Embodiment Construction
[0043] 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. .
[0044] Such as figure 1 Shown is a schematic diagram of the curved test room. There are two curves in the curve test room, both of which include two curves with different curvatures. The curved test room is divided into 100 entry lines, 200 road sidelines, 300 road lines, and 400 exit lines. During the standard test, the vehicle enters the curve driving event through the entry line 100, and leaves the curve driving event through the exit line. During the entire driving process, the road sideline 200 is a non-touchable area, and it is not allowed to touch the road sideline 200. Points will be deducted directly if you touch it while driving.

The invention discloses an automatic scoring method of a curve traveling subject. The automatic scoring method comprises the steps that by means of a base station antenna arranged in a curve examination room, a plurality of pieces of position information in the curve examination room are determined, and a polygonal area is formed; by means of an antenna in an examination vehicle, a plurality of pieces of position information of the examination vehicle are determined when the examination vehicle entering the curve examination room passes through a curve bend formed by two curves; according to the position information of the curves and the position information of the examination vehicle, conversion of image coordinates and the position information is achieved, and the position relation between the examination vehicle and the curves is judged. According to the method, the position information of the examination vehicle in the curve examination room can be accurately acquired in real time,scoring can be carried out, the construction period of the examination room is shortened, the operation is convenient, and the cost is low.
Description
technical field [0001] The invention relates to the field of motor vehicle driving tests, in particular to an automatic scoring method for curve driving subjects. Background technique [0002] Passing the curve driving test is a subject in the field test for motor vehicle drivers. If the test vehicle presses or touches the edge line of the roadside during the test, the corresponding score will be judged according to the test. [0003] At present, a large number of sensors that require ground-breaking construction are commonly used in the test, and there are piezoelectric rubber strips that are pre-buried at the edge of the test site. When the wheel is pressed to the sideline, it can be sensed by the piezoelectric strip to determine the pressure line. Or there are pre-buried magnet groups or vehicle-mounted magnetic induction devices at the entrance of the test. The magnetic induction device senses the magnetic field formed by the corresponding magnet groups and transmits t...
