Problems solved by technology
[0003] However, at present, some processing plants still use the traditional manual positioning method or mechanical positioning. This method has the following disadvantages: (1) Positioning a single product for a long time, the detection workers are prone to eye fatigue, and are easily affected by emotions, and the positioning results are difficult. Guarantee; (2) Mechanical positioning requires high mechanical precision and complicated operation

Embodiment Construction
[0051] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the embodiments and accompanying drawings, and the contents mentioned in the embodiments are not intended to limit the present invention. The present invention will be described in detail below in conjunction with the accompanying drawings.
[0052] A visual positioning compensation method provided by the present invention includes a rotating platform 1 and at least two cameras 2, wherein the number of the cameras 2 is five, corresponding to the installation position above the rotating platform 1 such as figure 1 As shown, each point on the rotating platform 1 corresponds to the corresponding coordinates of the XY axis, and the present invention also includes the following steps:
[0053] Step 1: Camera 2 scans the product on rotating platform 1 and extracts the contour line;
[0054] Step 2: Calculate the translation and rotat...

The invention relates to the technical field of automatic positioning, in particular to a visual positioning compensation method. It includes a rotating platform and at least two cameras, and also includes the following steps: Step 1: The camera scans the product on the rotating platform and extracts the contour line of the product; Step 2: Calculates the translation ratio and rotation ratio between each camera and the rotating platform; Step 3: The product outline extracted by each camera is converted into translation XY and rotation angle Angle according to the translation ratio and rotation ratio; Step 4: Perform overall compensation and station compensation according to the translation XY and rotation angle Angle. The invention can quickly calculate the actual difference between the actual product position and the theoretical position, and compensate through the calculated difference, so as to achieve the purpose of positioning compensation.
Description
technical field [0001] The invention relates to the technical field of automatic positioning, in particular to a visual positioning compensation method. Background technique [0002] At present, there are many kinds of industrial products, and automatic positioning may be involved in the production process of industrial products. For example, printing and bonding are required in the automated production line, and each part can be installed in place quickly and accurately. [0003] However, at present, some processing plants still use the traditional manual positioning method or mechanical positioning. This method has the following disadvantages: (1) Positioning a single product for a long time, the detection workers are prone to eye fatigue, and are easily affected by emotions, and the positioning results are difficult. Guarantee; (2) Mechanical positioning requires high mechanical precision and complicated operation. [0004] With the development of science and technology...
