激光加工温度场的检测对实现激光加工智能化有重要的实用价值。根据比色测温原理，提出采用彩色CCD和计算机图像处理相结合检测激光加工温度场的实验方案，研究CCD比色测温的温度标定。采用BF1400和BBR1000型国家标准黑体炉作为温度标定仪器，用WV-CP474型CCD相机在标定温度范围700～1400 ℃时，每隔100 ℃拍摄黑体炉靶面图像。开发了基于VC++的温度场图像处理专用软件，并对CCD拍摄的图像进行处理，建立了温度与比色值的数学关系表达式，并给出了待定系数。结果表明：CCD测温数据与现行标准测温数据之间存在良好的对应关系，进一步发展后，可成为激光加工温度场检测的有效手段。

It was inportant in measuring temperature field in laser processing for laser intelligence process. The measurement of temperature field in laser processing by color CCD camera and computer image technology was presented in this paper, and which is focused on the calibration of CCD colorimetric method. BF1400 and BBR1000 standard blackbody furnace and WV-CP474 CCD were used in this method. The images of temperature of blackbody furnace had been taken in step of 100 ℃ from 700 ℃ to 1400 ℃. Special program based on VC++ had been developed to process the images, and the relationship between colorimetric level and temperature had been established. It was shown that a good agreement between testing dada and real data, and it will be a useful method for measurement of temperature field for laser process after developed.
