The Meon Survey Partneship offers a wide range of photography services;
The above image was taken with a high resolution DSLR, control points were taken from a laser scan point cloud and the image was rectified to these control points.
The above image consists of several images using a DSLR, each image was rectified on the correct plane and stitched together, control points were taken from an electronic total station.
Created from a laser scanner, the wall was scanned in high definition and images from the scanner were applied to the point cloud, marginally reduced quality than from DSLR but faster.
Drones (UAV) can be used to capture images or video footage of roofs, upper parts of buildings, bridges, quarries and other inaccessible or unsafe areas. With specialist software and survey control these images can be stitched together and point cloud data created.
As mentioned above in the high level section, we can produce high quality rectified imagery from stitched together photographs, this can be used in conjunction with aerial imagery from drones/UAVs, or as a stand-alone project from ground level with an extending pole to capture the upper parts of the building or structure.
Control would need to be established to provide base coordinates, once these are established the images can be stitched together and point cloud data produced from this. As well as the point cloud data, 3D meshes and high quality imagery can be produced.

As mentioned above we can produce high quality 3D textured models using high quality photography and base measurements. We can use this to model small or large detailed features.
Below is a model of a statue in West Norwood Cemetery that we've created using only 45 images, the model can be improved significantly using more images.
Click on the image below and you'll be able to zoom in and rotate around the model, this can be exported to most 3D standards.
360° Virtual Images offer a unique way of visualising interiors or exteriors, using high-tech equipment and software, multiple high-quality images are taken and stitched together, this creates a seamless virtual image which can be viewed from a web page or as a movie file. The version shown below is a Virtual Tour of the National Trust property Uppark where you can move from room to room. (Please note that the virtual tours use flash, some browsers and mobile phones may need additional plug-ins)
