Problems solved by technology

If the pose estimate doesn't exactly match the user's movement, what the user sees doesn't correspond to what his vestibular system is telling his brain, with the risk of making him sick (halo simulator)

Embodiment Construction

[0030] The subject matter is now described with reference to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of subject matter. It is understood that the subject embodiments may be practiced without these specific details.

[0031] According to a non-limiting embodiment of the present disclosure, there is provided a method of determining the pose of an immersive content rendering device by associating motion perception with visual perception. Absolute attitude sensors and differential attitude sensors are associated with a frame of reference in which the attitude is estimated and the device, respectively. In the initialization phase, the initial pose is determined from the absolute pose sensor. Data from at least the absolute attitude sensor and optionally data from the differential attitu...

Abstract

The present disclosure relates to methods, apparatus or systems for determining a final pose (21) of a rendering device. An initial pose is associated with the rendering device. A module (25) determines an intermediate pose (26) according to data from absolute pose sensors (23) and / or differential pose sensors (22). A module (27) determines the final pose (21) according to, first, a difference between the intermediate pose (26) and the initial pose information, second, the data from differential pose sensors (22), and third an evaluation of the visual perception of movements for current images(24) displayed on the rendering device.

Description

technical field [0001] The present disclosure relates to the field of determining the pose of a rendering device by correlating data from absolute and differential pose sensors with a visual perception of a current image displayed on the rendering device. The rendering device is, for example, a smartphone, a tablet, or a head-mounted display (HMD). Background technique [0002] Methods for estimating the pose of an object are diverse. These methods aim to determine the position and orientation of an object in a frame of reference as accurately as possible. The term "pose" collects measurements of an object's position (3 degrees of freedom) and the object's orientation (3 degrees of freedom) in three-dimensional space. So attitude is a six-dimensional measurement. Two types of sensors can be used to estimate the pose of an object: an absolute pose sensor and a differential pose sensor. The sensors help determine at least one of the six dimensions of pose. [0003] Absolu...
