Technical Field

[0001] This invention relates to the field of monitoring equipment technology, and in particular to a control method, device, electronic equipment, and storage medium for monitoring equipment. Background Technology

[0002] With the rapid development of various new energy vehicles, many high-end vehicles are equipped with onboard LiDAR (LiDAR for short) covering all directions of the vehicle body to assist driving, giving drivers a better driving experience. However, LiDAR has also brought some new problems.

[0003] In parking areas such as garages where various monitoring devices are deployed, some monitoring equipment without protective covers may have their photosensitive elements burned out or damaged if they are frequently directly irradiated by the pulsed laser beam emitted by the vehicle-mounted lidar. Summary of the Invention

[0004] This invention provides a control method, device, electronic device, and storage medium for monitoring equipment, which solves the defect in the prior art where monitoring equipment without protective plates is directly irradiated by pulsed laser beams emitted by vehicle-mounted lidar, thus burning and damaging the photosensitive elements in the monitoring equipment. By intelligently adjusting the first monitoring device in advance to turn towards the target direction that the lidar cannot irradiate from all monitoring devices in the parking area, the probability of the lidar burning and damaging the first monitoring device can be effectively reduced.

[0005] This invention provides a control method for a monitoring device, comprising the following steps.

[0006] The system receives vehicle information from a camera device installed at the entrance of the parking area. The vehicle information is captured by the camera device when it detects that the distance between the current vehicle and the entrance is less than a preset threshold.

[0007] The coverage area of ​​the lidar is determined based on the configuration information of the lidar corresponding to the vehicle information.

[0008] From all the monitoring devices in the parking area, identify the first monitoring device located within the coverage area.

[0009] The first monitoring device is controlled to turn towards the target direction that the lidar cannot directly hit.

[0010] According to a control method for a monitoring device provided by the present invention, the step of determining the coverage range of the lidar based on the configuration information of the lidar corresponding to the vehicle information includes: determining the vehicle model based on the vehicle information; determining the configuration of the lidar based on the trapezoidal protrusions on the exterior of the vehicle in the vehicle information; determining the configuration information based on the vehicle model and the configuration information; and determining the coverage range based on the planar model and the three-dimensional model corresponding to the configuration information.

[0011] According to a control method for a monitoring device provided by the present invention, determining a first monitoring device located within the coverage area from all monitoring devices in the parking area includes: determining a second distance between the current vehicle and each monitoring device among all the monitoring devices; determining the monitoring device corresponding to the second distance within the range of the lidar as the first monitoring device; and / or, determining the travel path of the current vehicle in the parking area according to the travel direction of the current vehicle; determining a target monitoring device located on the travel path from all monitoring devices in the parking area; and determining the first monitoring device located within the coverage area from the target monitoring device.

[0012] According to a control method for a monitoring device provided by the present invention, determining the vehicle model based on the vehicle information includes: determining the front information and / or vehicle identification of the current vehicle based on the vehicle information; and determining the vehicle model based on the preset vehicle information database if the front information and / or the vehicle identification matches the preset vehicle information database.

[0013] According to a control method for a monitoring device provided by the present invention, the method further includes: during the process of the current vehicle driving in the parking area, updating the first monitoring device in real time according to the current position of the current vehicle; if there is a first sub-monitoring device in the first monitoring device that moves out of the coverage area with the current position update, then controlling the first sub-monitoring device to photograph the current vehicle.

[0014] According to a control method for a monitoring device provided by the present invention, the method further includes: determining a second monitoring device located outside the coverage area from all the monitoring devices, and controlling the second monitoring device to photograph the current vehicle; updating the first monitoring device in real time according to the current position of the current vehicle while the current vehicle is driving in the parking area; if there is a second sub-monitoring device among the second monitoring devices that enters the coverage area with the current position update, controlling the second sub-monitoring device to photograph the target direction.

