Evaluation of Several Tesla Dashcam Angles for Model 3 and Y Via Reverse Project Photogrammetry

Tesla Model 3 and Model Y vehicles come equipped with a standard dash-camera feature with the ability to record video in four directions called TeslaCam. Additional views have been known to be recorded under specific circumstances, often triggered in impacts, and available to some owners through data requests to Tesla. Prior research into TeslaCam either did not fully explore all known camera views across multiple vehicles or the metadata associated with genuine copies of TeslaCam video. Testing and analysis of real-world crashes revealed a reliable methodology to conducting photogrammetry analysis utilizing the front, rear, and side cameras found on Tesla Model 3 and Model Y vehicles, how to verify the likelihood of any copy of TeslaCam being a genuine original video discovered during the course of an investigation, and how to examine ever changing video properties as new software becomes available for the vehicles. Moving and stationary Tesla vehicles captured frames of GPS instrumented vehicles as they traveled near the Telsa. Reverse projection photogrammetry projects successfully measured speed within 2 kph of GPS instrumentation and identified expected camera properties.
