WALKING ASSISTANCE SYSTEM AND METHOD
First Claim
1. A walking assistance device comprising:
- a storage system;
a processor;
one or more programs stored in the storage system, executable by the processor, the one or more programs comprising;
an image obtaining module operable to obtain an image captured by a camera, the image comprising a distance information indicating distances between the camera and objects captured by the camera;
an image analysis module operable to determine whether one or more objects appear in the captured image;
a model creating module operable to create a 3D scene model according to the captured image and the distances between the camera and objects captured by the camera when one or more objects appear in the captured image;
a detecting module operable to determine whether one or more specific objects appear in the created 3D scene model, and further determine that one or more obstacles appear when no specific object appears in the captured image; and
an executing module operable to create an obstacle audio file based on the determined one or more obstacles, and further output the created obstacle audio file through an audio output device, to prompt one or more obstacles appear ahead.

Abstract
An example walking assistance method includes obtaining an image captured by a camera. The image includes distance information indicating distances between the camera and objects captured by the camera. Next, the method determines whether one or more objects appear in the captured image. If yes, the method then creates a 3D scene model according to the captured image and the distances between the camera and objects captured by the camera. Next, the method determines whether one or more specific objects appear in the created 3D scene model, and further determines one or more obstacles appear when no specific object appears in the captured image. The method then creates an obstacle audio file based on the determined one or more obstacles, and further outputs the created obstacle audio file through an audio output device, to prompt one or more obstacles appear ahead.
