Parking information obtaining method and device and parking method and device

The invention provides a parking information obtaining method and device and a parking method and device. The parking information obtaining method comprises the steps of obtaining an aerial view of the position where a vehicle to be parked is located; inputting the aerial view into a pre-constructed information acquisition model to obtain parking information, wherein the information acquisition model is pre-established based on a multi-task neural network, the multi-task neural network comprises a shared coding layer and a plurality of task neural networks, and the plurality of task neural networks share the shared coding layer. Visibly, according to the scheme, the information acquisition model is constructed in advance based on the multi-task neural network, the aerial view is input into the information acquisition model, the parking information can be directly obtained, only the information acquisition model needs to be operated, and few computing resources are occupied, so that the information acquisition
