Description

Technical Field

[0001] The present invention relates to the field of vehicle detection technology, and in particular to a vehicle headlight detection method, a detection device, and a computer-readable storage medium. Background Art

[0002] Headlights are an active safety component on a car, and they also highlight the car's exterior and decorative style, occupying a crucial position among automotive parts. Headlights, in particular, are crucial for nighttime driving safety, providing sufficient illumination for the driver and alerting other drivers.

[0003] The position of the headlight beam, that is, the position of the headlight optical axis, has strict requirements in the national standard GB7258. If the height is too high or too low, or if it is tilted to the left or right horizontally, it does not meet the national standard requirements, resulting in the driver of this vehicle or other vehicles being unable to drive normally.

[0004] The current quality control method for the position of the light axis of the headlights on automobiles is that after the light axis of the headlights is adjusted on the production line, the inspection project will conduct random inspections and measurements on the vehicles to confirm the stability of the adjustment project, thereby ensuring the quality of the produced vehicles. The adjustment method of the production line is to set up a qualified correction frame in the headlight light axis adjustment equipment of the production line in advance, move the vehicle to the work station, and confirm whether the headlight light axis is in the correction frame. When the headlight light axis is in the correction frame, the equipment automatically determines that it is qualified. When it is not in the correction frame, personnel are required to adjust the light axis with the adjustment screws on the vehicle's headlights and achieve a qualified state. The inspection project detects the position of the headlight light axis through random sampling according to the national standard method, which can more accurately confirm the position accuracy of the vehicle's headlight light axis and then judge the quality status of the adjustment project.

[0005] However, the adjustment data for the production line in the past was not used reasonably, and the sampling method of the inspection project was random. Scientific sampling was not carried out in combination with the adjustment status of the production line. The sampling effectiveness was insufficient and the quality level of the headlight axis accuracy could not be ensured.

[0006] The above content is only used to assist in understanding the technical solution of this application and does not constitute an admission that the above content is prior art. Summary of the Invention

[0074] The specific embodiments of the vehicle of the present invention are basically the same as the embodiments of the vehicle headlight detection program described below, and will not be described in detail here.

[0075] See also Figure 2 , Figure 2 This is a flow chart of a first embodiment of a vehicle headlight detection method according to the present invention. The vehicle headlight detection method provided in this embodiment includes the following steps:

[0076] Step S10, performing optical axis precision adjustment on the vehicle to be adjusted, obtaining a first headlight to be detected of the vehicle after the optical axis precision adjustment, and a target offset of the headlight optical axis corresponding to the first headlight to be detected;

[0077] In this embodiment, the vehicle to be adjusted is a vehicle that needs to undergo optical axis precision adjustment. The first vehicle lamp to be detected is the left headlamp corresponding to the vehicle that has undergone optical axis precision adjustment, or the right headlamp of each vehicle.

[0078] It should be noted that, in this embodiment, the optical axis accuracy can be adjusted by a production line adjustment device. Specifically, the production line adjustment device includes a light sensor, a display screen, a correction frame and a data recording unit, wherein the light sensor is used to determine the center of the optical axis on the display screen according to the strongest light spot of the light of the vehicle to be adjusted on the display screen; the adjustment unit adjusts the optical axis accuracy of the headlights of each vehicle to be adjusted, and records the target offset of the headlights of each vehicle to be adjusted; the correction frame is determined according to the preset reference center of the vehicle to be adjusted, wherein the preset reference center refers to the physical mark on the headlight structure, that is, each vehicle to be adjusted has a different reference center, specifically, the center of the correction frame can be calculated according to 0.9H+50, where H is the reference center, and the border of the correction frame can be the center of the correction frame ±10mm, and the length unit in this embodiment is mm. It should be noted that the national standard GB7258 stipulates that the height of the light axis of the car light should be between 0.8H and H+100, while the center point of the correction frame in this embodiment is 0.9H+50, and the frame height is ±10mm, which fully meets the height of the light axis of the car light stipulated in the national standard.

[0079] In one embodiment, step S10 further includes:

[0080] Step A11, obtaining the light axis center of the vehicle to be adjusted, and adjusting the light axis precision of the vehicle light according to the light axis center and a preset correction frame to obtain a first vehicle light to be detected;

[0081] In this embodiment, the optical axis center of the headlight is the strongest light spot emitted by the headlight, which can be displayed on the above-mentioned display screen. The preset correction frame is the above-mentioned correction frame, and the present invention will not be described in detail here. Specifically, when adjusting the optical axis accuracy, it is necessary to control the optical axis center of the headlight within the correction frame to complete the adjustment of the optical axis accuracy. After completing the optical axis accuracy adjustment, the adjusted headlight also needs to be tested. Therefore, the first headlight to be tested is the left front headlight corresponding to the vehicle that has undergone optical axis accuracy adjustment, or the right front headlight of each vehicle.

[0082] Step A12: Record a first offset between the center of the light axis of the first vehicle lamp to be detected and the center of the preset correction frame, and use the first offset as a target offset.

[0083] In this embodiment, the center of the preset correction frame has been described in the above embodiment and will not be repeated here. In this embodiment, the center of the headlight light axis and the center of the preset correction frame are both located on the same display screen. Therefore, the value of the first offset can be calculated based on the distance between the two points.

