Problems solved by technology

However, in paddy fields, the identification and extraction of plant image information is often affected by factors such as the complex background environment of the paddy field, changes in water surface illumination, and variable growth forms of crops.
Therefore, it will be very difficult to identify and locate crops based on machine vision in the paddy field environment

Abstract

The invention relates to a rice plant identifying and positioning device based on infrared sensors. The device comprises a connecting part, two mounting boxes, two seedling shifting parts, two sets ofinfrared radiation sensors, an infrared distance measuring sensor, a data processing system, and a power supply. The two mounting boxes are mounted on the left end and the right end of the connectingpart in a left-right symmetry mode. The two seedling shifting parts are fixed in the inner sides of the fronts of the two mounting boxes in a left-right symmetry mode. Each infrared radiation sensorcomprises a transmitting end and a receiving end which are separately mounted on the front side of one of the two mounting boxes. The infrared distance measuring sensor is mounted on the front side ofone of the mounting boxes. One set of infrared radiation sensors, the infrared distance measuring sensor, and the other set of infrared radiation sensors are sequentially arranged in order of high and low in the vertical direction. The invention further relates to a rice plant identifying and positioning method based on the infrared sensors. The device and method can accurately identify and position rice plants, have real-time and accuracy, and belong to the mechanical design and intelligent control technology of agricultural equipment.

Description

technical field [0001] The invention belongs to the field of farmland crop identification, in particular to an infrared sensor-based rice plant identification and positioning device and positioning method, and relates to mechanical design and intelligent control technology of agricultural equipment. Background technique [0002] Inter-plant weeding has always been the key problem of mechanized weeding. Rice cultivation in my country is mostly planted in paddy fields. In the actual production of mechanized transplanting in paddy fields, due to the different amount of seedlings taken, missed transplanting and floating seedlings, it is difficult for the rice to be completely arranged in a straight line and the distance between the plants is difficult to be evenly distributed. Therefore, accurate identification and positioning of rice plants is the prerequisite for realizing precise transplanting and solving mechanical weeding between rice plants. [0003] In view of this key p...
