Description
Technical field
The utility model relates to a kind of coupling arrangement of Three Dimensional Ground laser scanner
Technical background
three-dimensional laser scanning technique is widely used in engineering mapping, the fields such as structure measurement and building detection, the three-dimensional laser scanning technique development reached its maturity in recent years, 3-D scanning equipment is commercialization gradually also, the huge advantage of Three Dimensional Ground laser scanner is exactly can the rapid scanning testee, do not need reflecting prism can directly obtain high-precision scanning cloud data, but the characteristics due to three-dimensional laser scanning technique itself, obtain the complete cloud data of measurand, need to carry out many viewpoint scannings, then multi-viewpoint cloud data is registrated in the same coordinate system, consist of a complete some cloud object.Traditional multi-viewpoint cloud method for registering is to use algorithm or use characteristic target to carry out registration, uses the algorithm registration need to obtain the initial attitude of different survey station cloud datas, and calculated amount is large, efficient is low; The use characteristic target carries out registration to be needed at the feature target of the public domain of different survey stations laying more than 3 or 3, to realize the registration of different survey station cloud datas, the method is subjected to the restriction in place larger, and easily causes the propagation of error, causes the some cloud precision after registration low.
Summary of the invention
The purpose of the present utility model is to overcome the deficiencies in the prior art, is connected with the Three Dimensional Ground laser scanner by the scanner positioning pedestal, can directly position the ground three-dimensional laser scanner, obtains the coordinate of its true origin under target-based coordinate system.
Concrete technical scheme of the present utility model is as follows:
A kind of Three Dimensional Ground laser scanner positioning pedestal, comprise that axis check point, positioning pedestal pier, scanner can revolve that pilum, scanner can revolve the pilum groove, three-jaw can revolve chassis, left arm measuring point and right arm measuring point, the positioning pedestal pier is provided with scanner can revolve the pilum groove, scanner can revolve pilum in scanner can revolve the pilum groove, three-jaw can revolve the below that the chassis is positioned at the positioning pedestal pier, on the test arm of left and right, reflector plate is installed, the reflector plate center is point position, and scanner can revolve pilum and be connected with the Three Dimensional Ground laser scanner; Such scheme is done further restriction, and the positioning pedestal pier is provided with the horizontal tube bubble; Such scheme is done further restriction, and it is adjustable that three-jaw can revolve the position, chassis, with locking screw; Such scheme is done further restriction, and scanner can revolve pilum and be provided with the safety locking spiral; Such scheme is done further restriction, expansion interface before and after the positioning pedestal pier is provided with.
The utlity model has following beneficial effect:
1. data acquisition efficiency is high, can directly obtain the cloud data under target-based coordinate system;
2. applied range, can use in the place that can't lay the feature target;
3. error propagation is little, and data precision is high;
