摘要： A method for measuring a distance includes modulating the light beam at a first frequency, receiving a second beam by the optical detector to produce a first electrical signal having the first frequency and a first phase; modulating the light beam at a second frequency different than the first frequency; receiving the second beam by the optical detector to produce a second electrical signal having the second frequency and a second. After these steps, the retroreflector is moved while modulating the light beam continuously at the second frequency; and a first distance to the retroreflector is determined based at least in part on a the first and second frequencies and phases.

摘要： A method is provided for determining the three dimensional coordinates of points on the surface of an object. The method includes providing a structured light scanner and a coordinate measurement device. The coordinate measurement device tracks the location and orientation of the structured light scanner during operation. The location and orientation data is combined with image frames captured by the scanner to allow registration of the image frames relative to each other. The three-dimensional coordinates of points on the surface of the object may then be determined in the frame of reference of the coordinate measurement device.

摘要： An assembly that includes a projector and camera is used with a processor to determine three-dimensional (3D) coordinates of an object surface. The processor fits collected 3D coordinates to a mathematical representation provided for a shape of a surface feature. The processor fits the measured 3D coordinates to the shape and, if the goodness of fit is not acceptable, selects and performs at least one of: changing a pose of the assembly, changing an illumination level of the light source, changing a pattern of the transmitted With the changes in place, another scan is made to obtain 3D coordinates.

摘要： A method of measuring spherically mounted retroreflector (SMR) with a 3D coordinate measurement device such as a laser tracker. The SMR includes an open-air cube corner retroreflector having a vertex point located near a sphere center of the SMR. Measurements of the SMR to the vertex point are corrected to indicate 3D coordinates of the SMR sphere center by accounting for SMR depth error and SMR runout error.

摘要： A method for optically communicating, from a user to a laser tracker, a command to direct a light beam from the tracker to a retroreflector and lock onto the retroreflector includes projecting a first light to the retroreflector. Also, moving by the user the retroreflector in a predefined spatial pattern which corresponds to the command; reflecting a second light from the retroreflector, the second light being a portion of the first light; obtaining first sensed data by sensing a third light which is a portion of the second light and imaging the third light onto a photosensitive array on the tracker and converting the third light on the photosensitive array into digital form. Further, determining the first sensed data corresponds to the predefined spatial pattern; pointing the light beam from the tracker to the retroreflector; and locking onto the retroreflector with the tracker light beam.