[0015] According to a control method for a monitoring device provided by the present invention, the method further includes: acquiring video footage of the current vehicle captured by all monitoring devices; and stitching together all the captured videos to obtain a continuous video recording of the current vehicle parked within the parking area.

[0016] The present invention also provides a control device for a monitoring device, comprising the following modules.

[0017] The transceiver module is used to receive vehicle information sent by a camera device installed at the entrance of the parking area. The vehicle information is captured by the camera device when it detects that the first distance between the current vehicle and the entrance is less than a preset threshold.

[0018] The processing module is used to determine the coverage area of ​​the LiDAR based on the configuration information of the LiDAR corresponding to the vehicle information; and to determine the first monitoring device located within the coverage area from all monitoring devices in the parking area.

[0019] The control module is used to control the first monitoring device to turn towards the target direction that the lidar cannot directly hit.

This method receives vehicle information from a camera installed at the entrance of a parking area. The vehicle information is captured by the camera when it detects that the distance between the current vehicle and the entrance is less than a preset threshold. Based on the configuration information of the lidar corresponding to the vehicle information, the coverage area of ​​the lidar is determined. From all monitoring devices within the parking area, a first monitoring device located within the coverage area is identified.

[0034] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0035] It should be noted that the control method for the monitoring equipment provided in this embodiment of the invention is applied to an electronic device. The electronic device is connected to a camera device, which is located at the entrance of the parking area. Optionally, the camera device is set at a height greater than a preset height threshold.

[0036] The electronic device can be a server, computer, controller, or any other device capable of processing and analyzing the received vehicle information.

[0037] The camera device is a high-position PTZ camera, which is typically used to monitor a large area and its surrounding environment. It can track or observe specific targets by rotating and tilting the lens. In this embodiment of the invention, the camera device is specifically used to monitor and identify vehicle information entering the parking area from a distance.

[0038] A parking area is a designated area for parking vehicles; it may be a parking lot, a garage, or any other place where vehicles are permitted to park.

[0039] The entrance refers to the point or passageway leading into the parking area.

[0040] Optionally, the preset height threshold can be set by the user based on the entrance height of the parking area. It is understandable that... Figure 1 This is a schematic diagram of a scene where a camera device is installed, as provided in an embodiment of the present invention. Figure 1 As shown, when a user sets up a camera at the entrance of a parking area, they need to know the preset height threshold first, and then install the camera at a position greater than the preset height threshold so that the camera can monitor and identify vehicle information entering the parking area from a distance.

[0041] The control method for the monitoring equipment provided in the embodiments of the present invention will be described in detail below.

[0042] Figure 2This is a flowchart illustrating the control method for the monitoring equipment provided in an embodiment of the present invention, as shown below. Figure 2 As shown, the method includes the following steps 201-204.

[0043] Step 201: Receive vehicle information sent by the camera device installed at the entrance of the parking area. The vehicle information is captured by the camera device when it detects that the first distance between the current vehicle and the entrance is less than a preset threshold.

[0044] Among them, vehicle information refers to information that can identify the vehicle.

[0045] Optionally, the preset threshold can be set before the camera device leaves the factory or it can be user-defined.

[0046] Since the camera can monitor and identify vehicle information entering the parking area from a distance, it can detect the first distance between the current vehicle and the entrance in real time. If the first distance is greater than or equal to a preset threshold, it means that the current vehicle is far from the camera. At this time, the camera can also obtain the vehicle information based on the real-time image. In addition, even if the current vehicle is equipped with a lidar, the pulsed laser beam emitted by the lidar cannot burn or damage the photosensitive element in the camera or the photosensitive element in the monitoring device in the parking area.

