Embodiment

[0065] Step 1. Construct the wide-baseline multi-array optical detection system structure

[0066] 1.1) Design the installation platform to simulate the installation carrier of the wide-baseline multi-array optical detection system.

[0067] The installation platform includes a 3m×3m main platform frame, and two sub-platforms are designed for multi-angle observation of the observation target. Since the main array optical system 1 installed on the main platform is used to generate a large field of view, and the sub-array optical system 2 is used to obtain other auxiliary information such as depth information, the size of the sub-platform used to install the sub-array optical system 2 will be smaller than The main platform is designed as a frame structure of 1.5m×1.5m.

[0068] In order to realize the precise positioning of the optical sensor 3 during installation, the main platform and the auxiliary platform are provided with scales in the horizontal and vertical directions wi...

Abstract

The invention discloses a wide-base-line multi-array optical detection system which comprises a main array optical system arranged on the lower portion of an airplane body and sub array optical systems arranged on the lower portions of two wings of the airplane. The main array optical system and each sub array optical system comprise a plurality of optical sensors. The invention further discloses a setting method of the wide-base-line multi-array optical detection system, and the target detection requirements of large view field, high resolution, high dynamic and multiple view angles are met at the same time.

Description

technical field [0001] The invention belongs to the technical field of optical detection, and in particular relates to a wide-baseline multi-array optical detection system and a setting method thereof. Background technique [0002] The airborne optical detection system has the characteristics of wide detection range, high resolution and passive detection, and is widely used in air target detection and tracking, ground target search and tracking, battlefield situation awareness, missile incoming warning, auxiliary navigation and take-off landing etc. [0003] The traditional airborne optical detection system currently mainly adopts the pod structure, which has a small observation field of view and less extraction of target information, which can no longer meet the needs of target detection, tracking, identification and situation estimation in complex environments. At the same time, the load constraints of the pod severely limit the improvement of the resolution of the optica...
