چکیده

This paper describes direct interactive relative orientation method between terrestrial digital images and laser scanner data. Traditionally, the orientation between images and 3D data requires interactive work and accurate reference points or visible features. Laser scanning data does not easily allow detection of breaklines or corner points. Due to the huge amount of data, however, it is possible with human intelligence and interactive orientation method to perceive the entity and to register terrestrial images and laser data to each other. The paper describes the basic tools for interactive orientation and contains discussion about the applicability of the method. An example from a test site is depicted in order to demonstrate interactive orientation in a practical situation.

Orientation of Airborne Laser Scanning Point Clouds with Multi-View, Multi-Scale Image Blocks

Comprehensive 3D modeling of our environment requires integration of terrestrial and airborne data, which is collected, preferably, using laser scanning and photogrammetric methods. However, integration of these multi-source data requires accurate relative orientations. In this article, two methods for solving relative orientation problems are presented. The first method includes registration b...

Orientation and integration of images and image blocks with laser scanning data

Laser scanning and photogrammetry are methods for effective and accurate measurement and classification of urban and forest areas. Because these methods complement each other, then integration or integrated use brings additional benefits to real-life applications. However, finding tie features between data sets is a challenging task since laser scanning and imagery are far from each other in na...

Integration of a Terrestrial Laser Scanner with Gps/imu Orientation Sensors

Direct orientation of laser systems has been widely used for airborne laser sensors but not with the terrestrial laser systems. The usual way to operate a terrestrial laser is by scanning a scene while the sensor remains static. In order to cover the whole scene, different scans can be combined by matching several common points, finally the orientation of the scene is performed by identifying a...

Laser Data for Virtual Landscape Generation

Within this article a procedure for the automatic generation of 3D city models is presented. For that purpose existing ground plans provided from a 2D GIS and height data measured by airborne laser scanning are combined. The presented approach can be applied for a fully automatic reconstruction of an urban model, for interactive control and correction of these automatically generated results an...

Semi-Automatic Registration of Airborne and Terrestrial Laser Scanning Data Using Building Corner Matching with Boundaries as Reliability Check

Data registration is a prerequisite for the integration of multi-platform laser scanning in various applications. A new approach is proposed for the semi-automatic registration of airborne and terrestrial laser scanning data with buildings without eaves. Firstly, an automatic calculation procedure for thresholds in density of projected points (DoPP) method is introduced to extract boundary segm...
