[0047] During the vehicle inspection process, a comprehensive inspection of the vehicle lights (including headlights, front fog lights, rear tail lights, trunk lid tail lights, high-mounted brake lights, rear fog lights and rearview mirror lights, etc.) is required to ensure that the vehicle lights are in normal condition.
[0048] In the related art, generally after the lights are installed, the inspectors observe the lights with their eyes to determine whether the lights are in a normal lighting state. However, the manual inspection solution consumes a lot of manpower costs, and manual inspection is prone to omissions, resulting in poor results of the light inspection.
[0049] In order to solve this technical problem, a headlight inspection system of the present application is proposed, which includes a control module and multiple image acquisition modules, and the image acquisition modules are all connected to the control module; wherein different image acquisition modules correspond to different headlights of the same vehicle to be inspected, so that the headlight images of the corresponding headlight parts of the vehicle to be inspected can be acquired through the image acquisition module, and the control module then inspects the whole vehicle headlights of the vehicle to be inspected according to the headlight images to obtain the headlight inspection results; compared with the related art that relies on the inspection personnel's human eyes to observe to determine whether the headlights are in normal working condition, the present application automatically acquires the vehicle's headlight images for inspection through the image acquisition module and the control module, which can reduce labor costs and reduce possible inspection omissions in manual inspection to improve the effect of headlight inspection.
[0050] The following will describe and introduce the invention through multiple embodiments.
[0051] See also Figure 1 , Figure 1 This is a structural diagram of the first embodiment of the vehicle light inspection system of the present application.
[0052] In this embodiment, the vehicle light inspection system includes a control module 10 and a plurality of image acquisition modules, wherein different image acquisition modules correspond to different vehicle lights of the same vehicle to be inspected, and the image acquisition modules are all connected to the control module 10;
[0053] The image acquisition module is used to acquire the headlight image of the corresponding headlight part of the vehicle to be inspected;
[0054] The control module 10 is used to obtain a headlight image and obtain a headlight inspection result according to the headlight image.
[0055] Specifically, the image acquisition module can be a device such as a camera that can capture the images of each light of the vehicle to be inspected in real time; the control module 10 can be an industrial control cabinet, such as an industrial computer and a power control combination cabinet, etc. The control module 10 can control the working state of the image acquisition module (such as image acquisition frequency, etc.) through a preset control program therein, so that the image acquisition module captures the headlight image of the corresponding headlight part of the vehicle to be inspected. The control module 10 can obtain the headlight image captured by the image acquisition module through the connection with the image acquisition module, and perform the headlight inspection operation of the vehicle to be inspected in combination with the preset inspection logic to obtain the headlight inspection result; the preset inspection logic can include the on and off status of the headlights in normal operating state, thereby determining whether the headlights of the vehicle to be inspected are normal based on the on and off status of the headlights displayed on the captured headlight image and the on and off status of the headlights corresponding to the preset inspection logic.
[0056] In a feasible implementation, the plurality of image acquisition modules may include a first image acquisition module 20, a second image acquisition module 30 and a third image acquisition module 40; wherein the first image acquisition module 20 is used to acquire images of headlights, fog lights and rearview mirror lights of the vehicle to be inspected; the second image acquisition module 30 is used to acquire images of taillights, high-mounted brake lights and rear fog lights of the vehicle to be inspected; the third image acquisition module 40 is used to acquire images of combined taillights and license plate lights of the vehicle to be inspected. It should be noted that the headlights of the vehicle to be inspected generally include combined headlights on the left and right front of the vehicle (including daytime running lights, low beam lights, high beam lights, turn signals and double flash lights); the fog lights may be front bumper fog lights, or left front fog lights and right front fog lights, and the fog lights may differ according to the different models of the vehicle to be inspected; the rearview mirror lights are generally turn signals and double flash lights on the rearview mirror; the taillights of the vehicle to be inspected generally include taillights on the left and right rear of the vehicle (including width lights, brake lights, turn signals and double flash lights); The high-mounted brake light is generally located in the middle of the lower rear gear of the vehicle to be inspected; the rear fog light is a fog light located in the middle of the bottom of the rear bumper of the vehicle to be inspected; the combined taillights of the vehicle to be inspected generally include the combined lights on the left and right rear sides of the trunk lid (including reversing lights, width lights, brake lights, turn signals and double flash lights). For some special models, the rear reversing lights can also be set in the middle of the bottom of the rear bumper of the vehicle like the rear fog lights; the license plate light is generally set in the middle of the trunk lid of the vehicle.
