Abstract
An apparatus for target location is disclosed. The apparatus includes a housing, which includes a range sensor to generate range data, an image sensor to generate image data, an inertial sensor to generate inertia data, and a processor. The processor is configured to receive the image data from the image sensor and determine a first orientation of the housing and receive the inertia data from the inertial sensor and modify the first orientation based on the inertia data to produce a modified orientation of the housing.
Claims20
An apparatus for target location, comprising:
- a portable housing comprising:
- a range sensor to generate range data;
- an image sensor to generate image data;
- an input port for receiving GPS location data of the housing location;
- an inertial sensor to generate inertia data;
- and
- a processor to:
- receive the image data from the image sensor and the housing location data from the input port via a user input device coupled to the input port, and determine a first orientation of the housing based on the image data and the housing location data;
- and
- after moving the portable housing, receive the inertia data from the inertial sensor and modify the first orientation of the housing based on the inertia data to produce a modified orientation solely of the housing and not of the target.
A method for target location using a portable housing, comprising:
- receiving image data from an image sensor in the housing and housing location data via a user input device, and determining a first orientation of the housing based on the image data and the housing location data;
- and
- receiving inertia data from an inertial sensor in the housing and modifying the first orientation of the housing based on the inertia data to produce a modified orientation solely of the housing and not of the target.
A non-transitory computer-readable medium comprising instructions that, when executed by a processor, cause the processor to:
- receive image data from an image sensor and housing location data via a user input device, and determine a first orientation of a portable housing for the processor based on the image data and the housing location data;
- and
- receive inertia data from an inertial sensor and modify the first orientation of the housing based on the inertia data to produce a modified orientation solely of the housing and not of the target.
