Abstract: In a safety boundary generation method, an image of a surrounding environment captured by a camera in a head-mounted display device is received. Three-dimensional reconstruction is performed based on the image of the surrounding environment to obtain a three-dimensional environment model. The three-dimensional environment model indicates a three-dimensional representation of the surrounding environment of a user that wears the head-mounted display device. Ground detection on the three-dimensional environment model is performed to obtain a plurality of ground boundary points. Each of the plurality of ground boundary points is an intersection point between a ground plane and an obstacle in the surrounding environment. A safety boundary is determined based on the plurality of ground boundary points. A region enclosed by the safety boundary is a safety region for the user to interact with the head-mounted display device.