[0047] However, as the vehicle moves towards the parking area, the first distance detected by the camera gradually decreases. When this first distance falls below a preset threshold, it indicates that the vehicle is close to the camera and is about to enter the entrance. This could potentially damage the photosensitive elements in both the camera and the monitoring device caused by the pulsed laser beam. In this case, the camera then collects the vehicle's information and sends it to the electronic device. The electronic device receives the vehicle information from the camera to subsequently activate the monitoring devices within the parking area, preventing the pulsed laser beam from damaging the photosensitive elements of the monitoring devices.

[0048] LiDAR, also known as vehicle-mounted LiDAR, is mainly used to assist in laser scanning and triangulation of the vehicle. The laser transmitter in this LiDAR emits pulsed laser beams, forming a fan-shaped pattern. Furthermore, the laser receiver receives the returned laser signals to calculate the distance between the vehicle and external objects.

[0049] The photosensitive element is the core component of the camera in monitoring and video recording devices, mainly responsible for converting light into electrical signals, and then forming video signal output to realize the shooting / recording of the current vehicle.

[0050] There is at least one monitoring device in the parking area, and each monitoring device is a bullet camera used to photograph / record the current vehicle.

[0051] Optionally, each camera in the bolt-action configuration needs to be equipped with a rotatable bracket, which is used to support the corresponding camera in the bolt-action configuration to rotate freely in multiple directions and adjust the angle.

[0052] Optionally, if the first distance is less than a preset threshold, the method may further include: the electronic device controlling the camera to turn towards the target direction that the lidar cannot directly hit.

[0053] If the distance is less than a preset threshold, it indicates that the vehicle is too close to the camera device, and the pulsed laser beam emitted by the lidar may burn or damage the photosensitive element in the camera device. In this case, the electronic device intelligently controls the camera device to rotate and turn towards the target direction (e.g., upwards). This effectively reduces the damage to the photosensitive element caused by the pulsed laser beam, thereby improving the safety of the imaging device and ensuring its normal operation.

[0054] Optionally, the vehicle information is determined by the camera device based on the following steps: the camera device determines that the current vehicle is moving towards the entrance based on the current vehicle's turn signal, the direction of the vehicle's front offset, and the direction of the route travel, and collects vehicle information based on the driving results.

[0055] Turn signals are a type of indicator device in a vehicle, typically installed at the front and rear of the vehicle.

[0056] The direction of vehicle front offset refers to the change in angle of the front of the vehicle relative to its straight-line direction of travel.

[0057] The direction of travel refers to the overall direction of the road or route that the vehicle is currently traveling on.

[0058] As the vehicle is in motion, its turn signals, direction of deviation, and route direction will change in real time. At this time, the camera device can collect parameters such as the vehicle's turn signals, direction of deviation, and route direction in real time. Based on these parameters, if it is determined that the vehicle is moving towards the entrance, the camera device can collect vehicle information based on the driving results.

[0059] Step 202: Determine the coverage area of ​​the LiDAR based on the configuration information of the LiDAR corresponding to the vehicle information.

[0060] The configuration information refers to the specific parameter information of the lidar in the current vehicle.

[0061] Coverage range typically refers to the area or space where lidar can effectively measure distances and conduct detection.

[0062] Optionally, the coverage area can be the lidar coverage area at the rear of the vehicle or the lidar coverage area at the top of the vehicle.

[0063] After acquiring vehicle information, the electronic equipment can analyze the vehicle information to obtain the configuration information of the light radar, and then analyze the configuration information to obtain the coverage range, providing data support for the subsequent control and monitoring of the steering of the device.

[0064] In some embodiments, the electronic device determines the coverage area of ​​the LiDAR based on the configuration information of the LiDAR corresponding to the vehicle information. This may include: the electronic device determining the vehicle model based on the vehicle information; the electronic device determining the configuration of the LiDAR based on the trapezoidal protrusions on the exterior of the vehicle in the vehicle information; the electronic device determining the configuration information based on the vehicle model and configuration information; and the electronic device determining the coverage area based on the planar model and three-dimensional model corresponding to the configuration information.

