High-definition electronic screen production quality intelligent monitoring and analyzing system based on machine vision

Abstract

The invention discloses a high-definition electronic screen production quality intelligent monitoring and analyzing system based on machine vision. The key target part monitoring system based on the image recognition analysis technology comprises a key part monitoring selection module, a lamp bead basic information acquisition and analysis module, a lamp bead performance test information acquisition and analysis module, a lamp bead production qualification analysis module and an analysis result transmission terminal. According to the invention, the appearance information and the performance test information corresponding to the lamp beads in the electronic advertisement screens are collected, and the qualified rate corresponding to the lamp beads in the electronic advertisement screens and the qualified rate corresponding to the electronic advertisement screens are analyzed based on the collected appearance information and the performance test information. The problem that the quality monitoring of the lamp beads in the electronic advertisement screen has certain one-sidedness in the prior art is effectively solved, the situation that the use scene of the prior art is too limited is avoided, the failure rate in the use process of the electronic advertisement screen is effectively reduced, and the method has great practical significance.

Description

technical field [0001] The invention belongs to the technical field of product quality monitoring, and relates to a machine vision-based high-definition electronic screen production quality intelligent monitoring and analysis system. Background technique [0002] With the further development of semiconductor lighting, LED has been more and more widely used in road lighting, advertising and other fields, especially with the rapid development of multimedia information technology in recent years, the demand for electronic advertising screens has also increased. In order to ensure the delivery effect of the electronic advertising screen, it is necessary to monitor the quality of the electronic advertising screen. As the main component of the electronic advertising screen, the lamp bead is of great significance to its quality monitoring. [0003] The current quality monitoring of lamp beads in electronic advertising screens is mainly used to monitor the conventional parameters an...

Problems solved by technology

[0003] At present, the quality monitoring of lamp beads in electronic advertising screens is mainly used to monitor the conventional parameters and performance of each component of the lamp beads, such as monitoring the appearance cleanliness, color temperature, luminous flux, electrical performance and optical performance of the lamp beads. , and many application scenarios of advertising screens are outdoors, and the environment is not in a static state. Obviously, the current quality monitoring of lamp beads in electronic advertising screens is still somewhat one-sided. On the one hand, the use scenarios corresponding to the current technology are too Due to the limitation, the influence of the external environment on the quality of the lamp beads is not considered, so that the stability and reliability of the operation of the lamp beads in the subsequent use of the electronic advertising screen cannot be guaranteed, and the corresponding life of the lamp beads under various environmental conditions cannot be intuitively displayed. , and cannot effectively reduce the failure rate during the use of electronic advertising screens; on the one hand, the current technology cannot highlight the quality status of lamp beads in actual use scenarios, and thus cannot improve the quality monitoring effect of lamp beads in electronic advertising screens; On the other hand, it is still unable to provide effective production improvement directions for electronic advertising screen manufacturers, and thus cannot improve the operating efficiency of electronic screen advertising manufacturers.
