Pose-based control using 3D information extracted within an extended depth of field

Abstract

Systems and methods for gesture-based control using three-dimensional information extracted within an extended depth of field are described. The system includes a plurality of optical detectors coupled to at least one processor. The plurality of optical detectors images the body. At least two optical detectors of the plurality of optical detectors include wavefront encoded cameras. The processor automatically detects a pose of the body, wherein the pose includes a momentary state of the body. The detection involves gathering gesture data for only a moment of the gesture and excluding the use of background data in the detection of the gesture. The pose data includes focus-resolved position data of the body relative to a neutral position which is an absolute position and orientation in space, wherein the position data is three-dimensional information. The processor translates the gesture into a gesture signal and uses the gesture signal to control components coupled to the processor.

However, two side effects limit the utility of this technique

First, the sensitivity of the imaging system is reduced by a factor equal to the square of the ratio of the inner and outer diameters of the pupil

Second, the maximum spatial frequency response is reduced by a factor equal to the ratio of the inner and outer diameters of the pupil, which limits resolution and contrast in the image
