Fig. 2 is a block diagram of a system for measuring a vehicle by a vehicle measuring device, which includes a measuring stand 100, two wheel image capturing

assemblies

200a,200b, a processor 300, and a calibration element 400.

The two wheel

image capturing assemblies

200a,200b, the processor 300 and the calibration element 400 are all carried on the measurement mount 100.

In the embodiment of the present application, a state in which the vehicle measurement device is normally used is described, in which a direction parallel to a ground surface on which the vehicle measurement device is located is taken as a horizontal direction, and a direction perpendicular to the ground surface on which the vehicle measurement device is located is taken as a vertical direction, where the horizontal direction includes a horizontal lateral direction and a horizontal longitudinal direction, and the horizontal lateral direction and the horizontal longitudinal direction are perpendicular to each other. In the embodiment of the present application, the horizontal transverse direction is specifically a direction parallel to the vehicle head, and the horizontal longitudinal direction is a direction parallel to the vehicle centerline.

The measurement stand 100 includes a base 10, a stand assembly 20, a mounting beam assembly 30, and a rotation mechanism 40. The stand assembly 20 comprises a stand 21, the stand 21 extends along a substantially vertical direction, and the stand 21 is mounted on the base 10; the mounting beam assembly 30 includes a support frame 31 and a mounting beam 32, the support frame 31 is connected to the upright frame 21, the support frame 31 can rotate relative to the upright frame 21 around a rotation axis O through a rotation mechanism 40, the rotation axis O is horizontal, that is, the rotation axis O is parallel to the ground where the base 10 is located. The mounting beam 32 is connected to an end of the support frame 31 remote from the rotation axis O.

The installation comprises fixed installation such as welding installation and the like, and also comprises detachable installation.

The axis of rotation O is perpendicular to the mounting beam 32 or parallel to the mounting beam 32.

In the embodiment of the present application, the mounting beam 32 is a long strip structure, that is, the length of the mounting beam 32 is greater than the width, and the central line L of the supporting frame 31 passes through the central point a of the mounting beam 32, so as to ensure that two ends of the central point a of the mounting beam 32 are symmetrical. In the embodiment of the present application, when the mounting beam 32 is in the horizontal direction, the longitudinal direction of the mounting beam 32 is the horizontal transverse direction, and the direction perpendicular to the longitudinal direction of the mounting beam 32 is the horizontal longitudinal direction.

For the direction of the rotation axis O in fig. 3 being horizontal and longitudinal, i.e. the direction of the rotation axis O is perpendicular to the length direction of the mounting beam 32, the supporting frame 31 in the mounting beam assembly 30 pivots clockwise or counterclockwise relative to the stand assembly 20 about the rotation axis O, thereby changing the position of the mounting beam 32.

In other embodiments, as shown in fig. 6, the direction of the rotation axis O may be horizontal and transverse, i.e. the direction of the rotation axis O is parallel to the length direction of the mounting beam 32, and the supporting member 31 in the mounting beam assembly 30 can rotate forwards or backwards around the rotation axis O, so as to fold the mounting beam 32 relative to the stand assembly, thereby changing the position of the mounting beam 32.

The two wheel

image capturing assemblies

200a,200b are transversely disposed at two ends of the mounting beam 32 at intervals, so that when the measuring bracket 100 is placed at a position corresponding to the vehicle, the field of view of the two wheel

image capturing assemblies

200a,200b respectively covers the areas where the wheels on two sides of the vehicle are located, and the wheel image capturing assemblies are used for capturing image data of objects in the areas where the wheels are located. Since it is necessary to cover the area where the wheels on both sides of the vehicle are located, there is a requirement for the height of the wheel image capturing assembly, and the mounting beam 32 can be placed above the stand assembly 20, i.e. the mounting beam 32 is above the support frame 31, to meet the capturing requirements (as shown in fig. 1).

The processor 300 is electrically connected to the two wheel

image capturing assemblies

200a,200b to receive data captured by the two wheel

image capturing assemblies

200a,200b, and measures the wheel state of the vehicle according to the data captured by the two wheel

image capturing assemblies

200a, 200b.

