6 August 2009Research of real-time wide field image merging based on multi-cameras
Wide field images have been widely applied in Visual reality, video compression, transmission and medical apparatus.
The image is usually obtained by using single wide-angle lens such as the fisheye lens or by merging the images scanned
with conventional cameras. The paper proposed a system by placing two cameras at a fixed distance between each other
so the large-scale field of view can be split into small parts and images are obtained synchronously. Because each
adjacent camera has been located fixedly, the corresponding field range of each image is known easily, and a stitching
algorithm based on correlation coefficient of corresponding pixel lists is used to merge the images. As shown by the
experiments, the system proposed in this paper is simple and effective for obtaining wide field image with both high
real-time quality and image resolution.
