Abstract

The invention is suitable for the image detection technology field and discloses a deviation detection method and system, and terminal equipment. The method comprises the following steps of acquiringan ITO image and a golden finger image shot at a same position in a product; acquiring a first deviation detection area in the ITO image, and based on the first deviation detection area in the ITO image, acquiring a second deviation detection area in the golden finger image, wherein the position coordinate of the first deviation detection area in the ITO image is the same with the position coordinate of the second deviation detection area in the golden finger image; and based on a golden finger overflow width and a deviation threshold in the second deviation detection area, determining whethera golden finger in the second deviation detection area has deviation. In the invention, the deviation detection area in the golden finger image can be accurately determined, the accuracy of deviationdetection can be increased, whether the golden finger has the deviation can be qualitatively analyzed, and the concrete value of the golden finger deviation can be quantitatively acquired, which means the golden finger overflow width.

Description

technical field [0001] The invention belongs to the technical field of image detection, and in particular relates to a deviation detection method, system and terminal equipment. Background technique [0002] With the continuous development of high-end electronic manufacturing technology and the continuous improvement of user needs, people put forward new requirements for the reliability of electronic products. For example, after FPC (Flexible Printed Circuit, flexible circuit board) is pasted on flat glass, there will be a certain deviation relative to the standard position. When the deviation is greater than a certain value, it will be considered that there is deviation in the bonding, and the product will identified as a defective product. [0003] The existing deviation detection method is to judge whether the deviation is based on the number of particles in the image. However, since the distribution of the number of particles cannot fully reflect the deviation state, th...
