Canon EOS 5D Mark II DSLR Camera
The Canon EOS 5D Mark II DSLR Camera has been used for the creation of 3D models using close-range photogrammetry, documentation and Reflective Transformation Imaging (RTI) processes.
The Epson 10000XL is a large format scanner designed to scan photographic prints or negatives up to 12.2″ x 16.5″ at a resolution of 2400 dpi and bit depth of 16 bits.
The Nikon D200 (originally introduced in 2005) is a digital SLR camera with 10.2 million pixels over a DX format sensor (23.6 x 15.8 mm) and is well suited for close-range digital photogrammetric projects. A range of fixed focus and zoom lenses are available for use with this camera, making it flexible enough for a range of project needs.
Nikon D200 IR3
The Nikon D200 (originally introduced in 2005) is a digital SLR camera with 10.2 million pixels over a DX format sensor (23.6 x 15.8mm). This particular camera has been modified so that visible light is blocked and infrared light is transmitted. This was done by removing the OEM internal “hot mirror filter” and replacing it with a filter designed to block all wavelengths <720 nanometers. This filter is the equivalent to the Hoya R72 or Kodak Wratten 89b glass lens filters. A custom focus calibration was also done to adjust the auto focus for IR light. This calibration was done specifically for the AF Nikkor 28 mm fixed focus lens.
The IR filter installed is considered to be a 720 nm filter because at 50% transmission, any wavelength below 720 nm is blocked. However, some red light (wavelengths between ~680 and 750 nm) is partially transmitted by the IR filter and captured by pixels with a red Bayer filter (25% of the sensor). This means the typical R, G, B channels deliver digital counts equal respectively to Partial Red+IR, IR Only, IR Only.
The Nikon D70 (originally introduced in 2004) is a digital SLR camera with 6.1 million pixels over a DX format sensor DSLR camera that is well suited for close-range digital photogrammetric projects. A range of fixed focus and zoom lenses are available for use with this camera, making it flexible enough for a range of project needs.
Raytheon Palm IR250 Thermal Imager
The Raytheon Palm IR250 Thermal Imager is a single band hand-held scanner. All natural and man-made objects emit infrared energy; the hotter they are the more infrared energy they emit. Thermal imaging provides the ability to see and record temperature differences. Infrared shares many of the properties of visible light, but its different wavelength has several unique characteristics. For instance, materials that are opaque to visible light may be transparent to infrared and vice versa. Infrared is less subject to scattering and absorption by smoke or dust than visible light and infrared cannot be seen by the human eye. Unlike visible light, which is given off by ordinary objects only at very high temperatures, infrared is emitted by all objects at ordinary temperatures.
