Compact high resolution light field camera with double optical path imaging

Abstract

The present invention discloses a compact high resolution light field camera with dual optical path imaging, which comprises a reflective light field imaging light path, a common imaging light path, a light path separation device and a light path switching device. The reflective light field imaging light path is composed of a lens (1001), a concave mirror array (1002) and an image sensor (1008) and is used for collecting a light field image having depth information. The common imaging light path is composed of the lens (1001), a planar mirror (1005) and an image sensor (1008) and is used for collecting a high-resolution two-dimensional image. The light path separation device and the light path switching device are used for realizing separation and switching of the reflective light field imaging light path and the common imaging light path. With the combination of the reflective light field imaging light path and the common imaging light path, the high resolution light field image can be obtained. With the light path separation device and the light path switching device, the camera structure is enabled to be compact.

Description

technical field [0001] The invention relates to the technical field of light field cameras, in particular to a compact high-resolution light field camera with dual optical path imaging. Background technique [0002] Compared with ordinary cameras, light field cameras can realize many new functions, such as: taking pictures first and then focusing, expanding depth of field, extracting depth information, removing occlusions, etc. However, the lens array structure in the light field camera will lead to the problem of low spatial resolution. The image resolution obtained by light field cameras is usually only one-tenth of that obtained by ordinary cameras. This inherent shortcoming becomes the bottleneck of its development. [0003] This problem can be well solved by combining the light field camera with the ordinary camera, which not only realizes many new functions of the light field camera but also improves the image resolution. However, simply putting together an ordinary...

Problems solved by technology

However, simply putting together an ordinary camera and a light field camera requires two sets of independent imaging optical paths, which not only makes the entire system bulky, but also requires two image sensors, which increases the cost; at the same time, because the two sets of optical paths do not share the same The root optical axis increases the difficulty of post-image processing
