What is a Lidar Camera?
A Lidar camera is a device that uses laser light to create high-resolution 3D images of its surroundings. It works by emitting laser pulses and measuring the time-of-flight and wavelength of the reflected signals. This information is then used to create a detailed 3D point cloud, which can be used to generate accurate models of the environment.
How Does a Lidar Camera Work?
The working principle of a Lidar camera is based on the time-of-flight method. Here’s a simplified explanation of the process:
- The Lidar camera emits laser pulses towards the target area.
- The laser pulses bounce back from the objects in the environment and return to the camera.
- The camera measures the time-of-flight of the reflected signals, which is the time it takes for the laser pulse to travel from the camera to the object and back.
- The camera also measures the wavelength of the reflected signals, which provides information about the distance and reflectivity of the objects.
- The measured data is then used to create a 3D point cloud, which is a collection of data points in 3D space.
