| Abstract: | With the rapid development of high-speed railway in China, the need for high-speed measurement technology of rail profile is becoming urgent. Based on triangulation photogrammetry and system on programmable chip （SOPC） technology, this paper utilizes sub-pixel algorithm and soft IPs of NIOS II processor and Ethernet interface to capture in real-time and process in parallel the images of rail profiles, resulting in highly accurate on-line measurements of multiple rail profiles. The design of high-precision and high-speed image processing system based on the collaboration of SOPC and PC are described in detail, and experimental verifications are also provided. |
