摘要： A self-working system, a self-walking device, a control method therefor and a computer-readable storage medium are disclosed, wherein the control method may include the following steps: acquiring a captured image; processing the captured image to acquire a processed image; segmenting the processed image into at least one sub-region; respectively acquiring a representative pixel point PLn of each sub-region; calculating, in the processed image, the number of sub-regions of which the representative pixel point PLn is located below a comparison pixel point PC and marking same as the number Nb of special sub-regions, PC being a preset comparison pixel point; if Nb≤1, judging that there is a boundary (2) or obstacle in the distance of the captured image; if Nb>1, judging that there is a boundary (2) or obstacle in the vicinity of the captured image. The subsequent work of the self-walking device is directly judged by means of machine vision, which is more convenient and also makes the control more sensitive and effective. Furthermore, an erroneous judgement caused by recognition of a boundary (2) or obstacle on a slope can be effectively avoided, so that the control is more accurate.

摘要： A self-working system, a self-walking device (1) and a method for controlling same, and a computer-readable storage medium. The control method comprises: acquiring a captured image; processing the captured image to acquire a processed image; segmenting the processed image into at least one sub-region; calculating the size An of each sub-region, respectively; counting the number of sub-regions with An>V in the processed image, and marking same as the number Nb of special sub-regions, wherein V is a preset quantity threshold; if Nb≤1, judging that the captured image belongs to a lawn region; and if Nb> 1, judging that the captured image belongs to a non-complete lawn region. If it is judged that a captured image belongs to a non-complete lawn region, it can be determined that there is a large obstacle or a boundary (2), etc. Whether the self-walking device (1) encounters an obstacle or a boundary (2) can be analyzed by analyzing a captured image, such that the operation is easier, and the control is more sensitive and effective.
