An apparatus for detecting a usage status of a parking space, comprising:
- an image obtaining module configured for obtaining a monitored image of a to-be-detected parking space;
- a lane line position determining module configured for identifying lane line position information of the to-be-detected parking space from the monitored image;
- a vehicle position determining module configured for identifying vehicle information from the monitored image, wherein the vehicle information comprises vehicle position information;
- and
- a parking space status determining module configured for determining a usage status of the to-be-detected parking space based on a positional relationship between the lane line position information and the vehicle position information,
- wherein, the vehicle information further comprises license plate information;
- the parking space status determining module comprises:
- a first distance calculating sub-module configured for, if an intersection between a parking space range indicated by the lane line position information and a vehicle range indicated by the vehicle position information is larger than a preset parking threshold and a vehicle corresponding to the vehicle position information has a license plate, calculating a distance from a center of the license plate to a left parking space line of the to-be-detected parking space based on the lane line position information and the license plate information as a first left-parking-space-line distance, and calculating a distance from the center of the license plate to a right parking space line of the to-be-detected parking space based on the lane line position information and the license plate information as a first right-parking-space-line distance;
- a first intersection-line determining sub-module configured for determining whether the first left-parking-space-line distance, the first right-parking-space-line distance, and a width of the license plate meet a preset intersection-line condition;
- a first normal parking determining sub-module configured for, if the first left-parking-space-line distance, the first right-parking-space-line distance, and the width of the license plate do not meet the preset intersection-line condition, determining that the usage status of the to-be-detected parking space is that a vehicle is being parked normally in the to-be-detected parking space;
- and
- a first intersection-line parking determining sub-module configured for, if the first left-parking-space-line distance, the first right-parking-space-line distance, and the width of the license plate meet the preset intersection-line condition, determining that the usage status of the to-be-detected parking space is that a vehicle is being intersection-line parked in the to-be-detected parking space.
