Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an aiming apparatus for a vehicle lamp,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an aiming apparatus for a vehicle lamp, and more particularly, to an aiming apparatus for a vehicle lamp that performs aiming of a headlamp and an operation method thereof.

In general, the vehicle is equipped with various lamps having a lighting function for easily confirming an object located in the vicinity of the vehicle at the time of night driving and a signal function for notifying other vehicles or road users of the running condition of the vehicle. It is stipulated by law as to the installation standards and specifications so that the functions are fully exercised.

For example, a head lamp, a fog lamp, and the like are intended for illumination, and a turn signal lamp, a tail lamp, a brake lamp, and a side marker are signals.

Among them, the headlamp plays a very important role in securing the front view of the driver when driving at night, thereby ensuring safe driving.

In order to prevent the driver of the opposed vehicle from glare, the head lamp should be appropriately adjusted by using a high beam pattern or a low beam pattern in order to prevent glare from occurring. In addition, It is required to carry out the aiming which changes the irradiation direction differently from the original setting or adjusts the irradiation direction originally set according to the traveling environment.

The aiming can be performed by rotating at least one aiming point in the up, down, left, and right directions based on a predetermined fixed reference point formed in the head lamp to adjust the direction of light irradiation.

However, since it is difficult for the driver to manually adjust the angle of the head lamp by operating the aiming screw, the angle of the head lamp is generally adjusted through the operator of the workshop.

Therefore, there is a demand for a method of automatically performing the aiming of a headlamp without going through a worker at a workshop.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described with reference to the drawings for explaining an aiming apparatus of a lamp for a vehicle and an operation method thereof according to embodiments of the present invention.

FIG. 1 is a block diagram of an aiming device of a lamp for a vehicle according to an embodiment of the present invention, and FIG. 2 is a block diagram of a control module according to an embodiment of the present invention.

1, the aiming apparatus 1 for a vehicle lamp according to an embodiment of the present invention includes an image acquisition module 100, an aiming point setting module 200, a control module 300, And an execution module 400.

The image acquisition module 100 acquires a first image and a second image of a beam pattern irradiated on a wall surface, respectively, when the vehicle is at a different position from a wall surface positioned in front of the vehicle. Here, the obtained first image and second image are stored in the control module 300.

3, the image acquisition module 100 irradiates the light of the headlamp 30 when the vehicle 10 is positioned at the first distance 40 from the wall surface 2, 2 to obtain a first image of the beam pattern. When the vehicle 10 moves a predetermined distance toward the wall surface 2 and is positioned at the second distance 40 'from the wall surface 2, the light of the head lamp 30 is irradiated, And acquires a second image for the beam pattern. Here, the distance between the vehicle 10 and the wall surface 2 can be understood to be shorter than the first distance 40 by the second distance 40 '.

The image acquisition module 100 may be understood to be included in the camera 20 and the camera 20 may be installed in the center of the front of the vehicle 10, But the present invention is not limited thereto. The installation position of the camera 20 may be variously changed depending on the application and needs. The camera 20 is preferably a normal visible light camera, but it does not exclude an infrared camera or other types of cameras. The camera 20 may be implemented with a light-capturing sensor such as a CCD (Charge Coupled Device), a CMOS (complementary metal-oxide semiconductor), or the like.

The aiming point setting module 200 sets a first aiming point in the first image acquired by the image acquiring module 100 and sets the first aiming point in the second image acquired by the image acquiring module 100. [ To obtain a second aiming point corresponding to the second aving point.

In the embodiment of the present invention, the aiming point setting module 200 sets any point on the cutoff line of the beam pattern included respectively in the first image and the second image to the first aiming point, The aiming point setting module 200 calculates a cutoff line detection value for detecting a cutoff line of the beam pattern. For example, (Not shown).

4, the cut-off line sensing unit 210 converts a first image and a second image including a beam pattern of the head lamp 30 obtained from the image acquisition module 100 into a gray pattern, As shown in FIG. Then, the contour of the detected beam pattern is Hough transformed to detect the cutoff line 5. [

As shown in Figs. 5A and 5B, the aiming point setting module 200 sets the aiming point setting module 200 at a predetermined position near the cutoff line 5 of the first image 50, (6 'and 7') in the second image 50 'and second amming points 6' and 7 'at points corresponding to the first aiming points 6 and 7 in the second image 50'.

