Dense 3D surface acquisition by structured light using off-the-shelf components
TL;DR: This paper describes the implementation of a LCD stripe projection system, based on a new processing scheme called line shift processing, that allows an off-the-shelf multimedia projector to acquire dense 3D data of large objects in a matter of seconds.
Dense 3-D surface acquisition by structured light using off-the-shelf components
TL;DR: In this paper, the authors describe the implementation of a LCD stripe projection system, based on a new processing scheme called line shift processing, which allows the projection device can, but is not requiredto be stable over time nor does it have to be calibrated.

Laser range finder based on synchronized scanners
TL;DR: A new geometrical arrangement is proposed to improve performances of optical triangulation, which allows considerable reduction of the optical head size compared with usual geometries, so the shadow effects are reduced proportionally.

Two New Edge Detectors
TL;DR: This paper introduces two new edge detection algorithms that uses multiple difference-based edge detectors, one of which selects peak center by absolute maximum or center of mass techniques and the other uses multiple three-state edge masks to find edge positions.

Method and device for determining the existence and the time position of main peaks appearing in an electronic signal
TL;DR: In this article, a method of examining an electrical signal to determine the time position of any main peaks in the signal comprises: dividing the signal into consecutive time intervals; allocating a variable reference level, called the cut-off level, to each of said time intervals, the value of said cutoff level being selected by analysing amplitude measurements made on the signal in a number of time intervals including the time interval to which the cutoff value is allocated.
