Solar cell panel defect detection system based on machine vision and detection method

The invention provides a solar cell panel defect detection system based on machine vision. The solar cell panel defect detection system comprises a vision camera, a vision analysis module, a PLC and aremoving device, wherein the vision camera is used for acquiring images of the surfaces of solar cell panels and transmitting the acquired images to the vision analysis module; the vision analysis module processes and analyzes the images transmitted by the vision camera and transmits a detection result to the PLC; and the PLC is connected with a sensor at the same time, the sensor counts the found solar cell panels with flaws and transmits a trigger signal to the PLC, and the PLC controls the removing device to remove the solar cell panels with the flaws. According to the solar cell panel defect detection system, an advanced algorithm and image processing software of the intelligent camera are adopted to more accurately detect the flaws which cannot be observed by the naked eyes, the image processing speed is hig
