High-Speed Trapezoid Image Sensor Design for Continuous Traffic Monitoring at Signalized Intersection Approaches.

摘要

The goal of this project is to monitor traffic flow continuously with an innovative camera system composed of a custom designed image sensor integrated circuit (IC) containing trapezoid pixel array and camera system that is capable of intelligent future extractions. The new trapezoid CMOS image sensor IC was designed, fabricated, and tested. New feature extraction algorithms for moving object monitoring was developed and implemented in field programmable gate array (FPGA) platform. A camera system composing of FPGA platform to run the algorithms and control the trapezoid imager was developed.
