Mobile terminal intelligent foundation pit monitoring system and method based on photogrammetry

Abstract

The invention belongs to the field of foundation pit monitoring, and particularly relates to a mobile terminal intelligent foundation pit monitoring system and method based on photogrammetry. The monitoring system is based on a mobile terminal, and comprises a data input and storage module used for inputting data, downloading data from a cloud end and uploading the data; a camera calibration module which is used for obtaining interior and exterior orientation elements of the camera and adjusting shooting attributes of the camera; a picture screening and processing module which is used for carrying out picture gray scale, size and light sensation processing, picture feature extraction, feature matching and picture splicing; a picture analysis module which is used for calculating data, obtaining internal and external orientation elements and target point coordinates, and judging result rationality; a database which is used for storing and providing data; and a cloud artificial intelligence technology module which is used for being linked with a client database and providing cloud information and artificial intelligence analysis data. The foundation pit safety monitoring system can achieve the function of quickly monitoring the foundation pit safety, effectively save the foundation pit monitoring time, save the management cost, improve the monitoring effect and guarantee the foundation pit construction safety.

Description

technical field [0001] The invention belongs to the field of foundation pit monitoring, and in particular relates to a mobile terminal intelligent foundation pit monitoring system and method based on photogrammetry. Background technique [0002] With the rapid development of my country's economy, the number of construction projects is increasing, and the scale of construction is also increasing. For this reason, engineers need to design various schemes to protect foundation pits, so as to avoid unstable slopes from collapsing and slipping, threatening the lives and property of the people and causing economic losses to the country. [0003] In recent years, with the rapid development of close-range photogrammetry technology, it has gradually become a new type of non-contact measurement method. Compared with traditional monitoring methods, close-range photogrammetry technology has the advantages of instantly obtaining the geometric and physical information of the measured obj...

AI Technical Summary

Problems solved by technology

However, due to the high price, complicated operation, and poor portability of the dedicated measurement camera, the traditional close-range photogrammetry device has more environmental constraints and poor popularity, which limits the development and application of close-range photogrammetry technology in the field of foundation pit monitoring.

In addition, the existing close-range photogrammetry configurations are generally independent measuring equipment or a computer-measuring equipment linkage system, and the computing power is limited, lacking cloud databases, lacking cloud intelligent dynamic analysis capabilities based on big data, and unable to realize the dynamic analysis of big data.
