Abstract:A rapid detection method of crop-row based on improved Hough transformation was suggested to detect the position of crop-rows after analyzing the characteristics of field crop planting. The true color images containing crop-row and soil background were captured as the research objects. Since the histogram projection is easily disturbed by external factors and the Hough transformation has a low speed, a combination of these two algorithms was developed. First, a true color image of field crops was processed with 2G—R—B gray and OTSU to separate plants from soil. Second, the noise was eliminated by fast median filtering algorithm, and then the image was divided into ten horizontal strips to get the anchor points according to the geometric distribution of the crop-rows. Finally, the centerline of crop rows was obtained by Hough transformation using those points. Test results show that the processing speed of the improved Hough transformation method is four times faster than that of original Hough transformation with the similar positioning accuracy, and the centerline detected can highly match the crop-row. |
Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
