Abstract: A weighing device (1) has a load-bearing portion (10) that supports an object being weighed, a plurality of transition portions (20), and a separation portion (30). The transition portions are positioned on the separation portion, and the load-bearing portion is positioned on the transition portions, with the transition portions connected to the load-bearing portion and the separation portion. A plurality of weighing sensors (40) are provided at a bottom of the separation portion. A support portion (50) is below the weighing sensors to provide support therefor. The weighing device simplifies the loading condition of weighing sensors and isolates the horizontal mechanical deformation/distortion of the weighing load-bearing mechanism. It also reduces the influence of mechanical deformation/distortion, thereby improving the weighing performance and the effectiveness of the weighing device.

Abstract: A method for three-dimensional shape measurement provides for generating sinusoidal fringe patterns by defocusing binary patterns. A method for three-dimensional shape measurement may include (a) projecting a plurality of binary patterns onto at least one object; (b) projecting three phase-shifted fringe patterns onto the at least one object; (c) capturing images of the at least one object with the binary patterns and the phase-shifted fringe patterns; (d) obtaining codewords from the binary patterns; (e) calculating a wrapped phase map from the phase-shifted fringe patterns; (f) applying the codewords to the wrapped phase map to produce an unwrapped phase map; and (g) computing coordinates using the unwrapped phase map for use in the three-dimensional shape measurement of the at least one object. A system for performing the method is also provided. The high-speed real-time 3D shape measurement may be used in numerous applications including medical science, biometrics, and entertainment.
