Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1A is a block diagram of a traffic data reinjection system provided in the present invention, including: a radar data acquisition module 100, a video data acquisition module 200, a traffic data storage module 300, and a reinjection operation execution device 400;
the radar detector acquires traffic detection data including orientation information such as speed, angle, distance and position of each traffic participant by transmitting a probe signal to the traffic participants (for example, vehicles and pedestrians) in the road and comparing a frequency difference between an echo signal and the probe signal when the echo signal reflected by the traffic participants is received; the radar detector may include a laser radar detector, an ultrasonic radar detector, a microwave radar detector, and/or a millimeter wave radar detector; the detection signals of the laser radar are positioned in an infrared band and a visible light band, and the laser is used as a working beam, so that the laser radar has the characteristic of high precision; the detection signal of the ultrasonic radar has strong penetrability in a medium, and is particularly suitable for azimuth measurement in a short distance; the microwave radar uses radio waves with shorter wavelength as detection signals, has better directivity, longer detection distance and stable performance; the Millimeter Wave radar is a detection radar working in a Millimeter Wave band (Millimeter Wave), and has the characteristic of strong anti-interference capability; alternatively, in the embodiment of the present invention, the type of the radar detector is not particularly limited.
The radar data acquisition module 100 is connected to a radar detector, and configured to acquire traffic detection data acquired by the radar detector and send the traffic detection data to the traffic data storage module 300; the radar data acquisition module 100 may be installed inside the radar detector or near the radar detector, and is connected to a communication port of the radar detector, for example, connected to a Controller Area Network (CAN) interface of the radar detector, and acquires the traffic detection data acquired by the radar detector in real time, and sends the traffic detection data to the traffic data storage module 300 through an ethernet interface; the traffic detection data may further include traffic configuration parameters, such as longitude and latitude position information of the radar detector, position information of a traffic line (e.g., a stop line, a channeling line, a lane line, a turning area line, and the like) of a monitoring area corresponding to the radar detector, and position information of a traffic device (e.g., a signal machine, an electric warning rod, and the like).
Particularly, different from the real-time acquisition of the direction information of each traffic participant, after the radar detector is installed, the corresponding traffic area is fixed, so that the traffic configuration parameters are usually fixed values, and the radar detector can directly acquire the traffic configuration parameters through a configuration page; if the traffic area corresponding to the radar detector is changed, the user can modify and update the traffic area through the configuration page; therefore, the radar data acquisition module 100 only needs to acquire the traffic configuration parameters once after detecting that the radar detector is powered on and turned on each time.
Optionally, in the embodiment of the present invention, the radar data obtaining module 100 is specifically configured to perform timing fragmentation and timestamp marking on the traffic detection data, and package the processed traffic detection data and send the packaged traffic detection data to the traffic data storage module 300. The detection signal of the radar detector is sent and received in a certain Time period, which needs to be completed in a certain Time period, for example, in a millimeter wave radar, the detection period is usually about 50 milliseconds, and therefore, the radar data acquisition module 100 performs Time Slicing (Time Slicing) on the traffic detection data of the radar detector according to the detection signal transmission period of the radar detector, marks a timestamp, packs the processed traffic detection data and sends the packed traffic detection data to the traffic data storage module 300, so that the data transmission amount of the traffic detection data is reduced, and the data transmission efficiency is improved.
The video data acquisition module 200 is connected to the road camera assembly, and is configured to acquire a road traffic video captured by the road camera assembly and send the road traffic video to the traffic data storage module 300; the road traffic video visually shows the traffic condition in the road, has extremely high distance measurement precision for each traffic participant in a short distance range, and simultaneously has higher measurement precision for the height information and the width information of each traffic participant; the video data acquisition module 200 can be installed in a road camera assembly or an accessory of the road camera assembly, and can send a road traffic video to the traffic data storage module 300 in a transparent transmission mode; wherein, transparent transmission (Pass-Through), i.e. the transmitted service content is not distinguished, only the transmission content is transmitted from the source address to the destination address, and further the transmission mode of any change is not carried out on the service data content; because the data volume of the video is large and the video data transmission has the characteristic of continuity, the video data acquisition module 200 does not perform any operation on the video data and transmits the road traffic video to the traffic data storage module 300 in a transparent transmission manner, so that the data processing amount is reduced and the transmission efficiency of the video data is improved.
