Real-time digital geological record system for engineering side slope

Abstract

The invention relates to a real-time digital geological record system for an engineering side slope. The system comprises a computer and two photographic devices, wherein the two photographic devices are of the same type, have the same parameters and are connected with the computer through data lines; the computer comprises a photographic device control module, an image analyzing module, an attitude calculation and graph chart module and a three-dimensional side slope grid construction module. All work including shooting the image of the side slope, storing the image of the side slope to the computer, analyzing the subsequent image, drawing a graph chart and the like is completed on a side slope acquisition site so as to achieve very good instantaneity; one computer synchronously controls the parameters of two digital cameras, so that the parameters of the two digital cameras are completely identical, the image analyzing accuracy is greatly improved, all the work is rapidly completed on the site, the loss caused by the missing of the image is completely avoided, and the problems about omission of the side slope image and the like can be immediately solved on the site if being found, and the reliability and the efficiency are high.

Description

technical field [0001] The invention belongs to photogrammetry technology, and is mainly applied to various engineering slope fields such as water conservancy, hydropower, transportation, mines, etc., and specifically relates to a real-time digital geological recording system for engineering slopes applied to geological recording of engineering slopes. Background technique [0002] The engineering slope geological catalog is to collect the geological data of the slope, survey and map the slope, find out the geological elements of the slope, and draw the corresponding geological maps. The design of slope control and the safe operation of the project are of great significance. There are currently two methods for geological cataloging of engineering slopes: [0003] The first is the traditional cataloging method, that is, engineers and technicians use measuring instruments such as tape measure, total station or GPS positioning device to measure the points that need to be surve...

Problems solved by technology

Although the digital method has made great progress compared with the traditional method, there are still the following problems, which limit the use and development:

[0004] Unable to solve the problem of drawing on site: the digital camera image and the processing program are not well integrated. It is often necessary to bring the digital camera back to the room for manual processing, and then return to the slope for on-site verification, so the real-time performance is not strong;

[0005] There are also some problems with a camera taking two shots: if a fixed-focus lens is used, there will be special requirements for the distance of the camera; if a zoom lens is used, the focal length of the two shots will be inconsistent, and the image resolution accuracy will be affected;

[0006] In addition, the LCD screen of a digital camera is generally relatively small, and it is inconvenient to view the overall view of the slope image. In extreme cases, such as the digital camera is shot on site, and due to unknown reasons indoors, the digital photo is damaged and needs to be reworked and taken again. , affecting work efficiency
