Embodiment Construction

[0052] This method is realized on the flying target detection system based on the compound eye structure of the two-way smart quantum dot. The system uses two compound eyes on the left and right, and each compound eye has the same structure, such as figure 1 (meridian view) and figure 2 (top view); detection system such as image 3 shown.

[0053] The system consists of a main controller 35, a connecting rod 39, a three-axis rotator 36 for the left eye, a three-axis rotator 37 for the right eye, and two compound eyes on the left and right sides. in:

[0054] The left and right compound eyes are installed on the left-eye three-axis rotator 36 and the right-eye three-axis rotator 37 respectively, and the connecting rod 39 is used to connect the left-eye three-axis rotator 36 and the right-eye three-axis rotator 37;

[0055] The main controller 35 is used to send instructions to the compound eye controller 1 of the left and right compound eyes, thereby controlling the left a...

Abstract

The invention discloses a flight object detection method based on double-channel alert quantum-dot compound eye system, and the method is realized in the double-channel alert quantum-dot laser system on the system of component eye bionic optics. The system is mainly composed of a main controller, a connecting rod, a left-eye three-axis revolver, a right-eye three-axis revolver and left and right compound eyes. The method comprises the steps of laser emission, rough tracking, initial positioning, fine tracking and spatial track description. The method has the advantages that active quantum dot laser emission sources and echo detection unit matching small eye channels are constructed in the compound eyes simultaneously, and the wavelength and the intensity are selected so that the compound eyes are adapted to different environments; a double-compound-eye three-axis continuous scanning detection manner is used to solve the problem in the fine tracking precision of a spatial object; and compared with that of a traditional system, the method is more suitable for 3D track detection of the flight object.

Description

technical field [0001] The invention relates to a method for detecting a flying target, in particular to a method for detecting a three-dimensional trajectory of a moving target based on a compound-eye bionic optics dual-path smart quantum dot laser system. Background technique [0002] Artificial compound eye (ACE) is an optical system that simulates the compound eye structure of insects in nature. It replaces the widely used single-aperture optical system with a multi-aperture optical system to achieve miniaturization, light weight, and increased field of view of the entire system. big purpose. In recent years, foreign researchers have successfully produced various artificial compound eye systems with different structures and uses. For example, Luke P.Lee of the University of California, Berkeley, USA, realized a hemispherical ACE by using polymer microlenses, polymer cones, and self-aligning waveguides; The cross-sectional shape of each ommatidium microprism is calculat...
