一、引言目前,国内外很多研究学者对热处理炉、温(湿)环境试验设备自动测试技术进行了研究,提出一种使用热电偶或水冷式抽气热电偶对燃烧室或烟道中的高温烟气温度逐点测量来获取运行中实际温度场数据,但受感温元件高温性能的限制,只能作短时间的测量,并且受介质的影响测温元件高温条件下使用寿命缩短,测量准确度随之降低;还提出了一种温度场测量方法,该方法利用数字图像处理技术根据三基色 I. INTRODUCTION Nowadays, many researchers at home and abroad have studied the automatic testing technology of heat treatment furnace and temperature (wet) environmental testing equipment, and put forward a new method that uses thermocouple or water-cooled exhaust thermocouple to measure the high temperature smoke Temperature point-by-point measurement to obtain the actual temperature field data, but by the high temperature performance of the temperature sensor limits, only for a short time measurement, and the temperature of the media under the influence of high temperature conditions shortened life expectancy, measurement accuracy With a decrease; also proposed a temperature measurement method, which uses digital image processing technology based on the three primary colors
