基于机器视觉的兰花几何参数测量方法OA北大核心

In order to rapidly measure the geometric parameters of orchid,an image acquisition platform was built and a set of algorithm for measuring geometric parameters of orchid flower was designed with the Golden Phalaenopsis as the re-search object.The algorithm includes Canny-Harris algorithm to detect orchid corner point,K-means algorithm and RGB threshold segmentation algorithm to segment orchid in picture,and MER algorithm and traversal algorithm to meas-ure specific geometric parameter of orchid.Through recognizing and testing orchid with the algorithm,the test results show that it only takes about 10 s to measure a single orchid plant,the algorithm measure rate is nearly 60 times higher than the manual measurement rate,and the measurement data can provide a judgment basis for orchid selection and breeding.
