Title:
AUTOMATIC WORKING SYSTEM, AUTOMATIC TRAVELLING DEVICE AND CONTROL METHOD THEREFOR, AND COMPUTER READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/042487
Kind Code:
A1
Abstract:
An automatic working system, an automatic travelling device and a control method therefor, and a computer readable storage medium, the control method comprising: acquiring a photographed image of at least part of a boundary; on the basis of a fence pattern on the photographed image, determining whether the boundary has been reached or approached; and, after determining that the boundary has been reached or approached, the automatic travelling device stops advancing forward and rotates a preset angle, and then continues to advance and work. The boundary can be built on the ground, such that the automatic travelling device recognises the boundary and performs the next step of control. The fence pattern on the photographed images photographed by the automatic travelling device enables the automatic travelling device to better distinguish the boundary and the ground in the recognition process so that control is more sensitive and the error rate is lower.
