Abstract

Methods, apparatuses, and systems are described for positional tracking (PT) in Augmented Reality (AR) applications. The method may include creating different images for AR preview and PT applications. In some cases, the PT information utilizes key point information. The AR preview and the PT images may be generated simultaneously using time division, space division, split timing, or any combination thereof. This may result in PT with significantly less motion blur. Accordingly, the PT will be more robust, and there will be more good frames available for key components of a PT algorithm (i.e., using visual PT to calibrate the biases of an inertial measurement unit). Thus, the methods and apparatus of the present disclosure may enable more effective management of the trade-off between motion-blur, noise and resolution for PT.

Dependent claims

An apparatus comprising:

an inertial measurement unit (IMU) configured to measure at least one of motion or orientation of the apparatus;
a processing unit receiving from the IMU the at least one of motion or orientation of the apparatus;
an image sensor periodically transmitting to the processing unit a first image and a second image, wherein the first image includes pixels of a first group each exposed with a corresponding exposure time period that is determined by the processing unit at least based on the measured at least one of motion or orientation of the apparatus received from the IMU, and wherein the second image include pixels of a second group each exposed with a corresponding predetermined exposure time period.