5 (a) is a view showing the left / right light irradiation direction of the head lamp 30 on the basis of the first image 50 when the vehicle 10 is located at the first distance 40 from the wall surface 2 5B shows the first image 50 'when the vehicle 10 is positioned at the second distance 40' from the wall surface 2, and FIG. 5B shows the first image 50 ' ≪ / RTI > in FIG. 1). Hereinafter, the first aiming point 6 and the second aiming point 6 ', which represent the left light irradiation direction of the head lamp 30, will be described.

On the other hand, in the embodiment of the present invention, an arbitrary point in the vicinity of the cutoff line 5 is set as an aiming point. However, the present invention is not limited to this, .

When the control module 300 displays the first aiming point 6 and the second aiming point 6 'as the top view viewed from above the vehicle 10, the first aiming point 6' The horizontal adjustment angle of the head lamp 30 of the vehicle 10 is calculated using the first and second aiming points 6 and 6 '. Hereinafter, a process of the control module 300 displaying the first aiming point 6 and the second aiming point 6 'as a top view will be described in detail.

First, when the aiming point setting module 200 sets the first aiming point 6 in the first image 50 acquired from the image acquiring module 100 as shown in FIG. 6, the control module 300 connects the predetermined point of the camera 20 mounted on the vehicle 10 and the first aiming point 6 on the straight line 60. [ At this time, since the angle of view of the camera 20 and the center axis 90 of the vehicle 10 are predetermined, the control module 300 determines the angle between the center axis 90 of the vehicle 10 and the straight line 60 To calculate the position of the first aiming point 6 on the top view. In addition, the position of the second aiming point 6 'on the top view can also be obtained in a manner similar to the first aiming point 6.

The control module 300 also calculates the distance between the vehicle 10 and the wall surface 2 based on the longitudinal distance on the top view between the first aiming point 6 and the second aiming point 6 ' And calculates the vertical adjustment angle of the head lamp 30 of the vehicle 10 using the calculated distance. Here, the distance between the vehicle 10 and the wall surface 2 means the distance between the camera 20 mounted on the vehicle 10 and the wall surface 2. The control module 300 includes a travel distance sensing unit 310, a steering angle sensing unit 320, a storage unit 330, and an ECU 340.

The travel distance sensing unit 310 may sense the distance traveled by the vehicle 10. In other words, the moving distance sensing unit 310 is configured to move the vehicle 10 until the vehicle 10 is positioned at the second distance 40 'from when the vehicle 10 is positioned at the first distance 40 from the wall surface 2 A distance d between the first distance 40 and the second distance 40 'can be detected. Here, the distance d that the vehicle has moved can be detected by detecting the driving information including the steering angle information, the distance information, and the speed information of the vehicle provided from the ECU, the TCU, the wheel sensor, or the steering angle sensor.

The steering angle sensing unit 320 detects the steering angle of the vehicle 10 by detecting the steering angle of the steering wheel or the wheel of the vehicle 10.

7, when the vehicle 10 moves from the first distance 40 to the second distance 40 ', the steering angle sensing unit 320 detects the steering angle of the steering wheel or the wheel, 10). Here, the steering angle is used to make more accurate aiming in performing the aiming of the headlamp 30 based on the horizontal / vertical adjustment angle of the headlamp 30, do.

The storage unit 330 stores the first image 50 and the second image 50 'obtained from the image acquisition module 100 and the first image point 6 and the second image point 6' . The storage unit 340 may be a cache, a RAM, an SRAM, a DRAM, a ROM, a PROM, an EPROM, an EEPROM, a flash memory, and a hard disk drive.

