Patent ID: 11922653
Assignee: FORSBERG SERVICES LTD.
Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 0:
1. An object locating system comprising:
a. a computing device comprising a transceiver;
b. at least three datums, each datum comprising:
i. a positioning device calibrated relative to the positioning devices of the other datums; and
ii. a transceiver adapted to broadcast—to the transceiver of the computing device—a position of the datum;

c. an observation device comprising:
i. a camera adapted, in use, to capture an image of a scene containing an object whose position is to be determined and at least two of the datums; and
ii. a range finder adapted, in use, to measure the distance or distances between the observation device and at least one object within the field of view of the camera; and
iii. a transceiver adapted to broadcast—to the transceiver of the computing device—the captured image and the or each measured distance or distances; wherein, the computing device being is adapted:
d. to calculate an azimuth and elevation angle between two datums, or between the optical axis of the camera and each datum, in the image;
e. to triangulate the position and attitude of the camera at the time the image was captured using received position data for each datum at the time the image was captured; and
f. to calculate an azimuth and elevation angle between an optical axis of the camera and the object in the image; and knowing the position and attitude of the camera and a distance to the object at the time the image was captured, to triangulate a position of the object at the time the image was captured.
