In order to remove or at least significantly reduce the interference caused by incident laser, the detection for the laser spot in infrared image is indispensable. According to the shape and gray distribution characteristics of laser spots, the laser spot is identified and located in the infrared image by using the SIFT feature matching algorithm. In order to verify the effectiveness of this method, interference laser irradiation experiments with different laser powers are carried out. The experimental results show that this method can accurately detect laser spots in infrared images, and can adapt to different sizes of laser spots.
