Description

Technical Field

[0001] The present application relates to the technical field of vehicle sensor illumination testing, and in particular to a method, device, computer equipment, and computer-readable storage medium for simulating natural illumination testing of an automobile. Background Art

[0002] With the development of intelligent connected vehicles, vehicle-in-the-loop testing has become an important part of ensuring vehicle driving safety. Natural light testing is usually performed on various on-board sensors and intelligent systems on the vehicle to ensure that the vehicle can drive safely in various natural light environments. Although the method of testing in a real natural light environment, such as at night, on sunny days or on cloudy days, ensures the real environment, it is greatly affected by the weather season and time. The required light test environment may not be obtained for a long time, which greatly affects the test efficiency.

[0003] In order to ensure the test efficiency, the test is usually carried out by arranging lighting equipment in the building shell to simulate natural light. Although this method is not affected by the external environment and can be tested anytime and anywhere, when setting up the natural light simulation equipment, it is often only determined by the natural light sensor whether the illumination and uniformity of the simulated natural light are the same as the required real natural light. However, it is impossible to ensure the consistency of the simulated natural light and the real natural light from the perspective of the on-board sensor, which leads to the lack of authenticity of the simulated natural light and affects the final test results of the natural light simulation test.

Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0065] The embodiment of the present application provides a method, device, computer equipment and computer-readable storage medium for simulating natural lighting test of an automobile, which can be applied to a computer equipment, which can be a notebook computer, a desktop computer, a central controller and other electronic devices.

[0066] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0067] Please refer to Figure 1 , Figure 1 A schematic flow chart of a method for simulating a natural lighting test for an automobile provided in an embodiment of the present application.

[0068] like Figure 1 As shown, the method includes steps S1 to S4.

[0069] Step S1, establishing a mapping relationship between first quantitative data and second quantitative data according to a first quantitative data training data set collected by a natural light sensor under real natural light and a second quantitative data training data set collected by a vehicle-mounted sensor on a standard target object.

[0070] It is worth mentioning that natural light sensors are sensors used to detect various parameters of natural light. Vehicle-mounted sensors are mainly installed on vehicles and are mainly used to identify various objects and environments around the vehicle when the vehicle is driving. Vehicle-mounted sensors are easily affected by light when working. Therefore, the essence of conducting lighting tests on vehicles is also a test of the vehicle-mounted sensors installed on the vehicle and the systems associated with the vehicle-mounted sensors.

[0071] Specifically, before establishing a mapping relationship, select quantitative data for the natural light sensor and the vehicle-mounted sensor. Select the illumination, uniformity, and color temperature of the light collected by the natural light sensor under natural light as the quantitative data collected by the natural light sensor, and set them as the first quantitative data. Select the cloud point intensity and reflectivity collected after the vehicle-mounted sensor identifies the standard target under natural light as the quantitative data collected by the vehicle-mounted sensor, and set them as the second quantitative data. The first quantitative data and the second quantitative data can be changed according to specific test requirements.

[0072] Furthermore, after selecting the first quantitative data and the second quantitative data, the natural light sensor is controlled to collect a large amount of first quantitative data under different real natural light conditions to form a first quantitative data training data set, and the natural light sensor at this time is a natural light photosensitive sensor stand. At the same time, the vehicle-mounted sensor is controlled to collect second quantitative data from a standard target under the same real natural light conditions to form a second quantitative data training data set, and the vehicle-mounted sensor at this time is a high-precision vehicle-mounted sensor stand. Among them, the standard target refers to objects such as standard dummies, fake cars, and fake trees used in the test.

[0073] Furthermore, a mapping relationship between the first quantitative data and the second quantitative data is established through machine learning, deep learning and other methods based on the first quantitative data training data set and the second quantitative data training data set.

[0074] Step S2: adjusting the natural light simulation device according to the test requirements so that the actual first quantitative data collected by the natural light sensor under the simulated natural light and the actual second quantitative data collected by the vehicle-mounted sensor on the target object satisfy the mapping relationship.

[0075] Specifically, the test requirements include requirements for natural lighting and requirements for target objects. The target objects are determined according to the test requirements, and the natural lighting parameters are determined according to the natural lighting requirements. Because various data of natural lighting are collected and determined by natural lighting sensors, the natural lighting requirements can be expressed as the ideal first quantitative data that the natural lighting sensor needs to collect.

[0076] Furthermore, after determining the ideal first quantitative data that the natural light sensor needs to collect according to the natural light requirement, the ideal second quantitative data having a mapping relationship with the ideal first quantitative data is determined through the mapping relationship between the first quantitative data and the second quantitative data. The ideal second quantitative data represents the second quantitative data (cloud point intensity and reflectivity) theoretically collected by the on-board sensor of the target object under the natural light required by the test.

