    Abstract: A safety sensor system and method is provided. The method includes projecting from a projector a pattern of light to a first position. The pattern of light being generated by a shape control element with each of the first pattern of light having a pattern pose. A first image is captured with a camera of the first pattern of light. The pose or shape of the pattern of light is changed using the shape control element. A pattern pose or shape information is determined from both images. It is determined that the second image is valid based on the pattern pose or shape information differing by more than predetermined measurement errors or the pattern pose or shape information differing less than predetermined measurement errors from values that are based on the control values transmitted to the pattern pose and shape control element.

    Abstract: A triangulation scanner includes a projector, a camera, and a processor, the projector projecting a first pattern of light on a first point during first intervals and a no light during second intervals, the camera including an optical detector, a first accumulator, and a second accumulator, the optical detector receiving reflected light from the first point, the first and second accumulators summing signals from the optical detector during the first and second intervals, respectively, the processor determining 3D coordinates of the first point based at least in part on the first pattern, the summed signals from the first and second accumulators, and a speed of light in air.

    Abstract: A three-dimensional (3D) coordinate measuring system is provided. The system includes an aerial measuring device that has an aerial drone and a 3D measurement device. The 3D measurement device being rotatably attached to the aerial drone, the aerial drone is movable from a first position to a stationary second position. The 3D measurement device being configured to optically measure points on the surface of an object. The system further includes one or more processors configured to execute nontransitory computer readable instructions. The computer readable instructions comprise: moving the aerial measuring device from the first position; landing the aerial measuring device at the second position; rotating the 3D measurement device to optically measure a first object point; and determining a first 3D coordinates of the first object point with the 3D measuring device.
