The data contained in this archive are images processed to provide context to LiDAR scans held in archives BGS230126 and BGS230127.
The TLS was combined with a high-resolution digital camera and a high precision differential Global Navigation Satellite System (GNSS) to obtain coloured point-clouds. Colour temperature was captured at 4550 K for every image, exposure was adjusted as necessary based on the light conditions each day. The Camera was positioned such that its lens is centred at the mirror position of the TLS and is rotated around this point using a Nodal Ninja panoramic tripod head. The camera captured 36 images per scan to create a 360 degree panoramic image which was combined with the TLS scan in post processing: there were 12 angles captured per panorama, 6x 60 degree horizontals intervals and 2x vertical intervals at -10 degrees and +25 degrees, each with a set of bracketed exposures (3 images taken at -1ev, +0ev and +1ev relative to the required exposure at the moment of capture). The images were combined in 360 degree HDR panoramic images using PTGUI 11. These images were roughly 14000x7000 pixels in size (98 MP), 8 bit PNGs. The panoramic images were then adjusted in Adobe Lightroom 2019, primarily to balance the exposure and colour-temperature over the set of panoramas.
