摘要： Method and device(s) for provision of a pair of real world and image sensor correspondence points for use in calibration of an imaging system (405) for three dimensional imaging based on light triangulation. Said real world point (514-1; 529-1) being provided (801) as a first virtual intersection between a first real world line (512a; 527a) and a second real world line (512b; 527b). Said image sensor point (544-1; 554-1) being provided (802) as a second virtual intersection between a first image line (542a; 552a) and a second image line (542b; 552b). A first image (540a; 550a) by the imaging system comprises captured light that images the first real world line (512a; 527a) and a second image (540b; 550b) by the imaging system comprises captured light that images the second real world line (512b; 527b). The first image line (542a; 552a) corresponds to positions of intensity peaks of said captured light in the first image (540a; 550a) and the second image line (542b; 552b) corresponds to positions of intensity peaks of said captured light in the second image (540b; 550b).

摘要： A method for dynamic 3D scanning of a spatial object comprising the following steps: projecting (101) a sinusoidal fringe pattern (4a) onto a spatial object (5) by a projector (2) of a dynamic 3D scanner (1), capturing (102) by at least one camera (3) of the dynamic 3D scanner (1) at least one sinusoidal frame of the spatial object (5) with the sinusoidal fringe pattern (4a) on surface, projecting (103) a coding fringe pattern (4b) onto the spatial object (5) by the projector (2) of the dynamic 3D scanner (1), capturing (104) by at least one camera (3) of the dynamic 3D scanner (1) at least one coding frame of the spatial object (5) with the coding fringe pattern (4b) on its surface, generating (106) a sequence of de-noised sinusoidal frames with phase shift, based on at least one captured (102) sinusoidal frame; generating (108) a wrapped phase map from the sequence of the de-noised sinusoidal frames with phase shift, correlating (115) the wrapped phase map with the coding frame to obtain (116) a pixel map with data comprising assigned period numbers, and a map of probability values of assigning period numbers, filtering out (117) from the pixel map with data comprising assigned period number areas having on the map of probability values of assigning the period numbers a value ≤ 0.99, reconstructing (118) the filtered out areas from the pixel map, generating (119) an unwrapped phase map from the wrapped phase map and the pixel map with reconstructed (118) filtered out areas, reconstructing (120) a 3D image of the spatial object based on the unwrapped phase map, wherein the coding fringe pattern (4b) comprises strips and the coding fringe pattern (4b) is arranged such that the pixel width/height of the strips is equal to an oscillation period of a sinusoidal waveform of the sinusoidal frame, every second strip comprises a fringe unit pattern, each of the fringe unit patterns constitutes an area comprising at most the number of pixels corresponding to the number of pixels determining the pixel width/height of the strips, each of the fringe unit patterns occurs maximum of two times in the coding fringe pattern, each of the fringe unit pattern comprises at least one of three component RGB channels, wherein the brightness level of each of the component RGB channel is the same and is selected from 0%, 50%, 100%; and wherein the sequence of de-noised sinusoidal frames with phase shift comprises a set of four de-noised frames comprising a sine signal, cosine signal, π-shifted sine signal, π-shifted cosine signal.

摘要： A three-dimensional measuring apparatus includes a projection unit that projects a pattern onto a subject, a plurality of image capturing units that capture images of the subject from mutually different points of view, and a processing unit that calculates a distance value to the subject by performing association using image groups captured of the subject by the plurality of image capturing units, wherein the processing unit integrates information based on a first image group that was captured by projecting the pattern onto the subject, and information based on a second image group that was captured without projecting the pattern onto the subject, into integrated images or evaluation values to be used during the association such that features of the images from both the first image group and the second image group remain, and calculates the distance value using the integrated images that have been integrated or the evaluation values.