The traffic data storage module 300, connected to the radar data acquisition module 100 and the video data acquisition module 200, is configured to store the traffic detection data and the road traffic video, and time-align the traffic detection data and the road traffic video; the traffic data storage module 300 may be installed in traffic equipment in a road area where the radar detector and the road camera are located, for example, integrated in a traffic light signal control box of the road area, or installed on an electric police pole in the form of a separate device; if the radar data acquisition module 100 and the video data acquisition module 200 respectively perform timestamp marking on the traffic detection data and the road traffic video, the traffic data storage module 300 directly performs time alignment according to the timestamps, so that the traffic detection data at the same time is matched with the road traffic video; if the video data acquisition module 200 does not perform timestamp marking, the traffic data storage module 300 performs time alignment on the traffic detection data and the road traffic video according to the received timestamp after segmenting and compressing the road traffic video.
As shown in fig. 1B, optionally, in the embodiment of the present invention, the traffic data reinjection system further includes: a traffic event acquisition module 500; the traffic event acquiring module 500 is connected to the edge computing device, and is configured to acquire a traffic abnormal event output by the edge computing device and send the traffic abnormal event to the traffic data storage module 300; wherein the traffic abnormal event is obtained based on the fusion data of the traffic detection data and the road traffic video; the traffic data storage module 300 is connected to the traffic event acquiring module 500, and is configured to store the traffic abnormal event and time-align the traffic detection data, the road traffic video, and the traffic abnormal event.
The edge computing equipment is information computing equipment deployed on the road side, is respectively connected with the radar detector and the road camera component, performs characteristic extraction and mode identification processing on traffic detection data and road traffic videos, associates the traffic detection data and the road traffic videos according to categories, and finally fuses the information of the same traffic participant by using a fusion algorithm, for example, the road traffic videos are taken as main information, image characteristic conversion is performed on the direction information of the traffic participant and the direction information is fused in the road traffic videos, the direction information of each traffic participant is marked in the finally obtained road traffic videos, and further traffic abnormal events such as ultrahigh speed, ultralow speed, reverse driving, accident parking, illegal parking, congestion and the like are obtained; optionally, in the embodiment of the present invention, a data fusion manner of the edge computing device is not specifically limited; in particular, the radar detector and the road camera component can be integrated into one electronic device, namely a radar and vision integrated device; the radar detector and the edge computing equipment can also be integrated in the same electronic equipment, namely a radar detection device with a data fusion function; the radar detector may also be integrated in the same electronic device with the road camera assembly and the edge computing device.
Optionally, in the embodiment of the present invention, the traffic event obtaining module 500 is further configured to obtain a traffic configuration parameter output by the edge computing device; the traffic configuration parameters are acquired based on the fusion data of the traffic detection data and the road traffic video, and the traffic configuration parameters comprise at least one of longitude and latitude position information, traffic line position information and traffic device position information. For the acquisition of the traffic configuration parameters, the traffic configuration parameters can be acquired through a configuration page of the radar detector as described in the above technical scheme; accurate traffic configuration parameters can be acquired through edge computing equipment based on a data fusion technology; when the traffic configuration parameters are changed, the changed traffic configuration parameters are sent to the traffic data storage module 300, when the traffic configuration parameters are not changed, the traffic configuration parameters do not need to be sent to the traffic data storage module 300, and the traffic data storage module is directly associated with the radar detection data and the road traffic video according to the obtained traffic configuration parameters.
Compared with the method that user input information is acquired through a configuration page of a radar detector, updating timeliness of the traffic configuration parameters is improved through the traffic configuration parameters acquired through the edge computing device based on data fusion of traffic detection data and road traffic video, for example, when a new traffic line is added to a monitored area, the corresponding traffic configuration parameters can be acquired in time through the mode, meanwhile, compared with parameter loss possibly occurring when the user manually inputs the traffic configuration parameters, the actual environmental information of the monitored area is accurately reflected through the traffic configuration parameters acquired through the edge computing device based on data fusion of the traffic detection data and the road traffic video.
