The invention relates to the technical field of wireless sensor network observation, in particular to a comprehensive measurement method for uncertainty in the ground wireless networking observation of an ecological parameter. The measurement method comprises the following steps that: 1) data collection; 2) data preprocessing; 3) constructing a transformation model based on Gaussian process regression; and 4) carrying out the comprehensive measurement of observation uncertainty and upscaling uncertainty. By use of the method, through a Bayes normal form, a comprehensive measurement model for the uncertainty for ground observation and upscaling is put forward, and an uncertainty transferring process is clearly described through a strict mathematical model. The method owns business operationability, and in addition, feedback information can be provided for the arrangement and the optimization of wireless networking so as to meet the realistic demands of remote sensing quantitative product verification and regional ecological model driving for the uncertainty measurement of an ecological parameter reference diagram.
Description
technical field [0001] The invention relates to the technical field of wireless sensor network observation, in particular to an uncertainty comprehensive measurement method in the ground wireless networking observation of ecological parameters. Background technique [0002] Benefiting from the vigorous development of the Internet of Things technology, the ground wireless networked observation of ecological parameters has become a reality. Compared with traditional manual measurement methods, ground wireless networked observations have the advantages of spatial distribution and time continuity, and can describe the spatial heterogeneity and temporal variation of ecological parameters in detail. Based on the ground wireless networked observation data, the high-resolution ecological parameter reference map obtained by upscaling with a certain conversion model has been widely used in remote sensing quantitative product verification, regional ecological model driving and other fi...
