Technical Field

[0001] The present invention relates to the field of roadside perception equipment testing, and in particular to a roadside perception equipment testing and evaluation method. Background Art

[0002] Roadside perception equipment is widely used in the field of intelligent transportation, and the test results of its equipment performance play an important reference role in equipment selection.

[0003] In the current performance testing of roadside sensing equipment, an ideal testing environment without any interference is often built, with only one or several motor vehicles slowly driving through the testing area. The roadside sensing equipment testing accuracy results obtained by this testing method cannot serve as a guide in actual projects. Especially in the case of ultra-wide sections and ultra-multiple lanes (i.e., 10 lanes or more in both directions) and ultra-large traffic (i.e., highways with daily traffic volume of more than 150,000 vehicles), the existing testing methods are difficult to accurately evaluate.

[0004] Therefore, based on actual engineering needs, the present invention proposes a roadside perception equipment testing and evaluation method. Summary of the invention

[0021] Draw a data heat map; the data heat map is drawn based on the detection data recorded by the roadside perception device. The more vehicles there are in a unit area during the statistical period, the darker the color of the heat map is, the better the continuous tracking of the target is, and the longer the continuous distance of the heat map is, which is used to qualitatively judge the perception situation of the perception device;

[0022] The number of lane-specific target section detections by the roadside perception device, the number of lane-specific target section detections by the camera, the lane-specific target detection rate, and the data heat map are output as test results of the impact of roadside interference facilities on the detection and tracking effects of roadside perception equipment.

[0023] As a preferred embodiment of the present invention, the method further comprises testing the road noise barrier, comprising the following steps:

[0024] Q1: Select the best acquisition position of the roadside sensing device to be tested based on the results output by S5, and use the other side of the highway noise barrier in the driving direction as the installation position of the roadside sensing device to be tested and the camera;

[0040] The calculation method of the lane-by-lane networking rate of the same-direction roadside perception device and the lane-by-lane networking rate of the opposite roadside perception device is: the ratio of the number of lane-by-lane target matches to the actual number of vehicles passing through the corresponding lane of the same section within the statistical period.

[0041] As a preferred solution of the present invention, the actual number of vehicles is obtained by analyzing the image data recorded by the camera through a video image algorithm.

[0054] The present invention is further described in detail below in conjunction with test examples and specific implementation methods. However, this should not be understood as the scope of the above subject matter of the present invention being limited to the following embodiments, and all technologies realized based on the content of the present invention belong to the scope of the present invention.

[0055] Example 1

[0056] like Figure 1 As shown, a roadside perception device testing and evaluation method includes the following steps:

[0057] S1: Select a test data collection location from a preset location;

[0058] The test data collection position includes the relative distance between the roadside sensing device to be tested and the roadside interference facilities, the layout position of the roadside sensing device to be tested, and the installation height of the roadside sensing device to be tested.

[0059] S2: Setting the roadside perception device and the camera to be tested at the test data collection position, and adjusting the installation angles of the roadside perception device and the camera to be tested.

[0060] S3: The roadside perception device records detection data, and the camera records image data.

[0061] S4: Select an unused test data collection position from the preset positions, and enter S2 until all the test data collection positions in the preset positions have completed recording.

[0062] S5: Based on the acquired detection data and image data of each test data collection position, the test results of the roadside equipment at each test point are evaluated, and the evaluation results are output as test results of the impact of roadside interference facilities on the detection and tracking effect of the roadside perception equipment.

[0063] Example 2

[0064] This embodiment is a specific implementation scheme of the method for testing and evaluating a roadside sensing device described in Embodiment 1, and includes the following steps:

[0065] S1: Select a test data collection location from a preset location;

[0066] The test data collection position includes the relative distance between the roadside sensing device to be tested and the roadside interference facilities, the layout position of the roadside sensing device to be tested, and the installation height of the roadside sensing device to be tested.

[0067] Among them, the roadside sensing equipment is a radar-vision integrated device or a millimeter-wave radar; the roadside interference facilities include: roadside noise screens and / or roadside signs and / or gantry signs and / or street light poles set up along the road.

[0068] Among them, Figure 2 As shown, this embodiment uses a certain section of highway as the test section, and selects the distance between the integrated radar and the gantry variable information board. In this embodiment, the preset positions include relative distances of 100 meters, 200 meters, and 300 meters; the installation heights are 6 meters, 8 meters, and 10 meters. Since the distance between each integrated radar and the gantry variable information board needs to be recorded and analyzed at different heights, the preset positions include 9 test data collection positions, and a total of 9 tests are required.

[0069] S2: Setting the roadside perception device and the camera to be tested at the test data collection position, and adjusting the installation angles of the roadside perception device and the camera to be tested.

[0070] In this embodiment, the test data collection position and the installation angle are adjusted by a remote control pan-tilt head arranged on the lifting vehicle, and the test data collection position is located above the emergency lane.