When the ECU 340 displays the first aiming point 6 and the second aiming point 6 'in the top view viewed from above the vehicle 10, the first aiming point 6 and the second aiming point 6' 2 between the first aiming point 6 and the second aiming point 6 ', and calculates the horizontal adjustment angle of the headlamp 30 of the vehicle 10 using the second aiming point 6' The distance between the vehicle 10 and the wall surface 2 is calculated based on the longitudinal distance on the vehicle. Here, the ECU 340 can be understood as a processor used in the vehicle 10. [

The ECU 340 connects the predetermined point of the camera 20 and the first aiming point 6 on the top view with a straight line 60 as shown in Fig. 8 (a) And the second aiming point 6 'on the top view by a straight line 60'. Next, a predetermined point of the head lamp 30 is connected to the first aiming point 6 by a straight line 70, and the lateral offset between the second aiming point 6 'and the straight line 70 is set to . Here, the first aiming point 6 and the second aiming point 6 'are represented by one point on the straight lines 60 and 60', but this is merely an example for facilitating understanding of the present invention, But it is not limited thereto and can be located anywhere on straight lines 60 and 60 '.

As shown in FIG. 8 (b), the ECU 340 is configured to shift the first aiming point 6 and the second aiming point 6 'along a straight line 60, 60' Then connects the predetermined point of the head lamp 30 with the first aiming point 6 on a straight line 70 and calculates the transverse offset between the second aiming point 6 'and the straight line 70 Repeat the process. Here, the first aiming point 6 and the second aiming point 6 'are shifted while keeping the longitudinal spacing the same.

As shown in FIG. 8 (c), the ECU 340 finds the shortest transverse offset between the second aiming point 6 'and the straight line 70, It is possible to detect the humming point 6. Here, the distance between the first aiming point 6 detected in FIG. 8 (c) and a predetermined point of the headlamp 30 is the distance between the vehicle 10 and the wall surface 2, that is, the distance between the first distance 40 ).

In other words, a predetermined point, the first aiming point 6, and the second aiming point 6 'of the headlamp 30, when the headlamp 30 is properly aimed (i.e., in an ideal case) And is positioned on one straight line. On the basis of this principle, if the lateral offset of the straight line 70 and the second aiming point 6 'from the predetermined point of the headlamp 30 and the first aiming point 6 is the shortest, The distance between the first aiming point 6 of the vehicle 10 and the vehicle 10 can be estimated as the distance between the vehicle 10 and the wall surface 2.

In the embodiment of the present invention, for example, when the vehicle 10 has moved 5 m, the longitudinal distance between the first aiming point 6 and the second aiming point 6 'is understood to be 5 m . Thus, the distance from the first aiming point 6 to the vehicle 10 can be calculated since it is shifted at intervals of 5 m in the top view.

When the first aiming point 6 and the second aiming point 6 'are shifted once as shown in Fig. 8 (c), the second aiming point 6' is shifted to the head lamp 30 The distance between the head lamp 30 and the first aiming point 6 can be calculated as 10 m. Since the distance between the head lamp 30 and the camera 20 is known in the present invention, the distance between the vehicle 10 and the first aiming point 6 (i.e., the distance between the vehicle 10 and the wall surface 2) Can be calculated.

The ECU 340 calculates the angle between the straight line 80 with respect to the axis of the vehicle 10 and the straight line 70 connected with the detected first aiming point 6 as shown in Figure 8 (c) (E.g., the horizontal adjustment angle of the headlamp), and provides the calculated angle (e.g., 0.5 DEG) to the aiming execution module 400. [

In addition, the ECU 350 can calculate the vertical adjustment angle of the head lamp 30 based on the distance between the calculated vehicle 10 and the wall surface 2.

9 (a) and 9 (b), D is the distance from the wall surface 2 to the camera 20, f is the focal length of the camera 20, 30 and the installation height of the distance camera (20), H _L is the head lamp (30), H _c is the first aiming point the mounting height of the camera 20, in the s is the center of the image sensor ( 6 in the vertical direction.

The distance h1 between the height position of the camera 20 and the first aiming point 6 can be calculated from the following equation (1).

[Equation 1]

h1 = D * f / s

s can be calculated again as x * c / V, where V is the total number of pixels in the longitudinal direction of the first image 50 and x is the first aiming point 6 at the center of the first image 50, , And c represents the physical size (height) of the image sensor.

On the other hand, the distance h2 between the ground and the first aiming point 6 can be calculated from the following equation (2).

