Description

Technical Field

[0001] This application relates to the fields of vehicle driving assistance development and system verification technology, and in particular to a method, device, electronic device and medium for calculating the installation position of a radar under test. Background Technology

[0002] With the rapid development of vehicle intelligence, millimeter-wave radar has been widely used in vehicles. For example, millimeter-wave radar can be integrated into the front or rear bumper of a car. The radar is concealed and does not affect the aesthetics of the vehicle. It can realize the perception of the environment around the vehicle. Millimeter-wave radar emits electromagnetic waves to the outside world and receives the echo to realize the function of detecting the direction and distance of the target, thereby realizing driving assistance functions such as active obstacle avoidance or warning.

[0003] In related technologies, when conducting performance tests on millimeter-wave radar, it is generally necessary to wait until all tooling components are manufactured before testing can be carried out.

[0004] However, due to the long design and development cycle of bumpers, and the complexity and high cost of molds, problems in testing will lead to more complex and costly bumper rectification, which urgently needs to be addressed. Summary of the Invention

[0005] This application provides a method, apparatus, electronic device, and medium for calculating the installation position of a radar under test, in order to solve the problem of uncertainty in the performance evaluation of millimeter-wave radar caused by the excessively long cycle from the development of the bumper to the physical prototyping of the tooling.

[0006] The first aspect of this application provides a method for calculating the installation location of a radar under test, comprising the following steps:

[0007] Calculate the initial installation position of the radar under test, and fabricate the mounting bracket of the radar under test according to the initial installation position;

[0008] Obtain the field of view angle of the radar under test at the installation position, and extract the bumper area within the length of the field of view. Based on the digital model of the bumper area, create a physical sample of the bumper.

[0009] After assembling the physical sample of the bumper and the mounting bracket of the radar under test, the performance of the radar under test is tested, and the optimal installation position of the radar under test is recalculated based on the performance test results. If the optimal installation position is inconsistent with the initial installation position, the optimal installation position is taken as the initial installation position until the preset conditions are met, and the final optimal installation position is taken as the final installation position of the radar under test.

[0010] Based on the above technical means, the problem of uncertainty in the performance evaluation of millimeter-wave radar caused by the long cycle from the development of the bumper to the physical prototype of the tooling was solved, and the development and verification cycle was saved, and potential risks were identified and avoided in advance.

[0011] Further, calculating the initial installation position of the radar under test includes:

[0012] Obtain the installation height of the radar under test and the structural features of the bumper;

[0013] The initial installation position of the radar under test is calculated based on the installation height and structural features.

[0014] Based on the aforementioned technical means, the initial installation position of the radar under test is obtained according to the arrangement height of the radar under test and the structural characteristics of the bumper, so as to facilitate the structural design of the bumper.

[0015] Furthermore, the radar under test is fixed to the mounting bracket by snap-fit ​​and / or screw-fit.

[0016] Based on the above technical means, the radar under test is fixed to the mounting bracket by snap-fit ​​or screw-fit, which can ensure that the relative position of the radar and the bumper is fixed and meets the assembly accuracy requirements.

[0017] Furthermore, the field of view angle is a closed angular region formed by the outward-cone electromagnetic waves emitted by the radar under test.

[0018] Based on the above technical means, the electromagnetic waves emitted by the radar under test are formed into a closed angular region, which makes it easier to verify the impact of the bumper on the performance of the radar under test in the later stage, and the results are more accurate.

[0019] Furthermore, the radar under test is a millimeter-wave radar.

[0020] Based on the aforementioned technical means, millimeter-wave radar uses millimeter waves, whose wavelengths are between centimeter waves and light waves. Compared with centimeter-wave seekers, millimeter-wave seekers are smaller, lighter, and have higher spatial resolution. They have a strong ability to penetrate fog, smoke, and dust, and their anti-interference and anti-stealth capabilities are also superior to other microwave seekers. Therefore, choosing millimeter-wave radar makes it easier to more accurately detect the impact of the bumper on the performance of the radar under test.

[0021] A second aspect of this application provides a device for calculating the installation location of a radar under test, comprising:

[0022] The calculation module calculates the initial installation position of the radar under test and manufactures the mounting bracket of the radar under test according to the initial installation position.

[0023] The module acquires the field of view angle of the radar under test at the installation position, and extracts the bumper area within the length of the field of view. Based on the digital model of the bumper area, a physical sample of the bumper is made.

[0024] The testing module assembles the physical sample of the bumper and the mounting bracket of the radar under test, tests the performance of the radar under test, and recalculates the optimal installation position of the radar under test based on the performance test results. If the optimal installation position is inconsistent with the initial installation position, the optimal installation position is taken as the initial installation position until the preset conditions are met, and the final optimal installation position is taken as the final installation position of the radar under test.

