Abstract
A kind of technical method photogrammetric for underground pipe well monolithic, 1. one or two people's operations have the CCD camera lens or camera of WIFI using opening, it is attached by mobile phone plane plate, opens simultaneously light source and laser, detection bar is put into underground, it can photograph, image, acquire picture；2. the APP software using mobile phone terminal handles the image data of acquisition, available line branches direction, numbers of branches, plumber block hole count, cable item number, caliber size, buried depth, well room size, pipe trench width etc..
Description
Technical field
The invention belongs to the methods of pipe well measurement in City Buried Pipeline investigation.
Background technique
The data inside well room are mainly passed through survey by pipe well measuring instrument and equipment lag in City Buried Pipeline investigation
Amount personnel hold the conventional operation mode that the measuring instruments such as steel ruler are gone into the well and are acquired, using this working method labor intensity
Greatly, operation degree of danger is high, there is an urgent need to prices low, intelligent, the automation, portable, high efficiency of underground utilities spatial measurement
Buried pipe well measurements product.
Summary of the invention
A kind of technical method photogrammetric for underground pipe well, 1. one or two people's operations have WIFI using opening
CCD camera lens or camera, be attached by mobile phone plane plate, open simultaneously light source and laser, will detection bar be put into underground, can
To photograph, camera shooting acquires picture；It, can be with 2. the APP software using mobile phone terminal handles the image data of acquisition
Obtain line branches direction, numbers of branches, plumber block hole count, cable item number, caliber size, buried depth, well room size, pipe trench width
Deng.Underground pipe well photogrammetric apparatus, 1. instrument hardware has mobile phone plane plate, the lens camera with WIFI, laser, light source, visits
Measuring staff is composed；2. carrying out WIFI connection to camera by mobile phone plane plate, carry out data transmission；3. by mobile phone plane plate to well
Lower data acquisition, controls picture shooting；4. borehole wall etc. carries out the resolving of picture, existing using mobile phone terminal APP to pipeline to be measured
Coordinate acquisition is carried out to laser point, then coordinate acquisition is carried out to target object both sides to be measured respectively and finally shows the straight of determinand
The shooting distance of diameter and image center to determinand.
Detailed description of the invention
Fig. 1 is underground pipe well photogrammetric apparatus schematic diagram.Fig. 2 is underground pipe well photogrammetric apparatus operation schematic diagram.
Fig. 3 is that the underground pipe well picture of acquisition resolves schematic diagram.
Specific embodiment
A kind of technical method photogrammetric for underground pipe well, 1. one or two people's operations have WIFI using opening

To photograph, camera shooting acquires picture；It, can be with 2. the APP software using mobile phone terminal handles the image data of acquisition
Obtain line branches direction, numbers of branches, plumber block hole count, cable item number, caliber size, buried depth, well room size, pipe trench width
Deng.Underground pipe well photogrammetric apparatus, 1. instrument hardware has mobile phone plane plate, the lens camera with WIFI, laser, light source, visits
Measuring staff is composed；2. carrying out WIFI connection to camera by mobile phone plane plate, carry out data transmission；3. by mobile phone plane plate to well
Lower data acquisition, controls picture shooting, judges pipe well type, line branches direction, plumber block hole count, branch by image or picture
Quantity, cable item number；4. borehole wall etc. carries out the resolving of picture using mobile phone terminal APP to pipeline to be measured, now laser is clicked through
Row coordinate obtains, then carries out coordinate respectively to target object both sides to be measured and obtain in the diameter and camera of last display measured object
Shooting distance of the heart to determinand.
