    Abstract: A system and method of inspecting a plurality of objects using a computed tomography (CT) system is provided. The method includes acquiring an image of a fixture used for holding the plurality of objects with the CT system. A first electronic model of the fixture is generated. The objects are placed in the fixture. An image of the fixture and the objects is acquired with the CT system. A second electronic model of the fixture and the objects is generated. A third electronic model of the objects is defined based at least in part on subtracting the first electronic model from the second electronic model. Dimensions of the objects from the third electronic model are compared with a computer aided design (CAD) model. A report is output based at least in part on the comparison of the objects from the third electronic model with the CAD model.

    Abstract: An imaging device and method of imaging a region. The imaging device includes a first camera and a first light source set at a periphery of the first camera, a second camera separated from the first camera by a selected distance and a second light source set at a periphery of the second camera, and a processor configured to operate the first light source set and the second light source set independently of each other. The region is illuminated using the first light source and a first image is obtained. The region is illuminated using the second light source and a second image is obtained. At least one of the first image and the second image includes an illumination effect.

    Abstract: A system and method for measuring three-dimensional (3D) coordinate values of an environment is provided. The system includes a movable base unit a first scanner and a second scanner. One or more processors performing a method that includes causing the first scanner to determine first plurality of coordinate values in a first frame of reference based on an emitted first beam of light and a received first reflected light. The second scanner determines a second plurality of 3D coordinate values in a second frame of reference as the base unit is moved from a first position to a second position. The determining of the first coordinate values and the second plurality of 3D coordinate values being performed simultaneously. The second plurality of 3D coordinate values are registered in a common frame of reference based on the first plurality of coordinate values.

    Abstract: A method for updating a digital representation of an environment includes capturing an image of a portion of the environment using a change-detection device. Further, a corresponding digital data is determined that represents the portion in the digital representation of the environment. A change in the portion is detected by comparing the image with the corresponding digital data. In response to the change being above a predetermined threshold, the method includes initiating a resource-intensive scan of the portion using a scanning device, and updating the digital representation of the environment by replacing the corresponding digital data representing the portion with the resource-intensive scan.

    Abstract: A virtual reality (VR) system that includes a three-dimensional (3D) point cloud having a plurality of points, a VR viewer having a current position, a graphics processing unit (GPU), and a central processing unit (CPU). The CPU determines a field-of-view (FOV) based at least in part on the current position of the VR viewer, selects, using occlusion culling, a subset of the points based at least in part on the FOV, and provides them to the GPU. The GPU receives the subset of the plurality of points from the CPU and renders an image for display on the VR viewer based at least in part on the received subset of the plurality of points. The selecting a subset of the plurality of points is at a first frame per second (FPS) rate and the rendering is at a second FPS rate that is faster than the first FPS rate.

    Abstract: A system includes a three-dimensional (3D) scanner that captures a 3D point cloud corresponding to one or more objects in a surrounding environment. The system further includes a camera that captures a control image by capturing a plurality of images of the surrounding environment, and an auxiliary camera configured to capture an ultrawide-angle image of the surrounding environment. One or more processors of the system colorize the 3D point cloud using the ultrawide-angle image by mapping the ultrawide-angle image to the 3D point cloud. The system performs a limited system calibration before colorizing each 3D point cloud, and a periodic full system calibration before/after a plurality of 3D point clouds are colorized.

    Abstract: Automatic selection of region in 3D point cloud is provided. Neighbor points are determined for given seed point of seed points. Responsive to a color difference of a given neighbor point from given seed point being less than neighbor color distance threshold and responsive to an angle between a normal of given neighbor point and a normal of given seed point being less than neighbor normal angle threshold, given neighbor point is added to region in 3D point cloud. Responsive to curvature at given neighbor point being less than curvature threshold, responsive to color difference of given neighbor point from initial seed point being less than initial seed color distance threshold and responsive to an angle between a normal of given neighbor point and a normal of initial seed point being less than an initial seed normal angle, given neighbor point is added to seed points for processing.