[0025] Furthermore, the computing module is specifically used for:

[0026] Obtain the installation height of the radar under test and the structural features of the bumper;

[0027] The initial installation position of the radar under test is calculated based on the installation height and structural features.

[0028] Furthermore, the above-mentioned device for calculating the installation position of the radar under test is characterized in that the radar under test is fixed to the mounting bracket by snap-fit ​​and / or screw-fit.

[0029] Furthermore, the aforementioned device for calculating the installation position of the radar under test is characterized in that the field of view angle is a closed angular region formed by the electromagnetic waves emitted by the radar under test in a cone shape pointing outwards.

[0030] Furthermore, the aforementioned device for calculating the installation location of the radar under test is characterized in that the radar under test is a millimeter-wave radar.

[0031] A third aspect of this application provides an electronic device, including: a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the program to implement the method for calculating the installation location of a radar under test as described in the above embodiments.

[0032] A fourth aspect of this application provides a computer-readable storage medium having a computer program stored thereon, which is executed by a processor to implement the method for calculating the installation location of a radar under test as described in the above embodiments.

[0033] Therefore, by calculating the initial installation position of the radar under test, fabricating a mounting bracket for the radar based on the initial installation position, obtaining the field of view angle of the radar under test at the installation position, and cropping the bumper area within the viewing angle length, a physical prototype of the bumper is fabricated based on the digital model of the bumper area. After assembling the physical prototype of the bumper and the mounting bracket, the performance of the radar under test is tested, and the optimal installation position of the radar under test is recalculated based on the performance test results. If the optimal installation position is inconsistent with the initial installation position, the optimal installation position is taken as the initial installation position until preset conditions are met, and the final optimal installation position is taken as the final installation position of the radar under test. This solves the problem of uncertainty in the performance evaluation of millimeter-wave radar caused by the excessively long cycle from bumper development to tooling prototype production, saves development and verification cycle, and identifies and avoids potential risks in advance.

Detailed Implementation

[0044] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0045] The following description, with reference to the accompanying drawings, describes a method, apparatus, electronic device, and medium for calculating the installation location of the radar under test according to embodiments of this application.

[0046] Before introducing the method for calculating the installation location of the radar under test in the embodiments of this application, let's briefly introduce the radar performance testing methods in related technologies.

[0047] The related technology discloses a test method and device and system for the impact of bumpers on the performance of millimeter-wave radar. This solution invented a test system and method to evaluate the specific impact of factors such as the difference in the relative position of the radar and the bumper, and the different curvatures of the bumper on the radar performance, thereby providing correct guidance for bumper design and radar layout.

[0048] The related technology also discloses a system for evaluating the impact of bumpers on the performance of vehicle-mounted millimeter-wave radar, which is used to test the specific impact of bumpers on the performance of millimeter-wave radar, thereby determining whether the bumper is acceptable.

[0049] However, neither of the above two solutions takes into account the progress requirements of vehicle development. It is necessary to identify / avoid risks as quickly as possible in order to achieve the goal of mass production on schedule. Both require testing after all tooling parts are manufactured, which results in a long verification cycle, uncontrollable risks, and extremely high rectification costs.

[0050] Based on the aforementioned problems, this application proposes a method for calculating the installation position of a radar under test. In this method, the initial installation position of the radar under test is calculated, a mounting bracket for the radar under test is fabricated based on the initial installation position, the field of view angle of the radar under test at the installation position is obtained, a bumper area within the viewing angle length is selected, a physical sample of the bumper is fabricated based on the digital model of the bumper area, the physical sample of the bumper and the mounting bracket are assembled, the performance of the radar under test is tested, and the optimal installation position of the radar under test is recalculated based on the performance test results. If the optimal installation position is inconsistent with the initial installation position, the optimal installation position is used as the initial installation position until a preset condition is met, and the final optimal installation position is taken as the final installation position of the radar under test. This solves the problem of uncertainty in the performance evaluation of millimeter-wave radar caused by the excessively long development cycle of the bumper from initial design to physical prototyping, saves development and verification time, and identifies and avoids potential risks in advance.

[0051] Specifically, Figure 1 This is a flowchart illustrating a method for calculating the installation location of a radar under test, as provided in an embodiment of this application.

[0052] In step S101, the initial installation position of the radar under test is calculated, and the mounting bracket of the radar under test is made according to the initial installation position.

