Geomorphological Analysis Using Unpiloted Aircraft Systems, Structure from Motion, and Deep Learning

IROS 2020poster

We present a pipeline for geomorphological analysis that uses structure from motion (SfM) and deep learning on close-range aerial imagery to estimate spatial distributions of rock traits (size, roundness, and orientation) along a tectonic fault scarp. The properties of the rocks on the fault scarp d…

ModQuad-Vi: A Vision-Based Self-Assembling Modular Quadrotor

ICRA 2019poster

Flying modular robots have the potential to rapidly form temporary structures. In the literature, docking actions rely on external systems and indoor infrastructures for relative pose estimation. In contrast to related work, we provide local estimation during the self-assembly process to avoid depen…

Monocular Camera Based Fruit Counting and Mapping With Semantic Data Association

RA-L 2019

In this letter, we present a cheap, lightweight, and fast fruit counting pipeline. Our pipeline relies only on a monocular camera, and achieves counting performance comparable to a state-of-the-art fruit counting system that utilizes an expensive sensor suite including a monocular camera, LiDAR and

Robust Fruit Counting: Combining Deep Learning, Tracking, and Structure from Motion

IROS 2018poster

We present a novel fruit counting pipeline that combines deep segmentation, frame to frame tracking, and 3D localization to accurately count visible fruits across a sequence of images. Our pipeline works on image streams from a monocular camera, both in natural light, as well as with controlled illu…

Counting Apples and Oranges With Deep Learning: A Data-Driven Approach

RA-L 2017

This paper describes a fruit counting pipeline based on deep learning that accurately counts fruit in unstructured environments. Obtaining reliable fruit counts is challenging because of variations in appearance due to illumination changes and occlusions from foliage and neighboring fruits. We propo

Towards autonomous phytopathology: Outcomes and challenges of citrus greening disease detection through close-range remote sensing

ICRA 2016

Unmanned aerial vehicles (UAVs) have the potential to significantly impact early detection and monitoring of plant diseases. In this paper, we present preliminary work in developing a UAV-mounted sensor suite for detection of citrus greening disease, a major threat to Florida citrus production. We p
