[0041] See also Figure 1 The present invention provides a vehicle body in white image data acquisition device, comprising:

[0042] A first lifting mechanism 1, a second lifting mechanism 2, a first travel switch 3, a second travel switch 4, a third travel switch 5, a guide rail 6, a first camera device, a second camera device, a third camera device, a sled 7 and a controller;

[0043] The sled 7 is arranged on the guide rail 6 and is used to move the vehicle to be inspected to different working positions;

[0044] In an embodiment of the present invention, the vehicle to be inspected is a body-in-white vehicle. The vehicle to be inspected is placed on a sled 7, and the sled 7 is moved on a guide rail 6 to move the vehicle to be inspected to different working positions. For example, the sled 7 moves the vehicle to be inspected to the positions of the first lifting mechanism 1 and the second lifting mechanism 2 in sequence through the guide rail 6 to fully obtain image data of the vehicle to be inspected.

[0045] The first travel switch 3, the second travel switch 4 and the third travel switch 5 are arranged on the guide rail 6 in sequence;

[0046] In the embodiment of the present invention, during the movement of the slide 7 , the travel switches triggered are in the order of the first travel switch 3 , the second travel switch 4 and the third travel switch 5 .

[0047] The first lifting mechanism 1 is arranged on the guide rail 6 between the first travel switch 3 and the second travel switch 4, and the second lifting mechanism 2 is arranged on the guide rail 6 between the second travel switch 4 and the third travel switch 5. Figure 2-3 The first lifting mechanism 1 is provided with a first sensor for measuring the distance of the front of the vehicle to be detected, and a second sensor for measuring the distance of the roof cover of the vehicle to be detected; the second lifting mechanism 2 is provided with a third sensor for detecting the distance of the tailgate of the vehicle to be detected;

[0048] See also Figure 4-5 , is a schematic diagram of a measuring surface and a measuring distance when measuring distance through a sensor according to an embodiment of the present invention.

[0049] In an embodiment of the present invention, when the sled 7 triggers the first travel switch 3, a control signal is transmitted to the first lifting mechanism 1, and the first lifting mechanism 1 rises from the original position to the working position. After completing the shooting of the front photo, the first lifting mechanism is controlled to descend to the original position, and then the sled 7 continues to move. When the second travel switch 4 is triggered, the first lifting mechanism 1 is controlled to rise to the working position to take photos of the roof cover and the door. After the shooting is completed, the first lifting mechanism 1 is controlled to descend to the original position, and the sled 7 continues to move. When the third travel switch 5 is triggered, the second lifting mechanism 2 is controlled to rise to the working position to take a photo of the tailgate.

[0050] The first camera device, the second camera device and the third camera device are respectively fixedly arranged above the guide rail 6, wherein the first camera device is used to take a photo of the front of the vehicle to be detected, the second camera device is used to take a photo of the roof cover and the door of the vehicle to be detected, and the third camera device is used to take a photo of the tailgate of the vehicle to be detected;

[0051] In the embodiment of the present invention, the first camera device, the second camera device and the third camera device are respectively fixed above the track to take photos of different positions of the vehicle to be detected at fixed angles.

[0052] The controller is connected with the first lifting mechanism 1, the second lifting mechanism 2, the first travel switch 3, the second travel switch 4, the third travel switch 5, the first camera device, the second camera device, the third camera device and the sled 7; and is used to control the movement of the sled 7 along the guide rail 6, and when the sled 7 triggers different travel switches, control the lifting mechanism to rise and fall, and control the camera device to take pictures of the vehicle to be detected.

[0053] The embodiment of the present invention detects the real-time distances of different positions of the vehicle to be detected by means of a first sensor and a second sensor arranged on the first lifting mechanism 1, and a third sensor arranged on the second lifting mechanism 2, thereby triggering different camera devices to take photos according to the real-time distances of different positions of the vehicle, thereby acquiring comprehensive white body image data.

[0054] In one embodiment, the distance between adjacent travel switches and lifting mechanisms is smaller than the distance between the front and rear measuring beams at the bottoms of two adjacent slides 7 .

[0055] In the embodiment of the present invention, the liftable sensor installation structure is as follows: Figure 6 As shown, the mechanical lifting can be controlled by a cylinder to avoid the slide 7, and each group can be equipped with two laser ranging sensors to measure the positions of the two slides 7 before and after, and obtain the position information of the body-in-white according to the relative distance between the slide 7 and the body-in-white.

[0056] See also Figure 7, is a schematic diagram of the travel switch structure of an embodiment of the present invention. In the embodiment of the present invention, the distance between adjacent travel switches and the lifting mechanism is smaller than the distance between the front and rear measuring beams at the bottom of two adjacent sleds 7. When the sled 7 moves and hits the travel switch, the lifting mechanism rises to the working position to measure the relative position of the sled 7, so that it can be applied to dynamic position measurement of all vehicle models. When the sled 7 approaches or moves away from the preset distance of the lifting mechanism, for example, 400mm or 2500mm, the lifting mechanism descends to avoid, and the sled 7 passes.

