Display panel detection method, electronic equipment and storage medium

Abstract

The invention discloses a display panel detection method, electronic equipment and a storage medium, and the display panel detection method comprises the steps: obtaining N panel pictures after all display tubes are switched on and are only switched on once; calculating the centroid positions of the nixie tubes in the N panel pictures according to the positions of the lightened display tubes in the panel pictures, and judging whether the N panel pictures have the centroid positions or not and whether the centroid positions in the panel pictures are different or not; if at least one panel picture in the N panel pictures does not have the centroid position, determining that the display tube conducted in the panel picture without the centroid position is displayed abnormally; if the centroidpositions exist in the N panel pictures, and the centroid positions are different, determining that all the display tubes display normally; and if the centroid positions exist in the N panel picturesand the centroid positions in at least two panel pictures are the same, determining that all display tubes in the panel pictures with the same centroid positions are displayed abnormally. The detection efficiency of the display panel can be improved.

Description

technical field [0001] The invention relates to the field of machine vision, in particular to a detection method of a display panel, electronic equipment and a storage medium. Background technique [0002] With the development of machine vision technology, the testing industry is increasingly using machine vision to replace manual inspection. For most servo products, there is a display panel. Due to the cheap and durable characteristics of digital tubes, most of the existing display panels are digital tube display panels, which display data by turning on and off multi-segment digital tubes. [0003] One method of nixie tube detection is manual visual inspection, that is, the inspector judges whether the nixie tube is displayed normally, which is time-consuming and laborious, and the accuracy needs to be improved. Another way is to use a special camera for image detection to eliminate the uncertainty of manual detection. However, the existing detection methods lack versatil...

[0003] One way of nixie tube detection is manual visual inspection, that is, the inspector judges whether the nixie tube is normal or not, which is time-consuming and laborious and the accuracy needs to be improved

Another way is to use a special camera for image detection to eliminate the uncertainty of manual detection. However, the existing detection methods lack versatility, and the effect is better when the detection digital tube is not bright, and it is difficult to detect due to continuous welding The situation that the digital tubes are bright at the same time caused by the reason, that is, the detection effect of the existing technology still needs to be improved
