【摘要】：由于測(cè)距原理不同,相位式地面三維激光掃描儀相較于脈沖式具有測(cè)量精度高、測(cè)程短的特點(diǎn)。文中以Z+F IMAGER 5010C相位式地面三維激光掃描儀為試驗(yàn)對(duì)象,從距離入手,對(duì)其內(nèi)、外符合精度進(jìn)行了計(jì)算分析,并研究了此掃描儀用于變形監(jiān)測(cè)的適用條件。結(jié)果表明:Z+F IMAGER 5010C掃描儀的測(cè)量精度隨著距離的增加而降低;內(nèi)符合精度要優(yōu)于外符合精度;內(nèi)符合精度分析結(jié)果表明,在設(shè)置靶標(biāo)用于掃描數(shù)據(jù)配準(zhǔn)的作業(yè)方式下同時(shí)開展高程、水平方向的監(jiān)測(cè),掃描儀距離掃描對(duì)象控制在30 m之內(nèi),可進(jìn)行三級(jí)變形監(jiān)測(cè);外符合精度分析結(jié)果表明,借助全站儀測(cè)量靶標(biāo)中心點(diǎn)坐標(biāo)用于掃描數(shù)據(jù)配準(zhǔn)的作業(yè)方式下同時(shí)開展高程、水平方向的監(jiān)測(cè),掃描儀距離掃描對(duì)象的距離控制在20 m之內(nèi),亦可進(jìn)行三級(jí)變形監(jiān)測(cè)。
[Abstract]:Because of the different ranging principles, the phase 3D laser scanner has the characteristics of high accuracy and short range compared with the pulse laser scanner. Taking the Z F IMAGER 5010C phase 3D laser scanner as the experimental object, the accuracy of the internal and external coincidence is calculated and analyzed from the distance, and the applicable conditions of the scanner for deformation monitoring are studied. The results show that the measuring accuracy of the Z F IMAGER 5010C scanner decreases with the increase of distance, the accuracy of internal coincidence is better than that of external coincidence, and the analysis results of the accuracy of internal coincidence show that, In the operation mode of setting target for scanning data registration, the monitoring of elevation and horizontal direction is carried out simultaneously. The scanner is controlled within 30 m from the scanning object and can be monitored for three stages of deformation. The result of precision analysis of external coincidence shows that, With the aid of total station measuring the coordinate of the center point of the target, the height and horizontal direction are monitored simultaneously in the operation mode of scanning data registration. The distance between the scanner and the scanned object is controlled within 20 m, and the third level deformation monitoring can also be carried out.
