Calibration of a Mobile Mapping Camera System with Photogrammetric Methods
The road network is an essential economic factor for the German industry. Until now, the whole horizontal and vertical alignment parameters are not known. To determine these parameters the Technische Universität Dresden has implemented a measurement system which is realised in a mobile mapping vehicle. The car includes the following sensors: Position and orientation system Applanix POS LV 420, ...
متن کاملThe Development of Camera Calibration Methods and Models
Correction for image distortion in cameras has been an important topic for as long as users have wanted to faithfully reproduce or use observed information. Initially the main application was mapping. While this task continues today other applications also require precise calibration of cameras such as close range 3-D measurement and many 2-D measurement tasks. In the past the cameras used were...
متن کاملDigital Camera Calibration Methods: Considerations and Comparisons
Camera calibration has always been an essential component of photogrammetric measurement, with self-calibration nowadays being an integral and routinely applied operation within photogrammetric triangulation, especially in high-accuracy close-range measurement. With the very rapid growth in adoption of off-the-shelf digital cameras for a host of new 3D measurement applications, however, there a...
متن کاملCamera Calibration with Distortion Models and Accuracy Evaluation
The objective of stereo camera calibration is to estimate the internal and external parameters of each camera. Using these parameters, the 3-D position of a point in the scene, which is identified and matched in two stereo images, can be determined by the method of triangulation. In this paper, we present a camera model that accounts for major sources of camera distortion, namely, radial, decen...
متن کاملNovel Patterns and Methods for Zooming Camera Calibration
Camera calibration is a necessary step in order to develop applications that need to establish a relationship between image pixels and real world points. The goal of camera calibration is to estimate the extrinsic and intrinsic camera parameters. Usually, for non-zooming cameras, the calibration is carried out by using a grid pattern of known dimensions (e.g., a chessboard). However, for camera...