In the present embodiment, the measurement stand 100 is placed in a position relative to the vehicle, which means that the measurement stand is placed in a specified or preset position relative to the vehicle, or the measurement stand 100 is placed in an arbitrary position within a specified range relative to the vehicle. In order to be able to position the calibration elements or the wheel image capture assemblies accurately, and thus not affect the calibration accuracy or the accuracy of the captured images, the measurement mount 100 carrying the calibration elements or the wheel image capture assemblies is usually specified in terms of its position relative to the vehicle, which specification may be recorded on a user operating manual, by which the user may step-by-step perform an accurate positioning of the measurement mount, or which specification may be implemented in terms of an executable program by a processor, which may output control instructions to drive the measurement mount to automatically position to a specified or preset position. The calibration element or the wheel image capturing assembly may be fixedly or movably mounted to the measuring support 100, and if the calibration element 400 or the wheel image capturing assembly is movably mounted to the measuring support 100, the moving mechanism between the wheel image capturing assembly and the measuring support 100 may be adjusted to precisely position the wheel image capturing assembly to a predetermined position. Alternatively, if the calibration algorithm or the wheel detection algorithm allows a certain error, the measurement mount 100 may be placed within a specified range with respect to the vehicle, and if the measurement mount 100 is within the specified range, the positioning error thereof may be calibrated by a subsequent calibration algorithm or the wheel detection algorithm.

In the present embodiment, the measuring stand 100 is placed in front of the vehicle.

It will be appreciated that in other embodiments the measurement stand is positioned to the side or rear of the vehicle, depending on the actual requirements. The wheel can be located in a space range near the wheel, if a target carrying a pattern is installed on the wheel in some scenes, the view range of the wheel image acquisition assembly needs to cover the target, the processor 300 is combined to identify the wheel to be positioned through the pattern carried on the identification target, the wheel can also be located in a space range occupied by the wheel, and if the wheel image acquisition assembly only needs to acquire the image of the wheel in other scenes, the processor 300 is combined to identify the wheel image to position the wheel.

The wheel image capture assembly may be static with respect to the captured image. For example, the wheel image capturing assembly processes the captured static images of the wheels of the vehicle in a static state, i.e., without any positional movement of the vehicle relative to the ground.

The wheel image capture assembly may also be dynamic with respect to the captured images. For example, the wheel image capturing assembly processes the captured dynamic images of the wheels of the vehicle in a dynamic state, such as during a certain range of vehicle motion.

The lateral separation distance between the two wheel

image capturing assemblies

200a,200b may be determined based on the width of the vehicle. In some embodiments, the lateral separation distance between the two wheel

image capture assemblies

200a,200b is adjustable, or alternatively, the lateral separation distance between the two wheel image capture assemblies is fixed.

In other embodiments, the two wheel

image capturing assemblies

200a,200b may be laterally spaced by other means, for example, the support frame may have two symmetrical arms, one end of each arm of the two arms is connected to the support frame, and the other end of each arm is mounted with the wheel image capturing assemblies. The implementation manner of the lateral spacing of the two wheel image capturing assemblies in the embodiment of the present application is not limited in the present application.

image capturing assemblies

200a,200b are detachably mounted to the mounting beam 32, that is, the two wheel

image capturing assemblies

200a,200b may exist as an accessory for the measuring support 100, when only the ADAS calibration function needs to be implemented, the wheel image capturing assemblies do not need to be mounted, if wheel dynamic parameters need to be calculated, or when wheels of a vehicle need to be detected, the two wheel

image capturing assemblies

200a,200b are mounted to the mounting beam 32, and the two wheel

image capturing assemblies

200a,200b may be fixedly or movably mounted to the mounting beam 32. In order to ensure that the mounting accuracy of the wheel image acquisition assembly does not affect the calculation of the wheel state parameters, the mounting position of the wheel image acquisition assembly can be identified on the mounting beam 32, or a special mounting mode is designed, so that the wheel image acquisition assembly can be mounted on the preset position of the mounting beam 32.

The wheel image acquisition assembly can be a device only having an image acquisition function, such as an image acquisition sensor, a camera or a video camera, and the like, and can also be a device having an image acquisition function and capable of processing images, and can perform processing such as format conversion, storage, pixel calculation, cutting or assignment and the like on the images.

In the above implementation, the mounting beam 32 can be adjusted in height relative to the support frame 31; or the mounting beam assembly 30 may be moved relative to the riser assembly 20 to adjust the height of the mounting beam 32; or the mounting beam 32 is fixed relative to the height of the stand assembly 20 or the support frame 31, and the wheel image acquisition assembly can rotate relative to the mounting beam 32 so as to adjust the visual field range of the wheel image acquisition assembly; through any one of the above modes, the visual field range of the wheel image acquisition assembly can be adjusted to cover the areas where the wheels on the two sides of the vehicle are located.

