TURNING DETERMINING METHOD FOR ASSISTING NAVIGATION AND TERMINAL DEVICE THEREOF
First Claim
1. A global positioning system (GPS) terminal device, for providing a navigation display when the GPS terminal device is moving along a curved path and when GPS information is not available, the GPS terminal device comprising:
- a storage unit, for storing at least one map information;
an image capture unit, for capturing a plurality of background images upon the GPS terminal device moving along the curved path; and
a processing module, electrically connected to the storage unit and the image capture unit, for determining a turning motion according to the map information and the background images so as to generate turning determining information, and the processing module providing the navigation display in accordance with the turning determining information.

Abstract
The present invention relates to a turning determining method for assisting navigation. The navigation method provides a navigation display while a GPS terminal device is moving along a curved path and when GPS information is not available, the navigation method captures a plurality of background images upon the GPS terminal device moving along the curved path to determine a turning and maintain navigation frames. Then the background images are processed to obtain the deviation direction of the reference point by subtraction and comparison, or to capture specific object image as reference. The navigation method utilizes a GPS terminal device comprising an image capture unit to capture images.
