[0044] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0045] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.

[0046] This embodiment relates to a parking lot entrance and exit monitoring system. Figure 1-Figure 9As shown, it includes a barrier gate device 1, a second image acquisition device 2 and a control device 3, wherein the barrier gate device 1 and the second image acquisition device 2 arranged near the barrier gate device 1, and the control device 3 respectively connected to the barrier gate device 1 and the second image acquisition device 2 in communication;

[0047] The barrier device 1 comprises a first image acquisition device 101, which is used to acquire the front license plate information of the oncoming vehicle;

[0048] The second image acquisition device 2 is arranged near the gate device 1 which is higher than the first image acquisition device 101, and is used to acquire the rear license plate information of the approaching vehicle;

[0049] The control device 3 is used to receive the front license plate information and the rear license plate information to determine whether they are the same vehicle. Optionally, the control device 3 can be connected to the first image acquisition device 101 and the second image acquisition device 2 through a wired or wireless connection communication method, wherein the wired communication connection method can be an Ethernet cable connection or a USB connection, and the wireless connection communication method can be a Bluetooth connection or a mobile communication connection. Furthermore, when the vehicle enters or leaves the parking lot, the utility model can first collect the front license plate information through the first image acquisition device 101, and collect the rear license plate information of the oncoming vehicle through the second image acquisition device 2. The front license plate information collected by the first image acquisition device 101 and the rear license plate information collected by the second image acquisition device 2 will be transmitted to the control device 3. The control device 3 is used to determine whether they are the same vehicle. When the rear vehicle is close to the front vehicle, the first image acquisition device 101 will not be able to collect information on the front license plate of the rear vehicle. Since the second image acquisition device 2 is higher than the first image acquisition device 101, If there is a vehicle closely following the rear of the rear vehicle, the second image acquisition device 2 can also collect the rear license plate information of the rear vehicle at a higher height. At this time, the control device 3 detects that the second image acquisition device 2 has collected information on the rear license plate of the rear vehicle, and the first image acquisition device 101 has not collected the front license plate information of the rear vehicle, then the control device 3 determines that the rear vehicle is following the vehicle in and out of the site, and the control device 3 reports the license plate to the front-end software to form a record. The control device 3 has a built-in processor and memory. By receiving the front license plate information of the target vehicle collected by the first image acquisition device 101 and the rear license plate information of the target vehicle collected by the second image acquisition device 2, the processor runs the currently widely used image recognition algorithm to determine the vehicle head information and parking space information, as well as the corresponding front license plate information and rear license plate information, and then uses the license plate information matching method to determine whether the front license plate information and the rear license plate information are the same vehicle.

[0050] In this embodiment, the second image acquisition device 2 is disposed on any side of the interception channel of the barrier device 1 and is located at a first preset distance in front of the barrier device 1 in the driving direction; or,

[0051] The second image acquisition device 2 is arranged on any side of the interception channel of the barrier device 1 and is located at a second preset distance behind the barrier device 1 in the driving direction.

[0052] The second image acquisition device 2 is disposed above the interception channel of the barrier device 1 and is located at a third preset distance in front of the barrier device 1 in the driving direction; or,

[0053] The second image acquisition device 2 is disposed above the interception channel of the barrier device 1 and is located at a fourth preset distance behind the barrier device 1 in the driving direction.

[0054] It is understandable that the first preset distance, the second preset distance, the third preset distance and the fourth preset distance can be changed according to the actual application scenario. For example, the first preset distance, the second preset distance, the third preset distance and the fourth preset distance can all be 0.5 meters, 1 meter, 2 meters and 3 meters, etc. Further, the distance can be set according to the parking type or quasi-parking type of the parking lot, for example, the length of the longest parking space in the parking lot + 0.5 meters or the length of the quasi-parking type of the parking lot + 0.5, etc. When the entrance and exit of the parking lot is set in an open-air area, the second image acquisition device 2 can be set above the passage in the form of a gantry. When the entrance and exit of the parking lot is set in an underground area, the second image acquisition device 2 can be fixed on the top surface above the lane.

