The top of the second hydraulic rod is fixedly connected with the moving plate.

[0008] When the vehicle is driving on the highway, for the ETC gantry scenario on the highway and when detecting the video automatic recognition and supplementary lighting equipment for highway vehicle license plates, generally, the vehicle needs to be driven to the vicinity of the detection area, and then the equipment is inspected manually. This inspection method is extremely inefficient and has potential safety hazards. During the inspection, it may affect the normal driving of vehicles on the highway. When this device is in use, it is pre-fixed to the seat through the fixing component and the limiting component. Then, by starting the first hydraulic rod of the telescopic component, it drives the connecting block to move, and the connecting block drives the placement frame to move for adjusting the position of the equipment. Then, by starting the second hydraulic rod to drive the moving plate to move, at this time, the broadband spectrometer, the illuminometer, and the imaging luminance meter can be pushed out to the set position for detection. For the ground brightness information, the imaging luminance meter is used to trigger the photographing data, and the ground brightness and the supplementary lighting area are analyzed. For the ground illuminance information, the data of the broadband spectrometer and the illuminometer are used to analyze and obtain the lateral supplementary lighting range, the longitudinal supplementary lighting range, and the lane center illuminance. For the chromaticity information of the supplementary light, the data of the broadband spectrometer are used to analyze and obtain the color rendering index and the color temperature. During the detection process, the vehicle driving speed is ≥80 km / h. Through the encoder + RTK positioning, the position relationship between the measurement data and the gantry is matched and bound. The various data required by the measurement index are analyzed and bound to the gantry through the GPS coordinates, forming a supplementary light detection database based on the gantry information. This detection method is not only efficient but also more accurate in detection.

[0009] As an alternative solution of the on-vehicle highway gantry camera supplementary light detection device and detection method described in the present invention, wherein: the fixing component includes a mounting frame, a first motor, and a first threaded shaft. A first motor is fixedly connected inside the mounting frame. The free end of the first motor is fixedly connected with a first threaded shaft.

[0010] When fixing this device, by placing the connecting frame at the bottom of the seat, placing the mounting frame above the seat, starting the first motor to drive the first threaded shaft to rotate, and the first threaded shaft drives the first threaded sleeve on the outside to move, thereby tightening the first tightening rope. Thus, under the action of the first tightening rope, the connecting frame, and the connecting piece, this device is fixed, facilitating the stable subsequent detection of this device.

[0013] As an alternative embodiment of the vehicle-mounted highway gantry camera fill light detection device and detection method of the present invention, wherein: a buffer seat is fixedly connected to the bottom of the mounting frame, and the bottom of the buffer seat is arranged in an arc shape.

[0014] The buffer seat provided at the bottom of the mounting frame is made of rubber material, which helps to fit with the seat and is used to ensure the stable fixation of the device.

[0015] As an alternative embodiment of the vehicle-mounted highway gantry camera fill light detection device and detection method of the present invention, wherein: the limiting component includes a fixed frame, a second motor and a second threaded shaft. The bottom of the fixed frame is fixedly connected to the fixing component. A second motor is fixedly connected inside the fixed frame. The free end of the second motor is fixedly connected to the second threaded shaft. A second threaded sleeve is spirally connected to the outside of the second threaded shaft. The other end of the second threaded sleeve is fixedly connected to a push plate. The other end of the push plate is fixedly connected to a second tightening rope, and both ends of the second tightening rope are fixedly connected to the connection frame;

[0016] Sliding grooves are formed on both sides of the second threaded sleeve, and the second threaded sleeve is slidably connected to the sliding block through the sliding grooves. The other end of the sliding block is fixedly connected to the fixed frame.

[0017] As an alternative embodiment of the vehicle-mounted highway gantry camera fill light detection device and detection method of the present invention, wherein: the rear side of the fixed frame is arranged in an arc shape, and the front side of the push plate is arranged in an arc shape.

[0018] After the fixing component is fixed, the second motor is started to drive the second threaded shaft to rotate. The second threaded shaft drives the second threaded sleeve to move. The movement of the second threaded sleeve drives the push plate to move. The push plate drives the second tightening rope to move. Thus, the second tightening rope can be in a tightened state, which helps to further fix the device. The provided sliding block can ensure the stable movement of the second threaded sleeve. Since the rear side of the fixed frame is arranged in an arc shape, it can stably and closely contact the backrest of the seat at this time, which helps the second tightening rope to be tightened and ensures the fixation of the device.

