DEVICE AND METHOD OF THREE-DIMENSIONAL OPTIC MEASUREMENT OF STRONGLY REFLECTING OR TRANSPARENT OBJECTS Russian patent published in 2013 - IPC G01B11/25 

FIELD: measurement equipment.

SUBSTANCE: three-dimensional object measurement device includes the first projection device containing the first infrared radiation source for projection to the object of the first moving pattern; at that, the projected pattern manifests itself as on the object in the form of heating distribution; at least one camera device for taking pictures of heating distribution, which manifests itself on the object, in infrared range of spectrum; as well as an analysing device for analysis of pictures taken with the camera device, and determination of the shape of the object surface. Three-dimensional object measurement method involves projection of the first infrared pattern on the object by means of the first projection device; taking pictures of heating distribution of the object by means of at least one camera device, which is sensitive to infrared radiation; at that, pattern between shots are offset; analysis of pictures by means of a topographometric analysis method and determination of the object surface shape.

EFFECT: providing the possibility of increasing contrast of the projected pattern on objects transparent for visible light or strongly reflecting the light.
