Sammanfattning
This thesis presents a ground-based solution for measuring snow depth in real-time,
specifically applicable to a vehicle. The primary motivation behind this study is
the desire to enhance efficiency in snow-related domains through precise monitoring
of snow depth. Typically, ground penetrating radars (GPR) have been used in
conjunction with human operators to monitor ice and snow layers. However, this
approach incurs costs in terms of both time and performance, leading to potential
errors and uncertainties.
To address these challenges, this research explores the integration of artificial
neural networks with GPR technology, aiming to boost their effectiveness in measuring
snow depth. Various sensors, simulation methods, and neural network models
were examined to develop high-performance solutions. Through extensive testing,
a trained convolutional neural network achieved an accuracy of 1 cm on controlled
experiments, showcasing the potential of combining these approaches. By enabling
the system to conduct 20 depth measurements per second with this level of precision,
a real-time solution for measuring snow depth is achieved.
Furthermore, the thesis proposes that incorporating the propagation speed of
signals through the measured snow can further enhance the reliability of these monitoring
systems. Such enhancements would provide valuable data to various fields
that rely on accurate information about snow depth. By improving the overall efficiency
and accuracy of snow depth measurements, this research opens up possibilities
for advancements in snow-related domains.
