[0055] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0056] Refer to Figure 1 , Figure 1 which is a schematic structural diagram of a vehicle appearance optimization device for the hardware operating environment involved in the embodiment solution of the present invention.

[0057] As Figure 1 shown, the vehicle appearance optimization device may include: a processor 1001, such as a Central Processing Unit (CPU), a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005. Among them, the communication bus 1002 is used to realize the connection and communication between these components. The user interface 1003 may include a display screen (Display) and an input unit such as a keyboard (Keyboard). Optionally, the user interface 1003 may further include a standard wired interface and a wireless interface. The network interface 1004 may optionally include a standard wired interface and a wireless interface (such as a Wireless-Fidelity (Wi-Fi) interface). The memory 1005 may be a high-speed Random Access Memory (RAM) memory or a stable Non-Volatile Memory (NVM), such as a disk memory. Optionally, the memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0058] Those skilled in the art can understand that Figure 1 the structure shown in

[0059] As Figure 1 shown, the memory 1005, as a storage medium, may include an operating system, a network communication module, a user interface module, and a vehicle appearance optimization program.

[0060] In Figure 1In the vehicle appearance optimization device shown, the network interface 1004 is mainly used for data communication with a network server; the user interface 1003 is mainly used for data interaction with a user; the processor 1001 and the memory 1005 in the vehicle appearance optimization device of the present invention can be arranged in the vehicle appearance optimization device. The vehicle appearance optimization device calls the vehicle appearance optimization program stored in the memory 1005 through the processor 1001 and executes the vehicle appearance optimization method provided by the embodiments of the present invention.

[0061] Embodiments of the present invention provide a vehicle appearance optimization method. Refer to Figure 2 , Figure 2 which is a schematic flowchart of the first embodiment of a vehicle appearance optimization method of the present invention.

[0062] The vehicle appearance optimization method includes the following steps:

[0063] Step S10: Obtain the sensor acquisition data of the vehicle.

[0064] It should be noted that the execution subject of this embodiment is the control terminal in the vehicle appearance optimization system. The control terminal receives the sensor acquisition data collected by each sensor around the vehicle in the vehicle appearance optimization system and determines the external seam region, the internal fixed region, and the external part region that need to be evaluated for appearance visibility based on the sensor acquisition data. Visibility evaluation is performed on the external seam region, the internal fixed region, and the external part region according to the preset verification rules and sensor data, so as to obtain the evaluation results of each area to be verified. Finally, the control terminal determines the corresponding appearance optimization strategy according to the evaluation results of each area to be verified.

[0065] It can be understood that multiple sensors will be arranged around the vehicle to be evaluated for visibility. The sensor can be placed at the eyes of a mannequin set according to a human model, or can be fixed around the vehicle with a bracket. The sensor can include multiple image sensors and multiple position sensors. The position sensor can locate the current position coordinates, and the image sensor can be used to capture images of the area where the image sensor and the position sensor are located. The different positions of each sensor are used to obtain the acquisition data of different areas of the vehicle. The control terminal obtains the sensor acquisition data of each sensor.

[0066] Step S20: Determine the external seam region, the internal fixed region, and the external part region according to the sensor acquisition data.

[0067] It should be noted that the outer seam region refers to the region where there are gaps at the connection of the hoods on the left and right sides of the vehicle; the internal fixing region refers to the lower part of the instrument assembly inside the vehicle, the vehicle interior trim, which includes the interior trim panels of the pillars, the inner door panels, the interior trim panels of the triangular windows, and regions with water cut strips, etc.; the external part region refers to the regions directly in front of and directly behind the vehicle. The outer seam region, the internal fixing region, and the external part region are all regions of the vehicle to be checked.

[0068] It can be understood that after the control terminal obtains the sensor acquisition data, the outer seam region, the internal fixing region, and the external part region are determined according to the sensor acquisition data of each sensor around the vehicle.

[0069] Step S30: Perform visibility evaluation on the outer seam region, the internal fixing region, and the external part region according to the preset checking rules and the sensor acquisition data to obtain an evaluation result.

[0070] It should be noted that the preset checking rules refer to the standard appearance images corresponding to each region of the vehicle to be checked preset in advance. Visibility evaluation is performed on each region of the vehicle to be checked: the outer seam region, the internal fixing region, and the external part region according to the sensor acquisition data and the preset checking rules, so as to obtain the visibility evaluation results of each region to be checked.

