A method for creating a 3D map of the surface contours of an object includes projecting a variety of patterns onto the object, and imaging the patterns as they fall on the object to encode the topographic features of the object. In one embodiment a three dimensional image is taken in a single flash to avoid blurring due to motion of the object. Thereafter a secondary pattern is projected to detect changes in the initial image. The images are processed in a computer program in a manner such that a complete 3D map of the surface of the object is obtained in digital form. Reiteration of the method can detect motional variation such as a breathing human, flexure of a complex mechanical structure, or a stress-strain testing of an airplane, vehicle, beam, bridge, or other structure.

The invention discloses a water-in-water multicolor paint preparation method capable of high-speed slicing and granulation. The preparation process comprises the following steps: preparing an 8% protective glue solution; 2. preparing a basic paint; 3. preparing a basic color paint; 4. preparing a multicolor particle solution; and 5. preparing the water-in-water multicolor paint finished product. After the color matching is carried out on the basic paint, the 8% protective glue solution is utilized to perform system reinforcement; and in the granulation and slicing process, the 8% protective glue solution and a hydrophobic modified anionic surfactant are premixed, so that the negative-valence ions in the anionic surfactant sufficiently capture cations on the nano modified magnesium lithium sodium silicate mineral salt molecule surface to form a series of strict film structures, thereby eliminating the risk of rejection caused by color bleeding, fusion and thickening since colored particles can not be completely coated in time. Thus, the obtained water-in-water multicolor paint has the advantages of excellent mechanical strength, excellent toughness and high spraying efficiency. The invention also discloses a composition of the water-in-water multicolor paint.
