Reduced bandwidth stereo distortion correction for fisheye lens in head mounted display

摘要

A system and method for providing a stereo depth camera for a head mounted display system with less memory and / or processing power required.The stereo depth camera may include left and right cameras spaced apart from each other by a certain distance.Each of the left camera and the right camera may be tilted outwardly from the front direction of the head mount display system to a non-zero angle to provide a relatively wide view for the stereo depth camera.Each of the left and right cameras may include a camera sensor array and a camera lens disposed in front of the camera sensor array.Each of the camera lenses may include an optical axis laterally shifted toward the center of the support structure from the center of the camera sensor array associated with the center of the left camera lens to substantially the scene center or the main point.
