Camera and sensor augmented reality techniques

摘要

Camera and sensor augmented reality techniques are described. In one or more implementations, an optical basis is obtained that was generated from data obtained by a camera of a computing device and a sensor basis is obtained that was generated from data obtained from one or more sensors that are not a camera. The optical basis and the sensor basis describe a likely orientation or position of the camera and the one or more sensors, respectively, in a physical environment. The optical basis and the sensor basis are compared to verify the orientation or the position of the computing device in the physical environment.

1. A method implemented by a computing device, the method comprising:
obtaining an optical basis generated from image data obtained by a camera of the computing device, the optical basis describing a likely orientation or position of the camera in a physical environment; obtaining a sensor basis generated from sensor data obtained from one or more sensors of the computing device, the sensor basis describing a likely orientation or position of the one or more sensors in the physical environment, the one or more sensors including an inertial measurement unit (IMU) that generates an IMU basis as at least part of the sensor basis; comparing the optical basis and the sensor basis to verify the orientation or the position of the computing device in the physical environment; and responsive to a determination that the optical basis and the sensor basis do not approximately correspond as a result of the comparing, extrapolating a current basis based at least in part on a previous basis of the computing device, the current basis describing a likely orientation or position of the computing device in the physical environment.
