Abstract: The method of imaging a lumber board generally has the steps of: emitting laser light along a laser plane and toward a transit plane from both opposite sides thereof, in a manner to form a pair of opposite transversal lines of laser light on the lumber board as the board is conveyed across the laser plane; recording a plurality of images of the transversal lines of laser light as the board is conveyed across the laser plane, with each image being associated to a corresponding longitudinal position of the board along the transit plane; and producing a mapping of the geometry of the board by correlating, for each one of the images, the position of points located along the transversal lines of laser light in the recorded images with tridimensional coordinates in a conveyor reference system using tracking data indicative of the movement of the lumber board and calibration data.

Abstract: The invention relates to a method for video processing of at least one image of a video sequence, said video sequence comprising a plurality of image pairs, each image pair comprising a first image and a second image said first and second images being intended to form a stereoscopic image. In order to reduce display defects, the method comprises a step of generation of at least a third image by motion compensated temporal interpolation from at least two of said second images.
