Embodiment Construction

[0029] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below in conjunction with the accompanying drawings and specific embodiments. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0030] Example figure 2 As shown, the high dynamic range imaging method of the InGaAs short-wave infrared camera based on correlated double sampling in this embodiment requires a short-wave infrared integrating sphere as a uniform and adjustable light source and an InGaAs short-wave infrared camera. The short-wave infrared integrating sphere emits uniform light with a spectrum of 800nm-2500nm, which ca...

Abstract

The invention belongs to the technical field of infrared imaging, and relates to a short-wave infrared camera high dynamic range imaging method. The invention discloses an InGaAs short-wave infrared camera high dynamic range imaging method based on correlated double sampling. The method comprises the following steps: setting the digits of original data and HDR data collected by an InGaAs short-wave infrared camera, and determining the HDR multiplying power hdr _ mul _ factor; an HDR threshold value hdr _ th is determined; determining a background response bg of the camera; setting integral time T1 and T2, and judging whether the pixel enters an HDR mode or not according to the integral time and an HDR threshold hdr _ th; and calculating responses of the pixels, and reading the responses ofall the pixels to complete imaging. According to the method, HDR imaging of the short-wave infrared band is achieved based on the related double-sampling function of the InGaAs short-wave infrared camera, the method is efficient and convenient to achieve, the image with higher image brightness and contrast range can be obtained, and the visual effect in the real environment is better reflected.

Description

technical field [0001] The invention belongs to the technical field of infrared imaging, and relates to a high dynamic range imaging method of a short-wave infrared camera. Background technique [0002] In recent years, the rapid development of InGaAs material growth and focal plane preparation technology has led to the progress of InGaAs-based short-wave infrared imaging technology. Short-wave infrared cameras based on InGaAs materials have the advantages of working at room temperature, high detection rate, and good uniformity. They have been widely used in military, medical, industrial, agricultural and other fields, and are widely favored. Short-wave infrared imaging based on InGaAs materials has become a research hotspot in the current imaging field. Compared with medium and long-wave infrared imaging, the imaging scene outline is clearer and has a higher degree of recognition; compared with visible light, it is less affected by atmospheric condensation water and has bet...
