Description

Technical Field

[0001] The utility model relates to the technical field of three-dimensional terrain surveying and mapping, in particular to a three-dimensional terrain surveying and mapping auxiliary device. Background Art

[0002] Three-dimensional measurement, as the name implies, is to measure the object in all directions and determine the three-dimensional coordinate measurement data of the object. Its measurement principle is divided into four aspects: ranging, angular displacement, scanning, and orientation. Instruments developed based on the principle of three-dimensional technology include three types of measuring instruments: photographic (structured light) three-dimensional scanners, laser three-dimensional scanners, and three-coordinate measuring machines.

[0003] Based on the above, the inventors have found that the following problems exist: when the terrain of an area where three-dimensional topographic mapping is required is undulating, when using conventional surveying methods such as total stations or RTK for surveying, the total station bracket is very inconvenient to set up and level when used in areas with undulating terrain. When RTK is surveying, it is necessary to hold a measuring rod and move it continuously in the surveying area. Due to the undulating terrain, it is also very inconvenient for surveyors to walk. Therefore, drones are used for auxiliary surveying. However, existing drones require bolts when installing and disassembling three-dimensional laser scanners. The bolts always take a certain amount of time to install and disassemble, which has a certain impact on the measurement efficiency.

[0004] Therefore, in view of this, the existing structure and deficiencies are studied and improved, and a three-dimensional terrain surveying and mapping auxiliary device is provided, in order to achieve a more practical purpose. Utility Model Content

[0019] Furthermore, the input and output ends of the main controller are communicatively connected with the input and output ends of the three-dimensional laser scanner, the first servo motor, the anti-collision radar and the second servo motor.

[0035] Embodiment 3 of the utility model of a three-dimensional terrain surveying and mapping auxiliary device

[0036] Reference Figure 1 - Figure 5 As shown, a second servo motor 1004 is fixedly installed on one side of the upper end of the plurality of brackets 1002, and a blade 1005 is sleeved on the output end of the second servo motor 1004.

[0037] Specifically, the working principle of the three-dimensional terrain mapping auxiliary device is as follows: when in use, the mounting member 2001 is placed on the upper end surface of the three-dimensional laser scanner 2003, and the locking bolt 2009 is inserted into the U-shaped groove opened at the upper end of the mounting member 2002, and the bottom end thereof is aligned with a pair of threaded grooves opened at the upper end surface of the three-dimensional laser scanner 2003, and then the locking bolt 2009 is rotated to fix the mounting member 2002 on the upper end of the three-dimensional laser scanner 2003, and then the mounting frame 2002 is inserted into the slide groove 2011 opened on one side of the mounting box 2001, and the first servo motor 2005 is started through the main controller 1001 to drive the bidirectional lead screw 2006 to rotate, and the sliders 2007 arranged at both ends of the bidirectional lead screw 2006 are respectively slidably connected with the slide rod 2004, and then when the bidirectional lead screw 2006 rotates, the pair of sliders 2007 can be made to move relative to each other, and the sliders 2 An L-shaped plug 2010 is installed at the bottom end of 007. As the slider 2007 moves relative to each other, the bottom end of the L-shaped plug 2010 is inserted into the groove 2008 opened on both sides of the mounting piece 2002, fixing the mounting piece 2002 in the slide groove 2011. At this time, the second servo motor 1004 is started by the main controller 1001. When the second servo motor 1004 rotates, it can drive the blade 2005 to rotate, thereby causing the main controller 1001 and the three-dimensional laser scanner 2003 to rise, and then fly over the surveying area according to the established route to take pictures. After the surveying is completed, it is only necessary to control the first servo motor 2005 to start and drive the L-shaped plug 2010 to move toward the two ends to separate it from the groove 2008, so that the user can easily pull the mounting piece 2002 out of the slide groove 2011, which greatly saves the time for disassembling and assembling the three-dimensional laser scanner 2003.
