Embodiment Construction

[0038] Such as image 3 As shown, the reflective spatially encoded high-resolution light field imaging device consists of an imaging objective lens 1, a digital micromirror array 2 (hereinafter referred to as DMD), a digital micromirror array controller 3 (hereinafter referred to as DMD controller), and an aperture imaging lens 4 , a two-dimensional array detector 5 and a computer 6.

[0039] Among them, the imaging objective lens 1 is provided with an aperture stop 7; DMD2 is conjugate to the object plane, the detection surface of the two-dimensional array detector 2 is conjugate to the aperture stop 7, and each point on the two-dimensional array detector 2 is conjugate to the aperture stop 7. Each point on 7 corresponds one by one;

[0040] Computer 6 sends flipping information to DMD controller 3; Turning information is the order information of each micromirror flipping in DMD2; The sequence information of each micromirror flipping in the present embodiment is represented ...

Abstract

The invention relates to a reflection-type spatial coding high-resolution light field imaging device and method, which can be suitable for being used under main lenses with different numerical apertures, and a main lens imaging system does not need to be specially designed according to the requirements of numerical aperture matching, so that the cost is greatly saved. The imaging device comprisesa computer, a two-dimensional array detector, a digital micro-reflector array, a digital micro-reflector array controller, an imaging objective lens and an aperture imaging lens, image plane space information is sequentially scanned and coded through a digital micro-reflector array, an aperture diaphragm is imaged to a two-dimensional array detector through an aperture imaging lens, the two-dimensional array detector uploads image information to a computer, the computer processes the image information, and therefore high-resolution light field information is obtained.

Description

technical field [0001] The invention belongs to the field of photoelectric imaging, and relates to a reflective space coding high-resolution light field imaging device and method, which can complete the collection and reconstruction of high-resolution light field information. Background technique [0002] The light field imaging system can obtain four-dimensional light field information, and through the collected light field information, use calculation processing to obtain three-dimensional scenes with different viewing angles and different depths. [0003] However, the existing single-camera light field imaging system acquires stereoscopic perspective information at the expense of the spatial resolution of the imaging system. For example, in a non-focusing light field camera, the reference image plane is on the microlens, and the detection surface is located on the focal plane behind the microlens, so its resolution is equivalent to the size of the microlens, and the micro...
