Description
Technical field
The utility model relates to a kind of connecting link, relates in particular to the supporting connecting link of a kind of laser scanning measurement.
Background technology
In the laser scanning measurement operation; Often need to use three-dimensional laser scanner; Three-dimensional laser scanner is the quick measuring system of robotization of no cooperative target laser range finder and angle measurement system combination, can carry out quick scanning survey to testee in the scene and the space of complicacy, horizontal direction, zenith distance, oblique distance and the reflection strength of the body surface that directly obtains laser point and contacted; And store automatically and calculate, to obtain the cloud data of testee.Cloud data is through after the Computer Processing, but goes out the various cartographic datas such as three-dimensional model and line, face, body, space of testee in conjunction with the CAD quick reconfiguration.More than 1,000 meter of the measuring distance farthest of three-dimensional laser scanner; The maximum scan frequency can reach the per second hundreds of thousands; Longitudinal scanning angle θ is near 90 °; Laterally can carry out 360 ° of wholecircle scannings around the instrument vertical pivot, scan-data can be transferred to computing machine automatically through ICP/IP protocol, and the scene image of its external digital camera shooting can be transferred in the computer through the usb data line simultaneously simultaneously.But, need after the completion to be scanned the cloud data of the testee that obtains is spliced because the complicacy of testee or testee environment of living in when testee is carried out laser scanning, need be provided with several different websites sometimes testee is scanned.
In existing laser scanner technique operation process; For accomplishing the splicing of cloud data; Reflection paster or foot rest reflector plate need be set as reflecting body on the testee surface, carry out data splicing as the same place data of the cloud data of different websites with the scan-data of paster or reflector plate.When paster or reflector plate during over against the laser scanner direction, the paster of reflecting body or the reflected energy of reflector plate are the highest, and reflecting effect is best, and laser scanner can access reflecting body data more clearly, thereby the splicing precision of testee data is higher; If but the laser-bounce direction of the direction of scanning of laser scanner and paster or reflector plate forms angle; Then reflecting effect weakens; The cloud data shape of reflecting body can produce distortion, and angle is big more, and reflecting effect is poor more; Be out of shape big more, thereby the error that produces when causing splicing the cloud data of different websites is big more.Thereby those skilled in the art has developed a kind of standard ball as reflecting body, and this reflection sphere that is used to launch laser is a standard ball, and reflection direction and laser scanning direction do not have angle, can not produce distortion during reflector laser, helps improving the splicing precision.If but reflection sphere directly is installed on the foot rest, because the space on the foot rest is less, can causes certain difficulty to installation, and also be unfavorable for obtaining the scan-data of reflection sphere clearly.
Simultaneously, though, do not check condition, therefore need to guarantee to have the certain figure condition of reflection sphere data formation of three same places to splice because single reflection sphere can be avoided itself being out of shape the influence that produces.And when three reflection spheres were installed on the foot rest, the relative distance between three reflection spheres was too short, does not reach desirable graphical effect.
Therefore, those skilled in the art is devoted to develop a kind of supporting connecting link of laser scanning measurement that reflection sphere can be installed and have certain length.
