Problems solved by technology

However, most companies only use technologies such as satellite images to simulate indoor surveys, or use Google Earth to assist in the realization of indoor surveys, and do not organically combine indoor surveys with field surveys to achieve indoor and outdoor linkage.

Embodiment Construction

[0041] Such as figure 1 As shown, the present invention provides a field survey method for indoor and outdoor linkage, which is characterized in that it includes the steps:

[0042] S1. Loading a geographic information database, the geographic information database includes elevation data, high-definition image data, and geographic element information;

[0043] S2. Combining the elevation data with high-definition image data, performing three-dimensional terrain modeling, and generating a pyramid data model;

[0044] S3. Generate a terrain network according to the elevation data in the pyramid data model, and perform texture rendering on the terrain network through high-definition image data and geographic element information to construct a realistic 3D terrain scene;

[0045] S4. Simulate the flight reconnaissance in the constructed three-dimensional terrain scene, and generate a reconnaissance report, the reconnaissance report includes at least one of the flight path, flight...

Abstract

The present invention provides an indoor and outdoor linked field survey system and method thereof, comprising steps: S1, loading a geographic information database, the geographic information database includes elevation data, high-definition image data, and geographical element information; S2, combining the elevation data with the high-definition image Data are combined to carry out 3D terrain modeling and generate a pyramid data model; S3. Generate a terrain network based on the elevation data in the pyramid data model, and render the terrain network through high-definition image data and geographic element information to construct a realistic 3D terrain scene ; S4. Simulating the flight survey in the constructed three-dimensional terrain scene, and generating a survey report; S5. Conducting field survey according to the survey report, collecting field survey data, updating it into the geographic information database, and repeating steps S1 to S3. The invention updates the three-dimensional terrain scene in real time through field survey data, which reduces the number of field surveys to a certain extent.

Description

technical field [0001] The invention relates to the field of petroleum seismic exploration, in particular to an indoor and outdoor linkage field survey method and system thereof. Background technique [0002] Before field production and construction in seismic exploration, it is necessary to conduct field surveys to understand the basic situation of the exploration work area: topography, human conditions, factories, mines, villages, railways, bridges, high-voltage lines, fish ponds, rivers, etc., as well as lithological occurrences near the surface. Lu et al. carried out targeted observation system design and production and construction scheme design according to the situation of the work area learned during the survey. [0003] Traditional field surveys are mainly based on field surveys. Several surveys and on-site measurements are required from design to construction. It is very difficult to conduct site surveys on complex surfaces such as mountains, and wastes a lot of ma...
