Simple Calibration Techniques for Non-metric Cameras

چکیده
ABSTRACT Architectural documentation is carried out mostly with (analogue or digital) non-metric cameras or video-cameras. Unknown internal geometry is a main problem in this context, particularly for wide-angle lenses with their considerable amount of distortion. Self-calibrating bundle adjustment or 3D test-field calibration may provide straightforward answers to this problem, yet on occasions such steps can prove too complicated or costly for ordinary users. Hence, this paper discusses the use of simple pre-calibration approaches.

Calibraton of a Digital Single Lens Reflex (slr) Camera Using Artificial Neural Networks
The use of non-metric digital cameras in close-range photogrammetric applications and machine vision has become a popular research agenda. Being an essential component of photogrammetric evaluation, camera calibration is a crucial stage for non-metric cameras. Therefore, accurate camera calibration and orientation procedures have become prerequisites for the extraction of precise and reliable 3...
متن کاملExperiment on Precision of Camera Calibration of Non-metric Digital Cameras
Although many camera calibration methods for a non-metric digital camera have been proposed, there are few reports on the precision of calibration results. Therefore, we conducted a field experiment in order to examine the precision of calibration results of a non-metric digital camera. We adopted a calibration method using a set of calibration points distributed on the 2-D plane with no ground...
متن کاملNew approach for calibration of pixelated scintillation detectors of intraoperative gamma cameras
Introduction:SURGEOSIGHT is a dedicated intra-operative hand-held gamma camera designed and manufactured by our team to be used for lymphoscintigraphy. Although conventional gamma cameras are widely used, they lack the capability of the sentinel lymph node (SLN) imaging in the operation room. Like conventional gamma cameras it is necessary to calibrate SURGEOSIGHT for linearity...
متن کاملCalibration of uncooled thermal infrared cameras
The calibration of uncooled thermal infrared (IR) cameras to absolute temperature measurement is a time-consuming, complicated process that significantly influences the cost of an IR camera. Temperaturemeasuring IR cameras display a temperature value for each pixel in the thermal image. Calibration is used to calculate a temperature-proportional output signal (IR or thermal image) from the meas...
متن کاملCalibration of Pan-Tilt-Zoom (PTZ) Cameras and Omni-Directional Cameras
In the first part we discuss the problem of recovering the calibration of a network of pan-tilt-zoom cameras. The intrinsic parameters of each camera over its full range of zoom settings are estimated through a two step procedure. We first determine the intrinsic parameters at the camera’s lowest zoom setting very accurately by capturing an extended panorama. The camera intrinsics are then dete...
