Introduction ============ The following document deals with the calibration of 3D depth sensor chipsets provided by Texas Instruments. It is written in Python 2.7. The calibrations supported are as follows: - Lens Calibration - Common Phase Offset Calibration - HDR Common Phase Offset Calibration - PixelWise Phase Offset Calibration - Non Linearity Calibration - Temperature Calibration Calibration is a complex process, an advanced operation that only needs to be performed occasionally. Readers are advised to read through this entire section before attempting calibration.
