[0056] In order to make the technical solutions and advantages of the present application clearer, the embodiments of the present application will be described in further detail below with reference to the drawings.

[0057] Currently, traffic accidents have become the first killer of the safety of people's lives and property in society, and a large part of the traffic accidents are related to the driver looking down to check the information on the instrument panel or other car display screens. As an auxiliary visual safety driving system of the car, the head-up display device is used to project some important information needed by the driver during driving through the light path of the device onto the front windshield glass of the car. The head-up display device makes the driver no longer need to look down to check the instrument panel during driving, and the eyes can keep staring at the road conditions in front, avoiding the driver from not being able to avoid the oncoming car or other obstacles in time due to looking down, and thus improving the driving safety of the driver.

[0058] In the related art, before the car is shipped and sold, the image displayed by the head-up display device needs to be detected, and the projected virtual image of the head-up display device is usually photographed by a fixed camera, and the projected virtual image is uploaded to an upper computer for comparison detection, so as to detect whether the projected virtual image has optical performance problems such as distortion and ghosting.

[0059] However, the detection means in the related art can only detect whether the projection of the head-up display device has optical performance problems such as distortion and ghosting, and cannot detect whether there is an icon missing phenomenon in the projection of the head-up display device, and the missing of the icon means the missing of the function, which will make the driver unable to know the important information in the driving process of the vehicle in time when checking the head-up display device, and thus the driver cannot make correct response to the sudden situation in time, which seriously affects the safety of the driver driving.

[0060] In order to solve the technical problems in the related art, the embodiment of the present application provides a detection method of a head-up display device of a car, which can ensure that the image projected by the head-up display device of the car detected will not have the phenomenon of function missing, ensure the integrity of the function of the projected image of the head-up display device, and thus ensure the safety of the user driving.

[0065] In some embodiments, the calibration display screen can be replaced by a calibration board. In order to save cost, a bracket that can be adjusted up and down and a calibration board can also be used to replace the calibration display screen, wherein the calibration board is connected with the bracket, and in this case, the icon data to be detected needs to be printed and pasted on the calibration board.

[0066] In some embodiments, the head-up display device 120 comprises an optical machine controller, an adjusting motor and a curved mirror, wherein the adjusting motor is used to adjust the angle of the projection imaging of the curved mirror; the optical machine controller contains an optical machine display screen, which is used to cooperate with the curved mirror to realize the projection imaging.

[0070] Figure 2 A flow chart of a detection method of an automobile head-up display device provided by the embodiments of the present application.

[0071] Referring to Figure 2 The method is applied to a detection terminal, and the method comprises the following steps.

[0072] Step 201: acquiring an image to be detected.

[0075] At step 204, a detection result of the head-up display device is determined based on the integrity of each second icon.

[0076] Therefore, the method for detecting a head-up display device of an automobile provided by the embodiments of the present application can obtain a plurality of first icons from a calibration display screen and a plurality of second icons from a projection image of a head-up display device by acquiring and recognizing a to-be-detected image by a detection terminal.

[0078] In response to the integrity of each second icon meeting the requirement, determining that the detection result of the head-up display device is qualified.

[0085] For each second icon, in response to the difference between the position of the second icon and the position of the first icon corresponding to the second icon being less than or equal to a position threshold, determining that the position of the second icon meets the integrity requirement;

[0086] In response to the difference between the size of the second icon and the size of the first icon corresponding to the second icon being less than or equal to a size threshold, determining that the size of the second icon meets the integrity requirement;

[0087] a difference between the color of the second icon and the color of the first icon corresponding to the second icon is less than or equal to a color threshold value, the color of the second icon is determined to meet the integrity requirement;

[0088] in a case where the position, the size, and the color of the second icon all meet the integrity requirement, the second icon is determined to pass the detection;

[0089] in response to each of the second icons passing the detection, the detection result of the head-up display device is determined to be qualified.

[0090] In some embodiments, in response to any one of the second icons failing to meet the integrity requirement, determining that the detection result of the head-up display device is unqualified comprises:

[0091] for each of the second icons, in response to a difference between the position of the second icon and the position of the first icon corresponding to the second icon being greater than a position threshold value, and / or, a difference between the size of the second icon and the size of the first icon corresponding to the second icon being greater than a size threshold value, and / or, a difference between the color of the second icon and the color of the first icon corresponding to the second icon being greater than a color threshold value, the second icon is determined to fail the detection;

[0092] in response to there being a second icon failing the detection, the detection result of the head-up display device is determined to be unqualified.

