What sensors are needed for automatic parking technology?

Ultrasonic sensor of Pacific automobile network. The ability of self-driving will eventually surpass that of human drivers, and the ability and way of self-driving cars to obtain information can realize superhuman perception through more sensors. It is actually a self-defeating martial arts and self-restraint to use simulated human driving to shield the perception of these more dimensional information.
