  • Patent number: 10739781
    Abstract: The present disclosure provides a method, apparatus, and terminal device for cliff detection. The method includes: obtaining a detection distance matrix of distances between a camera of a target robot and a ground within a preset detection angle range collected by the camera; obtaining a difference matrix obtained by subtracting a theoretical distance matrix from the detection distance matrix; counting an amount of elements in the difference matrix being greater than a preset first threshold; and determining a cliff is detected if the counted amount of the elements is greater than a preset second threshold. Through the overall consideration of the distance matrix of the distances within the detection angle range, even if a certain part of the ground changes its external conditions such as the color depth and the lightness, the influences on the overall detection result is extremely limited, which makes the detection result more accurate and reliable.