[0071] It can be understood that in order to perform accurate visibility evaluation on each region to be checked based on the sensor acquisition data, further, the performing visibility evaluation on the outer seam region, the internal fixing region, and the external part region according to the preset checking rules and the sensor acquisition data to obtain an evaluation result includes: determining an outer seam image according to the sensor acquisition data and the outer seam region; determining an internal fixing image according to the sensor acquisition data and the internal fixing region; determining an external part image according to the sensor acquisition data and the external part region; performing visibility evaluation on the outer seam image, the internal fixing image, and the external part image according to the preset checking rules to obtain an evaluation result.

[0072] In specific implementation, since the sensor acquisition data includes the acquisition data of multiple image sensors, it is necessary to match the sensor data collected by each image sensor in the sensor acquisition data with each region to be checked, and use the image sensor acquisition data corresponding to the outer seam region in the sensor acquisition data as the outer seam image; use the image sensor acquisition data corresponding to the internal fixing region in the sensor acquisition data as the internal fixing image; use the image sensor acquisition data corresponding to the external part region in the sensor acquisition data as the external part image.

[0073] It should be noted that the visibility of the external seam image, the internal fixation image, and the external part image is evaluated respectively according to the preset verification rules to obtain the evaluation results of each area to be verified.

[0074] It can be understood that in order to obtain accurate evaluation results during the visibility evaluation based on the images corresponding to each area to be verified and the preset verification rules, further, the visibility evaluation of the external seam image, the internal fixation image, and the external part image according to the preset verification rules to obtain the evaluation results includes: comparing the seam verification rule in the preset verification rules with the external seam image to obtain a first evaluation result; comparing the internal part verification rule in the preset verification rules with the internal fixation image to obtain a second evaluation result; comparing the external part verification rule in the preset verification rules with the external part image to obtain a third evaluation result; and obtaining the evaluation result according to the first evaluation result, the second evaluation result, and the third evaluation result.

[0075] In specific implementation, the seam verification rule refers to the standard appearance image corresponding to the vehicle's external seam area preset in the preset verification rules; the internal part verification rule refers to the standard appearance image corresponding to the internal fixation area preset in the preset verification rules; the external part verification rule refers to the standard appearance image corresponding to the external part area preset in the preset verification rules.

[0076] It should be noted that the seam verification rule of the external seam area is compared with the external seam image to obtain a first evaluation result. In the seam verification rule, the standard appearance image collected by the image sensor at the eye position of the 1.88M mannequin within the 15° fan-shaped range of the vehicle seam in the left, right, up, and down directions and with a depth within 60mm is used, and the visible parts such as wiring harnesses, bolts, and brackets are not visible. The specific placement position of the sensor can be as Figure 3 shown. Based on the comparison between the seam verification rule and the external seam image, it is confirmed whether there are visible parts such as wiring harnesses, bolts, and brackets in the external seam image, thereby obtaining the first evaluation result. The size of the mannequin can be other heights, and this embodiment does not limit this.

[0077] It can be understood that the internal part verification rule of the internal fixation area is compared with the internal fixation image to obtain a second evaluation result. In the internal part verification rule, the standard appearance image collected by the image sensor at the eye position of the 1.88M mannequin at the position flush with the vehicle B-pillar and at a certain distance from the vehicle is used, and the visible parts such as wiring harnesses, bolts, and brackets in the lower area of the front instrument panel assembly that are not visible. The specific placement position of the sensor can be as Figure 4As shown, in the standard appearance image collected at the side window of the vehicle and through the window, there is no sharp boundary of the interior visible in the vehicle interior area and no objects that are likely to cause discomfort. The specific placement position of the sensor can be as Figure 5 shown. Based on the internal part checking rules, compare with the internal fixation image to confirm whether there are easily visible components such as wiring harnesses, bolts, brackets, etc. in the lower area of the front instrument panel assembly in the internal fixation area, and confirm whether there is a sharp boundary of the interior visible in the vehicle interior area and whether there are objects that are likely to cause discomfort, so as to obtain the second evaluation result. The size of the mannequin can be other heights, and this embodiment does not limit this.

[0078] In specific implementation, compare the external part checking rules of the external part area with the external part image to obtain the third evaluation result. In the external part checking rules, the content blocked by the front and rear bumpers of the vehicle that cannot be seen in the standard appearance images collected by the image sensors located at the eyes of the mannequins at 1.53M, 1.72M, and 1.88M in the vehicle's due front and due rear and at a certain distance from the vehicle are used. The specific placement position of the sensor can be as Figure 6 shown. Based on the comparison between the external part checking rules and the external part image, confirm whether the content blocked by the front and rear bumpers of the vehicle can be seen in the vehicle's due front and due rear, so as to obtain the third evaluation result. The size of the mannequin can be other heights, and this embodiment does not limit this, but here, mannequins of three sizes are required to install image sensors at the eyes for data collection.

