Embodiment Construction

[0027] In order to better understand the contents of the present invention, an example is given here.

[0028] The invention discloses a modular night vision imaging camera, which comprises a plurality of identical imaging modules, a central image processing unit and a synchronous control module, each imaging module is connected with the central image processing unit and the synchronous control module, the system structure as attached figure 1 shown.

[0029] The imaging module includes a lens, an image sensor, a synchronous interface, a distortion correction module and an image output module.

[0030] The image sensor is located on the focal plane of the lens, all imaging modules are placed in parallel, and the lens axes of all imaging modules point to the same direction to ensure that the non-directional light emitted by the same target is received by the lens of each imaging module and imaged to the focal plane of the lens. The image sensor located on the focal plane con...

Abstract

The invention discloses a modular night vision imaging camera, which comprises a plurality of identical imaging modules, a central image processing unit and a synchronous control module, and the imaging module includes a lens, an image sensor, a synchronous interface, a distortion correction module and an image output Module, the imaging module uses multiple imaging modules for shooting, converts the photons of each imaging module into charges, and converts them into digital signals, and adds the digital signals of each channel to obtain an enhanced signal. The distortion correction module corrects the digital image signal in real time to eliminate the image inconsistency caused by the difference of lens distortion among the various imaging modules. The invention continuously improves the detection capability of the imaging camera by increasing the number of units, avoids the risk of camera burnout under strong light caused by the multiplication technology, and breaks through the limit caused by photon noise in the multiplication low-light shooting system.

Description

technical field [0001] The invention belongs to the technical field of photoelectric imaging, and in particular relates to a modular night vision imaging camera. Background technique [0002] Existing low-light night vision cameras are divided into image-enhanced low-light night-vision cameras and charge multiplier low-light night-vision cameras. The image-enhanced low-light night vision camera multiplies the photons collected by the optical system through a micro-channel plate, and then couples them to the image sensor to enhance the light intensity signal. The charge multiplication low-light night vision camera first converts light into electric charges, and then completes the charge multiplication on the image sensor, thereby achieving signal enhancement. [0003] There are some limitations in the use of existing low-light night vision cameras, including the fact that the daytime light is too strong to work, and it needs to be used in combination with conventional sensor...
