Embodiment Construction

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

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

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

[0055] The main controller 35 is used to send instructions to the compound eye controllers 1 of the left and right compound eyes, so as to control the left and right compound eyes to carry out laser emissi...

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 flying target detection method, in particular to a moving target three-dimensional trajectory detection method based on a compound eye bionic optics dual-channel smart quantum dot laser system. Background technique [0002] Artificial compound eye (ACE) is an optical system that simulates the structure of insect compound eyes in nature. big purpose. In recent years, foreign researchers have successfully produced artificial compound eye systems with various structures and uses. For example, Luke P. Lee of the University of California, Berkeley, etc. used polymer microlenses, polymer cone tubes and self-aligned waveguides to achieve hemispherical ACE; Ohio State University L.Li et al. made a hemispherical ACE using an optical microprism array. The cross-sectional shape of each ommatidium microprism is calculated, and the imaging of the wide-field scene on the plane detector is realized. [0003] Based on the advantages of th...
