Embodiment 1

[0027] This embodiment relates to a device for measuring the wheelbase of a vehicle based on a camera device. The device includes a vertically arranged binocular camera 1 with a distance measuring function, and the binocular camera 1 is installed on a rotating shaft 4 perpendicular to the ground. Above; the rotating shaft 4 can be driven by the servo motor 5 to rotate with the axis as the center; the device is installed in the installation groove on the ground near the parking space. The device also includes a hidden camera structure, which is a lifting structure, which can lower the rotating shaft and the binocular camera below the ground.

[0028] In this embodiment, the device for measuring the wheelbase of the vehicle based on the camera device is set at a position about 60 cm from the middle of the right side of the parking space to the left edge of the parking space.

[0029] Use the method for measuring the wheelbase of a vehicle based on the device for measuring the wh...

Abstract

The invention belongs to the technical field of vehicle appearance measurement, and particularly relates to a device and a method for measuring a vehicle axle distance based on a binocular camera device. The device comprises a binocular camera which is vertically arranged and has a distance measuring function, and the binocular camera is installed on a rotating shaft perpendicular to the ground; and the rotating shaft can be driven by a servo motor to rotate with the axis as the circle center and is installed in an installation groove in the ground close to one side of the parking space. According to the method, the wheelbase of the vehicle is calculated through the cosine law; 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 under theground, and vehicles, users and parking robots cannot be hindered; and the axle distance is calculated through the cosine law, so that precision is high, and errors are small.

Description

technical field [0001] The invention belongs to the technical field of vehicle appearance measurement, and in particular relates to a device and method for measuring vehicle wheelbase based on a binocular camera device. 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...
