Embodiment Construction

[0028] It can be seen from the background art that the detection efficiency and accuracy of the existing display panel still need to be improved. Specifically, in the prior art, one detection method is manual visual inspection, that is, the operator visually judges whether the nixie tube is good or bad, the detection efficiency is low and the detection accuracy needs to be improved; the other detection method is based on machine vision pictures The comparison method is to light up all the digital tubes on the display panel, and use a special camera to take pictures of the display panel; compare the photos taken with the pictures of the display panel that are working normally, and then detect the digital tubes that are working abnormally. The detection method of picture comparison is better for the detection effect of one or several segments of digital tubes that are not bright, but the detection effect is not ideal for the situation that multiple segments of digital tubes are b...

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...
