LAPD: Laser-Assisted Photography Detection


LAPD (at is my research project to detect hidden cameras with just a smartphone. We created a smartphone app on Android that emits laser signals from the time-of-flight (ToF) sensor on certain smartphones, and uses computer vision and machine learning techniques to locate the unique reflections from hidden cameras.

Most of the information about LAPD can be found on my research page. However, I thought it might be interesting to describe some of the interesting quirks of the project.
