Everyone has a digital camera.
It's pretty common knowledge a digital image is a flat array of pixels.
Each pixel has a combination of red, green and blue to recreate the captured color at that point.
Now imagine that in addition to color, you could capture the location of each pixel in space.
Now the pixels aren't flat anymore.
Collectively they are a "cloud" of points which represent the scene in three dimensions.
LiDAR produces this "point cloud" and is basically just a digital 3D camera.
