Description

technical field [0001] The invention relates to a stereoscopic imaging device and system based on compressed sensing theory, belonging to the technical field of compressed sensing imaging. Background technique [0002] Compressed sensing, also known as compressed sampling, sparse sampling, compressed sensing. As a new sampling theory, it uses random sampling to obtain discrete samples of the signal by exploiting the sparse characteristics of the signal, and then reconstructs the signal through a nonlinear algorithm. Once the compressive sensing theory was put forward, it attracted extensive attention from academia and industry. It has received high attention in the fields of information theory, image processing, earth science, optical / microwave imaging, pattern recognition, wireless communication, biomedical engineering, etc. [0003] In recent years, the use of compressed sensing principles for imaging has greatly improved the imaging quality, especially for infrared imag...
