Calibration Method For Texel Images Created From Fused Lidar And Digital Camera Images, Scott E. Budge, N.S. Badamikar
Calibration Method For Texel Images Created From Fused Lidar And Digital Camera Images, Scott E. Budge, N.S. Badamikar
Electrical and Computer Engineering Faculty Publications
The fusion of imaging lidar information and digital imagery results in 2.5-dimensional surfaces covered with texture information, called texel images. These data sets, when taken from different viewpoints, can be combined to create three-dimensional (3-D) images of buildings, vehicles, or other objects. This paper presents a procedure for calibration, error correction, and fusing of flash lidar and digital camera information from a single sensor configuration to create accurate texel images. A brief description of a prototype sensor is given, along with a calibration technique used with the sensor, which is applicable to other flash lidar/digital image sensor systems. The method …
Automatic Registration Of Multiple Texel Images (Fused Lidar/Digital Imagery) For 3d Image Creation, Scott E. Budge, N. Badamikar
Automatic Registration Of Multiple Texel Images (Fused Lidar/Digital Imagery) For 3d Image Creation, Scott E. Budge, N. Badamikar
Electrical and Computer Engineering Faculty Publications
Creation of 3D images through remote sensing is a topic of interest in many applications such as terrain / building modeling and automatic target recognition (ATR). Several photogrammetry-based methods have been proposed that derive 3D information from digital images from different perspectives, and lidar- based methods have been proposed that merge lidar point clouds and texture the merged point clouds with digital imagery. Image registra tion alone has difficulty with smooth regions with low contrast, whereas point cloud merging alone has difficulty with outliers and lack of proper convergence in the merging process. This paper presents a method to create …
A Calibration-And-Error Correction Method For Improved Texel (Fused Ladar/Digital Camera) Images, Scott E. Budge
A Calibration-And-Error Correction Method For Improved Texel (Fused Ladar/Digital Camera) Images, Scott E. Budge
Electrical and Computer Engineering Faculty Publications
The fusion of imaging ladar information and digital imagery results in 2.5-D surfaces covered with texture information. Called "texel images," these datasets, when taken from dierent viewpoints, can be combined to create 3-D images of buildings, vehicles, or other objects. These 3-D images can then be further processed for automatic target recognition, or viewed in a 3-D viewer for tactical planning purposes. This paper presents a procedure for calibration, error correction, and fusing of ladar and digital camera information from a single hand-held sensor to create accurate texel images. A brief description of a prototype sensor is given, along with …
