Video processing method and device for multispectral detection and multispectral detection terminal

Abstract

The invention discloses a multispectral detection video processing method, which comprises the following steps: receiving a detection instruction, and selecting at least two single-band image acquisition channels from a plurality of single-band image acquisition channels according to the detection instruction; collecting RGB images of the ground and at least two kinds of single-waveband images inreal time; performing exponential operation on the single-band images to obtain exponential grayscale images, and performing color rendering on the exponential grayscale images according to the exponential size to obtain a pseudo-color images; performing superposition processing on the pseudo-color images and the RGB images, and converting the same into a video image for outputting. According to the method disclosed in the invention, a multispectral imaging technology is utilized; a video image in which the rendered image and the RGB images are synchronously displayed is generated, reciprocalreference between the pseudo-color images and RGB images, and a user is enabled to timely and conveniently know about information in a ground environment; the invention further provides a video processing device for multispectral detection and a multispectral detection terminal, and the video processing device and the multispectral detection terminal have the above beneficial effects.

Description

technical field [0001] The present invention relates to the field of multispectral technology, in particular to a video processing method and device for multispectral detection, and a multispectral detection terminal. Background technique [0002] Remote sensing technology is a technology for detecting and identifying targets by sensing electromagnetic waves, visible light, and infrared rays reflected or radiated by targets from a long distance. Aerial photography, for example, is a remote sensing technique. The successful launch of artificial earth satellites has greatly promoted the development of remote sensing technology. Modern remote sensing technology mainly includes information acquisition, transmission, storage and processing. A complete system that completes the above functions is called a remote sensing system, and its core component is a remote sensor that acquires information. There are many types of remote sensors, mainly cameras, TV cameras, multispectral s...

Problems solved by technology

[0003] The current flight equipment equipped with multispectral imaging technology is widely used in remote sensing applications in agriculture, environment, geology, ecology and other industries. Typical multispectral cameras often obtain independent spectral channel data and add auxiliary information through aerial photography of flight equipment. Stored in related storage media such as SD card or U disk. When the flight equipment returns to the ground, the data is exported. It takes a long process of image data processing before it can be used for final analysis, and the real-time performance is poor.
