Objective To build a low cost motion detection device that will detect a human presence.
Low cost components Advanced Capabilities for Interfacing Initial Constraints Low cost components Advanced Capabilities for Interfacing
Initial Constraints → Results Low cost components Advanced Capabilities for Interfacing → Components combined price under $20 → Can program in Arduino IDE and AVRdude (command line terminal)
Main Components Adafruit Trinket Mini Pinhole camera Additional standard electronic components Pinhole camera
Outline Design test circuit Practical interfacing with microcontroller and camera
Outline Programming for: - Successive snapshots - Data Capsulation - Image analysis Troubleshooting/debugging - (Ongoing)
Data Capture Due to processing power of hardware: - Utilize minimal amount of data required to achieve motion detection
Data Capsulation Due to processing power of hardware: - Utilize minimal amount of data required to achieve motion detection
Image Analysis Comparison of two subsequent snapshots from the video feed: vs. Data Output
Progression Initial interfacing with camera Scripts: - Snapshot capture - File handling/Data Capsulation
Obstacles Processing information locally -Remote computer for data analysis? Tuning for sensitivity -Detection for people vs anything moving in the frame
