Using deep learning to detect an indicator arid shrub in ultra-high-resolution UAV imagery

Article link: Using deep learning to detect an indicator arid shrub in ultra-high-resolution UAV imagery

My PhD research is in collaboration with Bush Heritage Australia. The second chapter of my thesis concerns the use of UAV imagery for gathering species-composition information, a component of biodiversity where measurement has typically been restricted to on-ground methods.

I used high resolution UAV imagery and deep-learning-based object detection models to automatically detect pearl bluebush (Maireana sedifolia) in UAV orthomosaics. The aim of the research was to assess the feasibility of this approach for use in monitoring programmes, as well as how detection accuracies were affected by the deep learning models chosen, image resolution, and monitoring site.

Deep Learning in ArcGIS Pro using your GPU

ArcGIS Pro includes built in tools that allow end-to-end deep learning, all within the Arc interface – from training sample labelling, through model training and final image classification / object detection. This removes the need for coding and installing the correct versions of the required libraries for machine / deep learning in Python.

However, training deep learning models is an extremely processing-heavy task that requires the use of your GPU to even be slightly feasible in terms of processing time.

Although, Deep Learning in ArcGIS Pro is not possible straight out of the box. This post will walk through how to get everything set up, based on my experience with ArcGIS Pro 2.8/2.9 and the graphics cards listed below. Processes / software versions are sure to change in the future, so I will try and keep the instructions as general as possible.

Meet The Team – Angus Retallack

Growing up in suburban Adelaide, I never had any particular hobbies or interests, other than being generally hands-on. Going through high school, as with most people, I still had little idea of what direction I wanted to go – so I took the “I don’t know” option and applied for a BSc at Adelaide Uni.
