An agricultural robot positioning method and system

Abstract

The invention relates to a positioning method for an agricultural robot, which comprises the following steps: installing a positioning antenna and a directional antenna on the left and right sides of the agricultural robot; The horizontal distance is defined as the actual horizontal deviation; the actual position is the intersection of the plane formed by the positioning antenna and the directional antenna that are parallel to each other, the center line of the agricultural robot and the set horizontal plane; obtain the The vector from the set point to the actual position; the positioning position of the agricultural robot is determined according to the vector from the set point to the actual position and the horizontal actual deviation. The present invention performs error correction on the positioning position through the inclination angle, thereby improving the positioning accuracy of the agricultural robot.

Description

technical field [0001] The invention relates to the field of navigation, in particular to a method and system for positioning an agricultural robot. Background technique [0002] With the improvement of the level of modern science and technology and China's requirements of the times for the modernization of agriculture and rural areas. The modernization and intelligence of agricultural machinery is one of the important development directions. The automatic navigation of agricultural machinery is one of the key technologies for the automation and intelligence of modern agricultural machinery. In the process of agricultural machinery navigation, high-precision positioning of agricultural machinery is the premise of navigation operations. When agricultural machinery is operating in the field, due to the large undulation of the ground, the agricultural machinery has a phenomenon of left-right swing. At this time, the positioning information obtained by the GNSS receiver will d...

AI Technical Summary

Problems solved by technology

When the agricultural machinery is working in the field, due to the large undulation of the ground, the agricultural machinery has a left-right swing phenomenon. At this time, the positioning information obtained by the GNSS receiver will deviate with the swing of the agricultural machinery, which will affect the positioning accuracy and thus affect the navigation accuracy.
