【Abstract】 Farm crop image analysis is the basic part of information process technology of visual navigation for the autonomous agricultural robot. Automatic detection of the cropland areas under the complicated background is dealt with in this paper. Some knowledge based approaches were introduced to implement the area detection. In order to detect areas, a lowpass filter was used to preprocess the original images at first, then binary image was obtained by means of grad transformation and the morphological features of farm crop image were extracted. On this basis, cropland areas were classified. After the thin texture was moved with mathematical morphology thresholding dilation, the complete areas of cropland could be obtained. All of the algorithms proposed herein are knowledge based. Even the binary images of cropland are occluded or fragmentized, the areas can be detected efficiently and effectively. Experiments show that this method is reliable.更多还原