[0057] Figure 2 This is a schematic diagram of the structure of each camera setting in the image acquisition module, such as Figure 2 As shown, in order to facilitate the acquisition of all headlight images of the vehicle to be inspected, the first image acquisition module 20 may include a first camera 21 and a second camera 22. The first camera 21 is configured to be aimed at the left front area of the vehicle to be inspected, and the second camera 22 is configured to be aimed at the right front area of the vehicle to be inspected, so as to acquire the headlight image, fog light image and rearview mirror light image of the vehicle to be inspected; the second image acquisition module 30 includes a third camera 31 and a fourth camera 32. The third camera 31 is configured to be aimed at the left rear area of the vehicle to be inspected, and the fourth camera 32 is configured to be aimed at the right rear area of the vehicle to be inspected, so as to acquire the taillight image of the vehicle to be inspected; the third image acquisition module 40 includes a fifth camera 41 and a sixth camera 42. The fifth camera 41 is configured to be aimed at the left side area of the trunk lid of the vehicle to be inspected, and the sixth camera 42 is configured to be aimed at the right side area of the trunk lid of the vehicle to be inspected, so as to acquire the combined taillight image of the vehicle to be inspected. Figure 2 As shown, each camera can be installed on the top steel structure 00 of the inspection station; the above-mentioned image acquisition modules can also be connected to the intranet of the production enterprise to upload the collected headlight images to the intranet, so as to facilitate the binding and storage of the headlight images and vehicle information for subsequent traceability queries.
[0058] As can be seen from the above content, the license plate light, rear fog light and high-mounted brake light of the vehicle are generally located in the middle of the rear of the vehicle. Therefore, in order to obtain a more accurate image of the vehicle lights, Figure 1 As shown, the vehicle light inspection system may further include an angle adjustment module 50, which is respectively connected to the control module 10, the second image acquisition module 30 and the third image acquisition module 40, and is used to adjust the image acquisition angle of the second image acquisition module 30 and / or the third image acquisition module 40 according to the angle adjustment instruction output by the control module 10. The angle adjustment module 50 may include a servo motor. For example, the servo motor may be connected to a camera bracket, a pan / tilt or a lens mounting bracket. The control module 10 may control the rotation angle of the servo motor to adjust the image acquisition angle of the image acquisition module. For example, in one example, the third camera 31, the fourth camera 32, the fifth camera 41 and the sixth camera 42 may all be connected to a servo motor. When it is necessary to acquire the license plate light image, the servo motor may be controlled to rotate by the control module 10 to adjust the axial angles of the fifth camera 41 and the sixth camera 42 so that they are aligned with the middle area of the trunk lid of the vehicle to be inspected, so that the license plate light image may be acquired more accurately. Similarly, when it is necessary to acquire the rear fog light image and the high-mounted brake light image, the corresponding servo motor may be controlled to rotate by the control module 10 so that the third camera 31 may be aligned with the middle area of the bottom of the rear bumper of the vehicle to be inspected, and the fourth camera 32 may be aligned with the middle area of the lower side of the rear gear of the vehicle to be inspected, so that the rear fog light image and the high-mounted brake light image of the vehicle to be inspected may be acquired more accurately.
[0059] It is worth mentioning that in order to facilitate the calling of the headlight inspection program in the control module 10, the headlight inspection system may also include a trigger module 60, which may be connected to the control module 10, and the trigger module 60 may generate an inspection trigger instruction to the control module 10. After the control module 10 receives the inspection trigger instruction, it may call the preset inspection program and control the image acquisition module to acquire the headlight image, so that the control module 10 may perform the headlight inspection according to the acquired headlight image. In the actual inspection process, it may involve inspecting vehicles of different vehicle models to be inspected, so the trigger module 60 may include multiple trigger buttons, and different button combinations may trigger the headlight inspection program of vehicles of different vehicle models to be inspected.
[0060] In addition, the headlight inspection system may also include a fingerprint module 70 and other actuators 80 (other actuators on the inspection line except the angle adjustment module 50). The operator may verify the identity information through the fingerprint module 70 to ensure that only verified specific operators can perform related operations so that the headlight inspection system executes the headlight inspection program. The control module 10 may also be connected to the equipment on the LCP (Liquid Crystal Polymer) production line to control the operation of the LCP production line; the control module 10 is also connected to the AVI system (Automatic Vehicle Identification). The AVI system may send the information queue of the vehicle to be inspected to the control module 10, so that the control module 10 can configure the corresponding headlight inspection program. At the same time, the control module 10 may also send the headlight inspection results to the AVI system, and after binding with the production instruction information, the AVI system will upload it to the QIS (Quality Information System) for data storage for traceability.
