Strawberry recognition is a very important part in strawberry harvesting robot. The method being used is based on the features (such as area, compact, etc.) of the image area. It is effective for single strawberry recognition, but unsatisfactory for complex situation, in which the strawberry may be hidden by other objects or covered each other. In this paper, we put forward a new method for strawberry recognition based on Hough transform. It labels the region of the image after segmented, gets the minimum enclosing rectangle (MER) and recognizes it based on Hough transform using the contour of strawberry in the MER. The experimental results show that the strawberry recognition method based on Hough transform is effective both for single strawberry and complex situation when the strawberry contour loss is less than 1/2. The recognition warp on average is 4.8% and can meet the requirement of strawberry harvesting robot.
