Problems solved by technology

[0002] When field robots such as lawn mowing robots or security patrol robots move according to the planned path, their actual movement trajectory deviates from the set working boundary or working path. Sometimes this error will have a cumulative effect and cause serious consequences. Therefore, it is necessary to Monitor the position of the field robot and its motion path in order to correct the motion state of the robot

Abstract

The invention belongs to the field of image processing, and particularly relates to a method for monitoring the position and the movement path of a field robot. The method mainly comprises the following steps: 1) identifying the number identity of each field robot; 2) calibrating a shooting height and a shooting posture of a shooting device; 3) identifying an image shot by the shooting device andcarrying out distortion correction; and 4) selecting an original point to establish a coordinate system, identifying the position of the field robot according to the number identity of each field robot, and identifying the movement path of the field robot in combination with the time relationship of the key frames. The field robot is identified by using the colors of the fixed spherical marker,s and compared with identifying the robot by using contour features, the huge calculation workload can be avoided, so that the calculation speed and the monitoring efficiency can be improved; The image distortion correction method provided by the invention is simple in algorithm, and is beneficial to controlling the processing scale of the position image data of the field robot, thereby improving theprocessing speed.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a method for monitoring the position of a field robot and its motion path. Background technique [0002] When field robots such as lawn mowing robots or security patrol robots move according to the planned path, their actual movement trajectory deviates from the set working boundary or working path. Sometimes this error will have a cumulative effect and cause serious consequences. Therefore, it is necessary to Monitor the position of the field robot and its motion path, so as to correct the motion state of the robot. In addition, in a field with multiple robots moving, such as a robot team competition, timely and accurate acquisition of the position and movement path of each robot is also very necessary for research and formulation of confrontation strategies. Contents of the invention [0003] The purpose of the present invention is to provide a method fo...
