1. A data-holding subsystem holding instructions executable by a logic subsystem to:
- acquire a depth image from a depth camera;
identify an environmental factor invalidating depth information in one or more portions of the depth image; and
output an environmental modification to mitigate the environmental factor.

Abstract
A method of depth imaging includes acquiring a depth image from a depth camera, identifying an environmental factor invalidating depth information in one or more portions of the depth image, and outputting an environmental modification to mitigate the environmental factor.

13. A method of depth imaging, comprising:
-
imaging a scene with a depth camera configured to measure a distance between the depth camera and surfaces in the scene; in a test mode, acquiring from the depth camera a test image in which the scene is exposed with an infrared test light; in a control mode, acquiring from the depth camera a control image in which the scene is not exposed with the infrared test light; and outputting an environmental modification to mitigate an environmental factor identified by comparing the test image to the control image.

14. A method of depth imaging, comprising:
-
acquiring a depth image from a depth camera, the depth camera configured to measure a distance between the depth camera and surfaces in an imaged scene and configured to output the depth image as an indication of such measured distances; modeling a human target imaged by the depth image with a virtual skeleton; responsive to a failure to model the human target with the virtual skeleton, identifying a cluster of invalid depth pixels in the depth image; acquiring a test image from the depth camera while the imaged scene is exposed with an infrared test light; acquiring a control image from the depth camera while the imaged scene is not exposed with the infrared test light; identifying an environmental factor responsible for the cluster of invalid depth pixels based on the cluster of invalid depth pixels, the test image, and the control image; and outputting a communication message for presentation to the human target, the communication message providing information useable by the human target to mitigate the environmental factor. - View Dependent Claims (15, 16, 17, 18, 19, 20)
