Embodiment

[0038] In this embodiment, we take the reflection data of crop canopy leaves collected by the optical sensing system of the vehicle system as an example to describe in detail a method for improving the dynamic measurement of the vehicle system based on multiple dimensions in the present invention.

[0039] 1. Use the vehicle-mounted system to quickly collect the spectral data of the crop canopy leaves along the direction of the crop row in the field, and use the configured GPS positioning system to obtain the vehicle's coordinate position in real time, the speed of position information collection and the spectral data of the crop canopy leaves The acquisition speed is matched, and the spectral information of the canopy leaves is matched with the GPS position information to obtain a set of discrete multidimensional data, which is recorded as (Pi, Xi, Yi), and i is the number of data, i=60. The experimental data is represented by a matrix as shown in Form 1:

Abstract

The invention relates to a method for improving dynamic measurement for a vehicle-mounted system based on a composite dimension, belonging to the technical field of space remote-sensing analysis. The method disclosed by the invention comprises the following steps of: obtaining the biological information space distribution condition of the tested area by virtue of the vehicle-mounted system to form a corresponding matrix, performing interpolation processing on the matrix, performing fixed-point sampling on the tested area, performing laboratory analysis on a sample, determining the exact value of the biomass of the sample, and performing the same interpolation processing on the sample at first; and then performing comparison and analysis on the vehicle-mounted measurement result and the fixed-point sampling measurement result, so as to obtain the accuracy of vehicle-mounted dynamic measurement; and finally adjusting the acquisition strategy of the vehicle-mounted system via an evaluation, so as to improve the dynamic measurement result of the vehicle-mounted system. The method can be used for directly modelling, analysing and mapping data, as well as has low requirements on configuration, low algorithm redundancy, fast response speed, low cost, and good algorithm rationality and software platform compatibility.

Description

technical field [0001] The invention relates to a dynamic measurement method for improving a vehicle-mounted system based on composite dimensions, and belongs to the technical field of space remote sensing analysis. Background technique [0002] The use of remote sensing methods to collect agricultural information has been widely used, and the relevant analysis methods are relatively mature. Common remote sensing methods such as aerial remote sensing, aerospace remote sensing, low-altitude remote sensing and other data collection methods and data analysis methods are not suitable due to their high cost. It is suitable for the use of ordinary farmers. Commonly used remote sensing analysis methods are mostly used for large-scale spatial analysis, and are not suitable for remote sensing analysis of near-earth remote sensing, especially the information collected synchronously during the operation of the vehicle system. Near-Earth Remote Sensing has the characteristics of simple ...
