Sügavuskaamerad, also known as depth cameras or 3D cameras, are devices that capture information about the distance of objects in a scene. Unlike traditional cameras that only record two-dimensional color or grayscale images, depth cameras can determine the depth of each pixel, creating a depth map or a point cloud. This additional depth information allows for a more complete understanding of the scene's geometry.

There are several technologies used to implement depth cameras. Time-of-Flight (ToF) sensors emit light, usually infrared, and measure the time it takes for the light to reflect off objects and return to the sensor. Structured light cameras project a pattern of light onto the scene and analyze how the pattern is distorted by the objects' surfaces. Stereoscopic vision systems use two or more cameras to triangulate the position of objects based on parallax, similar to how human eyes perceive depth.

The applications of depth cameras are diverse and continue to expand. They are integral to augmented reality (AR) and virtual reality (VR) systems, enabling realistic interactions with virtual objects and environments. In robotics, depth cameras provide crucial data for navigation, object recognition, and manipulation. They are also used in gesture recognition for human-computer interaction, 3D scanning and modeling, and in the automotive industry for advanced driver-assistance systems (ADAS) and autonomous driving. Furthermore, they find use in medical imaging, surveillance, and in creating immersive photography and videography.
