| Abstract: | In order to avoid damaging apples and branches caused by manipulator during the picking operation,for the absence of attitude information,an apple's attitude estimation method was put forward.After the apple object was segmented from background with the two-step algorithm based on the characters of color and texture,the freeman chain code algorithm was used to extract one-pixel fruit contour.Then least distance method,least slope variance method and three collinear points' method were given,and the recognit... |
