Alasdair Allan, space hacker and author of Learning iPhone Programming and an upcoming book on iOS 4 sensor programming, has a new video out that covers the open source OpenCV framework as well as the sensors in the iPhone:
This video guides you through developing applications for the iPhone and iPad platforms that make use of the onboard sensors: the three-axis accelerometer, the magnetometer (digital compass), the gyroscope, the camera and the global positioning system. You’ll learn how to make use of these onboard sensors and combine them to build augmented reality applications. This will give you the background to building your own applications independently using the hottest location-aware technology yet for any mobile platforms.
