How 360 degree camera works?

 As today the technology is upgraded from a bit resolution camera to high resolution camera but sometimes we thought that how the 360 degree camera works in car the answer is seen to be tipical but it is clear as though.

There are 2 lenses in the camera each of which were of 180 degree wide resolution,both the lenses were play very important role.these lenses make a sphere of the surrounding by joining the two pictures of each side and show some of the touches which were set as default by company for example:car structure from above the ground level which is set as default by the company,these camera helps us to park our car in tight parking area.

Thank you
