Title:
ELECTRONIC ELEMENT POSITIONING METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2017/092427
Kind Code:
A1
Abstract:
An electronic element positioning method and apparatus, which can quickly and accurately position a pre-determined electronic element on a circuit board image to be detected. The method comprises the following steps: intercepting a sub-image on a circuit board image to be detected based on a detection window of a pre-set size (S101); detecting the sub-image according to a built detection model of a pre-determined electric element, wherein the detection model of the pre-determined electric element is obtained by training positive sample pictures and negative sample pictures, the positive sample pictures are pictures which contain the pre-determined electric element, and the negative sample pictures are pictures which do not contain the pre-determined electric element (S102); and when it is determined that the sub-image is an image of the pre-determined electric element, marking the sub-image as a target sub-image, and recording position information about the target sub-image on the circuit board image to be detected (S103).