[0079] It should be noted that after obtaining the first evaluation result, the second evaluation result, and the third evaluation result, summarize the first evaluation result, the second evaluation result, and the third evaluation result to obtain the evaluation result.

[0080] Step S40: Determine the appearance optimization strategy according to the evaluation result.

[0081] It should be noted that after obtaining the evaluation results, corresponding appearance optimization strategies need to be determined according to the evaluation results. For example, if there are visible components such as wire harnesses, bolts, and brackets in the external seam image of the first evaluation result, the corresponding appearance optimization strategies can be to remove the visible components, shift the visible components, cover the visible components, spray the surface of the visible components black, change the connection and fixing method of the visible components, etc. in the area corresponding to the visible components in the external seam image; if the sharp boundary of the interior trim and the uncomfortable objects are visible in the internal fixing image of the second evaluation result, the corresponding appearance optimization strategies can be to blacken the windows, widen the lace, optimize the boundaries of the contents, cover, etc. in the window area corresponding to the uncomfortable objects visible in the internal fixing image; if the contents blocked by the front and rear bumpers of the vehicle are visible in the front and rear of the vehicle in the external part image of the third evaluation result, the corresponding appearance optimization strategies can be to optimize the boundaries, move inwards or cover, etc. for the contents or the front and rear bumpers under the condition of meeting the approach angle and departure angle.

[0082] In this embodiment, data collected by sensors of the vehicle is obtained; the external seam area, the internal fixing area, and the external part area are determined according to the data collected by the sensors; visibility evaluation is performed on the external seam area, the internal fixing area, and the external part area according to a preset verification rule and the data collected by the sensors to obtain an evaluation result; an appearance optimization strategy is determined according to the evaluation result. By determining each area to be verified in the external seam area, the internal fixing area, and the external part area of the vehicle through data collected by sensors, and performing visibility evaluation on each area to be verified according to a preset verification rule and the data collected by sensors, an evaluation result is obtained, and an appearance optimization strategy is determined based on the evaluation result, so as to realize the evaluation of the vehicle appearance under a unified standard, complete the optimization of the vehicle appearance, improve the sensory quality and refinement of the vehicle, and improve the customer satisfaction and purchase desire.

[0083] Reference Figure 7 , Figure 7 is a schematic flowchart of the second embodiment of a vehicle appearance optimization method of the present invention.

[0084] Based on the above first embodiment, in the vehicle appearance optimization method of this embodiment, the step S20 includes:

[0085] Step S21: Determine the external seam area of the vehicle according to the seam acquisition data in the data collected by the sensors.

[0086] It should be noted that since there are multiple sensors and the corresponding areas of different sensors are different, it is necessary to obtain the seam acquisition data collected by the sensors at the preset seam positions on the sides of the vehicle. The external seam area refers to the area where there are gaps at the joints of the hoods on the left and right sides of the vehicle. Since the range of the seam acquisition data is large, it is necessary to determine the accurate external seam area based on the seam acquisition data.

[0087] It can be understood that in order to determine the accurate external seam area based on the seam acquisition data, further, determining the external seam area of the vehicle according to the seam acquisition data in the sensor acquisition data includes: determining the contour coordinates according to the seam acquisition data in the sensor acquisition data; performing calibration positioning according to the contour coordinates to determine the calibration positioning points; and determining the external seam area according to the calibration positioning points.

[0088] In a specific implementation, the seam acquisition data includes the coordinates of each acquisition point in the acquisition area. Therefore, based on the seam acquisition data, the cross-sectional contour line coordinates of the side seam of the vehicle are determined, and calibration positioning is performed according to the contour coordinates to determine the calibration positioning points that can obtain the external seam area. The area obtained by connecting each calibration positioning point is the external seam area.

[0089] It should be noted that in order to obtain accurate calibration positioning points based on the contour coordinates, further, performing calibration positioning according to the contour coordinates to determine the calibration positioning points includes: determining the target contour tangent points according to the contour coordinates; determining the midpoint of the connection line, the first straight line, and the second straight line according to the target contour tangent points; and determining the calibration positioning points according to the target contour tangent points, the midpoint of the connection line, the first straight line, and the second straight line.

[0090] It can be understood that the target contour tangent points refer to the tangent points on the outermost contour line of the cross-sectional contour line of the seam, the midpoint of the connection line refers to the midpoint between the target contour tangent points, the first straight line refers to a straight line that deviates outward by a certain distance from the connection line of the target contour tangent points, and the second straight line refers to a straight line that deviates inward by a certain distance from the connection line of the target contour tangent points. The calibration positioning points can be determined according to the target contour tangent points, the midpoint of the connection line, the first straight line, and the second straight line.