[0065] The vehicle model is a unique identifier assigned by a vehicle manufacturer to each model it produces. This identifier typically includes the type of the vehicle (such as a sedan, truck, or sport utility vehicle (SUV), manufacturer information, and specific model and year details).

[0066] The exterior of a vehicle refers to its external structure, including the front, top, and rear.

[0067] A trapezoidal protrusion typically refers to a specific feature on the exterior of a vehicle, particularly when related to LiDAR (Light Detection and Ranging) configurations. Optionally, trapezoidal protrusions may include the type, location, and number of LiDAR units.

[0068] The configuration of a lidar system refers to its specific arrangement on the vehicle, including its type (e.g., mechanical, solid-state), quantity, installation location, and scanning range. This information is crucial for determining the coverage area.

[0069] A planar model is a simplified representation used to describe the coverage area of ​​a lidar system on a two-dimensional plane. It is typically calculated based on parameters such as the lidar's scanning range and angular resolution.

[0070] A 3D model is a complex representation used to describe the coverage area of ​​a lidar system in three-dimensional space. It is typically calculated based on parameters such as the lidar's ranging capability, field of view, and scanning speed. This 3D model can more accurately reflect the lidar's coverage capability in a real-world environment.

[0071] After acquiring vehicle information, the electronic device can analyze and judge the vehicle information by linking with big data in the network to obtain the vehicle model. Simultaneously, it can determine and analyze the trapezoidal protrusions on the vehicle's exterior (such as the top). During the analysis, if the trapezoidal protrusions are determined not to exist, it means the vehicle does not have a LiDAR. If trapezoidal protrusions are determined, the configuration of the LiDAR can be accurately determined based on the protrusion details (such as the type, location, and number of LiDARs), and whether the vehicle model is a high-end model. The electronic device then combines the vehicle model and configuration information to determine the specific parameter information (i.e., configuration information) of the LiDAR in the vehicle from a pre-set vehicle manufacturer network. Further, the electronic device analyzes this configuration information to obtain the planar coverage range and the height coverage range. Based on the planar model corresponding to the planar coverage range and the 3D model corresponding to the height coverage range, a highly accurate coverage range is constructed.

[0072] For example, Figure 3a This is a schematic diagram of the planar model corresponding to the planar coverage area provided in the embodiment of the present invention; Figure 3b This is a schematic diagram of the structure of a three-dimensional model corresponding to the height coverage area provided in an embodiment of the present invention. By combining planar and three-dimensional models, the electronic device can construct a coverage area with high accuracy.

[0073] In some embodiments, the electronic device determines the vehicle model based on vehicle information, which may include: the electronic device determining the front information and / or vehicle identification of the current vehicle based on the vehicle information; and if the front information and / or vehicle identification matches a preset vehicle information database, the electronic device determines the vehicle model based on the preset vehicle information database.

[0074] The term "front-end information" typically refers to the vehicle's exterior features, particularly the front section, which can be used to distinguish different models or brands of vehicles. Optionally, front-end information may include: the vehicle's shape and size, the shape and position of the headlights, the bumper design, and the grille style.

[0075] Vehicle identification is information used to uniquely identify a vehicle. The most common vehicle identification is the license plate number, but it may also include the Vehicle Identification Number (VIN), the vehicle manufacturer's serial number, or other vehicle manufacturer-specific identifiers.

[0076] The default vehicle information database is a database containing a large number of vehicle models, a large amount of vehicle front information, and a large amount of vehicle identification information.

[0077] In the process of determining the vehicle model based on vehicle information within a large network, electronic devices can first analyze the vehicle information to obtain the vehicle's front information and / or vehicle identification. Then, the front information and / or vehicle identification are matched with a preset vehicle information database. If the match fails, it means that the current vehicle and its related information (such as vehicle model) do not exist in the preset vehicle information database. If the match succeeds, it means that the relevant information of the current vehicle exists in the preset vehicle information database, and the vehicle model can be directly retrieved from the preset vehicle information database.

