Embodiment 1

[0044] figure 1 It is a schematic structural diagram of a target positioning device for a following robot according to an embodiment of the present disclosure.

[0045] Such as figure 1 As shown, a target positioning device for following a robot in this embodiment includes:

[0046] a heat radiation module, which is used to generate heat radiation;

[0047] An infrared image acquisition module, which is used to collect infrared images generated by thermal radiation;

[0048] Laser scanning module, which is used to collect scene depth point cloud data;

[0049] The data processing module is connected to the infrared image acquisition module and the laser scanning module respectively, and is used to receive the infrared image generated by thermal radiation and the depth point cloud data of the scene, and to locate the target.

[0050] Wherein, in the embodiment of the present disclosure, all heating strips are in a heating state.

[0051] Compared with other video images, i...

Embodiment 2

[0094] The positioning method of the target positioning device following the robot in this embodiment includes:

[0095] Receive infrared images and scene depth point cloud data;

[0096] Detect the edge curve of the heating strip in the infrared image;

[0097] Among them, the process of detecting the edge curve of the heating strip in the infrared image is:

[0098] Binarize the gray value of each pixel in the infrared image to obtain the first unit color bitmap;

[0099] performing denoising processing on the first unit color bitmap to obtain a second unit color bitmap;

[0100] The color bitmap of the second unit is segmented by multi-connection method to obtain the edge curve of the heating strip.

[0101] Calculate the average value of all pixel coordinates on the edge curve of the heating strip to obtain the center coordinate of the heating strip, and then obtain the width of the heating strip and the distance between the heating strips;

[0102] Use the ratio of th...

Abstract

The invention provides a target positioning device and method for follow robots. The target positioning device for the follow robots comprises a thermal radiation module, an infrared image acquisitionmodule, a laser scanning module and a data processing module, wherein the thermal radiation module is arranged on a target; the data processing module is used for detecting edge curves of heating strips in an infrared image, solving an average value of all the pixel coordinate values on the edge curves of the heating strips so as to obtain center coordinates of the heating strips and then obtainheating strip widths and heating strip distances; when the thermal radiation module is searched, calculating an average value of center point coordinates of all the heating strips and taking the average value as an image coordinate of the target so as to solve direction information of the target under the infrared image; mapping field scene deep point cloud data to the infrared image so as to obtain distance information corresponding to all the pixels of the infrared image; recognizing an overall profile of the target at a target direction of the infrared image; and carrying out statistical analysis on all the pieces of distance information corresponding to the pixels of the target and carrying out average value calculation to obtain a position of the target.

Description

technical field [0001] The present disclosure belongs to the technical field of robots, and in particular relates to a target positioning device and method for a following robot. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] Follow-the-walk is a typical man-machine cooperation mode, which enables the robot to follow the movement of people in factories, large supermarkets, warehouse logistics and other environments, and cooperate with humans to complete tasks such as material transportation, obstacle removal, and emergency rescue. Following the technological development of robots and relying on the support of human target recognition technology, the common human target recognition methods are mainly two recognition methods based on visual information or laser information. When the robot is following along in a complex environment, the v...
