This paper introduces a method of the colorimetric temperature measurement based on data fusion algorithm. The temperature results can be calculated by two adjacent color components through Bayer filter array in front of CCD image sensor of digital camera substituting into colorimetric formula. Each 4 × 4 pixels calculated can get eight temperature values. Because of temperature's continuity, one...
A measuring method of molten pool temperature which is influenced by various factors is designed based on multi-sensor data fusion. With the time-varying measured object, an adaptive weighted fusion algorithm for searching the minimum standard deviation is proposed here. The corresponding weight is achieved by using sensors measurements through approach of self-adaption. The statistic characteristics...
