The ball machine tracks the target non-motor vehicle by rotating the first cloud platform, the corresponding relation between the movement speed of the non-motor vehicle and the rotation speed of the cloud platform is preset in the control equipment, and the target rotation speed of the first cloud platform can be determined according to the target movement speed of the target non-motor vehicle and the corresponding relation.

According to the target rotating speed and formula

When tracking a long-distance target, the pan-tilt velocity V₁Is smaller than the tripod head V_maxThe current thus obtainedIs also less than the original driving current I_maxThereby reducing system power consumption.

The violation detection scheme provided by the embodiment of the invention is explained in detail below with reference to the attached drawings.

The violation detection system mainly comprises: the system comprises a panoramic camera (rifle bolt), a cradle head 1 (second cradle head), a detail camera (ball machine), a cradle head 2 (first cradle head), an electronic tag (RFID) card reader, a cradle head 3 (third cradle head) and control equipment, wherein the control equipment can be equipment such as a tablet personal computer and a server. The schematic diagram of the system functional module is shown in fig. 6, the control device can be arranged in an upper cavity of the dome camera and is respectively connected with a holder 1 and a holder 2, the holder 1 is connected with the PTZ panoramic camera, and the PTZ panoramic camera comprises a wide-angle lens and an image Sensor-1. The holder 2 is connected with an RFID card reader which comprises an RFID receiver. The control equipment is also connected with a detail PTZ dome camera part, and the detail PTZ dome camera part comprises a detail zoom lens, an image Sensor-2, a holder 2 and an independent intelligent main control.

The panoramic camera is used for identifying and monitoring non-motor vehicle targets in a large-range scene, and is linked with the detail camera to perform tracking focusing and snapshot according to intelligent events (triggering violation detection rules). The detail camera is carried on the cloud platform 2 and mainly responsible for tracking the target, and the details of the target are captured to acquire more accurate and clear image information. The components of the pan-tilt 1 and the pan-tilt 2 are independent of each other, and the movement of the pan-tilt 1 does not cause the monitoring visual field of the detail camera to change. The RFID card reader is carried on the holder 3 and is responsible for detecting the electronic tags of the non-motor vehicles in the current coverage range, reading license plate information, vehicle owner identity information and the like stored in the electronic tags in advance and used for accurate identity matching of the non-motor vehicles and people. The control equipment can acquire target object distance information measured by the detail camera in real time, and the power of the RFID card reader can be adjusted according to the change of the target object distance. The principle of the detail camera providing object distance information is that for different object distances there will be different object distance curves, i.e. a zoom following curve as shown in fig. 7, along which direction the lens is clear throughout. It is represented by a pair of Zoom (step number of Zoom motor) and Focus (step number of Zoom motor) combinations, and the combined curve represents an object distance. And obtaining object distance value information according to the combination result of Zoom and Focus. In fig. 7, the abscissa is the number of steps of the zoom motor, the ordinate is the number of steps of the zoom motor, INF denotes infinity, and M denotes a distance unit meter.

Based on the description of the system device, in order to solve the problem of accurate matching of the identity of a person and a vehicle when a non-motor vehicle peccancy is obtained in a complex environment, reduce the probability of missed detection caused by loss of an edge target and simultaneously reduce the power consumption of the whole system, the embodiment of the invention provides a low-power consumption non-motor vehicle peccancy detection method for dynamically realizing the combination of gun-ball linkage and an RFID technology, and the core idea is as follows:

the panoramic camera is used for monitoring a large-range scene, when a non-motor vehicle violation event occurs, the panoramic camera is linked with the detail camera to track, focus and snapshot a target non-motor vehicle, and simultaneously the RFID card reader carried by the holder 3 is controlled to dynamically adjust the position and the transmitting power so as to adjust the detection range of the target non-motor vehicle, so that the target is ensured to be in the detection range of the RFID card reader when the target is tracked remotely, the missing detection caused by the target loss is prevented, and the limitation that the prior art can only detect in a limited range is overcome. And the strategy of synchronously adjusting the driving current of the holder is introduced to achieve the effect of reducing the power consumption of the whole system; when the target is tracked in a close range, the transmitting power of the RFID card reader can be adjusted to be reduced, and the full-power operation time is reduced, so that the system power consumption of the high-frequency module of the RFID card reader is reduced.

Fig. 8 is a schematic view of a violation detection flow provided by the embodiment of the present invention, as shown in fig. 8, the specific steps are described as follows:

step 1: initializing the system, initializing parameters of each device in the system, and obtaining parameters of the RFID card reader carried by the pan/tilt head 3, such as the coverage of the RFID card reader capable of identifying the electronic tag, the current working power of the RFID card reader module, and the like.

Step 2: and intelligent configuration, wherein the panoramic camera intelligently monitors in a large range, extracts target non-motor vehicles and the like in the visual field, and configures intelligent detection rules of the panoramic camera, such as rule violations and the like.

And step 3: and obtaining the target object distance and speed, determining the target object distance of the target non-motor vehicle by the detail camera, and calculating the movement speed and the like according to the target object distance variation in unit time.

And 4, step 4: selecting a working mode, determining the working mode according to the target object distance obtained by the detail camera, comparing the working mode with the maximum value of the range capability covered by the electromagnetic field of the RFID card reader, and only carrying out common video monitoring by the panoramic camera when the target does not enter the range covered by the RFID card reader and no violation event occurs, thereby avoiding unnecessary system resource consumption; and when the target enters the coverage range of the RFID card reader, the RFID card reader acquires and records the information carried in the radio frequency signal sent by the electronic tag of the target non-motor vehicle, and then waits for the triggering of the violation event.