[0078] Step 203: Identify the first monitoring device within the coverage area from all monitoring devices in the parking area.

[0079] The number of first monitoring devices is at least one.

[0080] When a vehicle enters a parking area, the electronic equipment can analyze all the monitoring devices in the parking area and identify the first monitoring device within its coverage area for subsequent steering control.

[0081] Optionally, all monitoring devices within the parking area can be determined by analyzing a pre-set parking area monitoring deployment map using electronic equipment. Understandably, after identifying all monitoring devices, the electronic equipment can accurately determine the monitoring status of each monitoring point.

[0082] Among them, the pre-set parking area monitoring deployment engineering survey map is an engineering survey drawing that details the planning and display of the deployment of parking area monitoring equipment.

[0083] For example, Figure 3c This is a schematic diagram of a pre-set parking area monitoring deployment site survey provided in an embodiment of the present invention. For example... Figure 3c As shown, based on the preset parking area monitoring deployment survey map, the electronic equipment can clearly understand the internal scene map and monitoring point map of the parking area, and thus know the relevant range that the monitoring device at each monitoring point can monitor.

[0084] In some embodiments, the electronic device determines the first monitoring device within its coverage area from all monitoring devices within the parking area, which may include at least one of the following implementations: Implementation Method 1: The electronic device determines the second distance between the current vehicle and each monitoring device in the total number of monitoring devices; the electronic device identifies the monitoring device corresponding to the second distance within the range of the lidar as the first monitoring device.

[0085] In determining the first monitoring device, the electronic device first determines the second distance between each monitoring device and the current vehicle; that is, the electronic device acquires as many second distances as there are monitoring devices. Then, the electronic device compares each of these second distances with the coverage area and identifies the monitoring device corresponding to the second distance within the range of the lidar as the first monitoring device. At this time, the electronic device can also identify the monitoring device corresponding to the second distance outside the range of the lidar as the second monitoring device.

[0086] It should be noted that after identifying the first monitoring device and the second monitoring device, the electronic device can combine the first monitoring device, the second monitoring device and the current vehicle to construct a vehicle-radar model. In this way, the electronic device can intelligently control the first monitoring device and the second monitoring device to rotate the camera based on the vehicle-radar model.

[0087] Implementation Method 2: The electronic device determines the current vehicle's travel path within the parking area based on the current vehicle's direction of travel; the electronic device identifies the target monitoring device on the travel path from all monitoring devices within the parking area; and the electronic device identifies the first monitoring device within the coverage area from the target monitoring devices.

[0088] For example, Figure 3d This is a schematic diagram of a scenario where all monitoring devices are linked and controlled according to an embodiment of the present invention. Figure 3d As shown, when only one vehicle is currently driving within the parking area, the electronic equipment can control all monitoring devices in a coordinated manner. Specifically, when the vehicle enters a side road entrance (e.g., the entrance itself), the electronic equipment controls several monitoring devices closest to that entrance to adjust their monitoring angles, focusing on the entrance direction to record the vehicle's movement and determine its direction of travel in real time. Based on this direction, it then determines the vehicle's path and non-path within the parking area. Next, the electronic equipment identifies target monitoring devices along the path and other target monitoring devices outside the path from all the monitoring devices within the parking area. Using these target monitoring devices as a basis, the electronic equipment then identifies the first monitoring device within its coverage area. At this point, the electronic equipment can also identify other monitoring devices outside the coverage area. Based on this, the electronic equipment controls the first target monitoring device to photograph the vehicle and controls the second target monitoring device to return to its initial state.

[0089] Optionally, the monitoring devices closest to the branch entrance refer to the monitoring devices being all less than a first preset distance from the branch entrance. This first preset distance can be set by the electronic devices before they leave the factory or can be user-defined.

