Visible light and near-infrared imaging visual sensor based on single sensitive device

Abstract

The invention relates to a visible light and near-infrared imaging visual sensor based on a single sensitive device, and belongs to the technical field of visual sensors. The problem that the fusion efficiency is low due to the fact that the existing visible light and near-infrared image fusion process is complex is solved. The sensor comprises a light source, a lens, a packaging shell, a sensitive device, an image processing module, an image storage module, a communication module and a power supply module, and the sensitive device is a circuit formed by combining a control logic module, a silicon-based photodiode array, a single crystal germanium crystal photodiode array and an analog-to-digital converter, and is used for converting visible light and near-infrared light into binary digital signals and outputting the binary digital signals; and a visual sensor using the sensitive device can realize near-infrared and visible light image fusion without a later algorithm, the image fusion efficiency is improved, the problem of low fusion efficiency caused by a complex process of visible light and near-infrared image fusion at present is solved, and the sensitive device can be widely applied to the field of industrial control.

Description

technical field [0001] The invention belongs to the technical field of visual sensors, in particular to a visual sensor based on visible light and near-infrared imaging of a single sensitive device. Background technique [0002] Visible light refers to electromagnetic waves with a wavelength in the range of 380-880nm, and can also refer to electromagnetic waves that can be perceived by the naked eye. Visible light can be intuitive and clearly reflect image information, but it is often not penetrating, and visible light sensors do not have night vision capabilities; Near-infrared light refers to electromagnetic waves with a wavelength in the range of 780-2526nm. Near-infrared light has strong penetrating ability and can work at night, but it cannot reflect the color information of the image; therefore, the application of visible light and near-infrared image fusion technology can make The fused images contain richer and more comprehensive information, and can work in unfavora...
