Abstract:
1. A sensor for vehicle height measurement capable of measuring vehicular slant, comprising: a base board; a light source having a length direction extending parallel with a longitudinal axis of the light source, the light source being located adjacent to the base board and configured to emit a linear light about an optical axis and in a light emitting direction opposite the base board; a first camera having a length direction extending parallel with a longitudinal axis of the first camera, the first camera being located adjacent to the base board, and the length direction of the first camera being substantially perpendicular to the length direction of the light source; a second camera having a length direction extending parallel with a longitudinal axis of the second camera, the second camera being located adjacent to the base board and opposed to the first camera, and the length direction of the second camera being located substantially on a virtual extension line extending linearly from the length direction of the first camera across the light source; and a pair of lenses having a focus and a focal length each of the lenses located in front of a respective one of the first camera and the second camera, wherein a virtual line connecting the focuses of the pair of lenses, a virtual line connecting the focal lengths of the pair of lenses, and the virtual extension line connecting the first camera to the second camera are located substantially in parallel and on a same virtual surface, and the first camera and the second camera are configured to photograph a road image of the substantially same virtual extension surface that is generated by the linear light emitted from the light source.