The reinjection operation execution device 400 is configured to inject the time-aligned traffic detection data and the road traffic video into a system under test. The reinjection operation execution device 400 is a terminal device or a server located in the background, and acquires the traffic detection data and the road traffic video by reading the storage hard disk of the traffic data storage module 300, and injects the traffic detection data and the road traffic video into the system to be tested to provide the traffic data in the actual scene for the system to be tested; the tested system may be a real traffic detection device (e.g., an edge computing device to be tested) or a virtual software module.
In particular, in the embodiment of the present invention, the traffic data storage module 300 may store the traffic detection data and the road traffic video in a classified manner according to different types of the abnormal traffic event sent by the traffic event acquisition module 500, such as ultra-high speed, ultra-low speed, reverse driving, accident parking, illegal parking, congestion, and the like; the reinjection operation executing device 400 may, when performing the reinjection, quickly obtain the matched stored data according to the traffic abnormal event tag according to the requirement of the test event, so as to perform a targeted traffic abnormal event test on the tested system, for example, obtain a data segment corresponding to a corresponding event (e.g., illegal parking) through the traffic abnormal event tag, perform a combined reinjection of the data, and repeatedly play the data for multiple times (e.g., 100 times) to test whether the tested system can normally detect illegal parking behaviors; meanwhile, according to different positions of the traffic data storage modules 300, scene tags, such as scene tags at a highway intersection, a highway section, a common intersection, a common road section, a tunnel and the like, can be preset for each traffic data storage module 300, and the reinjection operation execution device 400 can quickly acquire matched stored data according to the scene tags according to the requirements of a test scene when data reinjection is executed, so as to perform targeted scene test on the tested system.
Optionally, in this embodiment of the present invention, the reinjection operation execution device 400 is specifically configured to inject the traffic detection data and the road traffic video into a tested system, and acquire a predicted traffic event returned by the tested system, so as to compare the predicted traffic event with the traffic abnormal event, and acquire an evaluation result of the tested system. The reinjection operation execution device 400 simultaneously injects the traffic detection data and the road traffic video into the edge computing device to be tested, and obtains the traffic event predicted by the edge computing device to be tested, i.e. obtains a predicted traffic event; and the reinjection operation execution device 400 compares the predicted traffic event with the traffic abnormal event output by the edge computing device in the actual scene to obtain the test result of the tested edge computing device.

The wireless communication module may transmit the traffic detection data and the road traffic video stored in the traffic data storage module 300 to the annotating operation execution device 400 through one or more of a video private network, a public security network, a mobile network and the internet, for example, the road traffic video is transmitted through the video private network, and the traffic detection data is transmitted through the public security private network, so as to realize remote transmission of the field traffic data; in addition, if the traffic data storage module 300 further stores the traffic configuration parameters and the traffic abnormal events corresponding to the data, the wireless communication module 600 may further send the traffic configuration parameters and the traffic abnormal events corresponding to the data to the reinjection-operation performing device 400 together, so as to ensure the integrity of the transmitted data.
Optionally, in the embodiment of the present invention, the traffic detection data includes analog-to-digital conversion data, initial point data, and cluster point data. Analog-to-Digital converter (ADC) data, which is a Digital signal acquired by an antenna array of a radar detector through an ADC, represents original data of an echo signal acquired by the radar detector; the initial point data is point location information of traffic participants in the monitored area acquired by the radar detector based on the echo signals; the clustering point location data is a result of point location aggregation of the obtained point location information in the monitoring area by the radar detector, that is, the point location information belonging to the same traffic participant is aggregated, and the azimuth information of one traffic participant is represented by a plurality of pieces of point location information. In particular, different traffic detection data may be respectively injected into different tested systems according to different testing functions of the tested systems, for example, in order to test the antenna performance of the radar (that is, the tested systems are antenna arrays), ADC data may be reinjected; in order to test the performance of the cluster tracking algorithm (namely, the tested system is a cluster tracking module), the initial point data can be reinjected; in order to test the traffic event identification function, the clustering point location data can be reinjected.
