In the case of high-speed moving objects, the image should be collected by a progressive scan camera or a field acquisition method using an interlaced camera.
The line array camera is suitable for the large size of the target object, or small defects, such as: Printing quality inspection, PCB testing, cloth or cotton detection, grain (grain, fruit, etc.) detect
Today, let's talk about how to develop a camera on the Android platform! Here we will talk about calling the System camera. 1. Obtain the surfaceview object [html] surfaceView = (SurfaceView) findViewById (R. id. g3_server_preview); surfaceView = (SurfaceView) findViewById (R. id. g3_server_preview); 2. Declare some callback Methods later to enable the camera and

Build a Camera Application
Some developers may want to customize the Camera user interface in their applications, or provide some special functions. Creating a custom Activity requires more code than using Intent, but it can provide a better user experience.
Follow these steps to create a customized Camera interface:
1. Check and access

Camera Control for Android Development
Currently, mobile phones generally provide camera functions. Some cameras even support more than 13 million pixels, and some even support independent focus and optical zoom. These functions are available only for slrs, even some mobile phones can be directly advertised to capture stars. It can be said that mobile phones have become professional digital cameras. To make

Some netizens wrote to me hoping to understand the specific derivation process from the world space to the camera space transformation matrix in the fixed assembly line. In fact, I have explained how to use the camera transform as an example of using the basic theory in vector ry 6, but it may not be specific enough. In this art
In Android 5.0 (SDK 21), Google uses Camera2 instead of the camera interface.
