Problems solved by technology
[0003] Root cutting and fertilization after wheat emergence and greening can increase wheat yield by 10-20%. At present, root cutting and fertilization operations are mainly done manually, with low efficiency and high cost. The development of automatic root cutting and fertilization devices is of great importance to the implementation of this agronomy. Significance, a kind of barley seedling root cutting and fertilization automatic line image recognition method that the present invention proposes has great significance to improving the efficiency of root cutting and fertilization

The invention discloses a wheat seedling root cutting fertilization automatic specific row image recognition method. The method comprises the steps that (1) image processing is carried out according to the color value of a wheat seedling image; (2) from the vertical center line of the image wheat seedling points are parallelly searched to both sides from bottom to top, so as to acquire left and right wheat seedling point sets; (3) filter fitting is carried out the left and right wheat seedling point sets to generate the middle straight line of the left and right point sets; and (4) the vertical center line of the image and the generated middle straight line are compared to output adjustment action. According to the invention, the set wheat seedling color is used for image processing; the image center line is used for reference to generate the midline between wheat seedling rows and output action; the speed of processing and recognition of the wheat seedling image is improved; and the working efficiency of wheat root cutting fertilization automatic specific row is improved.
Description
technical field [0001] The invention relates to the field of intelligent agricultural information processing, in particular to an automatic line-to-line image recognition method for root cutting and fertilization of wheat seedlings. Background technique [0002] China is a large agricultural country, and agricultural issues are fundamental issues related to China's economic and social development. Under the already small base of my country's per capita arable land area, the per capita arable land area is decreasing year by year. Therefore, it has become an inevitable trend of agricultural development to develop intelligent precision agriculture and increase the output rate per unit of land. Wheat is the staple food with the largest planting area in my country. Increasing wheat production is of great economic and strategic significance to the development of the national economy and the protection of national food security. [0003] Root cutting and fertilization after wheat ...
