The invention provides an underwater target recognition method based on sonar image and laser image information fusion. The underwater target recognition method comprises the following steps: acquiring a suspected target sonar image by using a two-dimensional imaging sonar; edge detection is carried out on the suspected target sonar image, and contour search is carried out on the sonar image after edge detection to determine a target position; inputting the target position information into a sonar angle calculation formula and a sonar distance conversion formula for calculation to obtain target angle information and target distance information; controlling the laser camera to rotate according to the target angle information to enable the laser camera to face the target; and the laser camera performs range gating imaging according to the target distance information to obtain a target laser image, and performs target recognition on the target laser image by using a target recognition algorithm to obtain target information. According to the scheme, manual intervention in the detection process is reduced, the defects that sonar image quality is poor and laser camera parameter setting is tedious are overcome, and underwater target recognition efficiency and accuracy are improved.
