Embodiment Construction

[0039] Below, the present invention will be further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of not conflicting, the various embodiments described below or the technical features can be combined arbitrarily to form new embodiments. .

[0040] Such as figure 1 As shown, the present invention provides a kind of vehicle body to the detection method of sideline distance, comprises the following steps:

[0041] S10: Determine the road sideline l through the reference station antenna installed on the road, determine the coordinates of the antenna through the antenna installed on the vehicle, and realize the transformation of the image and the plane coordinates;

[0042] S20: Calculate the coordinate values ​​(x 0 ,y 0 );

[0043] S30: Calculate the distance d from the vehicle body to the sideline according to the marker point and the road sideline l.

[0044] The position of the sidel...

Abstract

The invention discloses a method for detecting the distance between a vehicle body and a side line. The method includes the following steps that S10, the road side line 1 is determined through a basestation antenna arranged on a road, the coordinates of the antenna are determined through an antenna arranged in a vehicle, and conversion between an image and plane coordinates is realized; S20, thecoordinate values (x0, y0) of several mark points of the vehicle body are calculated according to the vehicle type of the vehicle, the installation position of the antenna and the antenna coordinatesobtained in S10; S30, according to the mark points and the road side line 1, the distance d between the vehicle body and the side line is calculated. The method does not need high-difficulty construction, is less affected by the outside and is easy to operate and high in precision.

Description

technical field [0001] The invention relates to the field of motor vehicle driving tests, in particular to a method and device for detecting the distance from a vehicle body to a sideline. Background technique [0002] In the test specification for subject three, the driver is required to pull over and stop so that the distance from the vehicle body to the ground edge reaches a certain distance requirement. If the distance is not up to the standard, relevant judgment points will be deducted. In the existing subject three electronic test evaluation system, in order to detect the distance from the vehicle body to the sideline, there are the following two methods. [0003] 1. It is realized by installing a special pressure sensor device on the ground. This method requires road reconstruction, which is costly and difficult to construct, and is prone to mechanical damage due to objective factors such as rainwater and ground pressure. [0004] 2. The distance from the vehicle to...
