Oblique Image Collection -- Challenges and Solutions
نویسندگان
چکیده
For over a decade now oblique images are collected from airborne platforms on a regular basis. Several camera products have been presented from distinct camera vendors and their image products are well known. The UltraCam Osprey is the new oblique sensor by Microsoft / UltraCam Business Unit and was introduced into the market at the ASPRS 2013. This camera combines a metric nadir subsystem creates one panchromatic high resolution image, one true-color RGB image, one near-infrared image and six oblique true-color wing images taken at an off-nadir angle of 45°. This specific camera design supports exceptional productivity and quality during acquisition and processing. Camera specification parameters as well as results from aero-triangulation, DSM production, and oblique image processing are presented in this article.

متن کاملModeling Façade Structures Using Point Clouds From Dense Image Matching
The automated generation of 3D computer models for urban planning and disaster management is an ongoing activity since about two decades. For 10-15 years aerial LiDAR seemed to be a key technology to solve the data collection problem for this purpose. Today, aerial photographs with nadir and oblique viewing directions overcome many obstacles and can be processed by dense image matching algorith...