&Quot; (2) "

h2 = H _c - h1

Theta value between the vertical position of the head lamp 30 and the first aiming point 6 can be calculated from the following equation (3). Here, the vertical irradiation angle of the head lamp 30 is adjusted through the calculated? Value (i.e., the vertical adjustment angle of the lamp 30).

Theta value between the vertical position of the head lamp 30 and the first aiming point 6 can be calculated from the following equation (3).

 &Quot; (3) "

= tan ^-1 = H _L - h2 / (DW)

That is, the calculated? Value is the vertical adjustment angle of the head lamp 30, and adjusts the vertical irradiation angle of the head lamp 30 through the? Value. Here, the ECU 340 provides the calculated vertical adjustment angle of the head lamp 30 to the aiming execution module 400. [

Meanwhile, the case of calculating the adjustment angle with respect to the vertical irradiation angle of the head lamp 30 by using the calculated? Value has been described as an example, but this is merely an example for facilitating the understanding of the present invention. When the distance D between the vehicle 10 and the wall surface 2 calculated by the ECU 340 is smaller than the distance D between the vehicle 10 and the wall surface 2 calculated by the ECU 340, The vertical angle of the corresponding head lamp 30 may be extracted to obtain the adjustment angle with respect to the vertical irradiation angle of the head lamp 30. [

In addition, the ECU 340 adjusts the steering angle so that the vehicle 10 is linearly moved based on the steering angle sensed by the steering angle sensing unit 320.

That is, in the present invention, adjusting the steering angle is for performing more accurate aiming at the time of performing the aiming of the headlamp 30. In the present invention, adjusting the steering angle is performed when the ECU 340 determines that the headlamp 30 And the distance between the vehicle 10 and the wall surface 2. However, the present invention is not limited thereto, and the present invention is not limited to this, 30). ≪ / RTI >

Meanwhile, in the present invention, when the steering angle sensed by the steering angle sensing unit 320 is an angle at which the vehicle 10 is linearly moved, no separate steering angle adjustment is performed.

The aiming execution module 400 performs aging of the headlamp 30 based on the horizontal / vertical adjustment angle of the headlamp 30 provided from the ECU 340. [

That is, the camming of the head lamp 30 is automatically performed through the aiming execution module 400 so that the optimum irradiation angle is achieved, so that the driver can conveniently obtain optimum visibility.

10 is a flowchart showing an operation method of an aiming device of a vehicle lamp according to an embodiment of the present invention.

As shown, the image acquisition module 100 illuminates the light of the headlamp 30 when the vehicle 10 is positioned at the first distance 40 from the wall surface 2, And irradiates the light of the head lamp 30 when the vehicle 10 moves a predetermined distance toward the wall surface 2 and is located at the second distance 40 'from the wall surface, And acquires a second image of the beam pattern formed on the substrate 2 (S910).

Off detection unit 210 detects the cutoff line 5 in the beam pattern of the first image 50 and the second image 50 ', the aiming point setting module 200 detects the cutoff line 5 from the first image 50 (5) at a point corresponding to the first aiming point (6) in the second image (50 ') and a second image point 2 aming point 6 'is obtained (S920).

When the ECU 340 displays the first aiming point 6 and the second aiming point 6 'in a top view viewed from above the vehicle 10, the first aiming point 6 and the second aiming point 6' 2 of the headlamp 30 of the vehicle 10 using the aiming point 6 '. In addition, the distance between the vehicle 10 and the wall surface 2 is calculated based on the vertical distance on the top view between the first aiming point 6 and the second aiming point 6 '(S930). Since the process of calculating the horizontal adjustment angle of the head lamp 30 of the vehicle 10 and the distance between the vehicle 10 and the wall surface 2 has been described with reference to Figs. 8 (a) to 8 (c) The description is omitted.

The ECU 340 adjusts the steering angle so that the vehicle 10 is linearly moved based on the steering angle sensed by the steering angle sensing unit 320 (S940). Here, when the sensed steering angle is an angle at which the vehicle 10 is moved in a straight line, the steering angle is not adjusted separately. In this case, step S940 may be omitted.

In the present invention, the step of adjusting the steering angle (S940) is performed after step S930, but this is merely an example for facilitating understanding of the present invention, and the present invention is not limited to this, and any of steps S910 to S950 Step < / RTI >