[0053] Specifically, based on existing technological accumulation, the installation position of the radar can be detected by lidar. LiDAR is a sensor that can accurately detect the position of an object. It emits a laser signal to the target object, calculates the distance based on the time difference of the signal reflected back from the object, and then determines the angle between the object and the transmitter by the angle of the emitted laser, thereby obtaining the relative position of the object and the transmitter.

[0054] Optionally, in some embodiments, calculating the initial installation position of the radar under test includes: obtaining the installation height of the radar under test and the structural features of the bumper; and calculating the initial installation position of the radar under test based on the installation height and structural features.

[0055] Specifically, when deploying millimeter-wave radar, the radar installation height should be higher than 500mm, the bumper surface in front of the radar should be uniform, and the curvature should be greater than 300mm. Based on these boundary conditions, the initial installation position of the radar is determined.

[0056] The millimeter-wave radar is located behind the bumper, which is generally made of plastic and has a specific grade. Since the material, thickness, shape, and paint on the surface of the bumper all affect the performance of the millimeter-wave radar, the bumper is designed with an engineering structure based on its structural characteristics. 3D modeling is then completed to avoid potential risks in advance and shorten the design and development cycle of the bumper.

[0057] Optionally, in some embodiments, the radar under test is fixed to the mounting bracket by snap-fit ​​and / or screw-fit.

[0058] like Figure 2 As shown, the millimeter-wave radar 202 is generally fixed to the mounting bracket by snap-fit ​​or screw-fit to ensure that the relative position of the radar and the bumper is fixed and meets the assembly accuracy requirements.

[0059] In step S102, the field of view angle of the radar under test at the installation position is obtained, and the bumper area within the viewing angle length is captured. A physical sample of the bumper is made based on the digital model of the bumper area.

[0060] Optionally, in some embodiments, the field of view is a closed angular region formed by the outward-cone electromagnetic waves emitted by the radar under test.

[0061] Specifically, such as Figure 3 As shown, the electromagnetic waves emitted by the millimeter-wave radar are cone-shaped and radiate outwards, forming a closed angular region 201. Given that the horizontal field of view (FOV) of a millimeter-wave radar is within a specific angular range, once the millimeter-wave radar is positioned in a specific area of ​​the bumper, it is only necessary to focus on the bumper within the radar's FOV area. The captured local bumper area is larger than the intersection area 205 between the millimeter-wave radar's FOV and the bumper.

[0062] Furthermore, based on the extracted partial bumper, a 3D model is created, and a simple mold is designed to produce a physical sample of the partial bumper. After the mold is completed, the partial bumper sample is manufactured.

[0063] In step S103, after assembling the physical sample of the bumper and the mounting bracket of the radar under test, the performance of the radar under test is tested, and the optimal installation position of the radar under test is recalculated based on the performance test results. If the optimal installation position is inconsistent with the initial installation position, the optimal installation position is taken as the initial installation position until the preset conditions are met, and the final optimal installation position is taken as the final installation position of the radar under test.

[0064] To enable those skilled in the art to further understand the method for calculating the installation position of the radar under test in the embodiments of this application, the following detailed description is provided in conjunction with specific embodiments, such as... Figure 4 As shown.

[0065] Step S401: Determine the location of the millimeter-wave radar based on the appearance design scheme.

[0066] Step S402: Based on the shape, design the structure of the bumper. This design is done through 3D modeling.

[0067] Step S403: Capture the bumper area covered by the FOV. Specifically, based on the horizontal field of view (FOV) of the millimeter-wave radar, focus on the bumper within the horizontal FOV area.

[0068] Step S404: Design a simplified mold based on the cut-off portion of the bumper.

[0069] Step S405: Process and manufacture a partial bumper sample.

[0070] Step S406, Design of radar mounting bracket scheme.

[0071] Step S407: Fabricate the radar mounting bracket using 3D printing. The relative position of the radar and the bumper remains consistent with the design specifications.

[0072] Step S408: Assemble the partial bumper sample with the radar mounting bracket.

[0073] Step S409: Conduct millimeter-wave radar performance testing.

[0074] Step S410: Analyze and evaluate the test results.

[0075] Step S411: If the test passes, the impact of the bumper on millimeter-wave performance is acceptable, and mass production development can proceed based on the design scheme. The verification is complete. If the test fails, the cause analysis should be conducted based on the corresponding problem. Return to step 401, modify and adjust the millimeter-wave radar layout scheme, lock the position, and then conduct the test and verification again according to the above steps.

[0076] Optionally, in some embodiments, the radar under test is a millimeter-wave radar.

