Sony patents method to align different sensors using a shared object
Sony describes a system that calculates the exact position and angle between two different spatial sensors. It uses a third sensor to measure a calibration object placed in the view of both sensors, allowing the system to determine how the first two sensors relate to each other.
In the filing’s own words
The present technology relates to an information processing apparatus, and information processing method, and a measurement system that enable calibration with high accuracy relating to relative positions/postures of a plurality of sensors that senses spatial information regardless of the type, sensing range, and the like of each sensor. A relative positional relationship between a first sensor and a second sensor is calculated on the basis of third sensor data obtained by a third sensor that measures three-dimensional information regarding a calibration object disposed in at least part of measurement ranges of the first sensor and the second sensor that measure spatial information, and first sensor data and second sensor data that are respectively acquired by the first sensor and the second sensor.
What exactly they claim (claim 1)
1. An information processing apparatus, comprising: a processing unit that calculates a relative positional relationship between a first sensor and a second sensor on a basis of third sensor data, first sensor data, and second sensor data, the third sensor data being obtained by a third sensor that measures three-dimensional information regarding a calibration object disposed in at least part of measurement ranges of the first sensor and the second sensor that measure spatial information, the first sensor data and the second sensor data being respectively acquired by the first sensor and the second sensor.