[0091] In a specific implementation, in order to obtain accurate calibration positioning points, further, determining the calibration positioning points according to the target contour tangent points, the midpoint of the connection line, the first straight line, and the second straight line includes: determining the third straight line according to the target contour tangent points and the midpoint of the connection line; determining the reference point according to the first straight line and the third straight line; determining the first tangent point and the second tangent point according to the reference point; and determining the calibration positioning points according to the first tangent point, the second tangent point, the first straight line, and the second straight line.

[0092] It should be noted that the third straight line refers to the straight line perpendicular to the connecting line of the target contour tangent points drawn through the midpoint of the connecting line. The reference point is the intersection point of the first straight line and the third straight line. Two tangent lines are drawn from the reference point to the outer contour line of the slit. The tangent points of the two tangent lines are the first tangent point and the second tangent point respectively. Two straight lines are drawn from the first tangent point and the second tangent point respectively at an angle of 15° with the two tangent lines. The two straight lines intersect the second straight line at the first intersection point and the second intersection point respectively. The first intersection point, the second intersection point, the first tangent point and the second tangent point are the calibration positioning points.

[0093] It can be understood that, as Figure 8 shown, for the Z-direction demarcation slit, the vehicle body is cut by a plane perpendicular to the Z direction. According to the contour coordinates, the cross-sectional contour line of the slit is obtained. The P1 and P2 tangent points (i.e., the target contour tangent points) on the outermost contour line are extracted, and the P1 and P2 points are connected to obtain the midpoint P0 of the line segment P1P2 (i.e., the midpoint of the connecting line). A straight line L1 perpendicular to the line segment P1P2 is drawn through the midpoint P0, and it intersects with the straight line L2 (i.e., the first straight line) obtained by offsetting the line segment P1P2 outward by 150 mm at the point V0 (i.e., the reference point). Tangent lines L3 and L4 are drawn from the point V0 to the outer contour line of the slit, and the tangent points are P3 (i.e., the first tangent point) and P4 (i.e., the second tangent point) respectively. Straight lines L5 and L6 are drawn from the P3 and P4 points respectively at an angle of 15° with the L3 and L4 straight lines. The two straight lines intersect the straight line obtained by offsetting the line segment P1P2 inward by 60 mm (i.e., the second straight line) at the P5 and P6 points (the left and right limit vertices). The L5 and L6 straight lines are extended in the reverse direction and intersect with L2, and the V1 and V2 points (the viewpoints of the left and right moving areas of the sensor) are obtained. The quadrilateral area surrounded by the P3, P4, P5, and P6 points is the outer slit area, as Figure 9 shown. For the X-direction demarcation slit, the vehicle body is cut by a plane perpendicular to the X direction; for the Y-direction demarcation slit, the vehicle body is cut by a plane perpendicular to the Y direction. The determination methods of the calibration positioning points and the outer slit area remain unchanged.

[0094] Step S22: Determine the internal fixed area of the vehicle according to the window acquisition data in the sensor acquisition data.

[0095] It should be noted that the sensor acquisition data at the position flush with the B-pillar of the vehicle and at a certain distance from the vehicle and the sensor acquisition data at the side window of the vehicle are obtained and used as the window acquisition data. The area corresponding to the window acquisition data is the internal fixed area.

[0096] Step S23: Determine the external part area of the vehicle according to the rear vehicle acquisition data in the sensor acquisition data.

[0097] It should be noted that the sensor acquisition data in front of and behind the vehicle and at a certain distance from the vehicle are obtained and used as the rear - end acquisition data. The area corresponding to the parking space acquisition data is the external part area.

[0098] In this embodiment, the external seam area of the vehicle is determined according to the seam acquisition data in the sensor acquisition data; the internal fixed area of the vehicle is determined according to the window acquisition data in the sensor acquisition data; and the external part area of the vehicle is determined according to the rear - end acquisition data in the sensor acquisition data. The sensor acquisition data is accurately classified, so as to accurately locate each area to be verified based on the sensor acquisition data, thereby further improving the accuracy in subsequent visibility evaluation.

[0099] In addition, referring to Figure 10 , an embodiment of the present invention also proposes a vehicle appearance optimization device, which includes:

[0100] An acquisition module 10, configured to acquire the sensor acquisition data of the vehicle;

[0101] A determination module 20, configured to determine an external seam area, an internal fixed area, and an external part area according to the sensor acquisition data;

[0102] An evaluation module 30, configured to perform visibility evaluation on the external seam area, the internal fixed area, and the external part area according to a preset verification rule and the sensor acquisition data to obtain an evaluation result;

[0103] The determination module 20 is further configured to determine an appearance optimization strategy according to the evaluation result.
