A method for calibrating an image capture device comprising: a) for a number of sample devices from a batch: a.1) mounting at least one sample device from a batch for movement through a plurality of orientations relative to a horizontal plane, a.2) for a given orientation, focusing said sample device at a sequence of positions, each position being at a respective focus distance from said device; a.3) recording a lens actuator setting for said sample device at each position; and a.4) repeating steps a.2) and a.3) at a plurality of distinct orientations of said sample device; b) determining respective relationships between lens actuator settings at any given position for distinct orientations from said plurality of distinct orientations and actuator settings at a selected orientation of said plurality of distinct orientations including statistically analyzing the recorded lens actuator settings for said sample devices to determine said relationships; c) recording lens actuator settings for said image capture device to be calibrated at least at two points of interest, each a specified focus distance from said device with said image capture device positioned at said selected orientation; and d) calibrating said image capture device for said plurality of distinct orientations by recording data based on said determined relationships and said recorded lens actuator settings in said device memory. a) for a number of sample devices from a batch: a.1) mounting at least one sample device from a batch for movement through a plurality of orientations relative to a horizontal plane, a.2) for a given orientation, focusing said sample device at a sequence of positions, each position being at a respective focus distance from said device; a.3) recording a lens actuator setting for said sample device at each position; and a.4) repeating steps a.2) and a.3) at a plurality of distinct orientations of said sample device; a.1) mounting at least one sample device from a batch for movement through a plurality of orientations relative to a horizontal plane, a.2) for a given orientation, focusing said sample device at a sequence of positions, each position being at a respective focus distance from said device; a.3) recording a lens actuator setting for said sample device at each position; and a.4) repeating steps a.2) and a.3) at a plurality of distinct orientations of said sample device; b) determining respective relationships between lens actuator settings at any given position for distinct orientations from said plurality of distinct orientations and actuator settings at a selected orientation of said plurality of distinct orientations including statistically analyzing the recorded lens actuator settings for said sample devices to determine said relationships; c) recording lens actuator settings for said image capture device to be calibrated at least at two points of interest, each a specified focus distance from said device with said image capture device positioned at said selected orientation; and d) calibrating said image capture device for said plurality of distinct orientations by recording data based on said determined relationships and said recorded lens actuator settings in said device memory.
