In the smartphone market, ToF camera solution has frequently appeared in many smartphone products, and has quickly become the mainstream solution in the field of 3D vision. In fact, major application markets are showing increasing demand for 3D depth vision technologies such as ToF cameras, among which machine vision applications are the most common.
In some machine vision applications, such as image recognition, image detection, visual localization, object measurement, object sorting, etc., creating 3D images of objects is essential. Due to various advantages, ToF camera is considered to have the potential to usher in a wide range of applications in this regard.
In the consumer sector, robot vacuums are increasingly equipped with machine vision capabilities. Current mainstream implementation method is to configure ToF camera, by adding ToF camera for auxiliary positioning, so that the robot vacuum can continuously track the image during the moving process, and estimate the relative position change between the camera posture and the object, so as to achieve obstacle avoidance. Before the rise of visual navigation technology, ToF cameras occupied an important position.
ToF camera solution meets the needs of machine vision and can better protect privacy. In addition, when the indoor lights are turned off or the curtains are tightly closed, the effect of the visible light camera is greatly reduced, and the ToF camera is more advantageous because of the self-illumination principle.
