全景摄像机的原理与进展

全景摄像机已经发展到高清、网络化。目前多见的是如下4种:鱼眼全景、多镜头拼接全景、反射式全景、双鱼眼全景。四种全景摄像机的发展与技术各有特点:鱼眼全景,最早出现,技术最成熟简单;多镜头拼接全景,可以实现超高像数图像,但是图像边缘融合、整体白平衡等有待改善;反射式全景,采用反射式光学,弥补了鱼眼全景四周图像解析度不高的缺点;双鱼眼全景,鱼眼和多镜头技术的结合,可实现水平垂直360度图像拍摄。

Principle and progress of panoramic camera

Panoramic camera has been developed to be HD and networking. There are four kinds of commonly used panoramic cameras: fish-eye panorama, multi-camera stitching panorama, reflective panorama, and double-fish-eye panorama. They have different developing histories and characteristic technical traits. As the first panorama camera, the fish-eye is the most technologically simple and mature.The multi-camera stitching can implement ultrahigh pixel imaging, but the image edge fusion and the overall white balance need to be improved. The reflective panorama employs reflective optics to compensate the low image resolution of the fish-eye panoramic camera. A combination of the double-fish-eye, fish-eye, and multi-camera technology enables the 360-degree horizontal and vertical imaging.
