Difference between tof and lidar

Different principles, different applications.

1, the principle is different: TOF is to send a beam of light to the target object, detect the returned light signal, calculate the light emission and reflection time difference or phase difference to calculate the target object distance. LIDAR is to use the laser to emit a laser beam, irradiate the target object, detect the reflected back laser signal, calculate the distance, direction, speed, attitude and other data information of the target object.

2, the application of different: TOF technology, high precision, good stability, strong anti-interference ability, used in face recognition, unmanned, three-dimensional vision and other fields. Lidar is used in unmanned vehicles, robotics, logistics, mapping and other fields.
