Design And Implement Of Portable Intelligent Colony Counting System

Colony detection is an important method of quality inspection in agriculture, food and medicine industries. But it is a hard and boring work to detect colony using the method of traditional visual check. Currently, most of the colony automatic counter is developed based on PC platform which has poor portability and could not meet the requirements of field detection. With the rapid development of embedded technology, the embedded device which has the advantages of low cost and good portability has been used more and more widely.An embedded intelligent colony counting system based on ARM was designed in this paper and a kind of embedded colony automatic counter prototype was developed. The S3C6410 chip was used as the CPU of the system. The wide-angle infrared camera was chosen for colony image acquisition and a customized Windows CE 6.0 kernel was designed to improve system efficiency. Prototype structure and the lighting system were well designed for the best results.In this paper, an intelligent automatic colony counting algorithm was developed with the OPENCV computer vision library and was tested both on PC and ARM platform. An algorithm of automatic edge detection was developed to improve the detection accuracy based on Hough Transform. We also proposed a colony automatic counting algorithm based on an improved iterative erosion algorithm to avoid the redundant calculations. The average deviation of counting results was controlled in 6% comparing with gross inspection results.In a word, some significant research and attempt were proposed in the study of colony counting algorithm. A kind of embedded automatic colony counter prototype was developed and the intelligent colony counting algorithm was successfully transplanted on the target embedded platform. Therefore, all of these works not only have theoretical significance but also have extensive practical value for instrument development application.
