Implementation method of agricultural robot based on GPS positioning and automatic obstacle avoidance

Abstract

The invention discloses an agricultural robot implementation method based on GPS positioning and automatic obstacle avoidance. The method comprises the steps: obtaining positioning information througha GPS positioning module, carrying out path planning, and obtaining an optimal path; acquiring road condition image information right ahead the agricultural robot by using a camera module, and acquiring the road condition information right below the agricultural robot by using an infrared sensing module; calculating a relative position of an obstacle and the agricultural robot and progressible positions in a road surface, and screening out an optimal position from the multiple progressible positions; making the agricultural robot avoid the obstacle to reach the optimal position; and in combination with path information of the GPS positioning module, making the agricultural robot continue to advance to the next optimal position point till that the agricultural robot reaches a target position. The agricultural robot can be ensured to work normally when facing the obstacle, and working efficiency of the agricultural robot is improved.

Description

technical field [0001] The invention relates to the field of automatic driving of agricultural robots, in particular to an implementation method of an agricultural robot based on GPS positioning and automatic obstacle avoidance. Background technique [0002] Modern agriculture generally has a large scale and relatively open land, and operations often need to be carried out in all directions, which will consume a lot of time on the way back and forth, reducing production efficiency. For machines, human labor has obvious disadvantages in large-scale agricultural production: 1. The time of human labor is spent on the journey, which reduces production efficiency and increases input; 2. Agricultural operations are repetitive tasks , is not only boring, but also has a large workload, and the round-trip operation requires a lot of labor. 3. The positioning is not accurate enough, large-scale farmland, it is difficult for people to identify specific coordinate points. With the con...
