Sensor fusion: the importance of time

Sampling rates All sensors sample at an independent rate. Stated another way, different sensors generate a signal at different times and at different intervals. Some sensors such as scanners create a signal of a specific duration. Figure 1 shows conceptual the relationship between the sample times of five different sensors. The signals from the sensors […]

The end of systems

In the Industrial Age, machines were mechanical creations. Force of wheels, belts, cogs, levers and pressure valves controlled the action and response of machines. There were mechanical decision makers of sort, with check safety valves, throttles and regulators, but most advanced control was in the hands of a human operator who monitored pressure and spring […]

Sensor fusion: the importance of position and attitude

System topology The following figure shows an imaging sensor and its dependencies on a rotational encoder, a global positioning system (GPS) and an inertial measurement unit (IMU). The imaging sensor has an internal coordinate system. The imaging sensor is attached to a rotating arm. A rotational encoder provides an observation of the arm’s position. We […]

Fundamental theory of sensor fusion

The objective of sensor fusion is to determine that the data from two or more sensors correspond to the same phenomenon. A sensor is an electromechanical device that translates the energy of a physical phenomenon into a signal. Examples of sensors are digital thermometers and video cameras. An actuator is an electromechanical device that translates […]
