The invention provides an image detecting method and device. The image detecting method includes the steps of obtaining a to-be-detected film graph, wherein the to-be-detected film graph comprises a plurality of discontinuous film sprite graphs; recognizing a first detecting area with the continuous complete film sprite graphs in the film graph; detecting the film sprite graphs of the first detecting area according to a preset first detecting rule. By means of the scheme, the area of the continuous film sprite graphs can be actively recognized, and detecting is conducted according to the corresponding detecting rule. Thus, when the method is applied for detecting the Dummy BM area of a color film substrate, the gap area between black matrix films can be prevented from being detected as one part of the black matrix films, and it can be avoided that the color film substrate is falsely detected and scrapped by mistake.
Description
technical field [0001] The invention relates to the field of product quality detection, in particular to an image detection method and image detection equipment. Background technique [0002] The color filter substrate is the main device used to realize color display and is an important part of liquid crystal display. [0003] The existing color filter substrate generally includes: a black matrix (BM), a color photoresist (RGB), an insulating cover layer (OC), a conductive layer and a spacer (PS) supporting the thickness of the liquid crystal cell. The pattern (Pattern) formed by the BM layer and the RGB layer is called ColorPattern. In the production of BM and RGB processes, defects such as missing color patterns will inevitably occur. The defects generated in each process of the color filter substrate can be detected by an optical inspection machine, so as to timely intercept defective products from flowing into subsequent processes, and avoid huge cost waste. .
