From the analysis of the articles shared by DOMI before, 3D camera imaging solutions have their own advantages and disadvantages, but from the perspective of practical application scenarios, in the non-autonomous field, structured light, especially speckle structured light, is the most widely used. Because in terms of accuracy, resolution, and the scope of application scenarios, tof sensor is a better choice. Moreover, for structured light that is easily disturbed by ambient light, especially the influence of sunlight, the tof sensor does not need to worry about the problem of ambient light.
Comparison of structured light and tof sensor
In contrast, structured light technology is more suitable for static scenes. The tof sensor solution has lower noise and higher FPS at long distances, so it is more suitable for dynamic scenes.
At present, structured light technology is mainly used in unlocking and secure payment, and its application distance is limited. The tof sensor is more widely used, mainly used for rear-mounted photography of smartphones, and has a certain role in AR, VR and other fields (including 3D photography, somatosensory games, etc).
