And (1.2) carrying out outline extraction on the collected image, and extracting a license plate image which is matched with a preset rectangular frame. The preset rectangular frame is actually a fixed shape of the license plate, generally, the aspect ratio of the rectangle is determined, and meanwhile, when the outline is extracted, the parking distance of the electric vehicle should be considered, that is, the size of the license plate image is obtained according to the size of the vehicle.
And (1.3) recognizing the character information in the license plate images, and performing superposition comparison on the character information of the license plate images of the two collected images to obtain a string of repeated characters serving as the license plate information of the electric vehicle.
In some embodiments, the acquisition method may further include the following steps.
(1.4) please refer to fig. 2, the ultrasonic waves are transmitted to the electric automobile in the occupied parking space and the time is synchronously counted. Because the ultrasonic waves are reflected after being transmitted to the chassis of the vehicle and the propagation speed of the ultrasonic waves in the air is constant, the corresponding propagation distance can be calculated, and further the ground clearance can be calculated. In this embodiment, the timing time is the time interval from the time the ultrasonic detection module transmits the ultrasonic wave from its transmitter to the time the vehicle receives the same ultrasonic wave by the receiver, the transmitter and the receiver being located in the same vertical direction of the chassis of the vehicle.
(1.5) referring to fig. 3, calculating the ground clearance of the vehicle from the ground of the corresponding parking space according to the timing time; the formula for calculating the height above the ground is:
wherein, H is the height from the ground, C is the ultrasonic wave propagation speed, T is the timing time, and D is the distance between the transmitting end and the receiving end of the ultrasonic equipment. The propagation speed of the ultrasonic wave is not so great, and is generally 340m/s in air at 15 ℃. Of course, the propagation speed of the ultrasonic wave is positively correlated with the temperature, and the correlated parameters can be set in the actual calculation process. However, since the temperature change is not large in a short time, particularly, during the single timing of the ultrasonic wave, the propagation speed can be considered to be a constant value, which does not excessively affect the accuracy of the ground clearance in the present embodiment. In practice, the value of distance D is very small relative to CT, and in some embodiments, the value of distance D may be taken to be zero. Therefore, the formula for calculating the height above ground can be simplified as:
and (1.6) judging whether the change value of the ground clearance is larger than a preset height difference. The preset height difference can be based on the height deviation caused by that a single person leaves the electric automobile after the electric automobile is parked.
And (1.7) when the change value is larger than the preset height difference, determining that the driver gets off the electric automobile and using the vehicle-mounted information as vehicle information. The vehicle-mounted information provides a precondition for subsequent scheduling work, and the operation and maintenance platform can conveniently hold the position information of the driver.
