xtion sensor

Remember when reading Xtion Pro live depth data and color data, the main use is directly Read NI class. Using this direct method is more troublesome, but also to write a special read program, call NI's function. Now the OPENCV2 integrates the Openni, which can read depth data and color data directly using Videocapture. In contrast, there may be some features that are not so complete.So how to read Openni directly with OpenCV? The following steps are m

Android development: Android device sensor Development Summary, android Sensor In this article, I will share with you how to develop Android device sensors. Please indicate the author xiong_it and link: http://blog.csdn.net/xiong_it/article/details/45917009 Android sensor development process Public class sens?ti=extends Activity implements SensorEventListener {pr

Android Orientation Sensor (Direction Sensor) details and applications, androidorientation I. Preface This blog is my first article on "Android advanced". It has been around for more than four months since I started Android, and I have some experiences, I can also do something on my own. Thanks to the android development tips of our company and the omnipotent help and advice from Hongyang. This series o

The sensor is a detection device that can feel the information being measured, and can transform the detected and sensed information into an electrical signal or other required form of information output according to a certain law.There are many sensors (physical devices) built into the Android operating system that can detect, perceive, and communicate the signals and physical conditions of the outside world to other devices.For example, some games o

ObjectiveAndroid provides support for device sensors, and as long as the Android device's hardware provides these sensors, Android apps can access the device's external conditions through sensors, including the phone's running status, the current orientation, and so on. The Android system also provides drivers to manage these sensor hardware, which can be used by listeners to monitor changes in the external environment perceived by the

The instructor of the fetc project proposed a new requirement. He wanted to show the user's current movement direction in the game map. If he used GPS, it was obviously unreliable, so he thought of the powerful Android sensor... Many mobile devices have built-in sensors. Android abstracts these sensors through the sensor and sensormanager classes, and these sensors can be used by Android devices. 1.

Android --- 57 --- sensor, android Sensor The Android system provides support for sensors.Developing an application sensor is simple. You only need to register a listener for the specified listener. Steps:1. Call the getSystemService (Context. SENSOR_SERVICE) method of Context to obtain the SensorManager object. The SensorManager object represents the system's

Android action sensor and android Sensor Android motion sensor The Android platform supports some sensors used to monitor device movements (five such sensors ). Two of them are pure hardware sensors. The other three (Gravity Sensors, linear acceleration sensors, and Rotation Vector Sensors) may be hardware sensors or software sensors. For example, in some Android

Well, thanks to the recent development requirements for smart hardware, so the recent days to share the blog is roughly linked to intelligent hardware, like a piece of Bluetooth sharing, I believe that many readers have seen, then today I bring you the knowledge of the Android sensor introduction and use of methods, for the use of sensors , different versions of the Android phone may have larger hardware differences, but same, this article will be thr

This time we have studied the development of Android sensors, previously introduced, tween use, so we can combine sensors with tween animation, develop a simple compass.First of all, introduce the sensor knowledge,in the the use of sensors in Android applications depends on the Android.hardware.SensorEventListener interface. This interface allows you to monitor various events of the sensor. The code for th

Android open-source project Sensors The android open-source project (aosp) provides three software-based mobile sensors: gravity sensor, linear acceleration sensor, and rotation vector sensor. These three sensors are updated in android4.0 and both use Gyroscope (except for other sensors) to improve stability and performance. If you want to try these sensors, you

In general, getting the location information of the phone in the Android system has the Type_orientation constant in the API, which can be obtained as the accelerometer sensor Sm.getdefaultsensor (sensor.type_ ORIENTATION); However, we do so in the latest version of the SDK will see this sentence: "Type_orientation this constant is deprecated. Use Sensormanager.getorientation () instead. "That way also expires, not recommended!" Google recommends that

My Android advanced tour ------> Android uses Sensor (Sensor) to implement the level function. The level here refers to a more traditional bubble level, filled with liquid in a transparent disc, with a bubble in the liquid. When one end is tilted, this bubble will float at one end.The first parameter returned by the Direction sensor is used to implement a compas

In this lesson, we will learn the wirelessly light sensor, please bypass this article.The Android system has a feature that automatically adjusts the brightness of the screen. It detects the light intensity of the environment around the phone and adjusts the brightness of the phone's screen accordingly to ensure that the screen can be seen clearly, whether in strong or weak light.Said too much theory is a bit virtual, here Direct combat practical ligh
