Method and system for generating spatiotemporal model of environmental status based on measurable real-world images

Abstract

The invention discloses an environmental status time-space model generation method and system based on digital measurable images. The method includes: conducting collection through a mobile carrier platform and simultaneously obtaining the environmental parameters and the digital measurable images of a real scenario in each collection position; building a time-space model of the real scenario through the digital measurable images; building a time-space sequence index through exterior orientation elements of the digital measurable images and the collection time, measuring the terrain key points of the scenario according to the digital measurable images and constituting a scenario rough model through the terrain key points; and organizing the environmental parameters according to the built time-space model, adding the marked result to the time-space model by a recording user through the marked pollution feature points and corresponding evaluation information by the digital measurable images, and obtaining outputting and displaying the environmental status time-space model of the real scenario. According to the environmental status time-space model generation method and system, the digital measurable images are regarded as a special environmental parameter used for building the environmental status time-space model, and the measurability of the digital measurable images is fully utilized.

Description

technical field [0001] The invention relates to the field of environmental monitoring and pollution analysis, in particular to a space-time model of the current environmental situation based on measurable real scene images and multiple environmental parameters and an acquisition method thereof. Background technique [0002] With people's increasing attention to environmental issues and the development of environmental sensor technology, the technical parameters of environmental sensors such as sampling frequency and detection accuracy are rapidly improving. At the same time, the volume of environmental sensors is gradually miniaturized, modularized and integrated into mobile carrier platforms. above. In addition to the traditional environmental parameters for general monitoring, spatial information such as real-scene images and position and posture have gradually attracted people's attention, and they are also collected together with environmental parameters as auxiliary dat...

Problems solved by technology

However, the collected information is stored in the industrial computer in the form of text files, which cannot be effectively used

[0003] The currently known environmental status models based on two-dimensional electronic maps or electronic graphics tables cannot intuitively reflect the real scene of the scene, and have high professional requirements for users

In addition, the known models are poor in interactivity, users can only passively receive the information expressed by the model itself, and cannot intuitively add their own evaluation and judgment to the model

Even if some known environmental monitoring technologies introduce real-scene images and related spatial information, they only treat them as independent scene information, and do not apply measurable real-scene images as a special environmental parameter to establish an environmental status model
