    Abstract: A three-dimensional (3D) measurement system, method and computer program product are provided. The system includes a noncontact measurement device that measures a distance from the noncontact measurement device to a surface. The device includes a projector that emits a light pattern. A measurement camera is coupled to the noncontact measurement device. A first color camera is provided having a first quality parameter. A second color camera is coupled to the device, the second color camera having a second quality parameter, the second quality parameter being larger than the first quality parameter. One or more processors are operably coupled to the noncontact measurement device that determine 3D coordinates of at least one point in a field of view and selectively acquiring an image with the second color camera.

    Abstract: A system and method of determining three-dimensional coordinates is provided. The method includes, with a projector, projecting onto an object a projection pattern that includes collection of object spots. With a first camera, a first image is captured that includes first-image spots. With a second camera, a second image is captured that includes second-image spots. Each first-image spot is divided into first-image spot rows. Each second-image spot is divided into second-image spot rows. Central values are determined for each first-image and second-image spot row. A correspondence is determined among first-image and second-image spot rows, the corresponding first-image and second-image spot rows being a spot-row image pair. Tach spot-row image pair having a corresponding object spot row on the object. Three-dimensional (3D) coordinates of each object spot row are determined on the central values of the corresponding spot-row image pairs. The 3D coordinates of the object spot rows are stored.

    Abstract: Provided are embodiments for a device and method for measuring three-dimensional (3D) coordinates. Embodiments include a projector having a projector optical axis on a first plane, the projector operable to project a collection of laser beams on a surface of an object, and a first camera having a first-camera optical axis on the first plane, the first camera operable to capture a first image of the collection of laser beams on the surface of the object. Embodiments also include one or more processors, the one or more processors are operable to generate a first distance profile for the object using a first laser beam of the collection of laser beams and generate a second distance profile for the object using a second laser beam of the collection of laser beams, estimate the velocity of the object based on the first and second distance profile, and provide the estimated velocity.

    Abstract: A method and system for inspecting an object is provided. The system includes a measurement device that measures 3D coordinates of points on a surface of the object. A display is coupled to the device and is sized to be carried by an operator. One or more processors cooperate with the measurement device, to perform a method comprising: determining 3D coordinates of the points while the object is being measured; aligning an electronic model of the object to the points while the object is being measured; determining a variance between the electronic model and the points while the object is being measured; and displaying on the display an indicator when the variance exceeds a threshold while the object is being measured.
