to body's variation and real-time and dynamic, combing with Histogram of Gradient statistic method, classify organ of level-connect mechanism and leaning algorithm based on Adaboost of face-detecting Boosted Cascad algorithm, to realize the object detect in car aided driving system. References the sift algorithm rationale and algorithm tracing steability to match and trace the object by characteristic in local area, eliminate the unuse information, simple the search area and speed the tracing. By practical video testing, this method does well in passengers and cars real-time detecting and tracing.

Nowadays the Gate-Ban Controlling System mainly uses the MCU as the control center, but the MCU has some disadvantages such as lower reliability and less expandability. Aims at resolving these problems, analyzes the modules' construction and designs the hardware platform and software platform of the system, develops the video collection functions at the supervising terminal based on Linux system, uses ARM as the control center and gets the information from extended ports by ARM control panel, and then transports them in SMS by using GPRS platform, at last the wireless long-distance supervise and control can be achieved. In the experiment the results show that the method proposed in this paper has good reliability and expansibility.
