About the Project

Introduction

An opportunity to apply for a funded full-time PhD in the Centre for Machine Vision (CMV), School of Engineering, UWE Bristol. The studentship will be jointly funded by UWE Bristol and Zenotech Ltd.

The CMV is located within the Bristol Robotics Laboratory (BRL), a joint venture between UWE Bristol and University of Bristol. The CMV specialises in real-world applications of computer vision and machine learning for the realisation of working prototypes and demonstrators, with a strong emphasis on 3D imaging and analysis, data capture, and modelling. This studentship will also receive support from the world-leading aerodynamic and software development teams at Zenotech, such as relevant datasets for project case study, and general domain expertise in Computational Fluid Dynamics (CFD) meshing.

The expected start date of this studentship is 01 April 2023.

The closing date for applications is 06 December 2022.

About the studentship

Engineers and scientists are often faced with immense challenges when examining and processing complex 3D simulation data. This can be due to complexity and variability in the data representation in the 3D space, the potential large scale of the data itself, a high density of data points, and the inconvenience of data visualisation leading to unintuitive human perception of the 3D data.

A typical example is the production of a Computational Fluid Dynamics (CFD) mesh based on aircraft geometry. A significant bottleneck in this activity is caused by the vast amount of time that CFD engineers spend on manually changing mesh rules and geometry to achieve an acceptable solution. Computer vision and machine learning, through enabling automatic detection and localisation of 3D objects in complex 3D point clouds, has tremendous potential for automating and improving the CFD meshing process.

This study will investigate feature-based registration of point clouds and deep-learning-based 3D object detection in point clouds, in order to automatically select and tune mesh criteria for every type of aerodynamic device together with local contexts of an aircraft’s geometry.

Funding

The studentship is available from 1 April 2023 for a period of three and a half years, subject to satisfactory progress and includes a tax exempt stipend, which is currently £17,668 per annum.

In addition, full-time tuition fees will be covered for up to three and a half years (Home and Overseas).

Eligibility

This will be a three and a half year full-time commitment. The project is ideal for a self-motivated and enthusiastic student with a good honours degree (2:1 or equivalent, or above) in a relevant field, and evidence of further study at Masters level or equivalent. Please note, acceptance will also depend on evidence of readiness to pursue a research degree. Knowledge and experience of machine learning and coding (such as C++ or Python) is essential. Expertise in processing point cloud data is desirable.

International applicants are welcome to apply. A recognised English language qualification is required.

How to apply

Please submit your application online. When prompted, use the reference number 2223-APR-CATE11.

Supporting documentation: You will need to upload your research proposal, all your degree certificates and transcripts and your proof of English language proficiency as attachments to your application, so please have these available when you complete the application form. 


References

References: You will need to provide details of two referees as part of your application. At least one referee must be an academic referee from the institution that conferred your highest degree. Your referee will be asked for a reference at the time you submit your application, so please ensure that your nominated referees are willing and able to provide references within 14 days of your application being submitted.
