In the comparison of ToF, binocular and structured light,the biggest advantage of ToF is distance measurement. Its depth calculation accuracy does not change with distance. It can basically be maintained at the centimeter level. In scenes that include a large range of motion, The applicability of ToF sensor is very high.
Before 2010, ToF technology was mostly used in scientific research fields such as "cosmic measurement" and "high precision microscope". In recent years, with the significant improvement in the performance of light-emitting components, the demand for 3D applications has expanded and the demand for 2D images has also gradually increased to 3D images in the context of the rise of autonomous driving, VR/AR, robotics, and Internet of Things industries. It has also driven the market development of ToF sensors.
At present,Application with the highest ToF matching include: ranging and perception of the driving environment in autonomous driving, monitoring of human-machine collaborative safety distance in the industrial field, machine vision, volume and weight calculation in the logistics industry, robot navigation, etc.These application areas make full use of the advantages of ToF sensors in accurate positioning and distance measurement.
