Problems solved by technology

Usually, the method of moving objects multiple times by hardware and splicing multiple images by software is used. The former increases the volume of the working head, reduces the space utilization rate, and makes the control process lengthy. It is difficult to complete without motion monitoring and correction. High-precision placement of large-size components; image stitching cannot avoid the loss of accuracy caused by edge pixel errors. In addition, the image edge and center distortion calibration process is complicated

Abstract

The invention discloses a shooting method of elements, and the method comprises the following steps: S10, shooting a first image: shooting the whole element through a first shooting unit, and obtaining the first image; S20, according to information, different from other regions, of the key feature region of the element, extracting a region containing the information of the key feature region; S30, analyzing the center coordinate S0 of the first image, the center coordinate S1 of the first feature region A1 and the center coordinate S2 of the second feature region A2 according to the first image; S40, determining the movement amount D1 of the element; S50, determining the movement amount D2 of the element; S60, calculating the offset of the element; S70, correcting the position of the suction nozzle according to the offset of the element; the method has the beneficial effects that the element is identified, and the position of the element is accurately judged and corrected.

Description

technical field [0001] The present invention relates to the technical field of component installation, and more specifically, the present invention relates to a method for photographing components. Background technique [0002] The placement machine can only recognize objects in a limited size range, and it is difficult to meet high-precision placement for components larger than the predetermined size. Usually, the method of moving objects multiple times by hardware and splicing multiple images by software is used. The former increases the volume of the working head, reduces the space utilization rate, and makes the control process lengthy. It is difficult to complete without motion monitoring and correction. High-precision placement of large-size components; image stitching cannot avoid the loss of accuracy caused by edge pixel errors. In addition, the image edge and center distortion calibration process is complicated. Contents of the invention [0003] In order to over...