[0093] In some embodiments, before the image to be detected is obtained, the method further comprises:

[0094] in response to a detection start instruction, starting the head-up display device and the calibration display screen;

[0095] adjusting the position of the calibration display screen so that the center of the screen of the calibration display screen coincides with the center of the image projected and imaged by the head-up display device;

[0096] obtaining the image to be detected by using the photographing assembly.

[0097] In some embodiments, in response to the detection start instruction, starting the head-up display device and the calibration display screen comprises:

[0098] in response to the detection start instruction, obtaining the model of the head-up display device, and starting the head-up display device;

[0099] based on the model of the head-up display device, sending icon data corresponding to the model of the head-up display device to the calibration display screen for display by the calibration display screen, wherein the icon data comprises a plurality of first icons.

[0100] In some embodiments, after determining the detection result of the head-up display device based on the integrity of each of the second icons, the method further comprises:

[0101] Display the detection result of the head-up display device on the detection display screen.

[0102] Figure 3 Another flowchart of a method for detecting a head-up display device of a vehicle is provided in the embodiments of the present application. Referring to Figure 3 , the method is applied to a detection terminal, and the method comprises the following steps:

[0103] In step 301, the head-up display device and the calibration display screen are started in response to a detection start instruction.

[0104] In some embodiments, referring to Figure 4 , step 301 comprises the following sub-steps:

[0105] In step 3011, the model of the head-up display device is acquired in response to the detection start instruction, and the head-up display device is started.

[0106] Before the method for detecting the head-up display device of the vehicle is performed in the embodiments of the present application, the icon data is input into the detection terminal according to the calibration software and the working logic in the form of a database, and the icon data is classified and stored according to different models of the head-up display device. After the detection start instruction is received, the model of the head-up display device is acquired to find out the icon data corresponding to the model and transmit the icon data to the head-up display device for display.

[0107] In step 3012, the icon data corresponding to the model of the head-up display device is sent to the calibration display screen based on the model of the head-up display device for display on the calibration display screen, wherein the icon data comprises a plurality of first icons.

[0108] When the head-up display device needs to be detected, the detection terminal sends the icon data corresponding to the model of the head-up display device to the calibration display screen based on the model of the head-up display device.

[0109] The icon data in the embodiments of the present application is input into the detection terminal for storage by a team composed of designers, quality personnel, procurement personnel, test personnel, engineering equipment personnel, process personnel, etc. The functions displayed in the icon data are sent to the calibration display screen and the head-up display device in batches through a network cable, a video cable or a control cable (such as CAN / LIN / IIC, etc.) according to the display logic and the function partition.

[0110] For example, the current line transmission speed is 100 ms, assuming the speed limit is 120 Km / h, and the upper limit of the vehicle speed is 180 Km / h, the vehicle speed full function verification needs to be sent 180 times to verify the correctness of the display of all speed icons. Therefore, other icons can be matched and verified based on the number of icons, such as warning icons, speed limit icons, navigation icons, and ADAS display icons. Then, the full function verification takes 18s, and if the individual, ten, and hundred icons on the speed are verified, only 22 outputs are needed, that is, 2.2s. In this case, the warning icons cannot be verified, and the number of warning icons needs to be classified and verified, which requires 56 times of sending pictures, and 5.6s of time. Therefore, according to the analysis, if all display icons are verified for position, size, color, etc., the full function detection takes at least 5.6s. The full function can be arranged according to the 180Km / h full speed display function, or the warning icons can be classified and verified, and the display mode can be selected according to the bottleneck station of the production line. In this case, the production time of the production line is about 2 minutes, and the full function detection can be implemented.

[0111] In step 302, the position of the calibration display screen is adjusted so that the center of the screen of the calibration display screen coincides with the center of the image obtained by the projection imaging of the head-up display device.

[0112] In step 303, the shooting assembly is used to obtain the to-be-detected image.

[0113] It can be understood that when the shooting assembly shoots the to-be-detected image, the image of the calibration display screen and the projection imaging of the head-up display device need to be shot at the same time, and then the two types of images are grouped and compared. Therefore, by adjusting the position of the calibration display screen so that the center of the screen of the calibration display screen coincides with the center of the image obtained by the projection imaging of the head-up display device, the shooting assembly can be facilitated to shoot.