[0084] Step S20, classifying the first vehicle lights to be detected according to the target offset and a preset offset threshold to obtain a first vehicle light group to be detected and a second vehicle light group to be detected;

[0085] In this embodiment, step S20 further includes:

[0086] Step A21, comparing the target offset with a preset offset threshold to obtain a comparison result;

[0087] In this embodiment, before executing step A21, a preset offset threshold value needs to be calculated. Specifically, the preset offset threshold value is determined based on the difference between the upper limit of the offset and the fluctuation amount. The upper limit of the offset is the height of the correction frame, and the fluctuation amount can be set to 20% of the height of the correction frame. For example, if the total height of the correction frame is 20 mm, the upper limit is 10 mm and the lower limit is 10 mm. The fluctuation amount can be 20% of the upper or lower limit, that is, 2 mm. Therefore, the preset offset threshold value is 8 mm.

[0088] Step A21: Classify the first vehicle lights to be detected according to the comparison result to obtain a first vehicle light group to be detected and a second vehicle light group to be detected.

[0089] In one embodiment, the step A21 further includes:

[0090] Step A211: if the target offset is greater than or equal to the preset offset threshold, determining the first to-be-detected vehicle headlight as a first to-be-detected vehicle headlight group;

[0091] Step A212: If the target offset is less than the preset offset threshold, the first to-be-detected headlights are determined to be grouped as the second to-be-detected headlights.

[0092] In this embodiment, the comparison results include two types: the target offset is greater than or equal to the preset offset threshold, and the target offset is less than the preset offset. If the target offset is greater than or equal to the preset offset threshold, the first headlight to be detected is determined to be in the first headlight group to be detected; if the target offset is less than the preset offset threshold, the first headlight to be detected is determined to be in the second headlight group to be detected.

[0093] Step S30 : Selecting a number of target headlights to be detected from the first group of headlights to be detected and the second group of headlights to be detected to perform optical axis accuracy detection and obtain detection results.

[0094] In this example, see Figure 3 , Figure 3 A schematic diagram of the scenario for optical axis accuracy testing. First, place the vehicle corresponding to the target headlight to be tested on a standard testing platform so that the headlight is illuminated on the screen. Then use a measuring ruler to measure the first height Di and the second height Bi. The first height is measured and the second height is measured.

[0095] Specifically, in one embodiment, step S30 further includes:

[0096] Step A31: selecting a first number of second headlights to be detected from the first group of headlights to be detected, and selecting a second number of third headlights to be detected from the second group of headlights to be detected, wherein the first number is greater than the second number;

[0097] In this embodiment, the second vehicle headlight to be detected and the third vehicle headlight to be detected are both randomly selected, and the ratio between the first number and the second number is greater than 2.

[0098] Step A32: taking the second to-be-detected vehicle lamp and the third to-be-detected vehicle lamp as target to-be-detected vehicle lamps, and performing an optical axis accuracy test on the target to-be-detected vehicle lamps to obtain a test result;

[0099] In one embodiment, the step A33 further includes:

[0100] Step A331, obtaining the maximum brightness point of the target vehicle lamp to be inspected on a preset screen when the target vehicle lamp is on a preset standard inspection platform;

[0101] Step A332: recording a first height between the position of the maximum brightness point and the preset standard detection platform according to the maximum brightness point;

[0102] Step A333, recording a second height between a preset reference center of the target vehicle lamp to be inspected and the preset standard inspection platform;

[0103] In this example, see Figure 3When a car light shines on a screen, it produces a maximum brightness point with the highest illumination intensity. Therefore, the distance between this maximum brightness point on the screen and the standard detection platform is the first height, Di. The preset reference center of the car light is the physical reference center of the car light structure, and the height between this reference center and the standard detection platform is the second height, Bi. The maximum brightness point can be determined by a light receiver disposed on the screen.

[0104] Step A334: Obtain a detection result based on the first height and the second height.

[0105] In one embodiment, the step A334 further includes:

[0106] Step A3341: Obtain a difference between the first height and the second height according to the first height and the second height;

[0107] Step A3342: If the difference is within the preset threshold, the test result is determined to be qualified;

[0108] Step A3343: If the difference is not within the preset threshold, the test result is determined to be unqualified.

[0109] In this embodiment, the preset threshold can be determined based on the headlight's reference center. Specifically, since the second height is the height between the headlight's preset reference center and the preset standard testing platform, the standard second height is the preset reference center point height. According to national standards, the standard first height in this embodiment can be between 0.8H and H+100. Therefore, the preset threshold can range from 0.8HH to H+100-H. If the difference is within the threshold, the test is considered acceptable; if not, the test is considered unacceptable.

[0110] The present invention proposes a vehicle headlight detection method, comprising the following steps: performing optical axis precision adjustment on a vehicle to be adjusted, obtaining a first headlight to be detected of the vehicle after the optical axis precision adjustment, and a target offset of the headlight optical axis corresponding to the first headlight to be detected; classifying the first headlights to be detected according to the target offset and a preset offset threshold, obtaining a first group of headlights to be detected and a second group of headlights to be detected; and selecting a number of target headlights to be detected from the first group of headlights to be detected and the second group of headlights to be detected for optical axis precision testing, thereby obtaining a test result. Through the above method, the present invention can link the headlight optical axis production line adjustment system with the sampling method of the inspection project, rationally utilize the data of the production line adjustment system, improve the sampling effectiveness of the inspection project, and ensure the quality assurance level of the headlight optical axis precision.

[0122] According to the comparison result, the first vehicle lights to be detected are classified to obtain a first vehicle light group to be detected and a second vehicle light group to be detected.
