The Meon Survey Partnership offers a wide range of photography and photogrammetric services;
We can produce high quality rectified imagery from stitched together photographs, this can be used in conjunction with aerial imagery from drones/UAVs, cherry-picker or 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 a rectified image produce from this.
Example images below;
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.
The example below is of Colston Hall in Bristol, this was created from hundreds of photographs from ground level and a cherry picker for the higher levels, these images were stitched together and tied to control points, the quality of the final product is staggering.

The art of Photogrammetry dates back to the mid-19th Century and surveys were created using stereo plotters, modern day technology and software means that surveys can now be created using a combination of aerial and land photography quickly and efficiently.
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 photogrammetry software and survey control these images can be stitched together and 3D point clouds and 3D meshes created.
We are fully operational and have permission to fly from the CAA (PfCO).
The Meon Survey Partnership have the technology and skillsets to produce high quality 3D textured models using high quality photography and base measurements. We have our own in-house UAV/drone team and high resolution camera equipment to produce 3D pointclouds and textured mesh models of large or small sites, difficult to reach areas and buildings which need high quality models, the methods can be combined with land based laser scanners to produce point cloud solutions or a mixture of ground and aerial photography for true colour representations. We have a few examples below but if need more information please do not hesitate to contact us.
Click on the images below and you'll be able to zoom in and rotate around the model, this can be exported to most 3D standards.
The textured model below was created using only 45 images from a high resolution DSLR, by zooming in on the sketchfab player below you can see there is already a substantial amount of detail, this can be increased by taking more images.
Control points are taken using either electronic theodolite or laser scanner and a point cloud is constructed, from this a coloured 3D mesh is created.
The 3D model below was created by using a UAV/drone to take around 150 high quality photographs, these were then stitched together to create a point cloud and from this a coloured 3D mesh was created. Flight time was around 10 minutes, this method would work extremely well on large areas where a quick 3D model is required. For more complex areas or buildings, photos taken from the ground can be used to enhance the quality of the model.
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. Click here to view a version which uses flash.