[0114] In step 304, the to-be-detected image is obtained.

[0115] In some embodiments, while the to-be-detected image is obtained, the to-be-detected image is stored in a storage device (such as a sound host).

[0116] In step 305, the to-be-detected image is identified to obtain a plurality of first icons and a plurality of second icons, the first icons are from the calibration display screen, the second icons are from the projection imaging of the head-up display device, and the first icons and the second icons correspond one by one.

[0117] It can be understood that the first icons from the calibration display screen correspond one-to-one with the second icons from the head-up display device.

[0118] At step 306, the integrity of each second icon is determined by comparing the plurality of first icons with the plurality of second icons.

[0119] The integrity of each second icon is determined by comparing the one-to-one corresponding first icon and second icon.

[0120] In some embodiments, referring to Figure 5 Step 306 includes the following sub-steps:

[0121] At step 3061, the position, size and color of each first icon are determined based on each first icon.

[0122] At step 3062, the position, size and color of each second icon are determined based on each second icon.

[0123] At step 3063, the integrity of each second icon is determined by comparing the position, size and color of each first icon and its corresponding second icon.

[0124] It can be understood that whether two sets of images are the same is usually determined by comparing the position, size and color of the icons in the images, and thus, whether a second icon is complete, and whether the image projected by the head-up display device is missing icons, is determined by comparing the differences in the position, size and color of the first icon and its corresponding second icon.

[0125] At step 307, the detection result of the head-up display device is determined based on the integrity of each second icon.

[0126] Specifically, referring to Figure 6 In some embodiments, step 307 further includes the following sub-steps:

[0127] At step 3071, the detection result of the head-up display device is determined as qualified in response to the integrity of each second icon meeting the requirements.

[0128] At step 3072, the detection result of the head-up display device is determined as unqualified in response to the integrity of any second icon not meeting the requirements.

[0129] If the integrity of each second icon meets the requirements, the detection result of the head-up display device is determined as qualified, but if the integrity of any second icon does not meet the requirements, the detection result of the head-up display device is determined as unqualified.

[0130] In some embodiments, step 3071 includes the following sub-steps:

[0131] Step one, for each second icon, in response to a difference between the position of the second icon and the position of the first icon corresponding to the second icon being less than or equal to a position threshold, determining that the position of the second icon meets the integrity requirement.

[0132] Step two, in response to a difference between the size of the second icon and the size of the first icon corresponding to the second icon being less than or equal to a size threshold, determining that the size of the second icon meets the integrity requirement.

[0133] Step three, in response to a difference between the color of the second icon and the color of the first icon corresponding to the second icon being less than or equal to a color threshold, determining that the color of the second icon meets the integrity requirement.

[0134] Step four, in the case that the position, size and color of the second icon all meet the integrity requirement, determining that the second icon passes the detection.

[0135] Step five, in response to each second icon passing the detection, determining that the detection result of the head-up display device is qualified.

[0136] It can be understood that by setting the position threshold, the size threshold and the color threshold, whether the integrity meets the requirement is determined according to the thresholds, so that the determination manner is more specific and feasible.

[0137] In some embodiments, the position threshold and the size threshold can be 1 mm, and the color threshold can be 1 RGB.

[0138] In some embodiments, step 3072 includes the following sub-steps:

[0139] Step one, for each second icon, in response to a difference between the position of the second icon and the position of the first icon corresponding to the second icon being greater than a position threshold, and / or, a difference between the size of the second icon and the size of the first icon corresponding to the second icon being greater than a size threshold, and / or, a difference between the color of the second icon and the color of the first icon corresponding to the second icon being greater than a color threshold, determining that the second icon fails the detection.

[0140] The condition for determining that the second icon fails the detection is determined by setting the threshold.

[0141] In some embodiments, the position threshold and the size threshold can be 1 mm, and the color threshold can be 1 RGB.

[0142] Step two, in response to the second icon failing the detection, determining that the detection result of the head-up display device is unqualified.

[0143] Step 308, displaying the detection result of the head-up display device on the detection display screen.

[0144] After the detection is completed, the detection result is displayed through a detection display screen on the detection terminal.

[0145] Therefore, the method for detecting the head-up display device of the vehicle provided by the embodiments of the present application can solve the problem that the icon missing phenomenon of the image projected by the head-up display device cannot be detected in the related art, ensure the integrity of the function of the image projected by the head-up display device of the vehicle detected, and ensure the safety of the user driving.
