DESIGN PROFESSOR MEETINGS
May 15th, 2019
During the first meeting for Senior Design, we discussed what parts have been ordered. We described the tests that we did with the Raspberry Pi and the Pi Camera. We talked about the basic facial recognition that we performed after downloading and installing OpenCV. Dr. Ejaz informed us of the website requirements and what we need to add and how to modify the website.

For our second meeting, Dr. Ejaz explained, more in depth, the requirements for the website. We discussed using Haar Cascades to 'train' the Pi to recognize specific faces. We informed him of the progress of the TL-201 deadbolt installation and what we plan doing to have the Pi properly communicate with it. The power source and its limitations were also discussed. He informed us that if the power-bank is not providing enough power, then we need to determine an adequate power source soon.

On May 29th, with Dr. Ejaz, we discussed the progress of the Haar Cascades facial recognition software on the Raspberry Pi. Iqbal is still is working on the software, but Dr. Ejaz clarified some of the concepts regarding why the negative images are used with the algorithm. We updated him on the progress on the TL-201 Electronic Deadbolt. We successfully installed the deadbolt and used the pin number '2019' to lock and unlock it. We informed Dr. Ejoz of our first method of reading the signals coming from the circuit board for the pin pad to the circuit board for the locking mechanism. This is to use the 40-pin GPIO on the Raspberry Pi as receiver for the signals from the TL-201 pin pad circuit board. Lastly, we also discussed the simple test using the Raspberry Pi on the Hi-lucky Solar Power bank.

On June 5th we discussed the issues we were having with the training of the Haar Cascades algorithm and reading the signals through the electronic deadbolt. The last step in the Haar Cascades was giving the same error, 'not enough samples in the vector file', even after adding more samples. We informed Dr. Ejaz that we were going to research and try the Eigen Faces algorithm. He sent us a previous Senior Design Report on 'Facial Recognition within Matlab' using Eigen Faces. Catalina let Dr. Ejaz know what Miguel, her security advisor said about the serial connection within the electronic deadbolt. It's gonna be difficult to intercept the serial connection, so we decided it would be best to wire the number pad and motor directly into the Raspberry Pi via the GPIO connections.
