Laser Beam Measurement Based on Image Enhancement Algorithm
This paper puts forwards a novel algorithm for laser beam measurement based on the enhancement of infrared image, which has strong noise background and low contrast. First, laser beam image were divided by “three order invariant moments” with the idea of statistical probability, and objects that need to be measured were extracted; Then, four mathematical models were established on the basis of “γ-correcting” algorithm, and an improved“(a, b, γ)-correction” algorithm which is based on PSO algorithm has been proposed by solving the mathematical models respectively. The PSO algorithm will be used in the process of the enhancement of laser beam.
