Red Light Video System (RLVS)

The purpose of this project is to provide an alternative red light runner detecting technique. The existing detecting systems use buried loops hence require road works when installing the systems in urban transportation systems. The RLVS employs video processing technology to detect red light runner, and transfer the offenders’ pictures to police centers through a GSM channel. The following figure depicts the diagram of the RLVS. The aim of this circuit is to provide a high-speed channel to transfer the image data from the digital camera to the personal computer, and offer a control port to operate the digital camera and the video camera. When I designed the RLVS, the commercially available digital camera only supports slow serial data transmission which can’t meet the requirement that the digital camera may continuously take snap shorts. The RLVS uses ECP parallel port. Therefore, it is able to transfer the image data from the Compact Flash Card to the personal computer at more than 1M bytes per second.
