Embodiment Construction

[0025] The present invention will be described in detail below in conjunction with the accompanying drawings. It should be pointed out that the described embodiments are only considered for the purpose of illustration and not limitation of the present invention.

[0026] According to the present invention figure 1 Schematic diagram of the acquisition method of the same field of view multi-spectral video stream, as shown in the figure: the video stream is collected by combining the inter-field stroboscopic active infrared light source; the different fields of the video stream are controlled individually by extracting the field signal in the video stream; Separation step: separate the captured video streams to obtain video streams with different spectra in the same field of view.

[0027] In the separation step, the video stream is separated by extracting field signals in the video stream to generate video streams with the same field of view and different spectrums.

Abstract

The disclosed new-type acquisition device for same-view-field multi-spectrum video flow comprises: a power device, an IR light source, a camera system, and a video separation device. This invention combines PR technology to overcome light effect on the recognition system, and improves location precision greatly.

Description

technical field [0001] The invention relates to the fields of electronic information, signal processing and pattern recognition. In particular, it relates to a video signal acquisition device using a single camera to separate multispectral video streams in the same field of view and a processing method for eliminating background interference and light influence. Background technique [0002] In the field of pattern recognition, the influence of complex background on the detected object has always been an important reason for the low detection rate. How to separate the complex background from the foreground object to be detected in a simple and efficient way and finally eliminate the complex background has always been a very difficult but very meaningful topic. On the other hand, in the actual daily use environment, a variety of ambient light sources and variable light exposure have brought great difficulties to the recognition system. In order to achieve the best recogniti...
