Abstract
Disclosed is a laser radar apparatus. The laser radar apparatus includes: a light transmission unit configured to output a laser pulse by using a light source; a light reception unit configured to receive a reflected laser pulse in connection with the laser pulse; and a controller configured to adjust a repetition rate of the laser pulse of the light source, in which the controller adjusts the repetition rate of the laser pulse based on at least one of reception power, a target distance, a movement speed, a vertical angle, and a radiation angle.
Claims18
A laser radar apparatus, comprising:
- a light transmission unit configured to output a laser pulse by using a light source;
- a light reception unit configured to receive a reflected laser pulse in connection with the laser pulse;
- and
- a controller configured to adjust a repetition rate of the laser pulse of the light source,
- wherein the controller adjusts the repetition rate of the laser pulse based on at least one of reception power, a target distance, a movement speed, a vertical angle, and a radiation angle,
- wherein the controller measures the reception power from the reflected laser pulse, and when the reception power is increased, the controller increases the repetition rate of the laser pulse, and when the reception power is decreased, the controller decreases the repetition rate of the laser pulse.
A laser radar apparatus, comprising:
- a light transmission unit configured to output a laser pulse by using a light source;
- a light reception unit configured to receive a reflected laser pulse in connection with the laser pulse;
- and
- a controller configured to adjust a repetition rate of the laser pulse of the light source,
- wherein the controller adjusts the repetition rate of the laser pulse based on at least one of reception power, a target distance, a movement speed, a vertical angle, and a radiation angle, and
- wherein the controller receives the movement speed of a movement body to which the laser radar apparatus is attached.
A method of acquiring an image of a laser radar apparatus, comprising:
- outputting a laser pulse by using a light source;
- receiving a reflected laser pulse in connection with the laser pulse;
- and
- acquiring an image by using the reflected laser pulse,
- wherein the outputting of the laser pulse includes adjusting a repetition rate of the laser pulse of the light source based on at least one of reception power, a target distance, a movement speed, a vertical angle, and a radiation angle, and
- wherein the adjusting of the laser pulse includes:
- measuring the reception power from the reflected laser pulse;
- and
- when the reception power is larger than a reference power, increasing the repetition rate of the laser pulse, and when the reception power is smaller than the reference power, decreasing the repetition rate of the laser pulse.
