Abstract

The invention discloses a bionic compound eye image acquisition device. The bionic compound eye image acquisition device comprises a visual experiment table, a small eye system, an image sensor, a zoom lens and a data processing system; the small eye system comprises a plurality of small spectacle lenses, the plurality of small spectacle lenses are arranged in a matrix and distributed on a spherical surface with a set curvature radius, and a convex spherical surface of the small eye system faces a picture to be imaged; the image sensor is fixed on the visual experiment table and is positionedon the concave spherical surface side of the ommatidium system; the zoom lens is connected with the image sensor, and the center of the zoom lens is opposite to a small spectacle lens located in the center of the small eye system; and the image sensor is connected with the data processing system. According to the method, the problem that the compound eye spatial resolution is too low due to the small eye size in a traditional compound eye model is solved, meanwhile, the space of the image sensor can be fully utilized, and the system cost is reduced.

Description

technical field [0001] The invention relates to compound eye imaging technology, in particular to a bionic compound eye image acquisition device. Background technique [0002] Compound eye imaging technology is an innovative and interdisciplinary emerging research direction integrating biology, optoelectronics, informatics and other disciplines. The insect compound eye vision system has the characteristics of large field of view and high detection sensitivity of moving targets, so it has advantages that other imaging methods cannot match in some military and civilian applications. [0003] In recent years, precision instruments have developed towards low energy consumption, small size, and high intelligence. Today's electronic devices and mechanical devices have been microfabricated. However, the bottleneck in realizing the miniaturization of systems such as smart weapon identification and micro air vehicle identification lies in the design of micro-optical systems. The t...
