Abstract: At present, the effective range of the monitoring system for violation of traffic line is small, and the detection accuracy of violation is still to be improved. In order to expand the scope of monitoring and improve accuracy, this paper proposes a new method of vehicles for violation of traffic line based on high speed ball type camera. First of all, according to the actual demand, we design the hardware system and software system, and by highspeed ball machine mobility, a method is proposed based on static detection and dynamic capture, to expand the scope of supervision. In addition, aiming at the problem that the accuracy rate is not high, the two step rolling line detection algorithm is proposed, That is, according to the prospect of the smallest external rectangular box to determine the rolling line, and then further through the region near the rolling line statistical prospects to accurately judge, thereby improving the accuracy of the rolling line detection and antiinterference ability. Experimental results show that, compared with the traditional rolling line detection system, the system expands monitoring range 1 times, and the detection accuracy is improved by 21.1%, realizes the effective supervision of the vehicle in a large range.
