Hardware and System for Single-Camera Stereo Range Determination
First Claim
1. A range determiner assembly comprising:
- an image sensor configured to obtain image data for each of three views of a target at each of a plurality of different locations along the track of a craft moving at a determinable altitude above a surface of the earth;
a detector board comprising a first line array, a second line array and a third line array, each of the first, second and third line arrays receiving a respective sequence of images from a corresponding one of the three views; and
processing circuitry configured to determine a relative distance between the craft and the target based on the image data.

Abstract
A range determiner assembly may include an image sensor, a detector board and processing circuitry. The image sensor may be configured to obtain image data for each of three views of a target at each of a plurality of different locations along the track of a craft moving at a determinable altitude above a surface of the earth. The detector board may include a first line array, a second line array and a third line array. Each of the first, second and third line arrays may receive a respective sequence of images from a corresponding one of the three views. The processing circuitry may be configured to determine a relative distance between the craft and the target based on the image data.

13. A method of determining range to a target, the method comprising:
-
obtaining image data at three different angles to provide three near-coincident views of a target at each of a plurality of different locations along a track of a craft moving at a determinable altitude above a surface of the earth; providing the image data to a detector board comprising a first line array, a second line array and a third line array, each of the first, second and third line arrays receiving a respective sequence of images from a corresponding one of the three views; and determining a relative distance between the craft and the target based on the image data. - View Dependent Claims (14, 15, 16, 17, 18, 20)
