ToF camera, that is, the sensor emits modulated near-infrared light, which reflects after encountering an object. The sensor calculates the time difference or phase difference between light emission and reflection to convert the distance of the captured scene to generate depth information.Compared with the other two solutions of 3D depth vision (structured light and binocular stereo imaging technology, the ToF sensor has significant advantages in practical applications. For example: post-processing is not required when calculating the depth of field after the picture is captured, which can avoid delays and improve performance. Save the cost associated with the use of a powerful post-processing system; ToF sensor has a large range of flexibility, and in most cases, it only needs to change the intensity of the light source, the optical field of view, and the pulse frequency of the transmitter; The multiple advantages of small size, fast response speed and high recognition accuracy make ToF sensor application field increasingly becoming the preferred technical solution for 3D vision. At present, ToF sensor technology has a wide range of applications, including:
Consumer electronics: virtual reality, face recognition, somatosensory interaction, etc.
New retail: gesture recognition, passenger flow statistics, behavior recognition, etc.
Intelligent security: face recognition, behavior analysis, etc.
Industrial automation: automatic obstacle avoidance, distance measurement, perception positioning, etc.
Medical Electronics: Augmented Reality, Remote Interaction, etc.
Automotive electronics: assisted driving, face recognition, gesture recognition, etc.
