1. A system comprising:
- a measurement device configured to send a first beam of light to a retroreflector target and to measure a distance, a first angle, and a second angle to the retroreflector target; and
a probe assembly including the retroreflector target, an inclinometer sensor, and a camera, the inclinometer sensor configured to determine a two-dimensional inclination of the probe assembly relative to a gravity vector, the retroreflector configured to reflect the first beam of light as a first reflected light, the camera configured to capture an image of a second light, the system being configured to determine six degrees of freedom of the probe assembly based at least in part on the measured distance, the measured first angle, the measured second angle, the measured two-dimensional inclination, and the captured image of the camera,wherein the second light is either a light emission from a light source on the measurement device or a reflection of the first reflected light off an window of the measurement device.

Abstract
A system includes a measurement device configured to measure a distance, a first angle, and a second angle to a retroreflector target. The system further includes a probe having the retroreflector target, an inclinometer sensor, a camera, and a processor, the inclinometer sensor configured to determine a two-dimensional inclination of the probe relative to a gravity vector, the camera configured to capture an image of a light emitted from or reflected by the measurement device, the processor configured to determine six degrees of freedom of the probe based at least in part on the distance, the first angle, the second angle, the two-dimensional inclination, and the captured image of the camera.
