The invention relates to the technical field of visual guide methods, and discloses a visual guide method for object grabbing of a robot hand. The visual guide method comprises the following steps: 1)performing position calibration on a visual camera positioned on a conveyor line, wherein the visual camera takes a picture of an object conveyed on the conveyor line, processes the picture of the object, and measures coordinate positions of the picture of the taken object; 2) converting the coordinate positions of the picture into coordinate positions of the robot hand, and obtaining an absoluteposition of the object conveyed by the conveyor line; and 3) correcting the absolute position of the object, and stopping the robot hand on the absolute position of the object. According to the visual guide method for object grabbing of the robot hand provided by the invention, the picture of the object on the conveyor line is taken by the visual camera, and the picture is converted into coordinate positions, namely the absolute position of the object, of the robot hand through measuring and calculating, so that the effect of visually guiding the robot hand to move is realized, and therefore,the robot hand can efficiently and accurately grab the object in an object grabbing process of the robot hand.
Description
technical field [0001] The patent of the present invention relates to the technical field of visual guidance methods, in particular, to the visual guidance method for robotic hands to grab objects. Background technique [0002] With the development of e-commerce, the express delivery industry, which is closely related to online shopping, has developed rapidly and has a broad prospect. However, in the express delivery industry, the phenomenon of "explosion" and "violent sorting" are often seen in the newspapers. The increase in business volume has brought a lot of work intensity to the express delivery industry staff, which seriously affects the further development of the express delivery industry. . [0003] At present, the introduction of automated equipment into the express sorting process has changed the backwardness of the existing manual sorting and has extremely high social and economic value. The survey found that traditional automatic sorting equipment often occupi...
