US 10,852,731 B1 · Method and system for calibrating a plurality of detection systems in a vehicle

Abstract

Aspects of the disclosure provide for a method of calibrating a vehicle's plurality of detection systems. To calibrate a first detection system, orientation data is collected using the first detection device when the vehicle faces a first direction and a second direction opposite the first direction. To calibrate a second detection system, data is collected using the second detection device while the vehicle moves in a repeatable pattern near a first object. To calibrate a third detection system, light reflected off a second object is detected using the third detection system as the vehicle is moved towards the second object. To calibrate a fourth detection system, data collected using the second detection system and the fourth detection system is compared. To calibrate a fifth detection system, radar signals reflected off a third object is received using the fifth detection system while the vehicle moves relative to the third object.

Dependent claims

A method of calibrating a plurality of detection systems of a vehicle, the method comprising:

moving the vehicle relative to a first object in a repeatable pattern;
collecting, by one or more computing devices, a plurality of data points using a first detection system of the plurality of detection systems as the vehicle is moved in the repeatable pattern, the plurality of data points corresponding to the first object;
combining, by the one or more computing devices, locations of the plurality of data points to determine an actual location of the first object;
determining, by the one or more computing devices, a first correction for the first detection system by comparing the locations of the plurality of data points to the actual location;
and
operating, by the one or more computing devices, the first detection system using the first correction.
