In, because the track that various factors causes to build deviates default track routes, it is therefore desirable to the track built is carried out real-time
Measurement, it is ensured that the safe operation of track.
Traditional track is the detecting system based on total powerstation and track detection car, this e measurement technology detection essence
Degree is higher, provides important technical support for the track accurate adjustment of China Express Railway primary construction.It is but this using complete
Computer of the data transfer to operational terminal of instrument of standing measurement, also need to be further processed after computer receiving data, increase
The workload of staff, while the data fed back are also not directly perceived enough.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of track close shot laser scanner and method, structure
Simply, staff to measurement data without being for further processing, data feedback quicklook, and measurement is accurate, or work
Journey project construction and operation management safeguard that the foundation of BIM models provides initial data.
The technical scheme that the present invention solves above-mentioned technical problem is as follows：
A kind of track close shot laser scanner and method, including positioning target, laser scanner, running trolley with
And server, the positioning target have multiple and are correspondingly arranged on the CPIII marks of track both sides, the laser scanner peace
On the running trolley, the running trolley sets in orbit simultaneously track-movable, and the laser scanner is to both sides
The track and positioning target, which are scanned, takes pictures and gathers cloud data and picture, the laser scanner and the server
Connected by wireless signal.
The beneficial effects of the invention are as follows：Laser scanner is as the propulsion of running trolley is to the track and positioning target of both sides
It is scanned and takes pictures and gather cloud data and picture, and the particular location of track, the data of feedback is determined by positioning target
Compare directly perceived, it is not necessary to which staff is for further processing, and measuring speed is fast, and precision is high.
On the basis of above-mentioned technical proposal, the present invention can also do following improvement.
Further, column has been removed and installed on the running trolley, the laser scanner is arranged on the column.
Further, the laser scanner is using laser scanner.
Beneficial effect using above-mentioned further scheme is only to need a laser scanner.
Track and positioning target to running trolley both sides, which are scanned, takes pictures and gathers cloud data and picture, structure letter
Single, the cloud data and picture collected is more comprehensive, measures fast accurate.
Further, the CPIII marks are evenly distributed on track both sides, and metallic sheath is correspondingly provided with the CPIII marks
Cylinder.
Beneficial effect using above-mentioned further scheme is that positioning target is arranged on metal sleeve, install convenient, simultaneously
It is easy to laser scanner to be scanned positioning target and gathers cloud data and picture.
Further, the positioning target is provided with the coordinate for determining track particular location, and the positioning target bottom is provided with
Magnet, the positioning target are detachably connected by the magnet and the metal sleeve.
Beneficial effect using above-mentioned further scheme is that positioning target is connected by magnet with metal sleeve, dismounting letter
Just, while laser scanner by the coordinate on Scan orientation target and gathers cloud data and picture, it may be determined that track
Particular location, rapidly and efficiently.
A kind of track close shot laser scanning measurement method, using above-mentioned measurement apparatus, comprises the following steps：
(1) running trolley is placed in orbit, the column, the laser scanner and the positioning target is installed
Mark；
(2) running trolley is started, the laser scanner is scanned to the track of both sides and the positioning target
And gather cloud data and picture；
(3) cloud data collected and picture are passed to the server by the laser scanner.
Brief description of the drawings
Fig. 1 is the measurement structural representation of the present invention；
Fig. 2 is the structural representation of running trolley of the present invention, column and laser scanner installation.
In accompanying drawing, the list of parts representated by each label is as follows：
1st, laser scanner, 2, running trolley, 3, positioning target, 4, column, 5, metal sleeve.
Embodiment
The principle and feature of the present invention are described below in conjunction with drawings and the specific embodiments, example is served only for solving
The present invention is released, is not intended to limit the scope of the present invention.
As depicted in figs. 1 and 2, a kind of track close shot laser scanner of present invention offer, including positioning target 3,
Laser scanner 1, running trolley 2 and server, positioning target 3 has multiple and correspondingly the CPIII installed in track both sides is marked
In will, CPIII marks are evenly distributed on track both sides, are correspondingly provided with metal sleeve 5 on CPIII marks, positioning target 3 is provided with
Determine that the bottom of coordinate setting target 3 of track particular location is provided with magnet, positioning target 3 is removable by magnet and metal sleeve 5
Unload connection.Column 4 is detachably installed, laser scanner 1 is using 360 ° of panorama laser scanners and peace on running trolley 2
On column 4, running trolley 2 sets in orbit simultaneously track-movable, as running trolley 2 is constantly pushed ahead, laser
