- At the beginning of the week, I worked with my group to prepare for our proposal presentation. In addition to practicing with my group, I went through the slides a couple of times myself to better prepare for the presentation.
- We are trying to buy a camera soon so we can start collecting data from Professor Dueck’s students. Since the camera depends on the camera stand, I fleshed out the requirements for the camera and the camera stand. These diagrams/drawings and calculations are necessary to justify which camera we purchase.
- The stand should be easy to use, and portable.
- The stand should capture the entirety of the keyboard length for different types of pianos.
- For upright pianos, the camera stand can be placed on the flat top of the piano.
- However for grand pianos, if they are played open then there is no flat top; therefore we are looking into creating a clip to attach the camera to the music stand. We should be wary of the risk of the camera falling backward and into the piano, thus causing damage to the strings.
- There is more variance when it comes to electric keyboards. At the time, I could not think of many ways to create a camera stand to position the camera. Currently, I envision keyboard players will be responsible for providing a flat surface (e.g. table) behind the keyboard to place the camera stand on.
- Many electric keyboards have very flimsy music stands, so it could be difficult to clip a camera onto it. They are also sometimes free-standing (no flat surface nearby to place it on). We don’t want to create a camera stand that would rest on the ground since it would have to be very tall to capture the full length of the keyboard from overhead. It would be difficult to create a stand that is very tall, adjustable, strong enough to hold the camera, and meet our use case requirements of being quick to set up and portable.
- Since the camera stand needs to be fairly tall and attached to a clip, it should be as light as possible. For this reason and to minimize costs, we decided to opt for a webcam.
- Another concern is camera compatibility with the KR260, which we are waiting for Varun to verify. We know that the camera must have a USB output to connect to the FPGA though.
I did some calculations using the field of view of variously priced cameras and the length of a piano keyboard to get a feel of how tall the stand would need to be and which camera we should opt for.
- I also started Varun’s KV260 setup tutorial. I estimate that I am ⅓ of the way through.
I am currently still on schedule.
Next week I plan to finish the KV260 setup guide and install the packages necessary for media pipe.
