Can phones be used as an SLS Camera?

Paranormal investigations have long been a topic of interest, with many individuals seeking to understand and explore the unknown. In recent years, modern mobile phones with LiDAR technology have emerged as a cost-effective and convenient alternative to traditional tools like the Kinect SLS camera for detecting people-shaped objects during paranormal investigations.

The traditional Kinect SLS camera

Paranormal investigators typically think of the Kinect SLS camera for help in detecting people shaped objects on their investigations. Using an infrared light grid, the camera is able to detect even faint movements, allowing paranormal investigators to easily identify potential paranormal activity by identifying unexpected shadows or other changes in the environment. Although a popular tool, the traditional Kinect SLS camera is often bulky, records in a low frame rate and is typically very expensive (often upwards of $500 or more)


What is LiDAR?

LiDAR, or Light Detection and Ranging, uses lasers to measure distances and create detailed 3D maps of the environment. This technology is now available on some modern mobile phones, and it has the potential to revolutionize the field of paranormal investigations.

One of the key benefits of using a mobile phone with LiDAR technology during paranormal investigations is the increased accuracy of the data that is collected. LiDAR technology can produce highly detailed 3D maps of the environment, which can provide a clearer understanding of the location and movement of people-shaped objects. This is especially important in paranormal investigations, where the presence of people-shaped objects is often the focus of the investigation. Given the most people have a phone already, it also means SLS capabilities are accessible to more people, often at a fraction of the price of a traditional SLS camera.



Detecting depth and people without LiDAR

Phones are equipped with other sensors that can detect depth and/or people shaped objects (ie pose detection) even if they don't have a LiDAR sensor. Motion and direction sensors measure acceleration and orientation relative to external sources such as the ground or other objects. This way, phones can track user's movements in three-dimensional space with a great degree of accuracy. Combined, these sensors allow for precise detection of user's position and orientation in any given environment in order to enable immersive applications like augmented reality on the phone. Advanced machine-learning algorithms can also use regular camera frames to detect people shaped objects.



Are phones better than a Kinect SLS camera?

Modern mobile phones are more convenient and cost-effective than traditional paranormal investigation tools like the Kinect SLS camera. They are small and portable, making them easy to carry and use in any location. Additionally, since many people already own a smartphone, there is no need to invest in expensive equipment, making it an accessible option for anyone who is interested in paranormal investigations. Modern mobile phones with LiDAR technology have even more potential to revolutionize the field of paranormal investigations.

GhostTube SLS is the world's leading and most popular app alternative to the traditional SLS camera used by investigators. On LiDAR equipped devices, it uses the advanced depth information provided by the sensor for highly accurate pose detection. On devices without LiDAR, it relies on the numerous cameras and sensors present in most mobile phones for comparable results. GhostTube SLS can also be used on your investigation for FREE, whereas a standalone Kinect SLS camera could cost you hundreds of dollars.
