A method of controlling the cutter of tea picking machine based on vision detection

Abstract

The invention discloses a method for controlling a cutting knife of a tea-leaf picker based on visual inspection. The method comprises the steps that a camera is mounted on the right ahead portion of the tea-leaf picker, the visual angle of tea leaf picking condition of a leaf inlet is shot, two areas which are obviously different from tea trees in color and are different from each other in color are marked on the cutting knife of the tea-leaf picker in advance, the number of pixel points in the two areas of a collected image are detected to judge the relative position of the cutting knife and the crowns of the tea trees, and control signals are output to automatically adjust the position and the angle of the cutting knife. According to the method, a computer visual inspection technology is used for judging the position of the cutting knife relative to the crows of the tea trees, the control signals are output in time to automatically adjust the position and the angle of the cutting knife, the cutting knife is made to be matched with tea crown faces, the tea leaf picking quality and the tea leaf picking efficiency are improved, and meanwhile the requirements for the terrain of a tea garden and the flatness of the crowns of the tea-leaf picker are lowered.

Description

technical field [0001] The invention belongs to the application of computer vision technology, computer control technology and mechanical manufacturing technology in the control of tea picking machine cutters, and in particular relates to a method for controlling tea picking machine cutters based on visual detection. Background technique [0002] According to the data provided by China Business Intelligence: In 2012, according to the data reported by 18 tea-producing provinces, my country’s tea planting area was 35.78 million mu, a year-on-year increase of 2.013 million mu. It is a veritable tea plantation and production country. However, traditional tea production is mostly based on the family unit, and the picking and processing of tea are mainly done by hand, which is a labor-intensive industry. From the perspective of tea picking, on the one hand, the high cost of manpower picking increases the production cost of tea; on the other hand, due to the short time of tea picki...

Problems solved by technology

However, due to the unevenness of the fields on both sides of the tea ridge, as well as changes in the height of the crown of the tea tree and the growth of the buds, the quality and efficiency of tea picking will be seriously affected.
