| Abstract: | Against the backdrop of ETC,the image collection module of the lane controller was designed and used for collecting the images of the vehicles.In respect of hardware in the system,the S3C2440A chip was utilized to be the center of the core board,and the CCD interface circuit was introduced in detail.For the software part of the system,the real time embedded Linux operating system was adopted,under which the image interface driver was programmed.The testing results indicated that the designed image collection module could accomplish its pre-determined requirements. |