[0019] As an alternative embodiment of the vehicle-mounted highway gantry camera fill light detection device and detection method of the present invention, the detection steps are as follows:

[0020] Step 1: First, place this device on the co-pilot seat. Then, place the connection frame at the bottom of the co-pilot seat. Next, the fixing component is located on the co-pilot seat. By activating the fixing component, it can ensure the fixing purpose under the action of the connection frame, connecting piece, and fixing component;

[0021] Step 2: By activating the limiting component, it can be used to further fix this device, achieving the purpose of reinforcement;

[0022] Step 3: By activating the telescopic component, the broadband spectrometer, illuminometer, and imaging luminance meter inside the telescopic component can be horizontally moved at the co-pilot seat position for adjusting the position to facilitate subsequent detection;

[0023] Step 4: After installing the broadband spectrometer, illuminometer, and imaging luminance meter, move the telescopic component to the working position. Use the broadband spectrometer to calibrate the optical attenuation coefficient of the vehicle windshield, and enter the coefficient into the broadband spectrometer, illuminometer, and imaging luminance meter for correction;

[0024] Step 5: Before detection, move the telescopic component to the working position. Start and run the broadband spectrometer, illuminometer, and imaging luminance meter devices. Use the encoder pulse as the trigger source to collect data, and transmit the collected data back to the central controller;

[0025] Step 6: After passing directly under the gantry, the acquisition ends by being triggered by the lidar installed on the vehicle roof. The central controller obtains the acquisition end signal, measures the mileage according to the encoder, and can retrieve the detection data at a specified distance forward according to the detection requirements to form an optical dataset in front of the gantry;

[0026] Step 7: The central controller analyzes the dataset. For the ground brightness information, use the imaging luminance meter to trigger the photographed data, and analyze to obtain the ground brightness and fill light area. For the ground illuminance information, use the broadband spectrometer and illuminometer data to analyze to obtain the horizontal fill light range, depth fill light range, and lane center illuminance. For the chromaticity information of the fill light, use the broadband spectrometer data to analyze to obtain the color rendering index and color temperature. Form a fill light detection dataset;

[0027] Step 8: Compare the high-precision GPS coordinates transmitted back by the RTK installed on the vehicle roof with the longitude and latitude coordinates of the gantry in the database for matching. Bind the detection dataset, optical dataset with the gantry number and the lane number where it is located to form a fill light detection database based on gantry information.

[0028] Compared with the prior art, the beneficial effects of the present invention are:

[0029] In the present invention, a broadband spectrometer and an imaging luminance meter are provided. For ground luminance information, the imaging luminance meter is used to trigger photographing data, and the ground luminance, the supplementary lighting area are analyzed and obtained. For ground illuminance information, the broadband spectrometer and illuminometer data are used to analyze and obtain the lateral supplementary lighting range, the longitudinal supplementary lighting range, and the lane center illuminance. For the chromaticity information of the supplementary light, the broadband spectrometer data is used to analyze and obtain the color rendering index and the color temperature. During the detection process, the vehicle speed is ≥ 80 km / h. Through the encoder + RTK positioning, the positional relationship between the measurement data and the gantry is matched and bound. The various data required by the measurement indicators are analyzed and bound to the gantry through GPS coordinates, forming a supplementary light detection database based on the gantry information. This detection method is not only fast in efficiency but also more accurate in detection.

[0030] When fixing the present device, the connecting frame is sleeved on the bottom of the seat, and then the fixing component is placed above the seat. By starting the first motor to drive the first threaded shaft to rotate, the first threaded shaft drives the first threaded sleeve to move, the first threaded sleeve drives the pressing plate at the top to move, and the pressing plate drives the first tightening rope to move upward. At this time, it can be ensured that the first tightening rope is tightly squeezed, and further ensure that under the action of the first tightening rope, the connecting piece and the connecting frame, the device is tightly connected to the seat, ensuring the subsequent stable detection of the light.

[0031] After completing the longitudinal fixation of the device, the second motor is set to drive the second threaded shaft to rotate, and the second threaded shaft drives the second threaded sleeve to move. Under the action of the sliding block, it is ensured that the second threaded sleeve drives the push plate to move, so as to horizontally fix the second tightening rope to the co-pilot seat, further ensuring the stability of the device.

[0032] After the fixation is completed, by starting the first hydraulic rod to drive the connecting block to move, the placement frame moves to adjust the position of the device. By starting the second hydraulic rod to drive the moving plate to move, the moving plate drives the broadband spectrometer and the imaging luminance meter to move upward.
