Welcome to Hugh’s world of panoramas …
If a picture is worth a thousand words then a panorama must be worth ten thousand, especially a 360° (or spherical) panorama where you can look all around and in any direction you wish to.
The spoken and written word is interpreted differently by each person as they visualise in their own minds the scenes described.
Images, paintings and photographs can more accurately portray scenes, views and vistas, but these are controlled by those producing them as they select orientation and perspective.
Still images leave the viewer with many unanswered questions:
How does a particular view relate to others in the same vicinity?
What do you see if you were to turn left, right or completely around?
How does a particular feature fit in the landscape?
Full 360° Panoramas provide the answer.
As explained in www.hugh360.co.uk anyone with a camera and related software can create their own panoramas and 360° panoramas, and today there is a myriad of dual and multi-lens cameras than can create 360° panoramas simply and easily so there are no longer the skill requirements needed only a few years ago.
My skills developed in recording and creating 360° panoramas, which can be incorporated into websites by their authors, using the equipment and software as it developed, but today the opportunity to create 360° panoramas is available to everyone although the skill sets of the past are still required to create high resolution panoramas.
If you have any questions relating to this fascinating and useful subject my contact address is email@example.com.
The prime object of this site is to promote 360° (Spherical) Panoramas and to show how they can be used and contribute to promoting your own scenarios.
As the technology evolves acquiring 360° Panoramas and creating Tours continues to be ever more available and affordable.

|Use 360° Panoramas for ‘Real Life’ Measurement
PaMe provides two applications for getting measurements from 360° Panoramas.
PaMe Wizard is a Krpano add-on providing a ‘measure tool’ in a ‘Krpano driven’ Virtual Tour. This full version contains four ways of measuring, with the ability to save the calibrations (which can be ‘locked’) and provide ‘real time’ measurements.
PaMe Light is a web based tool that allows you to just drag and drop your 360° Panoramas from your desktop.
This light version has three ways of measuring.
|PaMe – Measure from 360° Panoramas
Some notes on using PaMe.
PaMe is straightforward to use with ‘on screen’ instruction and good tutorials so there is NO ‘steep learning curve’.
PaMe Light is excellent for experimenting with the application before committing to purchase PaMe Wizard.
|Finding the Nodal Point of a Lens
For a lens to be used effectively for Photographic Intersection the location of the Front Nodal Point must be accurately determined.
|The No Parallax Point
Some notes on the No Parallax Point and using it for 360° (Spherical) panoramas.
|The Nodal Point
The case for the Nodal Point and usage of the term.
|Making the Panoramas
If a picture is worth a thousand words then a panorama must be worth ten thousand, especially a 360° interactive panorama where you can look all around, but how are they created?
Nodal Ninja is a specially designed spherical tripod head allowing the photographer to adjust a camera and lens so the “entrance pupil” (front nodal point) is exactly over its correct rotational axis.
Their web site states “The lightest smallest panoramic tripod head on the market today. Nodal Ninja is a solution for both amateurs and professionals alike that seek precision, portability, reliability as well as top notch support.”
|Measurements from 360° (Spherical) Panoramas
360° Panoramas have properties that can enable Angles (both Horizontal and Vertical) to be derived from various projections in the same way as using a Theodolite.
The Angles measured from two or more 360° Panoramas can be used to derive Measurements and Co-ordinates.
|Accuracy for Intersection Solutions
The accuracy for a point measured using an Intersection method is determined by three inter-related factors:
the separation of the Stations (Base Line),
the Angle of Intersection and
the Precision of the Angular Measurements.
|Single Lens v Multi-lens Cameras for Accuracy
Today there is a plethora of multi-lens cameras for capturing 360° panoramas which have the advantage of a single shot rather than taking a set of shots, but would these have the accuracy required for measurement as there are two fundamental differences between the two methods.
Tp make panoramas with a camera with a single lens it is usually mounted on a panohead and rotated about the NPP but with a multi-lens camera this is physically impossible.
|Samsung Gear 360 + Insta360 ONE X
The result of the investigating the accuracy of using a Samsung Gear 360 for measurement, where the Samsung Gear 360 was rotated around its central vertical axis and stitched with PTGui, which provided a more accurate result than combing the hemispheres with ActionDirector, raised the question “Would a better result be achieved if the Samsung Gear 360 was rotated about the NPP of the lenses?”
|Using 360° iSTAR Panoramas to add Detail to an HDS Point Cloud
Real world colour can be added to the points in a Point Cloud from co-centric 360° (spherical) panoramas and some users have found that it is also beneficial to take additional 360° panoramas. This task takes this one stage further and uses 360° panoramas to add detail to a survey initially made with an HDS Scanner.
|Using Panoramas to add Colour to HDS Point Clouds
The “native” colours for an HDS (High Definition Survey) point cloud are based on the reflectivity of the surface the measurement is made to and are determined by the intensity of the received reflected laser beam. Whilst this information is useful in its own right it is often desirable to have the points with their “natural” (RGB) colours. This is an overview on using 360° Panoramas to add natural colour to an HDS Point Cloud.
|The Use of Spherical (360°) Panoramas for Photogrammetry
Spherical Panorama projections are suitable for the extraction of measurements to compute the 3D co-ordinates for points from two or more panoramas.
The mathematics involved is much more straight forward than that required for using photographs for Stereo Photogrammetry and Photographic Intersection Horizontal and Vertical angles are easily measured in an Equirectangular projection to provide the same data as if a theodolite was used at the same location.
|Spherical Panoramas for Photogrammetry
3D measurement techniques are readily available, but low cost solutions are needed for applications where only a small quantity of data is required.
Measurements can be made from Spherical Panoramas using available techniques, but these are time consuming, error prone and laborious, so this is an appeal to those with skills in software development in the fields of digital imaging and the mathematics to compute intersecting rays in space to provide a viable and cost effective solution.
|Using Thermal Images to create a 360° (Interactive) Panorama for use with HDS Point Clouds
A report on an investigation into the possibility of using images from a Thermal Imaging Camera to create a 360° (Interactive) Panorama to generate the Cube Images to attach the colours from the thermal images to an HDS (High Definition Survey) Point Cloud.
