The UltraCam D Large Format Digital Aerial Camera
Features
No film, no photo lab, no scanning—the UltraCam is an investment that pays for itself
No noise from film grain
No cost for color nor for color-IR
Better radiometry for more flying days, more success in automated processes, and better stereo imagery
The miracle of no-cost, high forward overlaps optimizes the number of photos per project for accuracy, automation, and robustness UltraCam “Plug-and-play” compatibility maintains traditional workflow yet delivers increased productivity Shortened delivery times to customers
The only digital solution to single-handedly replace your film camera for all mapping
Overview
VEXCEL‘S REVOLUTIONARY ULTRACAM
digital camera system delivers large format aerial imagery that is radiometrically and geometrically superior to images captured by conventional film cameras at a comparable price.
The technological approach used in developing the UltraCam is clever, yet surprisingly simple. The camera
supports a high degree of parallelism in data collection, transfer and processing, and therefore reduces cost and sensitivity to environmental effects. Yet it enforces a single coordinate system, a single perspective center, and produces a highly accurate digital image.
The UltraCam features a better than 12-bit per pixel dynamic range, compared to film cameras at less than 8-bits per pixel, and without any grain-noise. The result is unrivaled radiometry with better matching accuracy, allowing for more flying days in marginal weather as well as better interpretability, better stereo, and more success in automated procedures.
The UltraCam digital process makes it completely compatible with existing photogrammetric procedures,
while increasing productivity. More importantly, the images from the UltraCam-D feed into existing photogrammetric work flows and vastly improve automation, using no-cost redundancy.
UltraCam Configuration
Sensor Unit (SU)
Distributed parallel sensing achieved with a set of 8 optical cones to assemble a large format digital image in color 13 area array CCDs collect pixels
Each CCD array feeds signals into its own compact and proprietary electronics setup and data path The “Master Cone” provides single image coordinate system
Storage and Computing Unit (SCU)
Each CCD array accompanied by separate “private” processing and storage components, with capacity for dual redundant storage 15 units are assembled into removable cabinet,
providing distributed parallel storage and computing
Rich Data Flow Options
On-board system with SU and SCU is all that is needed for image acquisition, preprocessing and delivery Images are collected and pre-process is started during flight for creation of deliverable output images SCU is a multi-processor computer with 15 CPUs On the ground, pre-processing can optionally be completed onboard the idle plane, in a
mission office, or in the home office Transfer data from the SCU using Mobile Storage unit (MSU)—a set of external disks in a small portable “briefcase” ready for shipment
