摘要： In embodiments of a camera-based input device, the input device includes an inertial measurement unit that collects motion data associated with velocity and acceleration of the input device in an environment, such as in three-dimensional (3D) space. The input device also includes at least two visual light cameras that capture images of the environment. A positioning application is implemented to receive the motion data from the inertial measurement unit, and receive the images of the environment from the at least two visual light cameras. The positioning application can then determine positions of the input device based on the motion data and the images correlated with a map of the environment, and track a motion of the input device in the environment based on the determined positions of the input device.

摘要： A source wireless fingerprint is associated with a source image. One or more eligible cataloged wireless fingerprints having a threshold similarity to the source wireless fingerprint are found. Similarly, one or more eligible cataloged images having a threshold similarity to the source image are found. A current location of a device that acquires the source wireless fingerprint and source image is inferred as a chosen cataloged location of a chosen eligible cataloged wireless fingerprint and a chosen eligible cataloged image.

摘要： Embodiments that relate to communicating to a user of a head-mounted display device an estimated quality level of a world-lock display mode are disclosed. For example, in one disclosed embodiment a sensor data is received from one or more sensors of the device. Using the sensor data, an estimated pose of the device is determined. Using the estimated pose, one or more virtual objects are displayed via the device in either the world-lock display mode or in a body-lock display mode. One or more of input uncertainty values of the sensor data and pose uncertainty values of the estimated pose are determined. The input uncertainty values and/or pose uncertainty values are mapped to the estimated quality level of the world-lock display mode. Feedback of the estimated quality level is communicated to a user via device.

摘要： Embodiments related to mapping an environment of a machine-vision system are disclosed. For example, one disclosed method includes acquiring image data resolving one or more reference features of an environment and computing a parameter value based on the image data, wherein the parameter value is responsive to physical deformation of the machine-vision system.
