[0028] The present application provides a vehicle door and window detection system 10 for rain lines. Figure 1 It is a structural schematic diagram of an embodiment of a vehicle door and window detection system 10 for rain lines provided in the present application.

[0029] Combination Figure 1The vehicle door and window detection system 10 of the rain line includes a bracket 11, a detection device 12, an image acquisition device 13 and an image processing device (not shown). The bracket 11 is arranged on the vehicle transmission route of the rain line, and at least part of the detection device 12 and the image acquisition device 13 are arranged on the bracket 11.

[0030] Specifically, a conveying device 14 is provided on the rain line, and the conveying device 14 is provided on the vehicle conveying route. The conveying device 14 is used to convey the vehicle 21 to be tested, so as to convey the vehicle 21 to be tested into the rain chamber 22, so that the vehicle to be tested is subjected to the rain test in the rain chamber 22. At this time, the vehicle conveying route can be a straight route, and the conveying device 14 is also a straight device, such as the conveying device 14 can be a conveyor belt, etc. At this time, the bracket 11 is provided on the vehicle conveying route, and can be provided on one side of the vehicle conveying route, or can be provided across the vehicle transmission route. It should be understood that the provision of the bracket 11 will not affect the normal delivery of the vehicle 21 to be tested.

[0031] Specifically, the detection device 12 is at least partially disposed on the bracket 11, and the detection device 12 is used to detect whether the vehicle 21 to be tested has entered the preset position, and the preset position is located in front of the rain shower room 22. The detection device 12 may include multiple components, and at least some of the components are disposed on the bracket 11, so as to facilitate the detection of the vehicle 21 to be tested. The detection device 12 can detect an object at the preset position in a variety of ways. When an object is detected at the preset position, it is detected that the vehicle 21 to be tested has entered the preset position.

[0032] Continue to combine Figure 1 At least part of the image acquisition device 13 is disposed on the bracket 11. The image acquisition device 13 is used to acquire images of the doors and windows of the vehicle 21 to be tested after the vehicle 21 to be tested enters the preset position. The image processing device is connected to the image acquisition device 13. The image processing device is used to receive the image and process the image to obtain an image processing result that can reflect whether the doors and windows are closed.

[0033] Specifically, the image acquisition device 13 may include a camera device, and then the image of the door and window positions of the vehicle to be tested 21 is acquired through the camera device. Wherein, when the image acquisition device 13 acquires the image of the vehicle to be tested 21, the vehicle to be tested 21 may be in a stationary state, so as to acquire stable and appropriate images of the door and window positions. The images at the door and window positions can reflect whether the doors and windows of the vehicle are closed, so the processing result after the image processing device processes the image can reflect whether the doors and windows are closed. Wherein, an image processor is provided in the image processing device, and the image processor can process the image according to a preset image processing method, and then obtain an image processing result.

[0034] In summary, based on the vehicle door and window detection system 10 for the rain line provided by the present application, when the detection device 12 detects that the vehicle 21 to be tested enters the preset position before the rain line, the image acquisition device 13 can acquire the image of the door and window position of the vehicle 21 to be tested, and the image processing device further processes the image to obtain the image processing result, and then determines whether the vehicle's doors and windows are closed based on the image processing result. Therefore, based on this method, it is possible to automatically identify whether the vehicle's doors and windows are closed, thereby improving the recognition efficiency and accuracy.

[0035] In some specific embodiments, the vehicle door and window detection system 10 of the rain line includes a control device (not shown), which is connected to the image processing device and the transmission device 14 of the rain line, and the control device can receive the image processing result. When the control device determines based on the image processing result that any door and window of the vehicle to be tested 21 is not closed, the control device controls the transmission device 14 to stop transmitting the vehicle to be tested 21 to the rain room 22.

[0036] It should be understood that since the control device is connected to the image processing device and the conveying device 14 of the shower line, the control device can receive the image processing result obtained by the image processing device, and can control the conveying device 14 according to the judgment result. When it is judged that any door or window of the vehicle to be tested 21 is not closed, it means that the vehicle needs to close the door or window before it can be conveyed into the shower room 22. Therefore, the conveying device 14 is controlled to stop conveying the vehicle to be tested 21 into the shower room 22.

[0037] Figure 2 yes Figure 1 A top view of the structure shown, Figure 3 yes Figure 1 Side view of the structure shown.

[0038] Combination Figure 1-Figure 3 In some specific embodiments, the bracket 11 spans the vehicle conveying path so that its two ends are respectively supported on both sides of the vehicle conveying path, and the vehicle door and window detection system also includes a code reader 15, which is arranged at the part of the bracket 11 located directly above the vehicle conveying path.

