Technical Field

The present invention relates to a calibration device, and more particularly, to a horizontal calibration device and a horizontal calibration method.

Background

In performing ADAS (Advanced Driver Assistance System) calibration, it is necessary to ensure that the ADAS calibration device is on a parallel horizontal plane with the vehicle. In calibration, a vehicle center position needs to be obtained, and it is necessary to ensure that the vehicle to be calibrated and the ADAS calibration device are on a parallel horizontal plane.

In practice, the following may be the case during ADAS calibration: the ground is in an uneven state. Secondly, the ground is smooth, but the air pressure difference of the tires causes the vehicle body of the vehicle to be in a non-horizontal plane state. And thirdly, the ground and the vehicle are both in a horizontal state, but the vehicle-mounted ADAS device is in a non-horizontal state after being mounted on the vehicle. Therefore, in performing ADAS calibration, the vehicle needs to be calibrated horizontally.

The horizontal calibration method comprises the following steps:

and S410, respectively arranging the first auxiliary measuring component and the second auxiliary measuring component at two symmetrical positions on the left and right of the vehicle.

The first auxiliary measuring component and the second auxiliary measuring component are both provided with a light reflecting area and a light non-reflecting area. The mounting positions of the first auxiliary measuring component and the second auxiliary measuring component can refer to fig. 3, including but not limited to a wheel rim, a rear view mirror, a front windshield right lower corner and the like. The first auxiliary measuring component and the second auxiliary measuring component can be arranged close to the vehicle head, can also be arranged close to the vehicle tail, or are arranged close to the middle part of the vehicle body. When the device is installed, the first auxiliary measuring component and the second auxiliary measuring component can be adjusted horizontally and vertically.

And S420, arranging the first side end alignment part and the second side end alignment part on a horizontal support and leveling.

The laser ranging assembly has a positioning and transmitting function, and in one embodiment of the application, the laser ranging assembly can transmit a laser point/line or a laser combined pattern. The laser ranging assembly may also be a lidar.

The first side end alignment part and the second side end alignment part are firstly leveled before calibration, and for this purpose, the horizontal support part is firstly leveled to ensure that the bearing surface of the horizontal support part is horizontal. Specifically, horizontal bubbles and other parts can be arranged at two ends of the horizontal support member, and leveling can be performed by using the horizontal bubbles and other parts. The horizontal support may be a bracket, a base, or the like.

And S430, aligning the first side end alignment part with the first auxiliary measuring part, and adjusting the distance between the first side end alignment part and the second side end alignment part to D1.

Since the first side end alignment member and the second side end alignment member are provided on the horizontal support, the position of the horizontal support is first adjusted according to the height of the first auxiliary measuring member. After the first side alignment member is aligned with the first auxiliary measuring member, an attempt is made to align the second side alignment member with the second auxiliary measuring member by adjusting the position of the second side alignment member on the horizontal support. D1 is the spacing between the first auxiliary measuring member and the second auxiliary measuring member, so that the spacing between the second side alignment member and the first side alignment member is also adjusted to D1 after the first side alignment member is aligned with the first auxiliary measuring member. If the second side end alignment component is not aligned with the first auxiliary measurement component, the left side and the right side of the vehicle are judged not to be on the same horizontal plane; if so, the process proceeds to step S440.

And S440, measuring the distance L1 between the first side end alignment part and the first auxiliary measuring part.

Since the first side end alignment member has been aligned with the first auxiliary measuring member, L1 may be measured by the laser ranging assembly of the first side end alignment member.

And S450, measuring the distance L2 between the second side end alignment part and the second auxiliary measuring part.

It is understood that steps S440 and S450 may be performed simultaneously, or step S440 may be performed first and then step S450 may be performed, and vice versa. If L1 ≠ L2, it is determined that the left and right sides of the vehicle are not on the same horizontal plane.

And if the first side end alignment part is not aligned with the third auxiliary measurement part, judging that the vehicle head and the vehicle tail are not on the same horizontal plane.

Referring to fig. 5, if the first side end alignment part is aligned with the first auxiliary measurement part and the second side end alignment part is aligned with the second auxiliary measurement part, it can be determined whether the vehicle head and the vehicle tail are at the same level according to whether the second side end alignment part is aligned with the fourth auxiliary measurement part, that is, if the second side end alignment part is not aligned with the fourth auxiliary measurement part, it is determined that the vehicle head and the vehicle tail are not at the same level.
