  • Determining tilt angle and tilt direction using image processing
    Patent number: 9109889
    Abstract: A survey instrument includes a surveying device configured to perform survey measurements and an imaging device coupled to the surveying device and having a known spatial relationship with the surveying device. The imaging device may be configured to obtain image information. The survey instrument also includes a processor in electrical communication with the imaging device. The processor may be configured to receive the image information from the imaging device, process the image information to determine a pose of the imaging device, and determine a tilt angle of the survey instrument and a tilt direction of the survey instrument in a reference frame. Tilt angle and the tilt direction of the survey instrument may be determined using the pose of the imaging device.
