====== SASS Project Weekly Progress ======

The **Streetscape Application Services Stack (SASS)** project focuses on real-time data collection and synchronization from multiple urban sensors, including Reolink cameras, IMUs, and GoPros. Below is a week-by-week breakdown of progress.

===== Week 1: Project Setup and Goals =====
  * Defined core objectives of the SASS system: synchronization, modularity, and smart city relevance.
  * Introducing ourselves, setting up the initial team structure, and responsibilities.

===== Week 2: Reading Papers about Multi-modal Fusion =====
  * Discussed with Professor Ortiz about making SASS identify a person in need more discreetly.
  * Read additional papers to check the feasibility of the proposed framework.
  * Read about multi-modal fusion.

===== Week 3: System Design and Website Development =====
  * Began developing a website to present a portfolio about the project. 
  * Set up a System Design Diagram for the data collecting phase.
  * Set up all the cameras we are going to use and look into the Sensorlogger App.

===== Week 4: Devices + IMU Merge Efforts =====
  * Installed Reolink, GoPro cameras, and the SensorLogger App, and basic data collection scripts for each of them.
  * Investigated frame-by-frame video analysis from Reolink and GoPro.
  * Began efforts to merge IMU and Reolink outputs into a unified logging format.
  * Same with the GoPro.
  * Integrated IMU sensors with custom Python-based `sensorlogger` script.

===== Week 5: Synchronization Debugging =====
  * Analyzed misalignments in timestamps between sensor types.
  * Attempted to merge all Python files into one. As a result, the Reolink/SensorLogger file and the GoPro/SensorLogger file were used separately.
  * System Design Diagram was updated. (As shown in the Google slide).

===== Week 7: Infrastructure and Database Discussions =====
  * Explored alternatives to flat CSV files; began shifting toward a structured database backend.
  * Discussed metadata tagging and retrieval use cases.
  * Updated diagrams to reflect router roles, LAN/IP separation, and new sensor locations. 
  * Started experimenting with YOLOv5 object detection to help define the best camera angles for installations.

===== Week 8: Unified Logger Development =====
  * Finalize camera alignment with YOLO results.
  * Started collecting data.

**Next Steps**
  * Still collecting data. 
  * Test the unified data logger under full deployment.
