Abstract
A method of assisting in focusing a three dimensional camera system on an object within a field of view is disclosed. The process involves at the camera system, determining a distance D in a z direction, within the field of view, to a current focal plane; and rendering to a display, an aimer graphic element with the Z direction distance equal to D in a manner that causes the aimer graphic element to move in the Z direction with changes in the focal plane.
Claims22
A system, comprising:
- a processing unit to determine a distance D in a z-direction corresponding to a three-dimensional coordinate system within a field of view of an imaging device to a current focal plane;
- and
- a display unit, coupled to the processing unit, to render an aimer graphic element with a z-direction distance equal to D in a manner that causes the aimer graphic element to move in the z-direction on the display unit with changes in the focal plane to assist in focusing the imaging device on an object in the field of view.
A system, comprising:
- a processing unit;
- display unit coupled to the processing unit;
- wherein the processing unit is configured to:
- determine a distance D in a z direction corresponding to a three-dimensional coordinate system, within a field of view of an imaging device to a current focal plane;
- calculate a depth of field distance ΔD;
- render, on the display unit, an aimer graphic with the Z direction distance equal to D in a manner signifying that the object is in focus based on a determination that the object in the field of view is within the depth of field distance ΔD about the distance D, and
- render, on the display unit, the aimer graphic with the Z direction distance equal to D on the display in a manner signifying that the object is not in focus based on the determination that the object in the field of view is not within the depth of field distance ΔD about the distance D.

A system comprising:
- a processing unit to determine a distance D in a z direction corresponding to a three-dimensional coordinate system within a field of view of an imaging device to a current focal plane;
- a display, coupled to the processing unit, whereon an aimer graphic element, with the z-direction equal to D, is rendered;
- wherein the aimer graphic element moves, on the display, in the z-direction with changes in the focal plane;
- wherein the aimer graphic element is rendered:
- in a first manner based on the determination that the distance D is closer to the imaging device than the object and the object is outside the depth of field distance ΔD about the distance D;
- in a second manner based on the determination that the object is within the depth of field distance ΔD about the distance D;
- and
- in a third manner based on the determination that the distance D is further from the imaging device than the object and the object is outside the depth of field distance ΔD about the distance D.
