Embodiment 1

[0027] This embodiment relates to a device for measuring the wheelbase of a vehicle based on an infrared range finder, such as figure 1 As shown, the device is installed on the ground in the middle of the parking space; the device includes a track 4 parallel to the long side of the parking space, on which an infrared range finder 1 and a displacement sensor 2 that can slide simultaneously are arranged, The infrared range finder 1 is mounted on a slide block 3 that can slide along the track; the testing direction of the infrared range finder 1 is perpendicular to the track 4 .

[0028] Use the method for measuring the vehicle wheelbase based on the infrared rangefinder-based measuring vehicle wheelbase device in this embodiment, such as figure 2 As shown, the method includes:

[0029] S1: Raise or open the infrared rangefinder and the displacement sensor, so that the infrared rangefinder protrudes from the ground, slide the slider to one end of the track, and record it as the...

Abstract

The invention relates to the technical field of vehicle appearance measurement, in particular to a device and a method for measuring a vehicle axle distance based on an infrared range finder. The device is installed on the ground in the middle of a parking space. The device comprises a rail parallel to the long side of the parking space, an infrared distance meter and a displacement sensor which can slide at the same time are arranged on the rail, and the infrared distance meter and the displacement sensor are installed on a sliding block capable of sliding along the rail in a liftable or foldable mode. The testing direction of the infrared range finder is perpendicular to the rail. The device is simple in structure and convenient to manufacture, does not need to be installed on stand columns or ceilings or roller shutter doors or other external structures, and cannot hinder the periphery of the parking space; a hidden structure is arranged, so that the whole device can be hidden underthe ground, and vehicles, users and parking robots cannot be hindered; and the axle distance is calculated through the Pythagorean theorem, so that the parking space is not required to be parallel tothe parking space, precision is high, and errors are small.

Description

technical field [0001] The invention relates to the technical field of vehicle appearance measurement, in particular to a device and method for measuring vehicle wheelbase based on an infrared range finder. Background technique [0002] The parking hall is the vehicle pick-and-place room of a large unmanned intelligent parking lot. It is used for automatic pick-and-place of vehicles by drivers, automatic pick-and-place of vehicles by parking robots, and automatic measurement of vehicle appearance information. It is the link between drivers and intelligent parking lots. The vehicle handover room and the automatic measurement room for vehicle appearance information. [0003] Existing parking halls generally have peripheral structures such as columns, ceilings, and rolling doors. Measuring devices such as laser radar ranging devices and camera ranging devices are installed on these peripheral structures to measure the appearance of vehicles. However, for users who use smart pa...
