Abstract: The present disclosure discloses an end-to-end stereo image compression method and device based on bi-directional coding, the method comprises: extracting inter-view information as prior from input left-view and right-view images by a neural network, sending the prior into left-view and right-view encoders simultaneously to jointly encode the input left-view and right-view images to generate left-view and right-view bit streams; and extracting inter-view information as the other prior from the generated left-view and right-view bit streams by the neural network, sending the other prior into left-view and right-view decoders simultaneously to jointly decode the left-view and right-view bit streams to generate reconstructed left-view and right-view images. The device comprises constructing a bi-directional coding structure for acquiring the bi-directional inter-view information and compress the stereo image based on the bi-directional inter-view information by the neural network.

Abstract: A parking space navigation method is provided. The method includes obtaining and displaying a parking space distribution map of a parking lot by using a mobile terminal; querying current existing vacant parking spaces of the parking lot from a server; marking the current existing vacant parking spaces on the parking space distribution map; determining a target vacant parking space from the marked current existing vacant parking spaces; obtaining, from the server, a first position of a terminal node associated with the mobile terminal when the terminal node is placed on a vehicle; and drawing, on the parking space distribution map, a navigation route from the first position to the target vacant parking space.
