Abstract

The embodiment of the invention provides an optical detection device. The device comprises an uncovered shell, a main control board, an image compression board, a target identification board, a symmetrical arc sub-eye support structure, and multiple sub-eyes. The main control board, the image compression board and the target identification board are installed inside the shell. The support structure is fixed on the uncovered side of the shell, and the arc vertexes of the support structure are away from the shell. The sub-eyes are distributed and installed on loop lines on the outer surface of the support structure, and each sub-eye includes an optical lens and an optical detector. The main control board is connected with the optical detectors of the sub-eyes, the target identification board and the image compression board, the sub-eyes are connected with the target identification board, and the target identification board is connected with the image compression board. Through the optical detection device provided by the embodiment of the invention, precise and real-time detection for a large target is realized.

Description

technical field [0001] The invention relates to the technical field of optical reconnaissance detection, in particular to an optical detection device. Background technique [0002] In many application fields such as military and civilian, there is a strong demand for large field of view and high-resolution optical detection systems. However, the traditional visible light reconnaissance detection device is limited by the technical level and the physical principle, and high angular resolution and large field of view cannot be taken into account. Therefore, it cannot reliably realize the needs of airborne or shipborne large-scale target detection and recognition. [0003] At present, the following two methods are mainly used to realize airborne or boatborne large-scale target reconnaissance and detection: [0004] The first type: using a specially designed optical lens with a large field of view to achieve large-scale detection. [0005] Although the existing detection device...
