Embodiment 1

[0029] combine image 3 As shown, the embodiment of the present invention provides a four-band remote video monitoring system with the function of frequency conversion transmission of narrow bandwidth and large image data. The video monitoring system includes a visible light lens, a near-infrared lens, a 3CCD image detector, a near-infrared image detector, an image acquisition and processing system, and a remote computer. Among them, the visible light lens is an independently designed fixed-focus optical lens group that matches the optical parameters of the 3CCD image detector, with a wavelength range of 400nm~700nm and a focal length of 50mm. The near-infrared lens is a self-designed fixed-focus optical lens group that matches the optical parameters of the near-infrared image detector. Its wavelength range is 700nm~1000nm and the focal length is 50mm. The 3CCD image detector is the AT-140CL 3CCD industrial camera of Denmark JAI Company, with 3 channels, effective resolution ...

Abstract

The invention relates to a four-band remote video monitoring system and a data transmission method thereof. The video monitoring system comprises a visible-light lens, a near-infrared lens, a 3CCD (3 charge coupled device) image detector, a near-infrared image detector, an image collecting and processing device and a remote computer. According to the four-band remote video monitoring system and the data transmission method applicable to frequency conversion transmission of a narrow-bandwidth large data stream of the system, under the condition that a network transmission bandwidth is smaller than an image data bandwidth, the smooth transmission of dynamic video data and the lossless transmission of high-definition image data are achieved flexibly; and multi-band motion state estimation and static state spectral characteristic analysis of a dynamic target are facilitated.

Description

technical field [0001] The invention relates to a data transmission method, in particular to a four-band remote video monitoring system and a data transmission method thereof. Background technique [0002] With the rapid development of spectral imaging technology, various spectral monitoring devices are emerging. In the entire detection spectrum range, the visible light spectrum has become the main band of video surveillance due to its high spectral energy and high visibility; in addition, due to the high reflectivity of vegetation to the near-infrared It has a good detection effect on target identification and monitoring. At present, most of the monitoring instruments on the market are for a single detection band, and the detectors used for remote monitoring are often limited to lower resolution due to bandwidth limitations, and the monitoring effect is poor. Contents of the invention [0003] The present invention solves the technical problems in the prior art, and pro...
