Embodiment Construction

[0030] figure 1 An overview of an embodiment of the invention comprising a computer system 100 and a plurality of sensor nodes in a physical area 102 is shown. figure 1 The computer system 100 and the area are depicted in . The computer system and the area are shown separately by vertical and horizontal double solid lines. Furthermore, the computer system 100 can be divided into an initialization part 110 , an update part 120 , and a presentation part 130 .

[0031] The physical area 102 is covered by at least one sensor node of the plurality of sensor nodes. Sensor nodes can be placed in this area or directed to it, eg for measuring the luminous intensity of a light source. A sensor node is hardware comprising at least one measurement unit for measuring a specific phenomenon type of a spatio-temporal phenomenon. The measurement data may be raw data measured by corresponding sensor nodes. Measurement data 109 may be measurements of one sensor node, or measurements of some...

Abstract

A computer implemented method (200), computer program product, and computer system for updating a data structure reflecting a spatio-temporal phenomenon in a physical area, wherein the spatio-temporal phenomenon is estimated at any location of the physical area by a Gaussian Process with a mean function and a covariance function, the method (200) comprising: storing (210) a data set adapted to represent fixed locations of the physical area, wherein the data set has a mean vector and a covariance matrix according to the Gaussian Process, and wherein the data structure includes the mean vector and the covariance matrix; receiving (222, 224) sensor measurement data of the spatio-temporal phenomenon from at least one sensor node out of a plurality of sensor nodes located at specific arbitrary locations of the physical area; and merging (230, 232, 234, 236, 238) the specific arbitrary locations and the received measurement data into the data structure by using exact recursive Bayesian regression.

Description

technical field [0001] The present invention relates generally to electronic data processing, and more particularly to systems and methods for processing sensor measurement data. Background technique [0002] Measurement, estimation, and prediction of spatiotemporal phenomena such as gas, temperature, or wind are relevant to various use cases. For example, if a spatiotemporal phenomenon such as air pollution in an urban environment exceeds a certain threshold, this spatiotemporal phenomenon may cause harm to the health of local residents. For example, carbon monoxide (CO) and carbon dioxide (CO2) are such gases. Therefore, accurate estimation and forecasting of air pollution in a specific area at a specific time can help prevent harmful situations from occurring. Such space-time phenomena can also be observed in other contexts, such as in the fields of astrophysics, medicine, robotics, human-computer interaction, and geophysics.
