Machine vision technique to avoid alignment failure in space launch vehicleSuseetharan Vijayakumaran
Machine vision inspection technique is a new technique based on computer vision theories and provides a better way for inspecting the launch vehicle and its strapon misalignment to avoid failure. Compared with the traditional inspection techniques, the machine vision inspection technique has the
advantage of non-contact, rapid, fast on-line acquisition time, good flexibility and enhanced accuracy, etc. It will meet the requirement of modern space launch vehicle launching developments. The image of launch vehicle is captured using a camera and stored as a jpeg image. Then the stored image is analyzed for the orientation, angle and alignment of the Space Launch Vehicle along with its strapons.

This project examines the rate of erosion in Little Harbour, on the south-east coast of the Northumberland Strait. Coastlines were digitized using a series of airphoto mosaics from the 1970s to the present. The rate of change between digitized lines is measured using a script developed at the AGRG. Attributes are added to the data, classifying it by landform, waterbody, and angle. Results are examined to determine the overall rate of erosion, as well as to determine areas of increased vulnerability.
The Processing of the 1920's Survey Sheets of the City of Saint John, NB for ...COGS Presentations
Back in the 1920s, Mr. Murdoch and his crew surveyed the entire city of Saint John with great precision. The original sheets were scanned, which were black and white, and were made available on the Saint John open source website. Unfortunately these were not registered and individual sheets. These survey sheets would be very useful for City employees and interesting for the public.
After georeferencing each sheet to its correct location and scale, they were reference to the city property lines, with the help of ortho photos and city streets. Then each sheet was cropped to remove the border and surrounding text, using the Image Analysis window clip tool, and added to a mosaic dataset. The areas of overlap were clipped in the same way so that the areas of more detail was visible. This dataset was the input for the Copy Raster tool, which created one tiff file for all the sheets in 1 bit. The final mosaic was cleaned with the Raster Painting Tool to remove any redundant street names. This cleaned mosaic would then be uploaded to the online interactive City of Saint John Map as a layer for the public to see.
In conjunction with City of Saint John.
The 2016 Remote Sensing Field camp will take the form of two projects.
A low tech, low cost aerial photography project using visible spectrum UAV/Ultralight Aircraft mounted cameras as the sensor to demonstrate that relatively low tech, low cost solutions can achieve surprisingly good results when compared to more commercial systems.
A more high tech, high cost terrestrial LiDAR collect of a building or structure of historical or architectural significance.
The scope of a project will influence all other aspects of the project, including its cost, timing, quality and risk.

Using Panoramic Videos for Multi-Person Localization and Tracking In A 3D Pan...Fan Yang
3D panoramic multi-person localization and tracking are prominent in many applications, however, conventional methods using LiDAR equipment could be economically expensive and also computationally inefficient due to the processing of point cloud data. In this work, we propose an effective and efficient approach at a low cost. First, we utilize RGB panoramic videos instead of LiDAR data. Then, we transform human locations from a 2D panoramic image coordinate to a 3D panoramic camera coordinate using camera geometry and human bio-metric property (i.e., height). Finally, we generate 3D tracklets by associating human appearance and 3D trajectory. We verify the effectiveness of our method on three datasets including a new one built by us, in terms of 3D single-view multi-person localization, 3D single-view multi-person tracking, and 3D panoramic multi-person localization and tracking.

Geovisualisation and Analysis of the Good Country IndexCOGS Presentations
The Good Country Index is developed by Mr Simon Anholt, a policy advisor and strategist. It measures the cumulative contribution of 125 countries towards the benefit of the world in the technological, cultural, peace-related, world orderliness, environmental, prosperous, and health wellbeing aspects, thus making up the seven categories of the Good Country Index (Figure 1). Countries included in the index do not necessarily have to be good for their own citizens, because the index does not look at the existing infrastructure that make up the development and dynamics of countries, but rather, it only focuses on countries’ external outputs and resultant motives. On the contrary, there are plenty of other global indices (for example, Human Development Index, or Social Progress Index) that measure and rank countries in terms of their existing infrastructure. If we can substitute the category components of the Good Country Index with other global indices that correspond to the respective category component, we may be able to use the global indices as drivers to evaluate a country’s ‘goodness’.
This project entails a number of statistical methods for analytical purposes. Two types of analysis are carried out, the first type is non-spatial analysis which employs bivariate correlation to test for the existence of relationship between the Good Country Index components, and other global indices. Regression curves and decision tree rules are also obtained to employ predictive analysis on the Good Country Index in relation to other global indices as explanatory variables, with the main focus being made on the ‘Most Good’, and ‘Least Good’ countries. The second type is spatial analysis which includes spatial autocorrelation to test for the presence of underlying spatial processes by the Good Country Index, and global indices. If clustering is present, the degree of clustering is displayed. The cluster and outlier analysis, as well as hot spot analysis geovisualise the clusters, outliers, and hot and cold spots on various maps. Finally, grouping analysis is carried out to group similar countries into geographically compact clusters, and mapped.
This project focuses on exploratory analysis to find out if the use of global indices may be suitable as drivers to account for countries’ ‘goodness’ in the Good Country Index, as well as geovisualisation through mapping of the Good Country Index, in relation to its corresponding global indices. It must be greatly emphasized that this project will attempt to investigate levels of association (or correlation) between variables, as the use of explanatory variables does not necessarily result in causation, hence no strong judgement is made when attempting to relate the Index with other global indices.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

17. Scan Post-Processing - Faro
Scene (Joli)
Scans are imported into FaroSCENE where colour is
applied to points and the scans are registered together.
registration of 3D scans can be done three different ways:
● Target based- using targets such as spheres and walls
the scans
● Cloud to cloud- using point clouds that are similar
and/or close together.
● Top based- using inclinometer to determine z-axis
18. Registration method
After much trial and error the best registration
method for the project was determined.
Top based registration was used to roughly place the scans,
then using the correspondence view the scans were moved
to more accurate positions. Then cloud to cloud registration
was run to more precisely tie the scans together.
19. After scans have been properly registered and
colour has been applied you can view the point
cloud in 3D.
In the correspondence view individual
scans can be manipulated so they fit
together better allowing the cloud to
cloud registration to work better.
20. Save and Export
Initial post processing has been completed:
1. colour has been applied to the points from the pictures
taken at the same time
2. scans have been properly registered together
3. any “noise” has been removed from the scan
The scans can now be saved and exported so they are ready
for the next step of creating a 3D model and 2D floor plan.
28. Total Station
