Normalized differential vegetation index automatic measuring vehicle

Abstract

The invention provides a normalized differential vegetation index (NDVI) automatic measuring vehicle comprising a vehicle body in which a control circuit board is disposed. The control circuit board is provided with a central processor, a GPS module, an NVDI module, and a wireless communication module. The central processor is connected with the GPS module, the NVDI module, and the wireless communication module. The GPS module is used for acquiring the positional information of the measuring vehicle and sending the positional information to the central processor. The NVDI module is used for acquiring optical signals and sending the optical signals to the central processor. The central processor computes the NDVI by using an NDVI computational formula according to the optical signals and sends the NDVI and the positional information to a ground station terminal. The NDVI automatic measuring vehicle, by combining a measuring vehicle with NDVI measurement and using the advantages of small size, flexible movement, good off-road performance, and convenient operation of the measuring vehicle, may easily and rapidly acquire the vegetation index and provides correlative data for accurate farm crop nitrogen nutrition diagnosis.

Description

technical field [0001] The invention relates to the technical field of field information collection, in particular to an automatic normalized vegetation index measurement vehicle. Background technique [0002] In recent years, spectral testing has become a research hotspot in field information collection at home and abroad due to its advantages of simplicity, rapidity, high precision and non-destructive testing. The Normalized Difference Vegetation Index (NDVI) has become the main quantitative analysis tool for regional vegetation change research because of its excellent ability to express vegetation information and strong anti-interference ability in the process of data extraction and processing. [0003] Existing devices for measuring normalized difference vegetation index are basically passive measuring devices, which are difficult to popularize due to their complex structure, heavy weight, high value and difficult operation. Excessive dependence on sunlight, affected by...

[0003] Existing devices for measuring normalized difference vegetation index are basically passive measuring devices, which are difficult to popularize due to their complex structure, heavy weight, high value and difficult operation

Excessive dependence on sunlight, affected by the weather, even in sunny weather, weather changes will affect the detection results, and the height of the detector to the vegetation is fixed, which brings a lot of inconvenience to the surveyors, and the measurement Accuracy is greatly affected by human factors
