Title:
最適化された映像合成方法
Document Type and Number:
Japanese Patent JP4642037
Kind Code:
B2
Abstract:
The invention discloses an optimized video stitching method, comprising: inputting predefined pattern images; proceeding with a transformation which combines planar and cylindrical transformation; proceeding with a merging calculation which combines linear difference merging and alpha blending calculation; and proceeding with a horizontal stitching processing by putting the processed images horizontally together into one seamless wide-angle image. The optimized video stitching method according to the invention further comprises a camera position calibration flow comprising: finding a planar matrix by using predefined pattern images; proceeding with a planar transformation of image; proceeding with an image registration by using a block matching method to find out the stitching points on the planar surface; and proceeding with a cylindrical transformation by transforming the stitching points from the planar surface to cylindrical surface.
