Abstract: In this method, the conductive powder mass is placed on the support, and then the member is placed on the mass and a compression force is applied, urging the member against the mass and the support before heating the mass. The magnitude is increased from an initial value to a first predefined value for agglomerating the mass, which value is less than a plastic deformation threshold of the powder mass. Then, the magnitude is maintained at the first predefined value throughout a predetermined duration for agglomerating the powder mass. Finally, the magnitude is increased from the first value to a second predefined value less than a critical threshold for damaging the member but greater than a minimum threshold for sintering the mass at the predetermined temperature, the second predefined value being greater than the first predefined value.

Abstract: A method and apparatus to extract a dense three-dimensional model of an observed scene or object from one or more sequences of images acquired with an imaging device such as a camera or camcorder, or clusters of cameras and/or camcorders. In some embodiments the method includes capturing an image sequence by a camera moving with a translateral motion, for example moving on a straight path with a fixed orientation. The images in each sequence are captured at regularly spaced sites on the straight path. In some embodiments, a device projects structured light on the observed scene. Multiple image sequences can be acquired, on different cameras on straight paths. The captured image sequences are input to a computer. The 3D structure of the scene viewed by each image sequence is computed. Dense reconstruction from EPIs is performed by interpolating the EPIs after having detecting straight segments on the EPIs.
