Problems solved by technology

However, with the gradual improvement of the production accuracy of gold fingers, the size of gold fingers is getting smaller and denser, and the complexity of gold fingers will inevitably affect the effect of single positioning accuracy. They will interfere with each other, which will seriously affect the accurate positioning of the gold finger

Embodiment 1

[0064] Please refer to Figure 1 to Figure 3 , according to the first aspect of the present invention, Figure 1 to Figure 3 An embodiment of a positioning method for a golden finger, comprising the following steps:

[0065] S00. Collect images of gold fingers, set the length direction of the gold fingers as the vertical axis, and the arrangement direction of the gold fingers as the horizontal axis;

[0066] Perform the following processing on the collected golden finger image;

[0067] S10. Delineate a small area: in the collected golden finger image, compare and analyze results of all non-local areas that have been obtained, and determine and delineate a small area with a predetermined size and a predetermined position. Wherein, the predetermined size may be: the width of the small area is in the direction of the horizontal axis, and the width covers at least 3 PINs, usually 3, 4 or 5 PINs. The length of the small area is generally smaller than its width. Since the small ...

Abstract

The invention discloses a gold finger positioning method and device and a computer readable storage medium. The method comprises the steps that a gold finger image is collected, and the collected gold finger image is subjected to small region delimitation, binarization processing, positioning calculation and comparative analysis, wherein during small region delimitation, a small region with a predetermined size and a predetermined position is judged and delimited according to an obtained contrastive analysis result of all regions except the small region in the gold finger image; during binarization processing, the small region is subjected to binary segmentation to obtain a gold finger binary image of the small region; during positioning calculation, the gold finger binary image of the small region is subjected to positioning calculation to obtain gold finger position data of the small region; during comparative analysis, the gold finger position data of the small region is compared with gold finger predetermined data and obtained gold finger position data of the regions except the small region to obtain a matching result or a non-matching result; and the steps are circulated till all acquired gold finger position data is sufficient for positioning a gold finger, and then positioning is completed. Through the gold finger positioning method and device, the gold finger can be positioned efficiently and accurately, and abnormal data can be eliminated.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a gold finger positioning method, device and computer-readable storage medium applied to gold finger image acquisition and positioning. Background technique [0002] Before testing the flexible printed circuit board (FPC), it is necessary to position the golden finger of the FPC so as to accurately connect with the external circuit electrically. The traditional gold finger positioning method is a general image acquisition method. First, a series of preprocessing such as filtering, denoising, and smoothing are performed on the collected large-area gold finger pictures, and a round of precise pre-positioning of the pictures is also included. , to get an accurate golden finger area. After the preprocessing, in the area of ​​the cheating finger, the positioning of the cheating finger is completed through an image algorithm calculation. [0003] Although this method is sim...
