Visual parking space lossless filtering method and device and storage medium

The invention relates to a visual parking space lossless filtering method and device and a storage medium, and the method comprises the steps: obtaining the real-time relative position information of a static parking space and a camera, and determining the original confidence of a visual parking space image captured by the camera; and performing lossless filtering on the visual parking space image captured at the current moment based on the visual parking space image captured by the camera at the current moment, the corresponding original confidence coefficient, the parking space position output by lossless filtering at the previous moment and the corresponding parking space confidence coefficient, updating and outputting the parking space position at the current moment, and updating the parking space confidence coefficient at the current moment. Compared with the prior art, frequent shaking of visual parking spaces and delay and distortion of parking space information updating are avoided, and the accuracy a
