Claim 7:
8. A system for calibrating sensors, the sensors including a light detection and ranging (LIDAR) sensor, a thermal sensor, and an image sensor, the system comprising:
a calibration device comprising:
a first layer comprising copper;
a second layer comprising solder material, the second layer positioned on a top surface of the first layer; and
a third layer comprising a silkscreen material, the third layer positioned on a top surface of the second layer,
the third layer partially covering the top surface of the second layer,
a side of the third layer aligning along a horizontal axis with a side of the first layer,
the second layer extending, along the horizontal axis, beyond the side of the first layer and the side of the third layer; and

a processor configured to perform sensor calibration by:
determining, based on first sensor data received from a first one of the sensors, a location of the side of the third layer of the calibration device,
determining, based on second sensor data received from a second one of the sensors, a location of the side of the first layer of the calibration device, and
determining that the first one of the sensors and the second one of the sensors are calibrated if the location of the side of the third layer and the location of the first layer are determined to be aligned along the horizontal axis.
