摘要： A method for scanning an object in three dimensions that includes providing a handheld device and a first lens assembly, the first lens assembly removably attached to the body, the first lens assembly including a first lens and a support, the support configured to provide a fixed position for the first lens relative to the display; projecting a pattern of structured light onto the object from a display screen of the handheld device; acquiring at least one image of the structured light pattern projected onto the object using a camera integrated into the handheld device; converting each of the at least one image into digital values; and determining three-dimensional coordinates of the object based a triangulation calculation, the triangulation calculation based at least in part on the digital values and the projected pattern of the structured light.

摘要： A method for determining three-dimensional coordinates of an object point on a surface of an object, the method including steps of: providing a source, a projector, and a camera; in each of two instances: spatially modulating source light; sending a modulator pattern of light through the projector lens to form light spots; filtering the spots with a pinhole plate; propagating light from the light spots onto the object to produce a fringe pattern; imaging the object point with a camera lens onto an array point of the photosensitive array to obtain first and second electrical data values from the photosensitive array; and determining the three-dimensional coordinates of the first object point based at least in part on the first electrical data value, the second electrical data value, and a baseline length.

摘要： A method for determining three-dimensional coordinates of an object point on a surface of an object, the method including steps of: sending a beam of light to a diffraction grating; sending a first diffracted beam and a second diffracted beam to an objective lens to form at least two spots of light, which are passed through transparent regions of a plate to produce a first fringe pattern on the surface of the object; imaging the object point illuminated by the first fringe pattern onto a photosensitive array to obtain a first electrical data value; moving the plate to a second position; sending spots through plate to produce a second fringe pattern on the surface of the object; imaging the point onto the array point to obtain a second electrical data value; and calculating the three-dimensional coordinates of the first object point.

摘要： A method for determining three-dimensional coordinates of an object point on a surface of an object, including steps of providing a transparent plate having a first region and a second region, the second region having a different wedge angle than the first region; splitting a first beam of light into a first light and a second light; sending the first light through the first region or the second region; combining the first light and the second light to produce a fringe pattern on the surface of the object, the pitch of the fringe pattern depending on the wedge angle through which the first light travels; imaging the object point onto an array point on a photosensitive array to obtain an electrical data value; determining the three-dimensional coordinates of the first object point based at least in part on the electrical data value.
