Description
Technical field
The utility model belongs to target coordinate measuring set technical field, and in particular to one kind is filled based on GNSS scanning surveys
It sets.
Background technology
GNSS (Global Navigation Satellite System, Global Navigation Satellite System) refers to all defend
Star navigation system, including it is the whole world, region and enhancing, such as the GPS in the U.S., the Glonass of Russia, Europe
Galileo, Chinese Beidou satellite navigation system, and relevant enhancing system.Global Navigation Satellite System (GNSS) to
GNSS receivers provide the ability that its position is determined based on the positioning signal transmitted from GNSS satellites.The position is according to warp
For degree, latitude and height, and it is accurate to several meters or even several centimetres.
GNSS receivers have become very for surveying, positioning, navigating, tracking, periodically with the civilian of many other purposes
Generally.Unfortunately, the property of GNSS signals and GNSS receivers be (at least in terms of civilian visual angle) they it is very weak and
Interference, deception (such as providing spurious signal or information to prevent to determine positioning), interference and other destroy is highly susceptible to (to dislike
Meaning or it is unintentional) etc. can damage easily reach GNSS receivers signal integrality or produced by GNSS receivers
The influence of the behavior of raw positioning output.In an increasingly crowded broadcast spectrum and increasingly brilliant and ambitious hacker's generation
In boundary, such damage of GNSS signal integrities is likely to increase.This may cause GNSS receivers that can not track to defend
Star, or the positioning that GNSS receivers may be caused to provide mistake in the case of deception or weak jamming export.
Global navigation satellite technology (GNSS) has many advantages, such as to lay convenient, at low cost, stable accuracy.Especially with
The maturation of GNSS precision positioning technologies (including RTK and PPP etc.), GNSS are able to gradually be applied to above-mentioned deformation monitoring neck
Domain.But there are measurement noises that big, dynamic accuracy declines, Yi Shougan for G N S S receivers
Disturb with the limitations such as real-time difference, therefore it is (practical when the structure monitored drastic mechanical deformation occurs or destroys
When being often most critical in), GNSS can not just be competent at.
When three dimension laser scanning surreying, scanning target need to be laid present, the later stage realizes that multistation scans according to public target
The splicing of data needs the data translocation of collection in worksite it is right to meet country into engineering coordinate system sometimes in practical engineering application
The management requirement of engineering survey coordinate system.
It at present when carrying out petroleum and petrochemical industry engineering scanning survey, need to carry out in two steps, lay scanning target first,
Target is scanned in scanning process；Later stage lays prism or GNSS receiver again in target placement, uses total powerstation
Or GNSS realizes the measurement of coordinate, with GNSS develop it is increasingly mature and universal, when in-site measurement mostly use greatly GNSS technologies into
Therefore row need to consider the device that a set of collection target point cloud acquisition and GNSS coordinate measure, and in location satellite poor signal or have
When the region blocked, ensure disposable realization above-mentioned requirements.