[0077] In some embodiments, the natural light simulation device is adjusted to simulate natural light so that the actual first quantitative data collected by the natural light sensor under the simulated natural light is the same as the ideal first quantitative data, and the actual second quantitative data collected by the vehicle-mounted sensor for the target object is the same as the ideal second quantitative data, indicating that the natural light simulated by the natural light simulation device at this time not only meets the requirements of the natural light sensor for natural light, but also meets the requirements of the vehicle-mounted sensor for natural light, and the natural light simulated by the natural light simulation device is more realistic.

[0078] In some embodiments, because there may be a certain color deviation between the target object and the standard target object, it will have a slight impact on the data collected by the vehicle-mounted sensor. A preset error threshold between the actual second quantitative data and the ideal second quantitative data. Adjust the natural light simulation device to simulate natural light so that the actual first quantitative data collected by the natural light sensor under the simulated natural light is the same as the ideal first quantitative data. It is only necessary to make the error between the actual second quantitative data collected by the vehicle-mounted sensor for the target object and the ideal second quantitative data not exceed the preset error threshold. Within the preset error threshold, it can be determined that the natural light simulated by the natural light simulation device meets both the natural light sensor's requirements for natural light and the vehicle-mounted sensor's requirements for natural light.

[0079] Step S3: storing the state of the natural light simulation device.

[0080] It is worth noting that what is stored includes: the current position and current illumination of the natural lighting device.

[0081] Step S4: Use the stored state of the natural light simulation device to perform a natural light simulation test on the automobile.

[0082] As a preferred embodiment, the posture and illumination of the stored natural lighting device are used to simulate natural lighting. Before the test, a built-in light sensor is set in the test environment to collect the first quantitative data of the natural lighting simulated in the test environment after the natural lighting simulation device simulates the natural lighting, and set it as the real-time first quantitative data. The real-time first quantitative data collected by the built-in light sensor in the test environment is obtained, and the real-time first quantitative data is compared with the corresponding ideal first quantitative data to see if there is an error. If there is no error between the real-time first quantitative data and the corresponding ideal first quantitative data, it is determined that the natural lighting simulation device is adjusted in place during the test, ensuring that the authenticity of the simulated natural lighting during the test is high. If there is an error between the real-time first quantitative data and the corresponding ideal first quantitative data, it is possible that the natural lighting simulation device is not adjusted in place during the test, or the natural lighting simulation device fails and the natural lighting simulation device needs to be readjusted.

[0083] like Figure 2 and Figure 3 As shown, the natural light simulation test environment for automobiles uses a building shell constructed of opaque materials, and the selected materials also have the advantage of less interference with communication positioning signals, so that the communication positioning signals can be transmitted over a long distance. A plurality of sets of lighting fixtures for simulating natural light are arranged on the top of the building shell, which constitute a natural light simulation device. The power and illuminance of the lighting fixtures are adjustable, and the spacing and irradiation angle between the lighting fixtures are adjustable. The inner wall of the building shell is equipped with flashlights, glare lights, etc., and street lights are installed on the roadside. The illuminance, irradiation angle and other properties of these lamps are also adjustable to simulate the test of different special lights. The inner wall of the building shell is equipped with a light sensor to collect light data inside the building shell.

[0084] The hardware system of the entire test also includes a radar monitoring device installed on the inner wall of the building shell to monitor the test status of the test vehicle in the building shell and collect relevant data. The automatic door system installed at both ends of the building shell is used to allow the attached vehicle to enter and leave the detection zone. When the automatic door is closed, the building shell provides a closed simulation environment. The radar data and light sensor data are returned to the data acquisition platform through the communication line. The test system also includes a platform and a handheld portable controller to adjust the lighting fixtures and automatic doors for testing.

[0085] During the test, according to the test requirements, the natural lighting conditions stored in the system are selected through the platform or handheld controller, and the natural lighting simulation equipment is controlled to simulate the natural lighting required for the test. At the same time, street lights, glare lights and other equipment can be turned on to conduct tests in special lighting environments.

[0086] Select the automatic or manual mode of automatic hatch opening and closing through the platform or handheld controller. If the automatic mode is selected, the vehicle passes through the entry inspection belt 1 50m away from the entrance, and the entrance hatch is opened. After entering, it passes through the entry inspection belt 2 5m away, and the entrance hatch is closed. At this time, the entire simulation cabin is in a closed state, and relevant natural light simulation tests can be carried out. After the test is completed, when the vehicle is 50m away from the exit, it passes through the departure inspection belt 1, and the exit hatch is opened. When the vehicle passes through the departure inspection belt 2 5m after leaving the simulation cabin, the exit hatch is closed again. In addition, if multiple vehicles or complex scene tests are conducted, the vehicle safety officer can manually control the hatch opening and closing through the handheld controller. During the test, the sensors installed on the inner wall of the building shell will collect the simulated natural light parameter index values ​​in real time for comparison with the set values ​​to ensure the accuracy of the test. At the same time, the internal radar installed on the inner wall of the building shell will also collect the vehicle trajectory and posture behavior for later analysis.
