Learning from high quality depth measurements

摘要

A depth camera computing device is provided, including a depth camera and a data-holding subsystem holding instructions executable by a logic subsystem. The instructions are configured to receive a raw image from the depth camera, convert the raw image into a processed image according to a weighting function, and output the processed image. The weighing function is configured to vary test light intensity information generated by the depth camera from a native image collected by the depth camera from a calibration scene toward calibration light intensity information of a reference image collected by a high-precision test source from the calibration scene.

主权项

1. At an image processing module of a computing device compatible with a depth camera, a method of calibrating the depth camera, the method comprising:
receiving from the depth camera a native image including test light intensity information useable to derive a native depth map for a calibration scene; receiving from a high-precision test source a respective reference image taken from a same perspective as the native image and including calibration light intensity information useable to derive a reference depth map for the calibration scene independently from the native depth map; and fitting a weighting function to vary test light intensity information toward the calibration light intensity information for the calibration scene, the weighting function configured to scale light intensity information for a plurality of raw images received by the depth camera during a subsequent operation mode wherein the depth camera is operated independently from the high-precision test source.
