Ing. | Vertriebsingenieur; Beim Erlenwäldchen 8 | D-71522 Backnang Integrated Camera System The Trimble X7 integrates a smart coaxial camera system with 3 x 10Mpx cameras. Resolution for each image is 3840 x 2746 pixels, each with a specific field of view to optimize coverage and productivity. The coaxiality of the cameras is given by mechanical design and the alignment of their optical axis to cross the center of our gimbal system to minimize parallax between images and scans. Image acquisition time depends on the number of images selected. You have the option to capture 15 or 30 images. In normal lighting conditions, it takes one minute to capture 15 images and two minutes to capture 30 images with auto exposure. The 15 image capture takes pictures from six positions (rotating horizontally in 60° increments). The 30 image capture takes pictures from 12 positions (rotating horizontally in 30° increments). 30 images will enhance scan colorization and panorama image quality, especially in complex environments where occlusions are more prevalent. More images will improve coloring and coverage however image capture and processing time will increase. 15 images are sufficient in simple environments where there are fewer occlusions and good quality coverage is possible. There is also a High Dynamic Range (HDR) imaging mode that acquires two additional images at different exposures from each position and merges the results to achieve a higher range of luminance for more color and detail in bright and dark areas. HDR will take 3 minutes to capture 15 images and 6 minutes to capture 30 images.
