A real-time moving automotive vehicle identification system (AVIS) has been developed for intelligent vehicle highway systems (IVHS). AVIS consists of 3 major elements: invisible bar-code material, optical scanner, and DSP board. The invisible bar-code material reflects only the specific wavelength light (1500 nm). The optical scanner developed can read the invisible bar-code data only at the corresponding wavelength light. The TI TMS320C31 digital signal processing (DSP) board has been implemented. The DSP board processes the bar-code data obtained from the optical scanner through the invisible bar-code. The DSP board operates at 33 MHz with the image processing algorithm which includes error-detecting and error-correcting capabilities. The system has been tested and the results show that the AVIS performed successfully. The AVIS is expected to be applied to the non-stop toll gate and violation enforcement system.
