Automatic Camera Calibration in Close-range Photogrammetry
Automatic camera calibration via self-calibration with the aid of coded targets is now very much the norm in closerange photogrammetry. This is irrespective of whether the cameras to be calibrated are high-end metric, or the digital SLRs and consumer-grade models that are increasingly being employed for image-based 3D measurement. Automation has greatly simplified the calibration task, but ther...
متن کاملA New Camera Calibration Method Based on Orientation Points in Digital Close-Range Industrial Photogrammetry
In order to solve the restriction of the two common calibration modes applied in digital close-range industrial photogrammetry, a new camera calibration method based on orientation points was proposed. Firstly, image sequences were obtained applying a calibration plate with five orientation points. The ellipse detection criteria were applied to eliminate the redundant information from images af...
متن کاملAccident Reconstruction via Digital Close-range Photogrammetry
With the ever wider adoption of spatial information analysis, there has been an increasing awareness of the importance of 3D data acquisition systems to support traffic accident reconstruction and forensic analysis. In an application such as accident reconstruction, GIS and CAD systems have limited utility without the underlying data. Digital close-range photogrammetry displays many attributes ...
متن کاملDigital Close-range Photogrammetry Using Artificial Targets
A procedure for an automatic search and measurement of artificial targets in digital images for elose-range photogrammetric applications is presented. Photographs taken with a sem i metric 6x6 camera were digitized by the "ASTROSCAN" at the Sterrewacht Leiden. The especially designed targets contain a circular barcode for automatic identification. It is shown that this procedure improves both p...
متن کاملZoom-dependent Calibration for Consumer Grade-cameras
A significant practical constraint currently applying to the adoption of consumer-grade digital cameras for photogrammetric measurement is the requirement to record images at fixed zoom and focus settings. This is a consequence of the variation of camera calibration parameters, especially principal distance and lens distortion, with changing zoom and focus. This paper describes a zoomdependent ...
