Image acquisition device and enhanced vegetation index monitoring system

Abstract

The invention relates to an image acquisition device and an enhanced vegetation index monitoring system. The image acquisition device comprises an image acquisition unit, an image sensor, a controller, a power supply module and a bracket, wherein the image acquisition unit is used for simultaneously and separately acquiring images of a plurality of wavebands; the image sensor is used for converting images acquired by the image acquisition unit into image data and transmitting the image data to the controller; the controller is suitable for storing and transmitting the image data collected and converted by the image sensor; the power supply module is used for supplying power to the image acquisition device for normal work for a long time; the bracket is used for carrying out fixing and position adjustment on the image acquisition device. The enhanced vegetation index monitoring system comprises the image acquisition device, an image receiving device and a data analyzing device, wherein the image receiving device is used for receiving the image data transmitted from the controller; the data analyzing device is used for carrying out analysis and calculation according to the image data received by the image receiving device so as to obtain an enhanced vegetation index value.

Description

technical field [0001] The invention relates to image acquisition and environment monitoring technology, in particular to an image acquisition device and an enhanced vegetation index monitoring system. Background technique [0002] The Enhanced Vegetation Index (EVI) is designed on the basis of the Normalized Difference Vegetation Index (NDVI) by adding blue bands to correct the influence of soil background and aerosol scattering on the Vegetation Index. Enhanced vegetation index is one of the important parameters for remote sensing monitoring of physiological abnormal characteristics of vegetation, vegetation growth and distribution, and farmland drought. [0003] At present, the data sources of remote sensing inversion EVI mainly include satellite remote sensing images and aircraft remote sensing images, but there are many defects: the flight orbit and revisit cycle of the satellite are preset before the satellite launch, and are generally relatively fixed; the cost of air...

AI Technical Summary

Problems solved by technology

[0003] At present, the data sources of remote sensing inversion EVI mainly include satellite remote sensing images and aircraft remote sensing images, but there are many defects: the flight orbit and revisit cycle of the satellite are preset before the satellite launch, and are generally relatively fixed; the cost of aircraft remote sensing is very high. Expensive, poor flexibility, high requirements on weather conditions, and strict airspace control

[0004] In addition, the ground platform is also one of the platforms for the image acquisition device, but the existing ground platforms also have problems of high cost and poor flexibility