[0057] In the embodiment of the present invention, due to the poor consistency of the sled 7, it is necessary to prevent the lifting mechanism from colliding with the sensor mounting bracket when it is in a non-working position. The embodiment of the present invention uses a movable mounting plate in combination with a tension spring. In the normal working state, the tension spring keeps the mounting plate in the working position. When the lifting mechanism fails or other reasons cause it to be unable to descend or the sled 7 has poor consistency, the sled 7 hits the mounting plate, and the mounting plate rotates around the rotation point under the action of the sled 7 to avoid it. The sled 7 pulls the mounting plate back to the working position through the rear tension spring.

[0058] See also Figure 8 , which is a schematic diagram of the working process of a white body image data acquisition device provided in an embodiment of the present invention.

[0059] The implementation of the embodiments of the present invention has the following beneficial effects:

[0060] The embodiment of the present invention detects the real-time distances of different positions of the vehicle to be detected by means of a first sensor and a second sensor arranged on the first lifting mechanism 1, and a third sensor arranged on the second lifting mechanism 2, thereby triggering different camera devices to take photos according to the real-time distances of different positions of the vehicle, thereby acquiring comprehensive white body image data.

[0061] See also Fig. 9 The present invention also provides a method for acquiring body-in-white image data, which is applicable to the above-mentioned body-in-white image data acquisition device, comprising:

When the sled 7 triggers the third travel switch 5, the second lifting mechanism 2 is controlled to rise to the working position, and when the tailgate distance of the vehicle to be detected meets the third preset condition, the third camera device is controlled to take a photo of the tailgate of the vehicle to be detected.

[0066] The embodiment of the present invention controls the movement of the slide 7 on the guide rail 6 to trigger the first travel switch 3, the second travel switch 4 and the third travel switch 5 in sequence, thereby controlling the lifting and lowering of different lifting mechanisms, and monitors the distances of different positions of the body-in-white in real time through sensors arranged on the lifting mechanisms, and then triggers cameras at different positions to take photos when preset conditions are met, so as to obtain multiple image data at different distances and angles, thereby effectively improving the comprehensiveness and accuracy of the acquisition of the image data of the body-in-white.

[0067] In one embodiment, when the front distance of the vehicle to be detected meets the first preset condition, controlling the first camera device to take a front photo of the vehicle to be detected includes:

[0068] The first sensor disposed on the first lifting mechanism 1 measures the distance between the front of the vehicle to be detected and the front of the first sensor, and when the distance between the front of the vehicle is within a first preset threshold range, it is determined that the distance between the front of the vehicle meets the first preset condition;

[0069] The first camera device is controlled to take a front photo of the vehicle to be detected at a preset angle.

[0070] In the embodiment of the present invention, the first preset threshold range can be adjusted according to actual needs, for example, the first preset threshold range is 1012mm-400mm, that is, when the distance to the front of the vehicle is within this range, the first camera device is triggered to continuously or intermittently take photos of the front of the vehicle. When the distance to the front of the vehicle is 400mm, the full acquisition of the front of the vehicle is completed, and at this time, the first lifting mechanism 1 can be controlled to descend to the original position to avoid the sled 7.

[0071] The embodiment of the present invention can obtain a comprehensive front photo of the vehicle to be tested by controlling the first camera device to take a front photo of the vehicle to be tested at a preset angle when the front distance of the vehicle is within a first preset threshold range.

[0072] In one embodiment, when the distance of the roof cover of the vehicle to be detected meets the second preset condition, controlling the second camera device to take a photo of the roof cover and the door of the vehicle to be detected includes:

When the roof cover distance is a preset value, the second camera device is controlled to take photos of the roof cover and door of the vehicle to be detected at a preset angle.

[0074] In an embodiment of the present invention, a preset value can be designed according to actual needs. For example, the preset value can be set to 1000mm to trigger the third camera device to take a picture of the fender, and at 291mm, 1091mm, 2091mm and 2890mm, the roof cover and the door are triggered to take pictures, ensuring that pictures of the vehicle in different positions are taken.

[0075] The embodiment of the present invention can obtain comprehensive photos of the roof cover and the doors by controlling the second camera to take photos of the roof cover and the doors of the vehicle when the distance between the roof cover and the doors is a preset value.

When the tailgate distance is less than the lower limit value of the second preset threshold range, the third camera device is controlled to stop shooting, and the second lifting mechanism 2 is controlled to descend to its original position.

[0078] In the embodiment of the present invention, the second preset threshold range can be set according to actual needs, for example, shooting is started when the tailgate distance is 1450 mm, shooting is stopped when it is 2500 mm, and the second lifting structure is controlled to descend to the original position.

[0079] In the embodiment of the present invention, when the tailgate distance is within the second preset threshold range, the third camera is controlled to take photos of the tailgate of the vehicle to be detected, so that multi-angle and comprehensive photos of the vehicle tailgate can be obtained.
