Post-Doctoral Research Fellow - BRDF correction of Image
Data for Vehicle or UAV Mounted Sensors

College: UCD College of Engineering and Architecture
School: UCD School of Biosystems and Food Engineering
Post Title: UCD Post-Doctoral Research Fellow Level 1
Project: GeoHub: BRDF correction of Image Data for Vehicle or UAV Mounted Sensors
Post Duration: 15 months
Reports to: Professor Nicholas Holden
HR Reference No.: 009469
HR Administrator: Sinead Gillen

Position Summary

Recent growth in agricultural imaging services has predominantly been in platform and sensor hardware associated with UAV and vehicle mounted sensors. For applications to keep pace with hardware, the market requires tools for real-time automated data management, specifically for quality, consistency, integration, compatibility and automated interpretation. GeoHub will develop software tools aimed at providing normalized/ corrected image data, thereby removing the roadblock of data inconsistency associated with UAV based platforms in sectors like precision agriculture.

The purpose of this role within the GeoHub team, is to develop the tools and software associated with the correction of Bidirectional Reflectance Distribution Function (BRDF). BRDF over non-Lambertian targets, such as arable crops, is a particular issue in the application of UAV based data in precision agriculture. The successful candidate will utilise data from various sensors and platforms across various agriculture study plots during the development process. This is a fantastic opportunity to be part of an innovative and dynamic team in the development of cutting edge commercial software associated with UAV and vehicle mounted visible and Near-Infrared imaging.

This is a research focused role, where you will conduct a specified programme of research supported by research training and development under the supervision and direction of a Principal Investigator.

The primary purpose of the role is to further develop your research skills and competences, including the processes of publication in peer-reviewed academic publications, the development of funding proposals, the mentorship of graduate students along with the opportunity to develop your skills in research led teaching.

In addition to the Principal Duties and Responsibilities listed below, the successful candidate will also carry out the following duties specific to this project:

  • Field based data collection of canopy architecture metrics
  • Development of new or adaption of existing BRDF correction models and techniques
  • Integration of tools and methodologies into the Python or C/C++ coding environment
  • Assist in the development of other correction tools associated with GeoHub
  • Report to Enterprise Ireland with respect to deliverable's and milestones associated with GeoHub
  • Conduct a specified programme of research and scholarship under the supervision and direction of your Principal Investigator.
  • Engage in appropriate training and professional development opportunities as required by your Principal Investigator, your School or Institute, or the University.
  • Engage in the dissemination of the results of the research in which you are engaged as directed by and with the support of and under the supervision of your Principal Investigator.
  • Engage in the wider research and scholarly activities of your research group, School and Institute.
  • Mentor and assist, as appropriate and as directed, the research graduate students in your School and Institute.
  • Carry out administrative work associated with your programme of research.

Selection Criteria

Selection criteria outline the qualifications, skills, knowledge and/or experience that the successful candidate would need to demonstrate for successful discharge of the responsibilities of the post. Applications will be assessed on the basis of how well candidates satisfy these criteria.


  • PhD in the areas of image processing, remote sensing, optical engineering, photonics, applied optics
  • Experience in image processing/ correction of visible and NIR data
  • A demonstrated commitment to research and commercial outputs
  • An understanding of the operational requirements for a successful research project
  • Evidence of research activity (publications, conference presentations, awards) and future scholarly output (working papers, research proposals, and ability to outline a research project.
  • Excellent Communication Skills (Oral, Written, Presentation etc)
  • Excellent Organizational and Administrative skills including a proven ability to work to deadlines
  • Proven ability to work as an individual but also work within a team

The PD1 position is intended for early stage researchers, either just after completion of a PhD or for someone entering a new area for the first time. If you have already completed your PD1 stage in UCD or will soon complete a PD1, or you are an external applicant whose total Postdoctoral experience, inclusive of the duration of the advertised post, would exceed 4 years, you should not apply and should refer to PD2 posts instead.


  • Experience in applied optics and photonics, BRDF correction and/or electro-optics
  • Experience in the application of PROSPECT, SAIL or PROSAIL plant canopy spectral and directional reflectance models.
  • Experience in setting own research agenda
  • Software development skills in either Python or C/C++
  • Industry collaboration or experience in image processing
