Abstract: A map building apparatus includes a memory storing instructions, and a processor executing the instructions to obtain a plurality of frames of images that carry image information of a target environment, obtain a motion parameter of the image capture component at a capture location of each frame of the plurality of frames of images, obtain a relative displacement between capture locations of each two frames of images based on the motion parameter of the image capture component, obtain, based on the plurality of frames of images and the relative displacement, a map layer including feature points in the plurality of frames of images, and send the map layer and the relative displacement to a server. The plurality of frames of images are captured by an image capture component. The motion parameter indicates a motion status of the image capture component. The map layer is useable to build a map.