For the mounting beam 32 to be height adjustable relative to the support frame 31, a track may be provided on the support frame 31 to guide the mounting beam 32 for movement relative to the support 31.

With respect to the movement of mounting beam assembly 30 relative to riser assembly 20, this can be accomplished in conjunction with the related description below.

For the wheel image capture assemblies to rotate relative to the mounting beam, the processor 300 may control the wheel image capture assemblies at both ends to rotate synchronously. In this embodiment, the processor 300 may perform image processing and related calculation to determine the wheel state parameters, or the processor 300 may transmit the acquired image data to an external device, and perform further processing by the external device to determine the wheel state parameters.

The processor 300 is electrically connected to the two wheel

image capturing assemblies

200a,200b, respectively, and if the processor is connected to the two wheel

image capturing assemblies

200a,200b by wire or wirelessly, the processor 300 is configured to measure the wheel states of the vehicle according to the data captured by the two wheel

image capturing assemblies

200a,200b, so as to position the wheels, including comprehensively measuring various positioning parameters of the wheels, such as camber angle, toe-in angle, and the like; or whether the detection wheel needs to be positioned or not can be determined by a simple algorithm, and only whether the current state of the wheel needs to be comprehensively detected or not can be determined, that is, the positioning of the wheel is further performed.

In some embodiments, the vehicle measurement device may further include an output 500. The output device 500 is electrically connected to the processor 300 and is used for prompting a user to output a result of the processor 500, and the output device may include at least one of a display screen, a sounder, and the like.

Wherein the handler 300 may be provided to the mounting beam 32. Mounting beam 32 may also be provided with mounting slots for receiving processor 300 and its transmission lines for electrical connection with the wheel image capture assembly. Of course, the processor 300 may be housed in the base 10 or the stand assembly 20, in which case the processor is wirelessly connected to the wheel image capturing assembly, or the processor 300, the output device 500 and the transmission line are all disposed in an external component. The external components are attached to the outer surface of the base 10, the riser assembly 20 or the mounting beam assembly 30. It is understood that the processor 300 may be wirelessly connected to the wheel image capture assembly when an external component is attached to the stand assembly 20 or the base 10. It is understood that the measurement support 100 may further be provided with a power supply device for supplying power to the wheel image collecting assembly, the processor, the output device, and the like, wherein the power supply device includes a battery, and the battery may be a zinc-manganese battery, an alkaline battery, a nickel-cadmium battery, a lithium battery, or a rechargeable storage battery. Alternatively, the power supply device is detachably mounted to the measuring stand, or the power supply device is fixedly mounted to the measuring stand.

The calibration element 400 may be carried by the mounting beam assembly 30 for calibrating a driving assistance system of the vehicle. In the present embodiment, the calibration element 400 is carried by the mounting beam 32 when the support frame is rotated around the rotation axis O to a position where the mounting beam 32 is below the support frame 31, as shown in fig. 4, that is, the mounting beam 32 is used in a vehicle calibration scenario.

The vehicle driving system can be divided into an adaptive cruise system, a blind spot system, a vehicle deviation warning system and the like according to different functions. The self-adaptive cruise system mainly comprises radars, the radars of the self-adaptive cruise system can be single radars or double radars, the single radars are generally arranged in the middle of the head of the vehicle, and the double radars are generally arranged on two sides of the head of the vehicle. The radar in the adaptive cruise system may be calibrated by an adaptive cruise system calibration element, which may be a radar calibration board (for reflecting waves emitted by the radar), a radar calibration box, a corner reflector, or other radar calibration elements. The blind spot system mainly comprises a radar, the radar of the blind spot system is generally arranged at the tail of the vehicle, the blind spot system can be calibrated through a calibration element of the blind spot detection system, and the calibration element of the blind spot detection system can be a multi-common-thunder generator, namely a blind spot box, a radar calibration box and the like. The vehicle deviation warning system mainly comprises a camera on a vehicle window of the vehicle, and the vehicle deviation warning system can be calibrated through the pattern plate.

Optionally, the mounting beam 32 may be detachably mounted to the support frame 31, and the mounting beam 32 may be replaced by multiple beams to adapt to different application scenarios, for example, a first mounting beam is fixedly connected with the wheel image capturing assembly, a second mounting beam is used for mounting the calibration element, the first mounting beam or the second mounting beam is detachably mounted to the support frame, for a wheel positioning scenario, the first mounting beam may be mounted to the support frame, and for a calibration vehicle scenario, the second mounting beam may be mounted to the support frame. Because the first mounting beam is usually arranged at the upper part of the stand assembly (as shown in fig. 1) and needs to be made of a light-weight material, and the second mounting beam is usually made of a material with certain weight or rigidity in order to ensure that the calibration element is supported without deformation, the mounting beam can be better suitable for corresponding application scenes; alternatively, the mounting beam may be simultaneously connected with the wheel image acquisition assembly and may carry the calibration element.