[0055] In this embodiment, the first image acquisition device 101 includes: a first image acquisition lens,

[0056] The second image acquisition device 2 comprises: a second image acquisition lens;

[0057] The image acquisition direction of the first image acquisition lens is opposite to that of the second image acquisition lens. Furthermore, the image acquisition end of the first image acquisition head faces the entrance end of the parking lot or the exit end of the parking lot, and the image acquisition end of the second image acquisition head faces away from the entrance end of the parking lot or the exit end of the parking lot.

[0058] See also Figure 8 and Fig. 9 , this embodiment further includes a motion component 4, the motion component 4 includes a lifting mechanism 401 and a rotating mechanism 402 provided at the lifting end of the lifting mechanism 401;

[0059] The second image acquisition device 2 is fixedly arranged on a side of the rotating mechanism 402 away from the lifting mechanism 401. Optionally, the lifting mechanism 401 may be an electric lifting rod or a hydraulic lifting rod, and the rotating mechanism 402 may be a turntable that rotates relative to the top damping of the lifting mechanism 401, or a rotating motor is arranged on the top of the lifting mechanism 401 and a turntable is arranged at the output end of the rotating motor, and the turntable is driven to rotate by the rotating motor.

[0060] In this embodiment, the first image acquisition device 101 and the second image acquisition device 2 include: any one of an infrared image acquisition device, a night vision image acquisition device and a full-color image acquisition device.

[0061] In this embodiment, the control device 3 also includes an alarm device, which is used to mark the vehicle information corresponding to the rear license plate information with a warning mark when the current license plate information and the rear license plate information are not the same vehicle. Optionally, the alarm device can also emit a prompt sound to remind surrounding staff that a vehicle is following the vehicle into or out of the parking lot.

[0062] See also Figure 1 This embodiment also includes a storage device 5, which is communicatively connected to the barrier device 1 and the control device 3, and is used to store the front license plate information and the corresponding vehicle information, as well as the rear license plate information and the vehicle information corresponding to the warning mark.

[0063] In this embodiment, the second image acquisition device 2 and the control device 3 are arranged in the same protective device, and the protective device can be a hollow shell, and the shell can be made of plastic or steel alloy. It can be understood that the control device 3 can also be arranged separately, or in some cases, the control machine of the gate device can also be used as the control device 3 in this application.

[0064] See also Figure 2-Figure 8 , this embodiment further includes a sensing device 6, which is arranged at a fifth preset distance behind the gate in the driving direction;

[0065] The sensing device 6 is communicatively connected with the second image acquisition device 2 and the barrier device 1, and is used to wake up the second image acquisition device 2 and the barrier device 1 when sensing an incoming vehicle. Furthermore, the sensing device 6 includes a first sensing component 601 and a second sensing component 602. Optionally, the fifth preset distance can be set to 0.5 meters, 1 meter, 2 meters, and 3 meters, etc. according to the actual application scenario. The first sensing component 601 and the second sensing component 602 can be any two of a ground sensing device, an infrared sensor, an ultrasonic sensor, and a microwave radar sensor. The first sensing component 601 and the second sensing component 602 cooperate to sense whether the vehicle is in place.

[0066] The working principle of the utility model is roughly as follows: when a vehicle enters or leaves a parking lot, the utility model firstly collects the information of the front license plate through the first image acquisition device 101, and collects the information of the rear license plate of the oncoming vehicle through the second image acquisition device 2. The front license plate information collected by the first image acquisition device 101 and the rear license plate information collected by the second image acquisition device 2 are transmitted to the control device 3, and the control device 3 is used to determine whether they are the same vehicle. When the rear vehicle is close to the front vehicle, the first image acquisition device 101 will not be able to collect information on the front license plate of the rear vehicle. Since the second image acquisition device 2 is higher than the first image acquisition device 101, even if there is another vehicle close to the rear of the rear vehicle, the second image acquisition device 2 is at a higher height and can collect the rear license plate information of the rear vehicle. At this time, the control device 3 detects that the second image acquisition device 2 has collected information on the rear license plate of the rear vehicle, and the first image acquisition device 101 has not collected the front license plate information of the rear vehicle, then it is determined that the rear vehicle is following the vehicle in and out of the lot, and the control device 3 will report the license plate to the front-end software to form a record.

[0067] The above is only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
