Methods and apparatus to calibrate and/or validate stereoscopic depth sensing systems

An apparatus comprising:

• at least one memory including instructions;
• and
• at least one processor to execute the instructions to:
• generate a first image for a first image sensor based on a position and orientation of a display screen relative to the first image sensor;
• generate a second image for a second image sensor based on the position and orientation of the display screen relative to the second image sensor, first content in the first image to be shifted relative to corresponding second content in the second image by a shift amount, the shift amount based on a target depth to be tested;
• cause the first and second images to be presented on the display screen;
• and
• calibrate the first and second image sensors based on a difference between the target depth and a measured depth, the measured depth based on an analysis of the first and second images as captured by the first and second image sensors when the first and second images are presented on the display screen.

At least one non-transitory computer readable medium comprising instructions to cause at least one processor to at least:

• generate a first image for a first image sensor based on a position and orientation of a display screen relative to the first image sensor;
• generate a second image for a second image sensor based on the position and orientation of the display screen relative to the second image sensor, first content in the first image to be shifted relative to corresponding second content in the second image by a shift amount, the shift amount based on a target depth to be tested;
• cause the first and second images to be presented on the display screen;
• and
• calibrate the first and second image sensors based on a difference between the target depth and a measured depth, the measured depth based on an analysis of the first and second images as captured by the first and second image sensors when the first and second images are presented on the display screen.