[0077] It is understandable that millimeter-wave radar uses millimeter waves, which typically refer to the 30–300 GHz frequency range (wavelength 1–10 mm). The wavelength of millimeter waves is between that of centimeter waves and light waves. Compared with centimeter-wave seekers, millimeter-wave seekers have the advantages of small size, light weight, and high spatial resolution. Millimeter-wave seekers have strong penetration capabilities through fog, smoke, and dust, and their anti-interference and anti-stealth capabilities are also superior to other microwave seekers. Therefore, millimeter-wave radar is selected.

[0078] According to the method for calculating the installation position of the radar under test proposed in this application, the initial installation position of the radar under test is calculated, a mounting bracket for the radar under test is fabricated based on the initial installation position, the field of view angle of the radar under test at the installation position is obtained, the bumper area within the viewing angle length is selected, a physical sample of the bumper is fabricated based on the digital model of the bumper area, the physical sample of the bumper and the mounting bracket are assembled, the performance of the radar under test is tested, and the optimal installation position of the radar under test is recalculated based on the performance test results. If the optimal installation position is inconsistent with the initial installation position, the optimal installation position is taken as the initial installation position until a preset condition is met, and the final optimal installation position is taken as the final installation position of the radar under test. This solves the problem of uncertainty in the performance evaluation of millimeter-wave radar caused by the excessively long cycle from bumper development to tooling prototype production, saves development and verification time, and identifies and avoids potential risks in advance.

[0079] Next, referring to the accompanying drawings, a device for calculating the installation position of the radar under test according to an embodiment of this application is described.

[0080] Figure 5 This is a block diagram of the installation location calculation device for the radar under test according to an embodiment of this application.

[0081] like Figure 5 As shown, the installation location calculation device 10 of the radar under test includes: a calculation module 100, a manufacturing module 200 and a testing module 300.

[0082] The calculation module calculates the initial installation position of the radar under test and manufactures the installation bracket for the radar under test based on the initial installation position.

[0083] The module is used to obtain the field of view angle of the radar under test at the installation position, and to extract the bumper area within the viewing angle length. Based on the digital model of the bumper area, a physical sample of the bumper is made.

[0084] The testing module assembles the physical sample of the bumper and the mounting bracket of the radar under test, tests the performance of the radar under test, and recalculates the optimal installation position of the radar under test based on the performance test results. If the optimal installation position is inconsistent with the initial installation position, the optimal installation position is taken as the initial installation position until the preset conditions are met, and the final optimal installation position is taken as the final installation position of the radar under test.

[0085] Furthermore, the computing module is specifically used for:

[0086] Obtain the installation height of the radar under test and the structural features of the bumper;

[0087] The initial installation position of the radar under test is calculated based on the installation height and structural characteristics.

[0088] Furthermore, the above-mentioned device for calculating the installation position of the radar under test is characterized in that the radar under test is fixed to the mounting bracket by snap-fit ​​and / or screw-fit.

[0089] Furthermore, the aforementioned device for calculating the installation position of the radar under test is characterized in that the field of view is a closed angular region formed by the electromagnetic waves emitted by the radar under test in a cone shape pointing outwards.

[0090] Furthermore, the aforementioned device for calculating the installation location of the radar under test is characterized in that the radar under test is a millimeter-wave radar.

[0091] It should be noted that the explanation of the above-mentioned embodiment of the installation position calculation device for the radar under test also applies to the installation position calculation method of the radar under test in this embodiment, and will not be repeated here.

[0092] The device for calculating the installation position of the radar under test (DUT) according to the embodiments of this application calculates the initial installation position of the DUT, fabricates a mounting bracket for the DUT based on the initial installation position, obtains the field of view angle of the DUT at the installation position, extracts a bumper area within the viewing angle length, fabricates a physical sample of the bumper based on the digital model of the bumper area, assembles the physical sample of the bumper and the mounting bracket, tests the performance of the DUT, and recalculates the optimal installation position of the DUT based on the performance test results. If the optimal installation position is inconsistent with the initial installation position, the optimal installation position is taken as the initial installation position until a preset condition is met, and the final optimal installation position is taken as the final installation position of the DUT. This solves the problem of uncertainty in the performance evaluation of millimeter-wave radar caused by the excessively long development cycle of the bumper from initial design to physical prototyping, saves development and verification time, and identifies and avoids potential risks in advance.

The bus can be an Industry Standard Architecture (ISA) bus, a Peripheral Component Interconnect (PCI) bus, or an Extended Industry Standard Architecture (EISA) bus, etc. Buses can be categorized as address buses, data buses, control buses, etc. For ease of representation, Figure 6 The bus is represented by a single thick line, but this does not mean that there is only one bus or one type of bus.
