Abstract
The invention discloses an auxiliary device for a scanner. The auxiliary device for the scanner comprises an anti-toppling device, a limiting device and a wheel unit. The scanner is arranged on the anti-toppling device, the anti-toppling device is arranged on the limiting device, and the limiting device is connected with the wheel unit. According to the auxiliary device, accuracy and efficiency are taken into consideration, and productivity is improved. Firstly, different from vehicle-mounted and onboard scanning systems, the auxiliary device has the advantage that the working mode of the scanner with the auxiliary device is not changed, so that scanning accuracy of the scanner stills maintains high accuracy of a ground type scanning system; secondly, due to the adoption of the operation procedure of shutdown-free station change, operation occupying too much time in the scanning process of the traditional ground type scanning system can be avoided, compared with the operation procedure of the traditional ground type scanning system, time is saved by 50%, and on the premise that scanning accuracy is kept unchanged, scanning work efficiency is improved and labor intensity of workers is relieved.
Description
Technical field
The present invention relates to a kind of three-dimensional laser scanner servicing unit, the special-purpose delivery of especially a kind of ground type three-dimensional laser scanner and stop means.
Background technology
The three-dimensional laser scanning technique outdoor scene reproduction technology that is otherwise known as is the technological revolution of survey field after GPS technology.It is different from traditional spot measurement method, has high-level efficiency, high-precision unique advantage.Adopt the three-dimensional laser scanning system of three-dimensional laser scanning technique that the three dimensional point cloud on scanning object surface can be provided, so can be for obtaining the digital terrain model of high-accuracy high-resolution.
By delivery vehicle and scanning accuracy, classify, the three-dimensional laser scanning system of present stage can be divided into ground type, vehicular and machine-carried type three classes.
Wherein, ground type scanning system is that scanner is fixed on to the enterprising line scanning of tripod, and the Result Precision of this scan mode is higher, more than generally can reaching 1mm.The operating process of traditional ground type scanning system is: select website, set up instrument, start leveling, scanning, shutdown, dismounting instrument, case, change website, so circulation.In above-mentioned flow process, time and manpower that " shutdown, dismounting instrument, vanning, change website, again set up instrument, start leveling " spends often surpass time and the manpower that " effective scanning " spends.The comparatively advanced Switzerland Lycra C10 pulsed scanner of take is in the market example, " shutdown, dismounting instrument, vanning, change website, again set up instrument, the start leveling " running time of carrying out because of " changing station " is generally 15-20 minutes, and general of actual " scanning " needed time is about 8-10 minutes." non-productive work " accounts for the more than 65% of amount of work, and work efficiency is lower, and because scanner deadweight is larger, being dismounted for multiple times equipment has also increased workman's labour intensity simultaneously.Therefore under many circumstances, when large-scale region is scanned, utilize traditional ground type scanning system often inconvenient and expend time in.
Vehicular scanning system can overcome an above-mentioned difficult problem, and reason is that vehicular scanning system is placed in scanner the roof of normal domestic use automobile, and scanner can scan in vehicle operating process, and the efficiency of scanning improves greatly.But its principle of work and data processing method are different from ground type scanning system completely, or can be described as two diverse scanning systems.The shortcoming of this vehicular scanning system is that scanning accuracy is low, and full accuracy also only has 5cm at present.With vehicular scanning system be similarly machine-carried type scanning system, it is applicable to wider scanning, sweep velocity is also faster, but scanning precision also lower, often lower than 0.5m.Except the difference of equipment itself, the key distinction of ground type scanning system and vehicle-mounted and airborne scanning system is the difference of navigator fix, what the former adopted is laser positioning, both often adopt GPS and inertial guidance afterwards, this be also after both scanning accuracy why lower than the former one of the main reasons.Therefore, how to collect the chief of various schools of thinkers, under the prerequisite that guarantees precision, improve scan efficiency and become engineering circles problem in the urgent need to address.
