Embodiment Construction
[0043] A vehicle profile measurement method based on vector image measurement in the present invention, such as figure 1 As shown, the side wall 4 of the tunnel in the detection area is provided with a limited detection cabinet 3 and a vehicle boundary line 2 . Define the space vector measurement coordinate system: the x-axis points to the positive direction of the paper, indicating the direction of travel of the train; the x-axis rotates 90° counterclockwise, which is the positive direction of the y-axis; the y-axis rotates 90° clockwise, which is the positive direction of the z-axis .
[0044] Several definitions:
[0045] Object outline: CJJ / T 96-2018 "Metro Gauge Standard" stipulates the three-dimensional coordinate values of the outline points in the spatial coordinate system (referenced by the rail plane and center line); and eliminates the influence of dynamic settlement and lateral offset of the track.
[0046] Line array plane: the angle between the length directi...
