Video signal recovery in measuring systems with optical triangulation sensors

The article considers the problem of video signal recovery by optical triangulation sensors. A video signal is a contour (sequence of points) on a plane. Due to the surface properties of the measured object, individual points of the object contour are not always recorded. Video signal recovery is based on the assumption that the object’s shape measured in short time intervals does not change signifi cantly. In this case, unregistered contour points can be restored from neighboring measurements. The recovery problem is solved by joining several superimposed contours. The contours are aligned along the segments of their lines and circles defi ned on the contour. The recovery algorithm was tested as part of the measuring system.
