    Hi.
    I’m building a Sandbox AR 1800 cm x 1350 cm with a hi-resolution projector (1600×1200 pixels) and mirror. In the first calibration it work very well.
    I have a question about Rawkinectviewer. Is possible to change the range of colors vs distance, because in calibration process is very difficult to see borders in the box when the distance is about 160 – 170 cm (all distances appear in similar blue.

    Thanks.

    You can change the depth range by passing a -depthRange <min depth> <max depth> parameter on RawKinectViewer’s command line. Depth values are not metric distances, however. You should try -depthRange 900 1090 first and see how that works out.

    Alternatively, you can define a base plane interactively, and color everything by distance to that base plane. Flatten the sand surface, and select “Average Frames” from the main menu. Then assign a “Define Depth Planes” tool to two arbitrary buttons say “1” and “2”. Then press “1” a few times to select points from your sand surface, and press “2” once to define a plane approximating all those points. Afterwards, the edges of the box should show up clearly. You can then assign the 3D measurement tool and measure points as usual.

    Hi Oliver.

    Work fine with 800 950 parameter.

    Thank you very much for your help.
