TOF CAMERA FOR VEHICLE AND METHOD FOR DRIVING THEREOF

摘要

The present invention relates to a top camera for a vehicle and a driving method thereof, which can increase a detection distance by using multiple laser diodes as a light source. The top camera includes: an emitting unit which radiates light to an object; a light-receiving unit which detects a distance with the object based on the light reflected and returning from the object and generates a modulation signal for the modulation of the frequency of the light; and a control unit which controls driving of the emitting unit according to the modulation signal of the emitting unit. The emitting unit includes multiple laser diodes and the control unit determines a driving order of the laser diodes according to the modulation signal of the light-receiving unit to control the driving of the laser diodes and determines current values of the laser diodes according to the modulation signal of the light-receiving unit to control the current values of the driving laser diodes.
