Since the development of image sensors, from 2D to 3D has become the general trend, especially in the current widespread use of smart phones, consumers' continuous demand for cameras makes manufacturers more active in the field of 3D sensing.
At present, 3D sensing technology mainly focuses on structured light sensing technology and tof sensor technology. Structured light technology is suitable for scenes with short distances and high accuracy, while tof sensor technology has a wider application range and is available. For games, driving, AR, 3D modeling, etc.
In 2017, Apple released the iPhone X and officially introduced 3D sensing technology into the mobile phone market with structured light sensing technology. Subsequently, various Android manufacturers have also begun to introduce 3D sensing technology.
In 2018, with the launch of OPPO R17 Pro, the mobile phone camera TOF sensing solution was used in Android phones. Subsequently, the flagship models of manufacturers such as Huawei and Samsung all used tof sensor.
