Abstract
of view. It can be applied in virtual reality, smart homes and other fields as
well. A multi-directional reconstruction algorithm for panoramic camera is proposed in
this paper according to the imaging principle of dome camera, as the distortion inevitably
exists in the captured panorama. First, parameters of a panoramic image are calculated.
Then, a weighting operator with location information is introduced to solve the problem
of rough edges by taking full advantage of pixels. Six directions of the mapping model
are built, which include up, down, left, right, front and back, according to the
correspondence between cylinder and spherical coordinates. Finally, multi-directional
image reconstruction can be realized. Various experiments are performed in panoramas (1024×1024) with 30 different shooting scenes. Results show that the azimuth image can
be reconstructed quickly and accurately. The fuzzy edge can be alleviated effectively.
The rate of pixel utilization can reach 84%, and it is 33% higher than the direct mapping
algorithm. Large scale distortion is also further studied.
