Problems solved by technology

[0006] The purpose of the present invention is to propose a visual northing method based on proofreading robot angles that combines machine vision with a northerly device for the electronic compass to be easily interfered by an external magnetic field and affect the output accuracy, so as to determine the orientation angle of the robot. The installation space can be conveniently selected, effectively avoiding hard magnetic interference problems and improving detection efficiency

Embodiment

[0037] In the north indicator, the red pointer represents the baseline, that is, the zero-degree direction in the navigation coordinate system, and the straight line direction of the blue part is consistent with the direction of the robot, which is called the target line. When the compass device moves angularly with the robot, due to the earth's magnetic field, the reference line will always point in one direction, and the target line will deflect with the angular displacement of the robot. When the angle of the target line is consistent with the zero-degree direction agreed on the navigation map, the angle between the target line and the reference line represents the current angle value of the robot. When the angle of the target line is inconsistent with the zero-degree direction agreed on the navigation map, record this part of the angle difference as Δθ, and the angle between the target line and the reference line needs to be added to Δθ to represent the current angle value ...

Abstract

The invention discloses a vision north finding method based on correction of the angle of a robot. The vision north finding method comprises the steps of acquiring original image data through an image acquisition module, compressing the acquired original image data, and then extracting color components of the image; and pre-processing the extracted color components of the image through image filtering and sharpening for the extracted color component images of the image, then binarizing the pre-processed image, carrying out morphologic thinning of the binarized image, and finally solving for the angle of a blue component through Hough transform. An angle value between the two color components is obtained through angle transform, so that the facing direction for a robot can be obtained. The invention provides another method for determining the facing direction of the robot by combining machine vision and a north finder, for correcting the angle of the robot. The method according to the invention facilitates the selection of an installation space, thereby effectively avoiding the problem of hard magnetic interference.

Description

technical field [0001] The invention relates to the research field of computer image processing, in particular to a visual northing method based on the angle of a proofreading robot. Background technique [0002] With the continuous advancement of science and technology, the research of mobile robots has begun to focus on practicality, and has begun to march into various application fields. In 1994, the intelligent mobile robot developed by Tsinghua University passed the appraisal. The successful development of this robot indicates that my country has mastered five key technologies related to mobile robots: global path planning technology based on maps, local path planning technology based on sensor information, simulation technology of path planning, sensing technology and information fusion technology, intelligent Design and implementation technology of mobile robots. During this period, various robots have been developed successively across the country, including the aut...
