基于LabVIEW的工件外测量与颜色识别软径系统设计.

In order to test the quality, to sort workpieces depending on their sizes, and to identify the different colors of workpieces and sort them, a software system of workpieces diameter measurement and color recognition based on Lab VIEW was designed. Images were collected and saved by the USB camera, the images were processed, the processing methods included image grayscale, contrast and brightness adjustment, various filtering function and so on; the workpiece diameter measurement and color recognition were implemented. Workpieces that the diameters were different from the sample can be filtrated. Through analyzing the colors of red, green and blue histograms of samples and workpieces to calculate comprehensive color difference, color recognition was realized. The screw was taken as an example, experimental results show that the system can quickly measure the workpiece diameters, has accurate recognition rate and high precision. The system has certain reference value for detecting the size of the objects and color sorting in industrial and agricultural production. [ABSTRACT FROM AUTHOR]
