Our promo video is done! Our demo video....you're probably not as interested in seeing as it gets kind of technical. But recording for that is done too :)


We've also been doing some more testing. We've found that nighttime driving is quite difficult for the model. Specifically, headlight glare really affects the model as most of the car is now obstructed by light. Because of this, the model isn't able to make the connection that the headlights are coming from a vehicle and miss it. We're going through some route to fix this. To ensure these are considered in evaluation, we've gone and collected more nighttime driving data to evaluate against. Unfortunately, the symposium is coming up on the 30th so we're not sure if we'll be able to perfect nighttime driving before then.



So we've been testing...a lot.


TL;DR

We've made sure the system is easily installable. We've tested the machine learning model to make sure it's accurate and have made some tweaks. We've also taken this out on the road and seen some very good results.


What Happened

We recorded how to install the system - this involved disassembling and reassembling. This confirmed that the system was easy to install. We clocked in at under 15 minutes and almost zero physical modifications to the car.


We also did a lot of testing. We took the system out for a few drives to collect our test set data then annotated all of it. Our annotations included drawing boxes around the hazards and labelling them. We could now test our model and gain an actual numeric metric showing us how good the model is. We're currently sitting at around 99% accuracy but this is somewhat optimistic because all the data we have is in the day time in perfect clear weather conditions. We will be collecting more data as the weeks go by, including nighttime data, and if possible, snow and rain.


What's Next

More data collection, more testing. We'll also be recording our marketing and demo videos.


Of all the days we could've decided to build our system...we chose the coldest, windiest day of the week...


TL;DR

Our prototype is constructed and tested on the car! All the camera mounts were installed successfully and the Jetson powers up without any brownouts. In an initial test, the results looked really good and we'll have a video of that soon!


What Happened

We met on March 1st for a cold build session where we constructed our prototype. Due to COVID, we were all in masks outdoors and socially distancing - which made for an interesting build session. It also didn't help when the wind picked up and snow came.


Nonetheless, we were able to install our system easily - as was the intended design. The cameras all hooked up perfectly and the Jetson worked as intended.


During testing, the snow actually became a beneficial aspect of the day as we were able to test our system in overcast and snowy weather at the same time. From the image shown above, the system works great regardless of those weather conditions.


We also took the car out for a short drive to show the software working in a real-life scenario. We'll have the video showing that result soon!


What's Next?

Video making time. We'll be making some short videos, one to market the product and another to show off the more technical aspects of the project.
