Field
Work Friday September 6th, 2019
This was our first day of field work and
collecting data to use in Loc8, 3 flights were flown over the Purdue Wildlife
Area. The flights were designed to portray a search and rescue mission. Prior
to the flight we have taken “last seen” pictures of a team member to act as a
missing person. The clothes that were worn in those pictures were then placed
randomly in the field. Each flight was flown with similar parameters besides
overlap. We are now testing to see how overlap will affect our data and if Loc8
will have any problems identifying the objects.

This experiment used a Mavic 2 Pro and the
clothes set out in the field were all of different colors to test how darker or
brighter colors will be identified. Total flight times were recorded to test
which method is the fastest and compare a normal search and rescue mission with
a search and rescue mission using UAV’s. Times were also noted for when the
operator was able to visually spot each target during the flight.

We used DJI Ground Station Pro for mission
planning, Ground Station Pro allowed us to go down to only 10% overlap in the
flight, with the other flights being at 70% and 30% overlap. Due to the length
of Mission 3, the flight was stopped with two lines remaining in order to
safely land the UAV.
Research
In addition to our first set of flights, a
great deal of research was performed in order to get a better understanding of
the search and rescue field we are entering. We learned a lot about various
methods of SAR missions, as well as many of the limitations various operations
have encountered. We came up with a number of ideas that relate to each of the
articles we read about how to implement potentially better solutions to the
problems that the SAR community is facing. An annotated bibliography about our
research has been created, totaling our current 20 sources. That annotated bibliography can be found here.
