Abstract: A method for automatically recording and transmitting a parking space number, includes judging whether vehicle speed information is lower than a preset value. When it is confirmed that the vehicle speed information is lower than the preset value, a part of vehicle surrounding images of multiple vehicle surrounding images is obtained according to gear position information of the vehicle. A parking space recognition model is established according to the multiple vehicle surrounding images and recognizing multiple characters corresponding to the part of the vehicle surrounding images. The multiple characters are grouped to form multiple sets of parking space numbers corresponding to the part of the vehicle surrounding images. A priority of the multiple sets of parking space numbers is then determined. After the vehicle is turned off, the parking space number with the highest priority in the multiple sets of parking space numbers is transmitted to a user terminal.
