The LiDAR sensor of the iPhone and iPad Pro serves to enhance photography, but also to create maps depth of our environment. Now, a study from the University of Singapore claims that hidden cameras can be detected with iPhone LiDAR and other smartphones. It would be necessary for the system created by the researchers to land on the App Store in the form of an app.

Uncover hidden cameras with the iPhone’s LiDAR

Finding hidden cameras in Airbnb accommodations is not strange. In fact, it is so frequent that there is a market for devices to detect them , especially in Asia. Perhaps for this reason, a group of researchers from Singapore are responsible for having created a system for detecting hidden cameras with a smartphone .

On the internet you can find everyday objects such as a bottle of water with an integrated hidden camera.

The system created, baptized as LAPD, detects suspicious reflections in everyday objects. To do this, combines variables such as distance, intensity or depth , applying a deep learning filter that collectively detects a hidden camera. In the words of the researchers:

We propose LAPD, a new hidden camera detection system that uses ToF sensors in smartphones. We created LAPD as a smartphone app that emits laser signals from the ToF sensor and uses computer vision and machine learning to locate reflections from hidden cameras. The reliability of this system in experiments is 88, 9% , compared to a 16, 7% false positives. Professional hidden camera detectors like the K 18 get a score of 62, 3% positive and a 26, 9% false positives. The advantage of the LAPD system is clear.

Currently, iPhones 13 Pro, iPhone 12 Pro Max , iPhone 13 Pro , iPhone 13 Pro Max, iPad Pro 2020 Y iPad Pro 2021 are Apple devices that have a LiDAR sensor. Now it only remains for the researchers or any other developer to use this knowledge to create an app commercial.
