Shahzad did do a good job and particularly came up with a working system within 8 month. To build the current setup he needed 2 month. I would like to make a few experiments. If they turn out as expected I would like to start from scratch. Thus throwing away two month of work.
Planned System Setup:
- Android Phone with jailbreak running Debian.
- Data recored on USB Stick connected to it.
- Camera Connected to it via USB. Camera without computing capabilities.
Advantages:
- Our code is written for Linux. In the current setup it is written for the camera. And if the camera is not available anymore we have to rewrite our code.
- The size of the camera is much smaller
- The camera does produce much less heat. Likely at least since it is probably the DSP that is generating most of the heat.
- We can bend the cable between the camera and the android phone as we like
- The power consumption will be significantly lower
- We don't need any IMU anymore. Saves us a lot of money
- We can by a much cheaper camera.
Expected Problem:
- Will it work with the phone we got.
- In order to do real time on Linux we need to write kernel code. Development is very slow since if the code crashed we will have to restart the machine. I might also hose the phone in that. We maybe its not really that dangerous, but you never know.
- Will an open source IMU running on Android be good enough to work with the post processing pipeline.
Planned Experiments:
- write a hello world kernel module and make it run.
- Set up a software IMU in the phone. And try to get an Idea in the precision.
- Experiment on the realtime issues on the phone
