Abstract: An automatic working system, an automatic travelling device (1) and a control method therefor, and a computer readable storage medium. The control method comprises: obtaining a photographed image in an HSV format; collecting statistics about the number or proportion pixRange of pixel points of which the chromaticity is within a preset range in the photographed image; and if the pixRange is smaller than value1, determining that the photographed image belongs to a non-lawn area, wherein value1 is a preset first threshold. The photographed image photographed by the automatic travelling device (1) can be processed and analyzed, and whether the photographed image belongs to the lawn area or not is determined by analyzing the number or proportion pixRange of pixel points of which the chromaticity is within a preset range in the photographed image. The preset range can reflect a green or approximately green range in chromaticity. Whether the automatic travelling device (1) moves to the boundary (2) or the outside of the working area or not is determined by analyzing the chromaticity of the pixel points in the photographed image, the operation is more convenient, and the control is more sensitive and effective.
