Design and Implementation of Image Acquisition and Processing for TFDS

Abstract:

Some problems existed in IEEE 1394a camera of the Trouble of Moving Freight Car Detection System (TFDS), such as easy disconnection with electromagnetic interference, limited image resolution and low frame rate. To improve that, a GigE camera is used as a replacement. Images of GigE camera are acquired and processed using embedded system based on FPGA and DSP. First gray images are acquired and compressed by JPEG. Then compressed data is saved on hard disk and uploaded to the server in detecting center simultaneously. System construction is greatly simplified ,meanwhile the costs, volume and power consumption are also decreased. The system has worked with a stable status for a long period in the actual railway. The final tests demonstrate that the design is feasible of great application potential.
