Image Perspective Conversion Method by Converting Coordinates of Polygonal Sub-regions and System Thereof

An image perspective conversion system comprising:

• an image capturing device configured to capture a first image;
• a memory configured to save data of a world coordinate system;
• a processor coupled to the image capturing device and the memory and configured to process the first image;
• and
• an image output device coupled to the processor and configured to output a second image;
• wherein the processor partitions a predetermined region on the first image into a plurality of polygonal sub-regions, acquires a plurality of first coordinates of the plurality of polygonal sub-regions, converts the plurality of first coordinates into a plurality of second coordinates according to the world coordinate system, and interpolates a plurality of pixels among the plurality of second coordinates for generating the second image, and the first image and the second image are two images with different angles of view.