[0071] Further, such as Figure 3 As shown, this embodiment also includes an auxiliary testing device, which includes a lifting vehicle mounting bracket, a remote control pan-tilt head and a pan-tilt head mounting part, a radar-vision integrated machine mounting part, a variable focal length camera and a camera mounting part; the auxiliary testing device is installed on the lifting vehicle, and the radar-vision integrated machine, the remote control pan-tilt head and the variable focal length camera are installed on the auxiliary testing device.

[0072] In this embodiment, the lift truck is driven into the emergency lane, stopped at the selected position, the integrated radar and visual device to be tested is installed on the remote control pan-tilt, a variable focal length camera is installed, and the vehicle is lifted to the test installation height. The tester adjusts the installation angle of the integrated radar and visual device through the remote control pan-tilt until it meets the test requirements.

[0073] S3: The roadside sensing device records detection data, and the camera records image data. The recording time is generally controlled between 30 minutes and 1 hour, and the recording time in this embodiment is 30 minutes.

[0074] S4: Select an unused test data collection position from the preset positions, and enter S2 until all the test data collection positions in the preset positions have completed recording.

[0075] S5: Evaluate the test results of the roadside equipment at each test point based on the test data and image data obtained at each test data collection location, and output the evaluation results as test results of the impact of roadside interference facilities on the detection and tracking effect of roadside perception equipment. Specifically:

[0076] According to the detection data of each test data collection position, the number of targets appearing in several sections in different lanes is counted to obtain the corresponding number of lane-by-lane target section detections of the roadside perception equipment.

[0077] According to the image data of each test data collection position, the number of targets appearing in several sections of different lanes is counted through the target detection algorithm to obtain the corresponding number of targets detected by the camera in each lane section.

[0078] Calculate the lane target detection rate; lane target detection rate = number of lane target sections detected by the roadside perception equipment / number of lane target sections detected by the camera.

[0079] Draw a data heat map; the data heat map is drawn based on the detection data recorded by the roadside perception device. The more vehicles there are in a unit area during the statistical period, the darker the color of the heat map, the better the continuous tracking of the target, and the longer the continuous distance of the heat map, which is used to qualitatively judge the perception situation of the perception device.

[0080] The number of lane-specific target section detections by the roadside perception device, the number of lane-specific target section detections by the camera, the lane-specific target detection rate, and the data heat map are output as test results of the impact of roadside interference facilities on the detection and tracking effects of roadside perception equipment.

[0081] Furthermore, in this embodiment, the lanes are divided into lanes 1 to 5 to the left in the driving direction, and the cross-sections are divided from 100 meters to 350 meters at intervals of 50 meters.

[0082] According to the detection data of each test data collection position, the number of targets appearing in several sections in different lanes is counted to obtain the corresponding number of lane-by-lane target section detections of the roadside perception device;

[0083] According to the image data of each test data collection position, the number of targets appearing in several sections of different lanes is counted by the target detection algorithm to obtain the corresponding number of targets detected by the camera in each lane section;

[0084] Calculate the lane target detection rate; lane target detection rate = number of lane target sections detected by the roadside perception equipment / number of lane target sections detected by the camera.

[0085] In this embodiment, by analyzing the recorded data, the test part analysis results are obtained as follows:

[0086] Table 1 Test results of the first test unit

[0087]

[0088] like Figure 4 As shown in the figure, based on the analysis of the lane detection rate results, the lane detection rate of the integrated radar and vision device on a 5-lane road section with a 30-minute traffic volume of 2,618 motor vehicles decreases continuously with the increase of tracking distance.

[0089] Since the distance between the integrated radar and the gantry-type information board is 300 meters, when the tracking distance of the integrated radar and the gantry-type variable information board reaches 300 meters, its tracking rate shows an obvious turning point due to the influence of the gantry-type variable information board. Therefore, we can draw the following conclusions:

[0090] In this embodiment, the tracking rate of the integrated radar and vision device dropped significantly when it was 300 meters away from the gantry information board, indicating that the gantry information board had a greater impact on the tracking ability of the integrated radar and vision device at this distance. Moreover, on a 5-lane road with a 30-minute traffic volume of 2,618 vehicles, the tracking ability of the test integrated radar and vision device can still maintain a high level in lanes 1 and 2, but the tracking ability in lanes 3, 4, and 5 is poor.

[0091] Example 3

[0092] The difference between this embodiment and embodiment 2 is that the method further includes testing the road noise barrier, including the following steps:

[0093] Q1: Select the best acquisition position of the roadside perception device to be tested according to the results output by S5, and take the other side of the highway noise barrier in the driving direction as the installation position of the roadside perception device to be tested and the camera.

[0094] In this embodiment, the road noise barrier is arranged on the left side of the driving direction. Therefore, in order to test the influence of the road noise barrier on the detection and tracking effect of the integrated radar and vision device, the installation position of the integrated radar and vision device is selected to be on the right side of the driving direction.