[0061] In this embodiment, the image acquisition module can acquire the headlight image of the corresponding headlight part of the vehicle to be inspected, and the control module then inspects the entire headlight of the vehicle to be inspected based on the headlight image and the preset inspection logic to obtain the headlight inspection result; compared with the related art that relies on the inspection personnel's human eyes to observe to determine whether the headlights are in normal working condition, the present application automatically acquires the vehicle's headlight image for inspection through the image acquisition module and the preset inspection logic in the control module, which can reduce labor costs and possible inspection omissions in manual inspection, so as to improve the effect of headlight inspection.
[0062] Based on the above vehicle light inspection system, the present application embodiment provides a vehicle light inspection method, referring to Figure 3 , Figure 3 This is a flow chart of the first embodiment of the vehicle light inspection method of the present application.
[0063] In this embodiment, the vehicle lamp inspection method includes steps S100 to S200:
[0064] Step S100, acquiring vehicle headlight images acquired by multiple image acquisition modules.
[0065] Among them, different image acquisition modules correspond to different headlights of the same vehicle to be inspected; the headlight image includes multiple headlight images acquired by the same image acquisition module according to preset sampling time and sampling frequency.
[0066] Step S200, obtaining a vehicle headlight inspection result according to a preset inspection logic and a vehicle headlight image.
[0067] Among them, the preset inspection logic includes the on and off conditions of the vehicle lights when they are in normal operating state.
[0068] Specifically, different image acquisition modules correspond to different headlights of the same vehicle to be inspected, and headlight images of different headlight parts of the vehicle to be inspected can be collected. For details, please refer to the description of the headlight inspection system implementation example, which will not be repeated here. Since the working status of the headlights needs to be judged according to the flickering of the vehicle during the headlight inspection, the headlight images can be collected within a certain time range through the image acquisition module. For example, the headlight images can be collected at a sampling frequency of 350ms, and the preset sampling time is set to 2100ms. Thus, one image acquisition module can collect 6 headlight images, and the flickering of the headlights (i.e., the on and off status) is reflected through multiple headlight images, which is convenient for analyzing whether there is a fault or abnormality in the headlights; it should be noted that the preset sampling time and sampling frequency of different image acquisition modules can be the same or different, and can be set according to actual inspection needs.
[0069] It is understandable that there may be design differences between different vehicle models. Therefore, in order to ensure that the image acquisition module can more accurately capture the headlight image, in a feasible implementation, steps A100 to A200 may be further included before step S100:
[0070] Step A100, determining the vehicle model of the vehicle to be inspected.
[0071] Among them, different vehicle models correspond to different preset inspection logics and image acquisition positions.
[0072] Step A200, when receiving an inspection trigger instruction of a vehicle to be inspected, controlling multiple image acquisition modules to adjust to image acquisition positions corresponding to the vehicle model, so that the image acquisition modules acquire images of vehicle lights.
[0073] Specifically, before starting the vehicle headlight inspection, the vehicle to be inspected may be identified through the AVI system. For example, the vehicle model of the vehicle to be inspected may be determined by scanning a unique vehicle identification code such as a QR code on the vehicle body; or as a feasible implementation, step A100 may specifically include steps A110 to A130:
[0074] Step A110, obtaining a vehicle image of the vehicle to be inspected.
[0075] Step A120, matching the vehicle image with at least one preset vehicle model template to obtain a vehicle model matching result.
[0076] Each preset vehicle model template corresponds to a vehicle model.
[0077] Step A130, when there is a vehicle model template matching the vehicle image among all preset vehicle model templates, output vehicle model matching success information, and determine the vehicle model corresponding to the matching vehicle model template as the vehicle model of the vehicle to be inspected.
[0078] The aforementioned image acquisition module can be used to capture and obtain a vehicle image of the vehicle to be inspected (which may include images of different perspectives such as the front and rear of the vehicle); after obtaining the vehicle image of the vehicle to be inspected, the vehicle image is matched with a preset vehicle model template, which may include the position of the vehicle's headlights, the shape of the front of the vehicle, the layout of the lights, and the outline of the vehicle, which can reflect the characteristics of the specific vehicle model; for example, the acquired vehicle image can be feature extracted by an image processing algorithm to extract feature information such as the outline and headlights of the vehicle, and then compared with the features in the preset vehicle model template; if there is a vehicle model template matching the vehicle image in all the preset vehicle model templates, then the vehicle model matching success information can be output, and the corresponding vehicle model can be determined as the vehicle model of the vehicle to be inspected. However, in actual applications, it may be difficult to identify the correct vehicle model from the preset vehicle model template due to the influence of the acquisition clarity of the vehicle image, so when there is no vehicle model template matching the vehicle image in all the preset vehicle model templates, the vehicle model matching abnormal information can be output to prompt the operator to perform manual vehicle model matching to determine the vehicle model of the vehicle to be inspected; thereby, it can be ensured that all vehicles to be inspected can determine their corresponding vehicle models, which is convenient for subsequent vehicle light inspection operations.
