Advanced design
The Z/I DMC II250 is based on the DMC II camera family design. It includes five nadir-looking camera heads four multispectral Z/I is a world leader in providing photogrammetric solutions that cameras for red, green, blue, (RGB) and near-infrared (NIR), and a fifth support all your earth imaging requirements, from data acquisition high-resolution PAN camera head. Each multispectral camera has a to exploitation and data distribution. Our Digital Mapping Camera 42 MPixel CCD (6846 x 6096 pixel) with 7.2 micron pixel size and a (DMC ) is the industrys most innovative turnkey large-format digital dedicated color filter. The focal length for the multispectral cameras is camera system. We developed the medium-format Z/I RMK D so 45 millimeters (mm). Each camera head uses a unique piezo-driven more organizations can take advantage of the most advanced imaging customized airborne shutter that performs automatic self-calibration. technology available. Now, Z/I offers the Z/I DMC II250, the first largeThis also ensures maximum synchronous behavior during the expoformat digital aerial camera that uses a single monolithic camera sure cycle for all five camera heads. The PAN camera includes a 250 (figure 1) head to produce extreme wide-ground coverage (figure 2). MPixel CCD with 5.6 micron pixel size and 112 mm focal length. The PAN camera has an infrared cut-off filter to remove the spectral wave length beyond 710 nm.
The Z/I DMC II250 includes one large 17.2k x 14.6k charge-coupled device (CCD), exclusively customized by DALSA for Z/I Imagings digital camera technology. The Z/I DMC II250 camera design is an evolution of the proven DMC camera technology and includes a new customized lens design by Carl Zeiss, Germany, to produce an unmatched level of high-image quality.The single monolithic PAN camera head achieves the ultimate design goal for digital aerial camera development with one single lens for large ground coverage, the basic optics design principle for all film cameras for many decades. By eliminating potential sources of errors for geometric accuracy and radiometric quality, this new approach delivers images that exceed your requirements for all mapping and remote sensing tasks. Fundamental design characteristics include a nadir-looking view and a single-lens projection center. The Z/I DMC II250 image data post-processing does not require CCD stitching or image mosaicking.
Increased performance
Our Z/I DMC II250 is a high-performance digital camera system. It has a high frame rate to maintain fast-air speed for high-forward overlap and high resolution (at 80 percent forward overlap and 10 centimeter [cm] Ground Sample Distance [GSD], maximum air speed is 237 knots). The PAN/color ratio of 1:3.2 provides high-radiometric quality images for RGB and Color-InfraRed (CIR). The long focal length and small pixel size delivers high-resolution image data 10 cm (3.9 inch) GSD at 6562 feet (2000 meters) above ground level. A strong base-to-height ratio of 0.28 provides excellent stereo measurement accuracy. The nadir-looking monolithic PAN camera offers unmatched radiometric and geometric quality.
