Problems solved by technology

[0003] In the related technology, the scanning device can be positioned by GPS, and the scanning device is on a certain route, and the object is scanned by reciprocating motion, but in this solution, the building has a great influence on the GPS signal, and it is difficult to guarantee the validity of the signal , which in turn limits the usage scenarios of scanning devices
In addition, using a single-line laser sensor to achieve autonomous guidance requires installing a reference object near the track so that the scanning device can drive according to the reference object. When the scanning distance is long, it increases the difficulty of on-site work

Abstract

The disclosure provides an autonomous guiding method and device for a scanning device, and a scanning device, and relates to the field of autonomous guiding. The method includes: judging whether landmark line information can be identified based on ground image information, wherein an image sensor is installed on the scanning device, and the image sensor is used to obtain ground image information; if yes, determining whether the scanning device is running Otherwise, determine whether the RTK trajectory information of the scanning device can be obtained, wherein, the RTK sensor is installed on the scanning device, and the RTK sensor is used to obtain the RTK trajectory information of the scanning device; if possible, based on the RTK trajectory information corresponding to the RTK sensor The position information of the mobile station determines the target offset during the operation of the scanning device; based on the target offset, the autonomous guidance of the scanning device is realized. The disclosure realizes autonomous guidance of the scanning device based on multi-sensor fusion, and improves the automation degree of the scanning device.

Description

technical field [0001] The present disclosure relates to the field of autonomous guidance, and in particular to an autonomous guidance method and device for a scanning device, and a scanning device. Background technique [0002] Autonomous guidance means that the scanning device realizes autonomous scanning path planning and movement according to a certain route. In the field of security inspection, automatic guidance can realize the intelligence of scanning equipment, reduce the degree of personnel participation, and improve the automation of equipment. [0003] In the related technology, the scanning device can be positioned by GPS, and the scanning device is on a certain route, moving back and forth to scan the object to be inspected, but in this solution, buildings have a greater impact on the GPS signal, and it is difficult to guarantee the validity of the signal , thereby limiting the usage scenarios of the scanning device. In addition, to use a single-line laser sen...