[0039] At this time, the bracket 11 may include a crossbar portion 111 and a foot portion 112, wherein the foot portion 112 is arranged on both sides of the crossbar portion 111, and the foot portion 112 is used to support the crossbar portion 111. Wherein, when the bracket 11 crosses the vehicle transmission route, the crossbar portion 111 may cross the vehicle transmission route, and the foot portion 112 may be respectively arranged on both sides of the vehicle transmission route to support the crossbar portion 111. The code reader 15 may be an RFID (Radio Frequency Identification) type code reader 15, and a VIN number may be set on the vehicle. The code reader 15 may identify the VIN number of the vehicle, thereby obtaining the configuration information of the vehicle. Wherein, the configuration information of the vehicle may include information on the color, structure, etc. of the vehicle.

[0040] In some specific embodiments, the detection device 12 includes a photoelectric switch, which is disposed on the bracket 11 and is used to emit a detection light to detect whether the vehicle 21 to be tested is located at a preset position. Figure 1 , the detection device 12 marked in the figure can be a photoelectric switch. In combination with the above content, the photoelectric switch can be set on the support leg 112. The detection light emitted by the photoelectric switch can be emitted to a preset position, and then the object at the preset position is detected.

[0041] More specifically, in combination with the arrangement of the bracket 11 across the vehicle transmission route, the photoelectric switch includes a transmitter and a receiver, and the transmitter and the receiver are respectively arranged on the parts of the bracket 11 located on both sides of the vehicle transmission route. It should be understood that the accompanying drawings only show the transmitter arranged on one side of the vehicle transmission route. Figure 2 The photoelectric switch in can be a transmitter.

[0042] The transmitter is used to transmit the detection light, and the receiver is used to receive the detection light. When the receiver does not receive the detection light emitted by the transmitter, the vehicle to be tested 21 is located at the preset position. It should be understood that when the receiver does not receive the detection light emitted by the transmitter, it means that there is a vehicle to be tested 21 at the preset position, and the detection light is blocked by the vehicle to be tested 21, so the receiver cannot receive the detection light.

[0043] Combination Figure 1-Figure 3 In some specific embodiments, the image acquisition device 13 includes a door detection camera 131, a window detection camera 132, and a sunroof detection camera 133. The sunroof detection camera 133 is used to acquire an image at the sunroof position of the vehicle to be tested 21. The door detection camera 131 and the window detection camera 132 are used to acquire images at the door and window positions of the vehicle to be tested 21, respectively. At this time, different cameras are set to realize the detection of the sunroof, door, and window, which can improve the accuracy of the detection.

[0044] In combination with the arrangement of the bracket 11 across the vehicle transmission route, the sunroof detection camera 133 is arranged at the portion of the bracket 11 located directly above the vehicle transmission route, and the door detection camera 131 and the window detection camera 132 are both arranged at the portions of the bracket 11 located on both sides of the vehicle transmission route. That is, the sunroof detection camera 133 is arranged on the crossbar 111, and can be specifically arranged at the middle position of the crossbar 111. The door detection camera 131 is arranged on two supporting legs 112, and the window detection camera 132 is also arranged on two supporting legs 112. The door detection camera 131 and the window detection camera 132 can be arranged at the middle position of the supporting legs 112 in the vertical direction.

[0045] More specifically, the number of the door detection cameras 131 may be four, two of which are arranged on one side of the vehicle transmission route to detect the front door and rear door on one side of the vehicle to be tested 21; and two of which are arranged on the other side of the vehicle transmission route to detect the front door and rear door on the other side of the vehicle to be tested 21. Similarly, the number of the window detection cameras 132 may also be four, and the arrangement method is similar to that of the door detection cameras 131 to detect the front windows and rear windows on both sides of the vehicle to be tested 21.

[0046] Combination Figure 1 as well as Figure 2 In some specific embodiments, the vehicle door and window detection system further includes a lighting device 16 , which is disposed on the bracket 11 , and is used to work after the vehicle to be tested 21 enters a preset position to illuminate the door and window positions of the vehicle to be tested 21 .

[0047] Specifically, the light-emitting part of the lighting device 16 may be an LED light board, and the lighting device 16 is specifically arranged on the crossbar portion 111 of the bracket 11. The lighting device 16 may be arranged on both sides of the vehicle transmission line, thereby achieving relatively good lighting for the doors and windows on both sides of the test vehicle 21. It should be understood that the lighting of the lighting device 16 enables the image acquisition device 13 to acquire a better image, thereby facilitating the image processing device to obtain a processing result that can determine whether the doors and windows are closed.

