How does the Three-Axis Gyroscope and accelerometer help the iPhone locate

This article is from:,thank you! In June 8 last year, the Great Apple company released the latest iPhone 4G, which has many hardware upgrades. For gamers, the largest "Three-Axis Gyroscope "! The first time I heard that this "Three-Axis Gyroscope" was a time ago, I occasionally found that Apple players were testing the positioning function of the iPod Touch. For details, see "l

iOS Development-coremotion Framework (accelerometer and gyroscope)

Coremotion is a framework dedicated to motion, which contains two parts of accelerometers and gyroscopes, before iOS4 the accelerometer is the Uiaccelerometer class responsible for collecting data, Now generally use coremotion to deal with the acceleration process, but because Uiaccelerometer is relatively simple, the same people are used. Accelerometer is determined by three axes, the user's most common op

"Reading notes" ios-accelerometer with gyroscope

One, the "filter" of the dataThe raw data obtained directly from the accelerometer is often not used directly, but some disturbing data needs to be removed, a process called "filtering". The word "filter" is derived from the process of radio signal processing in radio technology. In fact they are the same from the mathematical point of view, they are some kind of sampling signal, this "filtering" process is very complex, to achieve "filter" by Fourier

Sensor aggregation, including gyroscope, accelerator, and magnetic Meter

designed to measure the rotating motion of a device. Better at the movements of devices. However, the location of the device cannot be determined.The advantage of a accelerometer is to measure the force of a device. Better at the movement of devices than external reference objects (such as the ground. However, it is not accurate to measure the placement posture of the device relative to the ground.The strength of a magnetic meter lies in positioning

Gyro, accelerometer, magnetometer and other sensors summary (turn)

Transfer from gyroscope is an internal gyroscope, whose axis is always parallel to the initial direction due to the gyro effect, so that the actual direction can be calculated by deviations from the initial direction. The gyroscope in the cell phone is actually a very sophisticated chip with ultra-tiny tops

Cell phone's coordinate chart The Core Motion Motion Manager lets you specify how often (in seconds) to receive updates from the accelerometer and gyroscope, and lets you specify a handler block directly (handle block), which executes the handler block whenever the update is ready. The actual acceleration is broken down into two parts in core motion: Gravity and Useracceleration. Gravity represents gr
