| Abstract | ||||
| Terrestrial laser scanners provide high spatial resolution and accuracy three-dimensional (3D) data where data collection does not necessitate physical contact with the object if interest. For these reasons, point-cloud coordinate information acquired is widely utilized in a variety of surveying and civil engineering applications in addition to many applications in the close-range domain. Several publications have investigated the quality of the data, to ensure the achievement of high accuracy and examine the several factors influencing it, as one important feature of TLS-based object acquisition and modelling is data quality, which is used to determine the compatibility for a specific application. Some publications on the data quality of TLS and mainly concerning geometric accuracy, reflectivity of standard targets or the influence of different realistic object materials and object colors on TLS range measurements and recorded intensity values. Another aspect was investigated in this paper regarding the effect of two distinct materials with different colors on taking actual linear measurements from the acquired point cloud data. Measurements were taken on different distance intervals and results show that different scanning materials of various colors produce point clouds of varying quality. | ||||
