Abstract
An altitude measuring method of an unmanned aerial robot is provided. The robot adjusts a level of the unmanned aerial robot so that the robot is at a horizontal state with respect the ground to measure the altitude. The robot generates a plurality of laser beams to the ground, and photographs the ground through the camera. The robot calculates a vertical distance from the ground to the robot based on the photographed image of the ground and the plurality of laser beams.
Claims20
A height measuring method of a robot, comprising:
- adjusting the robot to be level with a surface;
- providing, by the robot, a plurality of laser beam spots on the surface;
- capturing, by a camera of the robot, an image of the surface;
- and
- determining, by the robot, a vertical distance from the surface to the robot based on the captured image and the plurality of laser beam spots on the surface,
- wherein the vertical distance is determined based on a horizontal surface distance from a position of the robot on the surface to a first end point of the image and a specific angle,
- wherein the specific angle is an angle between the vertical distance and the surface distance between the robot and the first end point of the image, and
- wherein the surface distance is determined based on a reference distance.
A robot for determining a height, the robot comprising:
- a main body;
- a camera provided at the main body;
- a plurality of light sources for generating a plurality of laser beams;
- at least one motor;
- at least one propeller connected to each of the at least one motor;
- and
- a processor electrically connected to the at least one motor to control the at least one motor,
- wherein the processor is configured to:
- adjust the robot to be level with a surface;
- provide, on the surface, a plurality of laser beam spots based on the plurality of light sources;
- capture, by the camera, an image of the surface;
- and
- determine a vertical distance from the surface to the robot based on the captured image of the surface and the plurality of laser beam spots,
- wherein the vertical distance is determined based on a horizontal surface distance from a position of the robot on the surface to a first end point of the image and a specific angle,
- wherein the specific angle is an angle between the vertical distance and the surface distance between the robot and the first end point of the image, and
- wherein the surface distance is determined based on a reference distance.
