We conducted a live test of the walk sign image classifier using the actual camera and with the model running on the Jetson. The performance did not meet our specifications, so we are now working on improving that model, as detailed in Max’s status report for this week. The good news is that the camera quality is decent, and despite some initial issues with linking the video stream to the model, everything seems to work smoothly.
The object detection models all seem to work reasonably well on the images sampled from the live video feed. Not only do the bounding boxes accurately center on the relevant objects, but the video feed is clearly high-resolution enough for the model to work correctly. As such, it has been straightforward to visually confirm that the object detection component is working as well as it did during our extensive testing phase, and we can focus our efforts on refining the navigation submodule logic.
Concerning hardware, finishing touches for the chest mount are arriving this weekend. This includes standoff components and the padding. The primary material of the chest mount has been changed from 6mm plywood to 3mm acrylic. This decision was made for weight, flexibility, compatibility (with mounting hardware), and aesthetics. We also have obtained our power supply, which reads an estimated 11-hour battery life. This should be more than enough to cover the day-to-day usage of most users.
