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
One, technical field
The invention belongs to the methods of pipe well measurement in City Buried Pipeline investigation.
Two, technical background
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.
Three, 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, detection bar are composed；2. carrying out WIFI connection to camera by mobile phone plane plate, carry out data transmission；3. flat by mobile phone
Plate acquires downhole data, controls picture shooting；4. using mobile phone terminal APP to pipeline to be measured, borehole wall etc. carries out picture
Resolve, now to laser point carry out coordinate acquisition, then to target object both sides to be measured carry out respectively coordinate obtain finally show to
Shooting distance of the diameter and image center of survey object to determinand.
Four, 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.
Five, specific embodiment:
