Combining CCD technology with image processing analysis, virtual instrument based high-temperature jet measurement technology is proposed. Image acquisition as well as real-time display of the jet is achieved by general image acquisition card under the LabVIEW platform. Then, the relationship between the grayscale and temperature field is established. A powerful image processing system IMAQ Vision is applied to obtain the distribution image of jet temperature field. Experimental results show that the proposed temperature measurement method is low-cost, high accuracy and simple operation, and it has broad application prospects, such as the thermal power plants, metal welding, smelting and other occasions.
