NexVue™ Digital Camera Sales
The NexVue™ medium-format digital color camera offers an affordable
entry to aerial digital image acquisition while providing all the
benefits of direct digital capture over film-based procedures. As the
photogrammetric mapping industry continues its rapid move to all-digital
acquisition and production methods, NexVue™ can help companies meet
the increasing demands for true digital imagery.
NexVue™ has been designed and built as a true high-resolution aerial,
metric camera. The camera body,
lens mount, CCD mount and focal plane use a proprietary design and
exacting specifications resulting in the stable interior orientation
and repeatable calibration required for photogrammetric applications.
The compact size, combined with high spatial resolution and accuracy,
make NexVue™ ideal for use with LIDAR and other sensors such as
hyperspectral scanners, for simultaneous acquisition and data fusion of
multiple datasets through a single aircraft camera port.
Spectrum Mapping has extensive experience in system integration of a wide
array of airborne sensors, flight management systems and direct
geo-referencing systems. Users of NexVue™ will greatly benefit from
this experience and are fully supported through the entire process of
system design, installation and training for acquisition.
With over six years of successful use in the field, NexVue™ can
provide affordable digital image acquisition with entry level pricing and
low operational overhead. Flexible configuration options allow for
application-specific solutions and a well-defined upgrade path for future
enhancements.

Multiple Configurations
The NexVue™ digital color camera system is flexible and
scalable to meet all of your application needs. Depending upon your requirements, the
system can be configured in a wide variety of ways:
BASIC CONFIGURATION
- NexVue digital color 4k x 4k metric camera
- Digital camera operator console
- Data logger - camera interface and data storage
- Real-time image processing software
OPTIONS
- Flight Management System (FMS) - Spectrum offers the industry-leading XTRACK system by
Track’Air. XTRACK includes mission planning and photoflight management software with
raster backdrop and a yoke-mounted flat panel pilot display.
- GPS navigation along pre-planned flight lines
- Automatic camera trigger at exposure stations
- Ensures complete project coverage and consistent overlaps
- Inertial Navigation Systems (INS) - for direct georeferencing with optional integrated GPS/INS to achieve direct exterior orientation parameters for photogrammetric processing.
- Direct georeferencing with integrated GPS and IMU reduces ground control requirements
- Post-processing computes direct exterior orientation parameters
- Low-cost INS for projects with lower accuracy requirements
- High-end Applanix POS AV™ systems offer highest accuracy INS solutions to meet the most demanding mapping applications
- Stabilized Mount - compensates for roll, pitch and yaw of the aircraft.
- A variety of mounts can be modified for use with the NexVue™ camera
- Multiple Camera Configurations - One, two or more cameras can be combined
- Multispectral capability allows for simultaneous 4-band (RGB and CIR) acquisition from a single pass
- Expanded imagery swath width
Additional Benefits
- Broad Range of Applications: Includes photogrammetric mapping and digital orthophoto production, remote sensing and GIS analysis.
- Flexible Image Product Delivery: Interchangeable filters permit simple switch between collection of natural color (RGB) and Color IR. 24-bit TIFF image output for compatibility with all image analysis and photogrammetric processing systems.
- Interchangeable High Quality Lenses: Adapt the camera's field of view to match the swath width of other sensors (e.g. LIDAR) with either 90mm or 50mm lenses. Select maximum ground resolution for highest accuracy mapping or increase the width of coverage for greater efficiency of data capture.
- Large Storage Capacity: Approximately 3,000 color frames stored on a single disk set. Rapid in-flight exchange of storage media for almost unlimited capacity.
- Fast Turnaround on Projects: Immediate post-mission availability of digital imagery or even in-flight analysis for applications with time-critical response.
- Fast Frame Rate: Sub 2.5 second frame rate allows acquisition of stereo imagery, even at altitudes down to 1,000ft with fixed-wing platforms.
- 10-bit Dynamic Range: extract image information even in deep shadows and highly reflective regions within the same image. Imagery can be acquired under less than favorable light conditions, extending the number of flying hours.
- Real-Time Image Display: allows in-flight quality control of imagery.
- Constructed for Airborne Applications: small, ruggedized system for straightforward installation in single-engine aircraft or helicopter with small camera port size requirement.
- Ease of Operation: simple, clear operator interface displayed on integrated LCD screen. Real-time display of image data and histograms for review of exposure settings.
- Reduced Relief Displacement: minimal relief displacement resulting in less ground detail obscured by tall structures.
What is a Metric Camera?
The American Society for Photogrammetry and Remote Sensing (ASPRS) defines
a metric camera as – a camera whose interior orientation is known, stable
and reproducible. Most medium-format digital cameras that have been
adapted to aerial imaging do not deliver the highest accuracy for one
simple reason - the geometry of their interior orientation is not stable
or repeatable, i.e. they are not metric cameras. The result is that
such cameras must be re-calibrated on a much more frequent basis and
even then there is greater uncertainty in the geospatial accuracy of
any measurements or orthorectified images derived from the imagery.
The NexVue™ digital color camera now being offered by Spectrum Mapping
addresses this issue through its metric design, which includes a
dimensionally stable focal plane and lens mount. Geometric calibrations
on this camera are repeatable to within less than 0.5 pixels. At the
same time, the camera delivers exceptional radiometric quality, with
10-bit dynamic range and very low noise, and has a high frame cycle
rate of less than 2.5 seconds, permitting stereo imagery to be collected
even at relatively low altitudes. In addition to augmenting LIDAR data
collection, the camera can be deployed in stand-alone mode, in single or
dual-camera configurations, typically with GPS/INS for direct observation
of exterior orientation parameters, to acquire natural color and/or CIR
imagery for conventional mapping or remote sensing applications.
