DEPTH MEASUREMENT SYSTEM USING ROTATING MIRROR AND MONO-CAMERA

摘要

The present invention relates to a distance measuring device using a rotating plane mirror and a single camera. More specifically, by placing a plane mirror rotating in front camera disposed with the light incident parallel to the linear camera (striped light) when a plane mirror is a plane mirror can reflect the linear light while rotating the light beam is scanned in the target object. When, light located on the measurement object (the light points) are captured by the camera through the flat light again with the image of the target object, the position of the linear beam (striped light) in the camera image is light from the plane mirror is determined by the distance to the object is . The invention inde manner that results in the linear beam to scan the object plane wonder rotation, this time, the light source and the plane mirror, the virtual image plane mirror which is light on the object by the geometry of the camera always bear on the optical axis irrespective of the angle of the plane mirror himyeo the position is the same as the distance between the plane mirror and the object. In addition, since the position of the point light in camera image is determined by the position of the virtual image on the optical axis, and to calculate the distance of an object by the light captured by the image point position, the angle of rotation of the measuring object plane mirror easy is characterized in that the conversion by each. The present invention is less diffusion phenomenon of the pixel values for the linear light, a much more accurate than using the linear light source and the vision features a simple distance measurement is available.