[0090] It should be noted that before the vehicle enters each branch road entrance, the nearest monitoring devices at the corresponding branch road entrance will follow the above algorithm control logic. First, focus on the branch road entrance. After determining the current vehicle's direction of travel, control the monitoring devices in the non-traveling direction (i.e., the second target monitoring devices) to restore their original monitoring areas, and control the monitoring devices in the traveling direction (i.e., the first target monitoring devices) to continue monitoring.

[0091] For example, Figure 3e This is a schematic diagram of a scenario where all monitoring devices are linked and controlled according to an embodiment of the present invention. Figure 3e As shown, when multiple vehicles are driving in the parking area, the electronic equipment can control all monitoring devices in a coordinated manner. Specifically, when the electronic equipment determines the current vehicle's travel path, it adopts the principle of proximity dispatch. If there are other vehicles on the travel path, it will simultaneously dispatch several monitoring devices (such as three monitoring devices) that are close to the other vehicles to monitor the other vehicles. Meanwhile, the monitoring devices closest to the entrance of the branch road will still monitor the current vehicle at the entrance of the branch road.

[0092] Optionally, the number of monitoring devices at a distance from other vehicles refers to the distance between these monitoring devices and other vehicles being less than a second preset distance. This second preset distance can be set before the electronic devices leave the factory or it can be user-defined.

[0093] In summary, Figure 3c and Figure 3e During the process of controlling all monitoring devices in a coordinated manner, the electronic equipment can intelligently coordinate multiple monitoring devices to monitor the travel routes of LiDAR vehicles and vehicles without LiDAR, and can also protect monitoring devices without protective plates.

[0094] Step 204: Control the first monitoring device to turn towards the target direction that the lidar cannot directly hit.

[0095] While the electronic device is controlling the monitoring device in the direction of travel (i.e., the first target monitoring device), it can, after identifying the first monitoring device among the target monitoring devices, control the lens of the first monitoring device to turn towards the target direction, which is within the range that the lidar cannot directly hit. In this way, the electronic device can intelligently adjust the first monitoring device in advance when the lidar passes by, which can effectively reduce the probability of the lidar burning out or damaging the first monitoring device.

[0096] In some embodiments, the method may further include at least one of the following implementations.

[0097] Implementation Method 1: While the vehicle is driving within the parking area, the first monitoring device is updated in real time based on the vehicle's current location; if there is a first sub-monitoring device that moves out of the coverage area as the current location is updated, the first sub-monitoring device is controlled to photograph the vehicle.

[0098] The number of first sub-monitoring devices is at least one.

[0099] As the vehicle moves within the parking area, the first monitoring device within its coverage area changes in real time as the vehicle's position changes. Based on this, the electronic equipment can update the first monitoring device in real time according to the vehicle's current position. If a first sub-monitoring device moves out of the coverage area as the vehicle's position changes, it means that the first sub-monitoring device is not part of the first monitoring device. In this case, since the pulsed laser beam emitted by the lidar cannot burn or damage the photosensitive element in the first sub-monitoring device, the first sub-monitoring device can be directly controlled to take a picture of the vehicle.

[0100] Implementation Method 2: The electronic device identifies the second monitoring device located outside the coverage area from all monitoring devices and controls the second monitoring device to photograph the current vehicle; while the current vehicle is driving in the parking area, the first monitoring device is updated in real time according to the current position of the current vehicle; if there is a second sub-monitoring device in the second monitoring device that enters the coverage area with the current position update, the second sub-monitoring device is controlled to photograph the target direction.

[0101] The number of second sub-monitoring devices is at least one.

