1. A wearable display device comprising:
a frame;
a first sensor and a second sensor spatially distributed on the frame;
one or more displays supported by the frame;
a logic system; and
a storage system comprising
calibration data related to a determined alignment between the first sensor and the second sensor with the frame in a bent configuration the calibration data comprising data determined during manufacturing of the wearable display device and the bent configuration corresponding to a bending moment that would result from the device being worn on a head within an intended range of head widths, and
instructions executable by the logic system to
obtain first sensor data from the first sensor, and obtain second sensor data from the second sensor,
using the calibration data, determine a distance from the wearable display device to a feature based at least upon the first sensor data and the second sensor data;
obtain a stereo image to display based upon the distance from the wearable display device to the feature; and
output the stereo image via the one or more displays.
