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.

​SASS Week 1

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.

​SASS Week 2

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.

​SASS Week 4

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).

​SASS Week 5

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.
