Embodiment Construction
[0037] Please refer to figure 1 and figure 2 , are respectively the structural module diagram and the external result schematic diagram of the intelligent lawnmower in an embodiment.
[0038] The intelligent lawn mower includes a body 100 , standard color components 200 , an image acquisition unit 300 , an image correction device 400 and a control device 500 . Wherein, the standard color piece 200 is located in the camera field of view of the image acquisition unit 300 , and the image correction device 400 is connected to the control device 500 .
[0039] The intelligent lawn mower needs to recognize the objects in the external environment during the working process, so as to avoid the phenomenon of wrong cutting when the objects in the external environment are not the target vegetation. In this embodiment, the standard color element 200 is set in the field of view of the image acquisition unit 300 , and the image acquisition unit 300 is set on the body 100 to collect image...

The invention relates to an intelligent lawn mower. The intelligent lawn mower comprises a body, an image acquisition unit arranged on the body and used for collecting image information of the external environment; a standard color part arranged in the vision field of the image acquisition unit; an image correction device used for comparing the standard color part image information acquired by the image acquisition unit with stored standard color data, acquiring a color deviation value generated in a process that the image acquisition unit acquires the external environment image information, and carrying out color correction upon the external environment image information according to the acquired color deviation value; and a control device used for controlling the working status of the intelligent lawn mower according to the external environment image information after color correction. The invention also provides a control method of the intelligent lawn mower. With the intelligent lawn mower and the method provided by the invention, vegetation misjudgment rate can be effectively reduced.
Description
technical field [0001] The invention relates to the field of automatic machinery, in particular to an intelligent lawn mower and a control method thereof. Background technique [0002] A lawn mower is a semi-automatic mechanical tool for cutting grass, vegetation, etc., trimming weeds and treating flat green lawns. Lawn mowers are widely used because of their simple operation and saving manpower and time. [0003] During the working process of the lawn mower, some image information can be collected by installing a camera, and based on these image information, it can be judged whether the vegetation in front is the object of cutting and pruning. However, when the vegetation has chromatic aberration due to environmental influences (such as light, reflection, etc.), the image information collected by the camera will deviate from its original true color, which will cause the lawn mower to misjudge the vegetation. Contents of the invention [0004] Based on this, it is necess...
