Embodiment Construction

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention belong to the protection scope of the present invention.

[0042] Such as figure 1 and 2 As shown, a visual recognition method according to an embodiment of the present invention includes the following steps:

[0043] When the machine vision recognizes the color of the marker points in the corresponding interval, it will binarize the image, select the image in the interval, and then label it, and the part corresponding to the marker point color in the visible range of the machine vision will form A set of coordinates, including the coordinates of t...

Abstract

The invention discloses a visual recognition method and a system thereof, and the method comprises the following steps: recognizing the colors of mark points in a corresponding region, and enabling machine vision to form a coordinate set at a part corresponding to the colors of the mark points in a visual range; after the coordinates of the mark point in the machine vision coordinate system are obtained, converting the coordinates of the center of the first mark point in machine vision into the coordinates in a mechanical arm system, obtaining the center coordinate of the second mark point again by employing a mode that a mechanical arm is combined with a lamplight projection method, and comparing the error between the center coordinate of the first mark point and the center coordinate ofthe second mark point; and obtaining a third mark point coordinate according to a comparison result, and comparing the third mark point coordinate with the coordinate set. The method has the advantages that the cost can be reduced, and high-precision recognition and positioning are achieved.

Description

technical field [0001] The present invention relates to the technical field of visual recognition, in particular to a visual recognition method and system. Background technique [0002] Binocular stereo vision is an important form of machine vision. It is based on the principle of parallax and uses imaging equipment to obtain two images of the measured object from different positions, and obtains the three-dimensional geometry of the object by calculating the position deviation between the corresponding points of the image. Information method, however, the accuracy of the visual recognition system is directly proportional to the price, the higher the recognition accuracy, the more expensive the price. Under certain conditions of the image acquisition system, the algorithm required to improve the accuracy of image recognition is relatively complex. Aiming at the problems in the related technologies, no effective solution has been proposed yet. Contents of the invention ...
