- Abstract
Solar cells were used in greenhouses to generate enough heat to keep vegetables warm in the cold. This paper takes the solar cells various appearance defects simultaneous detection system as the research plant. The appearance defects can be divided into four categories: grid defects, front defects, back defects and grid defects, which will seriously affect the quality of solar cells. In order to detect all appearance defects at the same time, a detection system based on machine vision was designed in this paper. A prototype has been developed and 10,000 pieces of 156×156 cells have been tested. The test results show that the false alarm rate of defects is 3.68%, the detection missing rate is 0.12%, and the single cell detection time is 1.35S. The system can detect many kinds of defects of cells at the same time and it is accurate, effective, efficient and reliable.
