Navigation System Applying Augmented Reality
First Claim
1. A navigation system which applies augmented reality, comprising:
- a measurement unit including a positioning module that is configured to output a positioning signal associated with positioning coordinates of said navigation system;
a navigation unit coupled to said measurement unit, and configured to perform a path planning algorithm according to the positioning signal, so as to obtain guidance indication for guidance of a user of said navigation system, said navigation unit being further configured to output a navigation signal associated with the guidance indication; and
an image unit coupled to said measurement unit and said navigation unit, and includinga capturing module that is configured to capture a series of planar images of real-world scene,a computation module that is configured to perform an optical flow analysis upon the series of planar images so as to generate an optical flow signal associated with a result of performance of the optical flow analysis and used to obtain the positioning coordinates, said computation module being further configured to perform plane detection processing upon each planar image of the series of planar images so as to output a registration signal associated with a result of performance of the plane detection processing, andan augmented reality module that is configured to receive the navigation signal and the registration signal, and to perform image registration processing based on the navigation signal and the registration signal, so that the guidance indication is superimposed on the series of planar images of real-world scene for subsequent display.

Abstract
A navigation system includes a measurement unit that outputs a positioning signal associated with positioning coordinates, a navigation unit that obtains guidance indication and that outputs a navigation signal, and an image unit that includes a capturing module capturing a series of planar images, a computation module and an augmented reality module. The computation module generates an optical flow signal for obtaining the positioning coordinates, and further outputs a registration signal. The augmented reality module performs image registration processing based on the navigation signal and the registration signal, so that the guidance indication is superimposed on the series of planar images of real-world scene for subsequent display.
