- capturing scene information at different times based upon a field of view of an image capturing device;
analyzing different targets existing in the scene information being captured;
comparing positions of the same one of the targets captured at different times, wherein the target that is in a specific region in the field of view and moving toward the image capturing device is classified as a type A target, otherwise, the target is classified as a type B target;

Abstract
A scene analysis method is applied to a visual navigation device. The scene analysis method includes the steps of capturing scene information at different times based upon the field of view of an image capturing device; analyzing different targets existing in the captured scene information; comparing each one of the targets captured at different times to classify the target, wherein the target that is in a specific region in the field of view and moving toward the image capturing device is classified as a type A target; otherwise the target is classified as a type B target. When the visual navigation is installed on a vehicle, a protection procedure such as a procedure of avoiding an obstacle is initiated when a type A target is detected, so that the vehicle is automatically prevented from potential accidents.
