Abstract

The present invention discloses a robot visual recognition and positioning method for the features of a manhole cover and bolts of a tank truck, which specifically comprises the following steps: Step 1: Ensure that the tank truck is in a stationary state, the robot carries a visual device, and after the visual device is initialized, the laser sensor gives the rough position of the manhole cover, a wide-field camera images the manhole cover, and successively collects images of the manhole cover body; Step 2: After image processing, the target position is calculated and transmitted to the robot end, and the robot is guided. The field of view presented by the first large field of view is 1.2 times the diameter of the manhole cover, and a template matching algorithm is used to match the target position; the present invention realizes the accurate recognition of the shape and position of the manhole cover of the tank truck and the bolts around it under the conditions of complex outdoor light changes and large changes in the consistency of the outer dimensions of the operation target; the present invention realizes the unmanned operation process of the visually guided robot, with a high degree of automation, high efficiency, and improved operation safety.
