This week, I focused on the refinement of the chest mount, as well as some integration and finalization. For the chest mount, I worked on calibrating the designs for comfort. Now, the main part of the chest mount is made of 3mm acrylic (vs the 6mm plywood previously used). This allows for much smoother contact with straps, as the previous design had issues with fraying fabric. It is also much lighter and more flexible, making the design more comfortable to wear. The standoff components are arriving tomorrow, which will let me mount the components to the chest piece.
In other news, the power bank arrived this week. It took a while for this, as I had to ensure that the battery could consistently output the required wattage over the ports (an issue we ran into with existing power supplies). This allowed us to take the system out for testing, albeit awkwardly, as we held all the components, laptops, and wires by hand. The results from this testing were not great, as the classifiers could not correctly detect the correct signals most of the time. As such, we recorded a bunch of new data, which my teammates are using to retrain the models to make them more accurate.
Another issue was that my default settings for the camera were lackluster. I believe that with some fiddling, I can get a better picture quality for the models. However, this higher resolution may not help or may even cause the models to take longer to run. Ultimately, more testing needs to be done for this. On a more positive note, the red tint issues from last week have been completely resolved using a .isp file I found online.
Regarding the schedule, I am more or less in sync with the Gantt Chart (which was updated during demos). I aim to continue working tomorrow to get all the components mounted to the chest mount. I expect to work through some issues with screw hole dimensions, so I have blocked out a decent chunk of time for iterating through designs.
