High-resolution light field system based on optical framing light field camera and imaging method

The invention provides a high-resolution light field system based on an optical framing light field camera and an imaging method. The high-resolution light field system comprises a main objective lens, a semi-transparent and semi-reflective prism, a micro lens array, an image sensor, a controller and an LCD screen. The light is split by the semi-transparent semi-reflective prism, a four-dimensional light field is cut into a plurality of two-dimensional slices by adopting a Fourier slice theorem through a micro-lens array and a synthetic aperture technology; each image is fused with the blank scene image for the first time to correct the angle installation error and improve the spatial resolution, and then multiple frames of slices are fused for the second time to improve the angular resolution so as to obtain the target scene image, thereby achieving the functions of weakening the aliasing defocusing degree in the imaging process, improving the light field imaging resolution and enhancing the signal-to-noise
