Visual robot underwater target identifying and tracking method and system

The invention discloses a visual robot underwater target identification and tracking method and system, and relates to the technical field of underwater target identification and tracking, and the method comprises the steps: adjusting light according to the gray average # imgabs0 # of an underwater image; target identification is carried out on the real-time underwater image, and the ultrasonic transmission speed C and the target distance S of the current position of the robot are obtained after calculation; the actual tracking speed # imgabs1 # of the robot is obtained through calculation, and the predicted tracking time Yt and the predicted tracking distance Ys are further obtained through calculation; and calculating to obtain the electric quantity # imgabs2 # required for completing tracking, judging the size relationship between the electric quantity # imgabs2 # and the real-time electric quantity # imgabs3 # of the robot, and sending out a corresponding tracking early warning.
