Abstract: The present disclosure provides an obstacle recognition method, an apparatus, an electronic device, and a storage medium.

Abstract: An obstacle detection method for a robot, and the method includes: obtaining three-dimensional point cloud data of an obstacle in a first coordinate system, the first coordinate system being a coordinate system established by the robot at a current position with the robot as an origin; fusing the three-dimensional point cloud data in a robot-centered raster map to determine obstacle raster points in the raster map; performing clustering on the obstacle raster points to obtain at least one set of obstacle raster points; and generating an obstacle object in the raster map based on the set of obstacle raster points.

Abstract: A floor stain recognition method and apparatus and an automatic cleaning device are disclosed. The method includes: acquiring an RGB image of a field of view; acquiring a depth image of the field of view; acquiring an image common area of view based on the RGB image and the depth image; and acquiring spatial coordinates of a stain area based on the image common area of view. The method can detect the type and position of a stain accurately.
