The 4-2K is our new digital camera that is set up for use with the LiDAR system. The camera is controlled through the same program that controls the LiDAR and digital images are captured simultaneously as the LiDAR is scanning.
This allows us to drape images over the LiDAR processed data for better planning, mapping, and design products and to help us produce orthorectified images
Camera lens focal length = 55mm.
Camera lens f/stop 4.0.
37 degrees footprint.
Maximum frame rate = 1 frame every 2.5-2.7 seconds.
Operating altitude for RHD: 10,000 ft MSL.
The image plate consists of a color 4077 x 4092 pixel CCD array. Each pixel is 9 microns in size. This results in an image size of 36.693 x 36.828 mm. The orientation of the CCD in the camera is such that the long axis is in the flight direction.
Here are some examples of the quality of photography we get with the digital camera (note: these images have been compressed for viewing on the web and have decreased the quality of the image, click on the image for full size view).