[0079] After determining the vehicle model of the vehicle to be inspected, the multiple image acquisition modules can be controlled to more accurately adjust to the image acquisition position corresponding to the vehicle model according to the inspection trigger instruction issued by the operator, so that the image acquisition module can be aimed at the headlight area of the vehicle, so as to collect a clear headlight image. For example, the angle adjustment module 50 in the aforementioned headlight inspection system can be controlled by the control module 10, so that the angle adjustment module 50 can change the image acquisition angle of the image acquisition module and adjust it to the corresponding image acquisition position.
[0080] After the image acquisition module is adjusted to an appropriate image acquisition position, the image acquisition module can be controlled to acquire the headlight image and return it to the control module 10. The control module 10 can perform a headlight inspection according to the preset inspection logic and the acquired headlight image to obtain the headlight inspection result. The preset inspection logic includes the on and off conditions of the headlight in a normal operating state. The headlight image can be used to determine whether the headlight is on or off according to the expected preset inspection logic, thereby obtaining the headlight inspection result.
[0081] Due to different vehicle models, different preset inspection logics may be set. Therefore, after determining the vehicle model of the vehicle, the corresponding preset inspection logic can be determined, and the operator can turn on all the lights of the vehicle to be inspected, and the image acquisition module collects the headlight image. The control module 10 performs a headlight inspection according to the headlight image and the preset inspection logic corresponding to the current vehicle model. When the vehicle to be inspected is the first preset vehicle model, the daytime running lights in the headlight image are all on, the low beam and the high beam are all on, the turn signal and the double flash are all on, the rearview mirror turn signal and the rearview mirror double flash are all on, the left front fog lamp and the right front fog lamp are all on, the width indicator lamp and the brake lamp are all on, the turn signal and the double flash are all on, the reverse lamp in the combination taillight is all on, the license plate lamp is all on, and the high-mounted brake lamp is all on, it can be determined that the headlight inspection result of the vehicle to be inspected is normal.
[0082] When the vehicle to be inspected is the second preset vehicle model, the daytime running lights in the headlight image are all on, the low beam and high beam are all on, the turn signals and the hazard lights are both on and off, the front bumper fog lights are all on, the rearview mirror turn signals and the rearview mirror hazard lights are both on and off, the width lights and brake lights are all on, the turn signals and the hazard lights are both on and off, the reverse lights in the combination taillights are all on, the license plate lights are all on, and the high-mounted brake lights are all on, it can be determined that the headlight inspection result of the vehicle to be inspected is normal.
[0083] When the vehicle to be inspected is the third preset vehicle model, the daytime running lights in the headlight image are all on, the low beam and high beam are all on, the turn signals and the double flash lights are both on and off, the front bumper fog lights are all on, the rearview mirror turn signals and the rearview mirror double flash lights are both on and off, the width lights and brake lights are all on, the turn signals and the double flash lights are both on and off, the turn signals and the double flash lights in the combination tail lights are both on and off, the license plate lights are all on, and the vehicle's rear bumper bottom reversing lights and the rear fog lights are all on, then it can be determined that the headlight inspection result of the vehicle to be inspected is normal.
[0084] If the headlight image of the vehicle to be inspected does not satisfy the judgment logic corresponding to the above-mentioned preset vehicle model, it can be determined that the headlight inspection result of the vehicle to be inspected is a headlight abnormality; when the headlight inspection result is a headlight abnormality, an abnormal prompt information can be output; the abnormal prompt information includes the abnormal headlight location information, so that the operator can confirm in time and perform abnormality elimination operations.
[0085] It is not difficult to understand that the headlight inspection method provided in the embodiment of the present application can obtain headlight images collected by multiple image acquisition modules; wherein different image acquisition modules correspond to different headlights of the same vehicle to be inspected; the headlight image includes multiple headlight images collected by the same image acquisition module according to a preset sampling time and sampling frequency; thus, the headlight inspection result can be obtained according to the preset inspection logic and the headlight image, and the preset inspection logic includes the on and off status of the headlight in normal operation. The present application can automatically collect vehicle headlight images for inspection, which can reduce labor costs compared to the manual inspection method in the related art, and can also reduce possible inspection omissions in manual inspection, thereby ensuring the effectiveness of headlight inspection.