Further, in any of the above implementations, the measurement bracket may further include a mount, a sliding rail is disposed on the mounting beam 32 along a length direction of the mounting beam 32, the mount is slidably connected to the sliding rail, and the calibration element 400 is mounted on the mounting beam 32 through the mount, so that the calibration element 400 can slide relative to the mounting beam 32 through the sliding rail to adapt to different devices to be calibrated, where the devices to be calibrated may be sensors of an adaptive cruise system, for example: sensors for night vision systems, sensors for vehicle deviation warning systems, etc., while the position of the device to be calibrated on the vehicle varies from system to system, for example: the sensors of the night vision system are generally located at positions where the vehicle head deviates from the middle point, and the sensors of the adaptive cruise system are generally located on two sides of the vehicle head. In some embodiments, the mounting beam 32 can rotate relative to the supporting frame 31 to adjust the pitch angle of the mounting beam 32, so that the surface of the calibration element on the mounting beam 32 facing the vehicle is perpendicular to the ground, thereby ensuring the positioning accuracy of the calibration element and further ensuring the calibration accuracy of the vehicle.

Rotation of the mounting beam 32 relative to the support frame 31 may be effected by any conventional technique and the mechanism for driving rotation of the mounting beam relative to the support frame may be: hinge mechanism, connecting rod type rotating mechanism, crank type rotating mechanism, etc.

It can be understood that the mounting beam is further provided with a locking mechanism for keeping the mounting beam and the support frame relatively fixed when the mounting beam is rotated to a state that the surface of the calibration element on the mounting beam facing the vehicle is perpendicular to the ground on which the vehicle is located.

The locking mechanism can be a friction plate, and the friction plate can be used for fixing the mounting beam and the support frame at a required position.

In this embodiment, the supporting frame 31 is a V-shaped structure, and the supporting frame 31 and the mounting beam 32 enclose to form a triangular structure, so that the mounting beam assembly 30 can maintain a relatively stable state in the moving or rotating process.

In other embodiments, the support frame may also be in an "i" shape or a "U" shape, and the like, which is not limited in this application.

In the first instance, when the support bracket 31 is at the upper end of the stand assembly 20, as shown in fig. 1 for the position of the support bracket 31, i.e., the support bracket 31 is used in a wheel alignment scenario, the support bracket 31 is fixed relative to the stand assembly 20, i.e., the support bracket 31 cannot move in a vertical direction relative to the stand assembly 20. In this scenario, the stand assembly 20 may further be provided with an auxiliary support portion for assisting the support frame 31 to support the mounting beam 32, so as to share the weight of the mounting beam 31 and ensure that the mounting beam 32 is horizontally and horizontally disposed.

After the supporting frame 31 is rotated from the position shown in fig. 1 to the position shown in fig. 4 through the rotating mechanism 40, the connection relationship between the supporting frame 31 and the rotating mechanism 40 can be released, and the supporting frame 31 and the driving mechanism 22 are connected, so that the driving mechanism 22 can drive the supporting frame 31 to move in the vertical direction relative to the stand assembly 20, for example, the rotating mechanism is a clutch.

In this embodiment, the driving mechanism 22 includes a driving source 221 and a transmission assembly, the driving source 221 is connected to the mounting beam assembly 30 through the transmission assembly, and the driving source 221 is used for driving the mounting beam assembly 30 to move relative to the vertical frame 21.

In the first case, a rotation driving source is omitted, for example, the driving source drives the mounting beam assembly to ascend and descend through a gear transmission mechanism, and simultaneously drives the support frame to rotate around the rotation axis O, the gear transmission mechanism comprises a first bevel gear and a second bevel gear, the first bevel gear is meshed with the second bevel gear, the central axis of the first bevel gear is perpendicular to the central axis of the second bevel gear, the central axis of the second bevel gear is coaxial with the rotation axis, the screw rod is coaxially connected to the first bevel gear, the support frame is connected to the second bevel gear, and the driving source is connected to the screw rod, so that when the driving source drives the screw rod to rotate, the first bevel gear and the second bevel gear are driven to rotate together, and the mounting beam assembly rotates around the rotation axis.