And 5: the RFID card reader acquires information according to intelligent event linkage, and when a violation event occurs, such as a non-motor vehicle running a red light, the panoramic camera is linked with the detail camera and controls the pan-tilt 2 to move, so that active tracking snapshot of the violation target non-motor vehicle is completed, and high-quality image evidence is acquired. At the moment, the target non-motor vehicle is in the magnetic field coverage range of the RFID card reader, and the RFID card reader acquires and records the real-time information of the violation target electronic tag. And the evidence obtaining of the violation behaviors is realized through the accurate matching of the video snapshot and the identity of the electronic tag. It should be noted that, when the panoramic camera is linked with the detail camera to track the target, the RFID card reader is synchronously controlled, and the RFID card reader adjusts the coverage by rotating the pan-tilt 3, so that the coverage of the magnetic field is wider, the limitation that the prior art can only monitor in a fixed range is overcome, the RFID card reader and the target electronic tag can keep a relative optimal receiving position, and the probability of missed detection is reduced.

Step 6: and adjusting the power of the RFID card reader, acquiring object distance information, motion speed and the like measured by the detail camera by the RFID card reader, and judging whether the target non-motor vehicle is far away from or close to the RFID card reader according to the acquired object distance information. If the target is far away, the cradle head 3 is rotated according to the moving direction of the target position, the coverage range of the RFID card reader is adjusted along the target far away direction, and meanwhile, the power increase of the RFID card reader is dynamically adjusted, so that the RFID card reader can receive information returned by the target, and the remote target tracking also has a good identity precise matching effect; if the target approaches, the transmitting power of the RFID card reader is reduced, the power consumption of the system is reduced while the target is tracked, and system resources are saved. When the target exceeds the maximum range or the target evidence collection is finished, the tracking is finished, and the tracking of the next target is started, so that the occurrence of missing detection is reduced to the maximum extent.

In addition, in step 6, in order to balance the violation detection effect of the long-distance target and the power consumption of the system and further reduce the power consumption of the whole working process, the embodiment of the invention provides a strategy for synchronously adjusting the transmitting power of the RFID card reader and the driving current of the holder motor, which comprises the following steps: namely, the driving current of the motor is reduced while the transmitting power of the RFID card reader is increased in the long-distance target tracking process. The cloud platform is when tracking remote target, and the present control multiplying power can correspond the grow in order to guarantee to see remote target clearly, and the tracking speed that the cloud platform corresponds this moment need correspond the accent and diminish (because some very big that all can lead to image picture variation range very big and cause the target to lose in the picture under the big multiplying power in the cloud platform unit interval of unit time of cloud platform slightly grow), along with the speed that the cloud platform needs diminishes, can turn down cloud platform motor drive current maximum value in step to reduce system's consumption.

Fig. 9 is a schematic view of a motion curve of a pan/tilt head in a tracking process according to an embodiment of the present invention.

The following description will be given by taking the triangular model as an example for pan-tilt velocity control:

since for each camera pan-tilt the maximum velocity performance and the maximum acceleration are known values, the maximum velocity of a given camera pan-tilt is V_maxThe maximum acceleration of the cradle head which can be reached in the process of accelerating to the maximum speed is A_max(ii) a In order to guarantee that the whole acceleration process has enough power to drive the cradle head to normally move, the requirements are as follows: i is_max=(JA_max+T_f)/(N*F_r) (ii) a In the formula T_fThe friction torque of the pan-tilt and the moment of inertia J are set with the cameraKnown value of the correlation, F_rIs a torque parameter associated with the motor flux linkage.

The time of the whole acceleration process is as follows: t =2V_max/A_max. Therefore, when tracking and identity information verification are carried out on a long-distance target, the tracking speed of the holder is assumed to be V₁(much less than V)_max) The maximum acceleration A required for this process in order to keep the acceleration effect constant, i.e. the acceleration time, consistent with that described above_max1The values of (A) are: 2V_max/A_max=2V₁/A_max1；A_max1=V₁/ V_max* A_max。

To ensure acceleration to V₁The whole process moves normally, and the relation between the required torque and the driving current I1 is as follows: f_r*I1=（JA_max1+T_f）/N。

By combining the above formula, the minimum driving current I1 of the motor required for tracking an object with a velocity V1 at a long distance can be calculated as:

。

according to the above formula, when the long-distance target tracking is carried out, the velocity V of the pan-tilt is obtained₁Is smaller than the tripod head V_maxThe current thus obtained is also smaller than the original drive current I_maxThereby reducing system power consumption.

In the embodiment of the invention, more accurate man-vehicle identity matching is realized based on the RFID technology, and the limitation of a simple video analysis mode in a complex environment is solved. Through the cooperative processing of the three holders and the RFID card reader, the change of the magnetic field coverage range of the RFID card reader is realized, the optimal receiving position is kept between the RFID card reader and a target electronic tag, the matching accuracy is improved, the probability of edge missing detection is reduced, and the limitation that the prior art can only monitor in a fixed range is solved. The RFID card reader judges the approaching or the departing of the target according to the object distance information provided by the camera, correspondingly reduces or increases the power, realizes the power adjustment of the RFID card reader, improves the effectiveness of tracking the long-distance target, reduces the missing detection, and simultaneously reduces the power consumption of the RFID card reader when the short-distance target is tracked. And the strategy of synchronously controlling the reduction of the motor driving current is combined, so that the power consumption of the whole system is further reduced, and the system resources are saved.