[0102] The electronic device, while identifying the first monitoring device within its coverage area from all monitoring devices, can also identify a second monitoring device outside that coverage area. Since the pulsed laser beam emitted by the lidar cannot burn or damage the photosensitive element in the second monitoring device, it can directly control the second monitoring device to photograph the current vehicle. As the vehicle's position changes, both the first and second monitoring devices within and outside the coverage area change in real time. Based on this, the electronic device can first update the first and second monitoring devices in real time according to the vehicle's current position. If a second sub-monitoring device appears within the coverage area as the vehicle's position changes, it is considered a first monitoring device. In this case, since the pulsed laser beam emitted by the lidar may burn or damage the photosensitive element in the second sub-monitoring device, it is necessary to control the second sub-monitoring device to turn towards the target. The entire process can intelligently coordinate with surrounding area monitoring for avoidance, while distant monitoring devices will focus on monitoring, effectively reducing the probability of the lidar burning or damaging the second sub-monitoring device.

[0103] Implementation method 3: The electronic device acquires the video footage of the current vehicle captured by all monitoring devices; the electronic device stitches together all the captured videos to obtain a continuous recording of the current vehicle parked in the parking area.

[0104] When a vehicle is parked in the target parking space within the parking area, the electronic equipment can acquire video footage of the vehicle from all monitoring devices. This footage is then stitched together to create a smooth transition between video recordings, resulting in a continuous video of the current vehicle. There are no obvious jumps or splices between monitoring devices, effectively reducing the probability of lost video footage. This process also reduces the likelihood of the LiDAR directly shining on the nearest monitoring device, which could damage the photosensitive elements of the parking lot's monitoring equipment. Furthermore, it tracks the vehicle's route and movement in real time.

[0105] It should be noted that when multiple vehicles are traveling on the same path, the electronic equipment can control all monitoring devices in the following situations.

[0106] Scenario 1: When multiple vehicles are traveling in the same direction, the electronic equipment can determine whether the monitoring device at the rear of the current vehicle is still within the coverage range after the first monitoring device rotates the target angle (e.g., 180 degrees) (the coverage range of the rear lidar of some vehicles is smaller than that of the top lidar). If it is not within the coverage range of the rear lidar, all relevant cameras (except for the monitoring device at the end of the travel path) will rotate the target angle to record and track the vehicle's movement in the direction of the rear.

[0107] Scenario 2: If two adjacent coverage areas simultaneously have oncoming vehicles, both surveillance cameras must avoid them. In this case, the two surrounding surveillance devices (such as the third and fourth surveillance devices) on the same travel path will be activated to focus on the vehicle. If the surrounding surveillance devices also have radar vehicles that need to be avoided, the nearest surveillance devices on the two surrounding side roads will be activated to focus on the travel path to monitor the vehicle. The vehicle will be tracked based on its initial start-up status and travel path prediction, combined with side recordings from the surrounding side roads.

[0108] Scenario 3: Extreme Situation. If the traffic flow in the parking area is extremely high, there may be situations where all monitoring devices are within the coverage area of ​​the LiDAR vehicles, and all monitoring devices must avoid this area. In this case, it is necessary to assess the possibility of installing telephoto lens cameras at the top of each road segment (these cameras are normally inactive as they cannot be covered by the LiDAR). If it is determined that the surrounding monitoring devices cannot be focused, then the telephoto lens camera at the corresponding road segment should be activated to monitor the entire scene and ensure complete video recording of vehicles.

[0109] In this embodiment of the invention, vehicle information sent by a camera device located at the entrance of the parking area is received. This vehicle information is captured by the camera device when it detects that the distance between the current vehicle and the entrance is less than a preset threshold. Based on the configuration information of the lidar corresponding to the vehicle information, the coverage area of ​​the lidar is determined. From all monitoring devices within the parking area, a first monitoring device located within the coverage area is identified. The first monitoring device is then controlled to turn towards a target direction that the lidar cannot directly illuminate. This method, by intelligently adjusting the first monitoring device to turn towards a target direction that the lidar cannot illuminate when the first monitoring device within the lidar's coverage area is identified from all monitoring devices within the parking area, can effectively reduce the probability of the lidar burning out or damaging the first monitoring device.
