  • Publication number: 20220273152
    Abstract: An obstacle identification method includes: acquiring an environmental image sent by an image acquisition component; determining contour information of an object acted on by a line laser by using pixel coordinates of reflected light in the environmental image; and when a contour indicated by the contour information is the contour of an obstacle, determining that the object acted on by the line laser is the obstacle. Since a first line laser emitter and the image acquisition component are jointly used to acquire environmental images, the image acquisition component may still collect an image of reflected light of the line laser even when there is relatively little ambient light. Therefore, it is ensured that obstacles may be identified even when there is relatively little ambient light. An obstacle identification apparatus, a self-moving device, and a storage medium are disclosed as well.