[0095] According to the evaluation and analysis results of S5, the current test radar-vision integrated machine can obtain the best detection and tracking effect when it is installed at a height of 8 meters and 200 meters away from the gantry-type variable information board compared with other test schemes. Therefore, in this embodiment, the installation position of the radar-vision integrated machine is 200 meters away from the gantry-type variable information board and on a pole with a height of 8 meters.

[0096] Q2: Set up the roadside sensing equipment and cameras to be tested; set up the roadside sensing equipment and cameras by laying out poles or lifting vehicles.

[0097] Q3: The roadside perception device to be tested records detection data, and the camera records image data; the recording time of this embodiment is 30 minutes.

[0098] Q4: Based on the detection data and image data recorded in S3 and Q3, generate the number of lane-specific target section detections by the roadside perception device, the number of lane-specific target section detections by the camera, and a data heat map.

[0099] In this embodiment, the recorded data is analyzed to obtain a data heat map, such as Figure 5 and Figure 6 shown.

[0100] Q5: Calculate the lane target detection rate based on the number of lane target section detections by the roadside perception equipment and the number of lane target section detections by the camera generated in Q4.

[0101] Q6: The lane-by-lane target detection rate and data heat map output by S5, the lane-by-lane target detection rate output by Q5, and the data heat map output by Q4 are used as test results of the impact of highway noise barriers on the detection and tracking effects of the roadside perception equipment to be tested.

[0102] pass Figure 5 It can be seen that when a noise barrier is installed on the right side of the driving direction, the detection and tracking effect of the radar vision integrated device installed on the side close to the noise barrier is better than when it is installed on the side far away from the noise barrier.

[0103] Example 4

[0104] The difference between this embodiment and embodiment 3 is that the method further includes testing of cross-device continuous tracking capability under ultra-wide sections, ultra-multi-lanes, and ultra-large traffic, including the following steps:

[0105] E1: Select the optimal installation height of the roadside perception equipment according to the output result of S5; in this embodiment, the optimal installation height of the radar and vision integrated device is 8 meters.

[0106] E2: According to the result of Q6 output, select the side that is less affected by the highway noise barrier in the driving direction as the installation side of the roadside sensing device; further, when the radar-vision integrated device in this embodiment is installed on the side close to the noise barrier on a road covered by the noise barrier, the effect of the noise barrier is minimal. Therefore, in this embodiment, the radar-vision integrated device to be tested is installed on the side close to the noise barrier.

[0107] E3: Three groups of roadside sensing devices and cameras are arranged at equal intervals at the optimal installation height on the installation side; in this embodiment, the interval is set to 300 meters.

[0108] E4: In the order of driving direction, the collection direction of the two groups of roadside perception devices and cameras in the front of the driving direction is set to the driving direction; the collection direction of the group of roadside perception devices and cameras behind the driving direction is set to the opposite direction of driving.

[0109] E5: If Figure 7 As shown, two groups of roadside perception devices and cameras with the same collection direction are selected, detection data and image data are recorded (recorded for 1 hour in this embodiment), the number of lane target matches in the detection overlap area is obtained, and the lane networking rate of the roadside perception devices in the same direction is calculated; the detection overlap area is the overlapping part of the corresponding target detection coverage range of the two groups of roadside perception devices tested.

[0110] The lane target matching number is the count value of the same target detected by two tested roadside sensing devices at the same time, at the same location, and in the same lane during the statistical period.

[0111] The calculation method of the lane-by-lane networking rate of the same-direction roadside perception device and the lane-by-lane networking rate of the opposite roadside perception device is: the ratio of the number of lane-by-lane target matches to the actual number of vehicles passing through the corresponding lane of the same section within the statistical period.

[0112] The actual number of vehicles is obtained by analyzing the image data recorded by the camera through a video image algorithm.

[0113] Furthermore, the calculation results are as follows:

[0114] Table 2 Lane-based networking rate

[0115]

[0116] E6: If Figure 8 As shown, two groups of roadside perception devices and cameras behind the driving direction are selected, detection data and image data are recorded, the number of lane-by-lane target matches in the detection overlap area is obtained, and the lane-by-lane networking rate of the reverse roadside perception device is calculated.

[0117] Furthermore, the calculation results are as follows:

[0118] Table 3 Networking rate of integrated radar and vision devices by lane

[0119]

[0120] E7: Based on the output results of E5 and E6, it is used as the test result of the cross-device continuous tracking capability under ultra-wide sections, ultra-multi-lanes, and ultra-large traffic.

[0121] In this embodiment, according to the above calculation results, it can be known that when two integrated radar and vision devices are arranged in the order of driving direction and have the same illumination direction, the networking rate of the first two lanes close to the installation location of the integrated radar and vision device is maintained above 80%, and the networking rate of the 3rd, 4th and 5th lanes is significantly lower than that of the first two lanes.

[0122] When two integrated radar and vision devices are arranged in the order of driving direction and with opposite illumination directions, only the lane closest to the integrated radar and vision device can maintain a networking rate of more than 80%, and the networking rate of each lane is lower than that of the networking scheme in which the two integrated radar and vision devices have the same illumination direction.
