摘要： A calibration unit 60 acquires detection signals each generated by one of a plurality of sensors in a sensor unit 40 and indicating detection results of a calibration target. A state detection unit 61 detects a state of the calibration target by using the detection signals. A time difference correction amount setting unit 65 calculates a time difference between the detection signals each generated by one of the sensors of the sensor unit 40 by using state detection results of the calibration target obtained by the state detection unit 61, and sets a time difference correction amount on the basis of a calculation result. Temporal misalignment between pieces of information acquired by the plurality of sensors of the sensor unit 40 can be corrected on the basis of the time difference correction amount set by the time difference correction amount setting unit 65.

摘要： The present technology relates to an information processing apparatus, an information processing method, a program, a mobile-object control apparatus, and a mobile object that make it possible to appropriately set the accuracy in detecting an object.
An information processing apparatus includes a first object detector that performs an object detection on the basis of first sensor data from a first sensor; a second object detector that performs an object detection on the basis of second sensor data from a second sensor that differs in type from the first sensor; a tracking section that predicts a state of a target object that is a tracking target, on the basis of a result of the object detection performed on the basis of the first sensor data, and on the basis of a result of the object detection performed on the basis of the second sensor data; and a detection accuracy controller that sets a high-resolution range on the basis of the state of the target object that is predicted on the basis of the result of the object detection performed on the basis of the first sensor data, and on the basis of the result of the object detection performed on the basis of the second sensor data, the high-resolution range being a range in which an object detection is performed with a higher degree of accuracy than in a range other than the high-resolution range. The present technology is applicable to, for example, a system used to track a target object around a vehicle.

摘要： The present technology relates to an information processing apparatus, an information processing method, and a program that allow a sensing time of a sensor to be easily and accurately determined. An information processing apparatus includes a control circuit that outputs a control signal for controlling a sensing timing of a sensor, a counter that updates a counter value in a predetermined cycle, and an addition circuit that adds, to sensor data output from the sensor, sensing time information including a first counter value, a second counter value, and a GNSS (Global Navigation Satellite System) time in a GNSS. The first counter value is obtained when the control signal is output from the control circuit, and the second counter value is obtained when a pulse signal synchronous with the GNSS time is output from a GNSS receiver. The present technology can be applied to, for example, a vehicle-mounted camera.
