RMK Dx

Intergraph offers the RMK DX, the first super medium-format digital aerial camera that uses a single monolithic camera head to produce extreme wide-ground coverage.
 
ONE SINGLE PAN CONE – ONE LARGE CCD
The RMK DX includes one large 12.2k x 11.4k charge-coupled device (CCD), exclusively customized by DALSA for Z/I Imaging®’s digital camera technology. The RMK DX 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 RMK DX image data post-processing does not require CCD stitching or image mosaicking.

ADVANCED DESIGN
The RMK DX is based on the RMK D camera design. It includes five nadir-looking camera heads – four multispectral cameras for red, green, blue, (RGB) and near-infrared (NIR), and a fifth highresolution PAN camera head. Each multispectral camera has a 42 MPixel CCD (6800 x 6096 pixel) with 7.2 micron pixel size and a dedicated color filter. The focal length for the multispectral cameras is 45 millimeters (mm). The PAN camera includes a 144 MPixel CCD (12240 x 11418 pixel) with 7.2 micron pixel size and 92 mm focal length. The PAN camera has an infrared cut-off filter to remove the spectral wave length beyond 710 nm.  

INCREASED PERFORMANCE
Our RMK DX is a high-performance digital camera system. It has a two-second frame rate to maintain high-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 218 knots). The PAN/color ratio of 1:2 provides highradiometric quality images for RGB and color-infrared (CIR). The long focal length and small pixel size delivers high-resolution image data (15 cm GSD at 1917 meters above ground level). A strong base-to-height ratio of 0.35 provides excellent stereo measurement accuracy. The nadir-looking monolithic PAN camera offers unmatched radiometric and geometric quality.

IMAGE DATA POST-PROCESSING
Image data post-processing for RMK DX is based on the DMC post-processing software. Development has implemented the RMK DX sensor model. The user interface is unchanged, which eliminates any training effort for existing DMC customers. Final image format after post-processing is 11712 x 11200 pixels.

MODULAR AND COMPATIBLE
RMK DX is compatible with all existing peripheral devices used for RMK TOP, DMC, and RMK D, which include Z/I Mission planning software, Z/I Inflight sensor management system, solid state disks (SSD) storage cartridges, Readout Station, T-AS mount, and Z/I Mount. In addition, a new adapter plate for the new generation of Z/I Imaging cameras allows you to use a wide range of different RMK DX™ CAMERA SYSTEM inertial measurement unit (IMU) sensors. You can upgrade your RMK D camera and convert it into a RMK DX by installing the PAN camera head.
