The invention provides an outdoor
mixed reality illumination compensation method and
system based on multi-source environment
perception and real-time
weather data, and the method comprises the steps: obtaining multi-
source data: providing
original data of'space-time reference + environment characteristics' for all subsequent illumination calculation, solving the problems of incomplete coverage and insufficient precision of a single
data source (such as only a camera), and obtaining the multi-
source data; the data is a data basis for real-time illumination compensation; main
light source resolving: the'spatio-temporal data 'is converted into'virtual main
light source parameters' through a physical
algorithm, it is ensured that the direction and intensity of a virtual main
light source (sun / moon) are completely consistent with those of the real world, and the problems of'shadow direction error 'and'
illumination angle splitting' are solved; through GPS space-time positioning, network weather API data and local visual sensor fused illumination compensation, a real-time environment illumination shadow relationship matches a
virtual world with a real world, a more immersive
mixed reality experience is presented, and a split feeling is reduced.