[0048] Combination Figure 1-Figure 3In some specific embodiments, the vehicle door and window detection system further includes a control cabinet 17, which is arranged on the side of the bracket 11 away from the rain shower room 22 and on the side of the vehicle transmission route, and the control cabinet 17 is provided with a control device. Among them, the control device in the above embodiment is arranged in the control cabinet 17, and the control device can be connected to the image acquisition device 13, the detection device 12, etc. in addition to being connected to the image processing device, so as to realize control respectively. At this time, the number of control devices can be multiple, and the control of different devices can be realized respectively through multiple control devices.

[0049] Regarding the specific arrangement of the control cabinet 17, in some specific embodiments, the control cabinet 17 is also provided with an alarm light, which is used to light up an alarm when the control device determines that any door or window of the vehicle to be tested is not closed.

[0050] There may be two control cabinets 17, which are respectively arranged on both sides of the vehicle transmission route. In this case, both control cabinets 17 are provided with control devices, and the control devices in the two control cabinets 17 may be different control devices. In combination with the above content, by lighting the alarm light, the staff can find that the doors and windows of the vehicle 21 to be tested are not closed, so that the staff can respond.

[0051] Based on the structural framework described in the above embodiments, the process of detecting whether the doors and windows of the vehicle 21 to be tested are closed can be as follows:

[0052] The detection device 12 detects whether there is a vehicle 21 to be tested at a preset position. When the detection device 12 detects the vehicle 21 to be tested, it controls the lighting device 16 to turn on for lighting, and controls the door detection camera 131, the window detection camera 132 and the sunroof detection camera 133 to work to obtain images at the door and window positions.

[0053] The image processing device further receives the acquired image and processes the image. When the control device determines that any of the vehicle doors and windows are not closed according to the image processing result, it controls the conveying device 14 to stop conveying the vehicle 21 to be tested into the rain shower room 22, and controls the alarm light on the control cabinet 17 to light up to alarm, so that the staff can respond to it.

[0054] Among them, when the vehicle enters the preset position, the code reader 15 obtains the configuration information of the vehicle, and then in the subsequent process, the detection information of whether the vehicle's doors and windows are closed is bound to the vehicle, and the bound information can be further sent to the cloud for storage.

[0055] Figure 4 This is a schematic diagram of the structural framework of a convolutional neural network for image processing.

[0056] In some embodiments, the image processing device processes the image through a convolutional neural network. The specific processing method may be as follows:

[0057] First, the image is input to the input layer, followed by a convolution layer. After the first convolution layer performs a convolution operation on the input image, three feature maps are obtained. Each feature map corresponds to a convolution kernel. At this time, the data storage structure in the network model becomes (3, W, H).

[0058] Secondly, the first convolutional layer is followed by a downsampling layer (the downsampling layer is generally called a Pooling layer). The Pooling layer downsamples the three input feature maps (feature matrices) to obtain three smaller feature matrices (3, 2 / W, 2 / H).

[0059] Then, we come to the second convolution layer, and the convolution operation produces 5 feature maps (5, 2 / W, 2 / H).

[0060] Then, a Pooling layer is connected to downsample the five feature maps to obtain five smaller feature maps (5, 4 / W, 4 / H). Among them, two fully connected layers can be connected after the second Pooling layer (not shown). Each neuron in the first fully connected layer is fully connected to each neuron (each pixel) in the five feature maps of the previous layer, and the next fully connected layer is also fully connected to each neuron in the previous layer.

[0061] Finally, the last layer of the entire network is the output layer (Softmax layer), which calculates the fully connected feature vector to obtain the classification prediction value. Then, based on the classification prediction value, it is determined whether the car doors and windows are closed.

[0062] In summary, the vehicle door and window detection system 10 based on the rain shower line provided by the present application includes: a bracket 11, which is arranged on the vehicle transmission route of the rain shower line; a detection device 12, which is at least partially arranged on the bracket 11, and the detection device 12 is used to detect whether the vehicle 21 to be tested enters a preset position, and the preset position is located before the rain shower chamber 22; an image acquisition device 13, which is at least partially arranged on the bracket 11, and the image acquisition device 13 is used to acquire images of the doors and windows of the vehicle 21 to be tested after the vehicle 21 to be tested enters the preset position; an image processing device, which is connected to the image acquisition device 13, and the image processing device is used to receive images and process the images to obtain image processing results that can reflect whether the doors and windows are closed.

[0063] Therefore, based on the detection system and the corresponding detection method, the image is acquired by the image acquisition device 13, and then the image is processed by the image processing device, and it is possible to determine whether the vehicle is closed based on the image processing result. Based on this automatic detection method, the detection efficiency is high and the detection accuracy is high.

[0064] The above description is only an optional embodiment of the present application, and does not limit the patent scope of the present application. All equivalent structural changes made by using the contents of the present application specification and drawings under the scheme of the present application, or directly / indirectly used in other related technical fields are included in the patent protection scope of the present application.
