Abstract

An image processing method and a system are provided. The image processing method of moving camera comprises the following steps. An image of a road is captured by a first camera unit. A coordinate of the image of an object shown in the image of the road is captured when the image of the object shown in the image of the road is selected. At least an aiming angle of a second camera unit is adjusted according to the coordinate to make the field-of-view of the second camera unit aligned with the object. The image of the object is captured by the second camera unit. The image of the object is enlarged.

Claims

1. An image processing method, comprising:

providing a navigation route of a transportation device and the image of a landmark corresponding to the navigation route;

capturing the image of a road by a first camera unit;

determining whether the image of the road shows the image of the landmark when the transportation device deviates from the navigation route; and

modifying the navigation route if the image of the road does not show the image of the landmark.

2. The image processing method according to claim 1, wherein in the step of determining whether the image of the road shows the image of the landmark, the image of the landmark is searched by a plurality of searching terms of the image of the landmark.

3. An image processing system configured in a transportation device, wherein the image processing system comprises:

a storage unit configured to store a navigation route and an image of a landmark corresponding to the navigation route;

a first camera unit configured to capture the image of a road; and

a processing unit configured to determine whether the image of the road shows the image of the landmark when the transportation device deviates from the navigation route, and to modify the navigation route if the image of the road does not show the image of the landmark.

4. The image processing system according to claim 3, wherein the processing unit is configured to search the image of the landmark according to a plurality of searching terms of the image of the landmark.
