In recent years, as the core component of visual information acquisition, high-performance intelligent CMOS image sensors have increasingly become critical foundations and technical support for major national scientific and technological research projects such as manned spaceflight, large aircraft,high-resolution earth observation and other aerospace and space exploration fields. The three-dimensional integrated image sensor chip architecture lays the foundation for the construction of an intelligent imaging system. The intelligent bionic image sensor that simulates the mechanism of biological visual perception solves the challenges of perception and processing capabilities brought by the continuous increase in resolution and frame rate. It also has the advantages of large dynamic range, low data redundancy and low power consumption.Based on the analysis of the mechanism of intelligent imaging, this paper investigates the research progress of a variety of bionic CMOS image sensors and analyzes the key technologies of intelligent imaging and recognition.It provides a reference for the commanding heights of CMOS image sensor technology.
