Abstract

A technical method for single-picture photographic measurement of an underground pipe well comprises the following steps: 1, a single person or two persons operate, a CCD (Charge Coupled Device) camera lens or a camera with WIFI (Wireless Fidelity) is connected through a mobile phone tablet, meanwhile a light source and a laser are switched on, a probe rod is placed in the well to perform photographic processing and camera shooting and collect a picture; and 2, collected picture data are processed by use of APP software of a mobile phone terminal to obtain the pipeline branch direction, the number of branches, the number of pipe block holes, the number of cables, the pipe diameter size, the burial depth, the well chamber size and the pipe ditch size.

Description

1. Technical field

[0001] The invention belongs to a tube well measurement method in urban underground pipeline investigation. 2. Technical Background

[0002] In the investigation of urban underground pipelines, the tube well measuring instruments and equipment are lagging behind. The data inside the well chamber is mainly collected through the traditional working method in which surveyors go down the well with measuring instruments such as steel rulers. Using this working method is labor-intensive and the operation is highly dangerous. , Underground pipeline space measurement urgently needs low-cost, intelligent, automated, portable, and high-efficiency underground pipe well measurement products. 3. Contents of the invention

[0003] A technical method for underground tube well photogrammetry, ①Single or two-person operation, use the CCD lens or camera with WIFI to connect through the mobile phone tablet, turn on the light source and laser at the same time, put the detec...
