Abstract

Using thermal infrared imaging to obtain the temperature distribution of the train wheel sets is a new and promising temperature measurement method. The accuracy and precision of the method are suffered from vignetting. In this paper, the vignetting coefficient function has been derived and imaging system calibration is introduced to compensate the measurement result error caused by the inconsistent of the optic center and the image center. The vignetting correction is implemented on the hardware platform based on FPGA. Experimental results demonstrate that vignetting correction enhance the accuracy of measurement system.
