Problems solved by technology
Most of the traditional steel plate surface defect detection is manually searched and marked, and the steel plate needs to be turned over, that is, the off-line detection method. This method has low detection accuracy, lags in reflecting problems, consumes manpower and material resources, has low detection efficiency, and has false detections and missed detections. shortcoming
In addition, suction cups are required in the process of turning over the steel plate, and there are certain safety hazards in the operation process.

The invention discloses an online image detection system for steel plate surface defects. The system comprises a management module, a control analysis module, a 3D space acquisition and processing module, an object form visualization module and an intelligent defect identification statistical analysis module, the management module manages and controls operation of a steel plate surface treatment production line, controls the analysis module to store detection data, identifies and analyzes collected images, and gives steel plate grade classification; the 3D space acquisition and processing module detects the surface defect area and depth of the steel plate by adopting a 3D structured light imaging principle; the object form visualization module is used for displaying the suspected defect position and the actual state of the steel plate in real time; and the defect intelligent identification statistical analysis module identifies and counts the suspected defects. The system overcomes the defects of traditional steel plate surface defect detection, realizes simultaneous detection of two surfaces of the steel plate, can quickly and accurately detect the surface defects of the steel plate, improves the detection precision and efficiency, avoids error detection and missing detection, and avoids potential safety hazards of detection operation.
Description
technical field [0001] The invention relates to the technical field of detection, in particular to an online image detection system for surface defects of steel plates. Background technique [0002] In the process of steel plate surface treatment, surface defects such as pitting and peeling are caused by raw materials, corrosion and other reasons. Therefore, it is necessary to carry out steel plate surface inspection and classification according to the distribution and degree of defects on the steel plate surface. Most of the traditional steel plate surface defect detection is manually searched and marked, and the steel plate needs to be turned over, that is, the off-line detection method. This method has low detection accuracy, lags in reflecting problems, consumes manpower and material resources, has low detection efficiency, and has false detections and missed detections. shortcoming. In addition, suction cups are required in the process of turning over the steel plate, ...
