TOWARDS ROBUST SELF-CALIBRATION FOR HANDHELD 3D LINE LASER SCANNING
structured light self-calibration laser scanning 3D reconstruction
2018/3/5
This paper studies self-calibration of a structured light system, which reconstructs 3D information using video from a static consumer camera and a handheld cross line laser projector. Intersections b...
ATMOSPHERIC CORRECTION,REFLECTANCE CALIBRATION AND BRDF CORRECTION FOR ADS40 IMAGE DATA
Multispectral Modelling Aerial Calibration Land Use Mapping Atmosphere Radiometry Correction
2015/12/30
A new radiometric workflow for ADS40 line scanner data has been developed and implemented. It includes now two additional atmospheric correction algorithms and an empirical BRDF correction. Both atmos...
Zoom-dependent calibration for consumer grade-cameras
self calibration camera calibration lens distortion zoom lens
2015/8/24
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 sett...
Satellite cameras are calibrated in laboratory before launch, but the geometry may change by the strong acceleration of the
launch and by thermal influence of the sun. CCD-line scan cameras have to ...
CALIBRATION OF CURVATURE OF FIELD FOR DEPTH FROM FOCUS
Metrology Calibration Depth from Focus
2015/5/18
A method for accurate depth measurement in depth from focus is presented. With depth from focus the 3D shape of objects can be
measured. To do so, an image series with different distances between cam...
NUMERICAL SIMULATION ON EVALUATING CALIBRATION RESULTS OF NON-METRIC DIGITAL CAMERA
Digital Calibration Orientation Simulation
2015/5/18
A non-metric digital camera is required to be geometrically calibrated when it is used for photogrammetric applications. Many
camera calibration methods for a non-metric digital camera have been pro...
ORIENTATION AND AUTO-CALIBRATION OF IMAGE TRIPLETS AND SEQUENCES
Auto Calibration Orientation Robust Trifocal Tensor
2015/5/18
The automatic orientation and auto-calibration of image triplets and sequences is the basis for applications in visualization but also for
all tasks employing metric information from imagery. Here we...
Recent increase in number of pixels of images acquired by a non-metric digital camera encourages an amateur to utilize it for 3D
measurement. Most of current camera calibration methods are inconveni...
LABORTARY SELF-CALIBRATION OF A MULTI-BAND SENSOR
Camera Calibration CAMIS Self-Calibration
2015/3/24
CAMIS is a multi-band airborne remote sensing instrument and is designed to utilize modern solid-state imaging and data
acquisition technology. It is composed of four CCD cameras with band pass opti...
Within the last years extensive tests were done to investigate the accuracy performance of integrated GPS/inertial systems for direct
georeferencing in airborne photogrammetric environments. Based o...
CYLINDER-BASED SELF-CALIBRATION OF A PANORAMIC TERRESTRIAL LASER SCANNER
TLS Geometric Calibration Close Range Feature Object Accuracy
2014/4/28
Terrestrial Laser Scanners (TLSs) have become state-of-the-art metrological sensors for many surveying purposes in recent years. Due to the demand for high precision surveying with TLSs, efficient, ri...
