Patent Images
1. A method of image-tracking comprising:
- (A) performing an image-capture of a scene by using an image capturing device;
(B) generating a set of captured image data and a set of scene depth data; and
(B1) performing a rigid global transformation of said set of captured image data and said set of scene depth data into a set of 6-coordinate data;
wherein said set of 6-coordinate data represents movement of said image capturing device.

18. A method of image-tracking comprising:
-
(A) performing an image-capture of a scene by using an image capturing device; (B1) determining said set of scene depth data in an image capturing device—
attached 3D reference system by using a K-point range measurement system attached to said image capturing device, wherein said set of scene depth data comprises an integer K-point set of 3D depth measurements of said scene; and
wherein a 3D depth coordinate of at least one object point associated with a 2D image point of said 3D object point is obtained by interpolation of said K-point set of 3D depth measurements of said scene to obtain an optimum depth measurement for at least one image point of at least one said object point; and
wherein said integer K is substantially less than number of pixels in said frame;and (C) tracking movement of said image capturing device by analyzing said set of images.

19. A method of image-tracking comprising:
-
(A) performing an image-capture of a scene by using an image capturing device; (B2) determining said depth of said object point directly for at least one image point of said object point by using an M-point range measurement system attached to said image capturing device, wherein said integer number M of depth measurements of said scene is substantially equal to the number of pixels in said frame; and (C) tracking movement of said image capturing device by analyzing said set of images.

20. A method of image-tracking comprising:
-
(A) performing an image-capture of a scene by using an image capturing device; (B3) determining said set of scene depth data in an image capturing device—
attached 3D reference system by using a feature-point range measurement system attached to said image capturing device, wherein said scene comprises a set of integer K feature object points;wherein said feature-point range measurement system obtains a K set of 3D depth measurements of said K feature object points in said scene; and wherein a 3D depth coordinate of at least one object point associated with a 2D image point of said 3D object point is obtained by interpolation of said K-point set of 3D depth measurements of said scene to obtain an optimum depth measurement for at least one image point of at least one said object point; and wherein said integer K is substantially less than the number of pixels in said frame; and (C) tracking movement of said image capturing device by analyzing said set of images.

(A) performing an image-capture of a scene by using an image capturing device; (B) obtaining a set of scene depth data by using a range measurement device selected from the group consisting of;
{a point laser beam;
a sonar;
a radar;
a laser scanner; and
a depth camera};and (C1) performing a rigid global transformation of said set of captured images data and said set of scene depth data into a set of 6-coordinate data;
wherein said set of 6-coordinate data represents movement of said image capturing device. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36)
