Embodiment Construction

[0069] The initialization process has been briefly introduced at the beginning and is shown in figure 1 . In running this process on the application processing unit, a clock rate in excess of 1 GHz is typically required. Therefore, today, object detection applications on mobile devices are only possible for short periods of time due to rapid battery drain.

[0070] According to a preferred embodiment, it is possible to classify objects (visual search process), which is the process of matching the current image with a pre-generated category description, or it is possible to match independent features (feature matching process), which can then ideally be processed by the application The unit is used to run the pose optimization process. Remember that visual search can be based on matching multiple features per image. At the same time, the entire image may be a feature. Both approaches are supported by the present invention.

[0071] According to the invention, both the vis...

Abstract

The invention is related to a wearable information system having at least one camera, the information system operable to have a low-power mode and a high power mode. The information system is configured such that the high-power mode is activated by a detection of at least one object in at least one field of view of the at least one camera.

Description

technical field [0001] The present invention relates to a method and system capable of providing multimedia information to users while reducing battery consumption. Background technique [0002] Standard approach, limitations and existing solutions: [0003] Smartphones, audio guides and similar information systems have become popular in recent years. Augmented reality, as a new user interface paradigm, has made great strides, especially based on computer vision algorithms used for object recognition and pose estimation. Camera-equipped head-mounted displays have been known for some time (eg, US Patent 7,245,273 claim 22). [0004] A major obstacle to the real success of pervasive information systems that can observe the user's surroundings for objects of interest at all times is the high power consumption of image processing algorithms running on application processors or GPUs. This patent describes an innovative system and method that can greatly reduce this problem. ...