[0086] For example, to help understand the implementation process of the vehicle light inspection method of the first embodiment, please refer to Figure 4 , Figure 4 A brief flow chart of a vehicle lamp inspection method is provided, specifically:
[0087] On the vehicle production line, AVI can issue production instructions, and the operator can trigger the vehicle model recognition program through the LS1 button on the trigger module. The three cameras set at different positions of the vehicle in the image acquisition module (such as the first camera 21 configured to be aimed at the left front area of the vehicle to be inspected, the third camera 31 configured to be aimed at the left rear area of the vehicle to be inspected, and the fifth camera 41 configured to be aimed at the left area of the trunk lid of the vehicle to be inspected) can take pictures at the same time to obtain the vehicle image of the vehicle to be inspected for vehicle model comparison. If the vehicle model comparison is successful, the vehicle model matching success information "X vehicle model comparison OK" can be output. If the vehicle model comparison fails, then The vehicle model matching abnormality information of "vehicle model comparison abnormality" is output. At this time, the vehicle production line stops running, and the operator manually selects the vehicle model. After determining the vehicle model of the vehicle to be inspected, you can wait for the inspection trigger instruction. The LS2, LS3 and LS8 combination buttons on the trigger module correspond to the inspection procedure of the C model (the first preset vehicle model); the LS3 and LS6 combination buttons on the trigger module correspond to the inspection procedure of the L model (the second preset vehicle model); the LS4 and LS7 combination buttons on the trigger module correspond to the inspection procedure of the CHR model (the third preset vehicle model); the cameras of the image acquisition module can be automatically adjusted to the corresponding positions. When the first camera 21 and the second camera 22 collect images of the L model and the CHR model, the preset sampling time can be set to 2100ms, the sampling frequency is 350ms, and 6 images of the headlights are collected; when collecting the fog lamp image of the C model, since the fog lamp position of the C model is different from that of the L model and the CHR model, the seventh camera (camera 7) can be set separately to collect the fog lamp image of the C model, and the preset sampling time of camera 7 can be set to 1500ms, the sampling frequency is 500ms, and 3 fog lamp images are collected; when the third camera 31 and the fourth camera 32 are When collecting the taillight image of the vehicle, the preset sampling time can be set to 2100ms, the sampling frequency is 350ms, and 6 taillight images are collected; when the third camera 31 needs to collect the rear fog light image at the middle position of the rear bumper bottom of the CHR model, the preset sampling time can be adjusted to 1500ms, the sampling frequency is 500ms, and 3 rear fog light images are collected; when the fourth camera 32 is used to collect the high-mounted brake light image at the middle position of the lower side of the rear gear of all models, the preset sampling time is adjusted to 1500ms, the sampling frequency is 500ms, and 3 high-mounted brake light images are collected. When the fifth camera 41 and the sixth camera 42 are used to collect the license plate light image at the middle position of the trunk lid of all models, the preset sampling time of the fifth camera 41 and the sixth camera 42 can be adjusted to 1500ms, and the sampling frequency is 500ms.
[0088] When the LS5, LS6 and LS7 buttons on the trigger module are triggered, you can wait for the high-mounted brake light detection trigger button CB2 to be triggered. At this time, the vehicle warning light flashes, and the voice broadcast "step on the brake" is announced. The high-mounted brake light detection starts timing. When the timing time t≥5s but the CB2 trigger is not detected, the alarm "high-mounted brake light not detected" can be output, and the production line can be controlled to stop. When CB2 is triggered, the position of the corresponding camera can be adjusted for the second time, such as adjusting the position and angle of the fourth camera 32 through a servo motor, so that it is adjusted from the initial position aimed at the right rear area of the vehicle to be inspected to the position that can be aimed at the lower middle area of the rear gear of the vehicle to be inspected, so as to collect the high-mounted brake light image of the vehicle to be inspected. After the position adjustment is completed, the corresponding camera can be controlled to start taking pictures. It should be noted that the number and frequency of camera photos can be controlled separately by the camera's visual program. The captured headlight images can be processed and calculated, and the visual judgment results of the headlight images (i.e., headlight inspection results) can be output. If the inspection results are normal, "Detection OK" will be output; if the inspection results are abnormal, an alarm "X light abnormality" will be output. At this time, the production line can be controlled to stop and manually confirmed until the abnormality is resolved. The collected headlight images and headlight inspection results will be uploaded to the intranet and QIS system, and then the visual system composed of the image acquisition module will be reset, and the control system (i.e., control module) will also be reset to the initial state, waiting for the next headlight inspection operation.
