为实现通用便携的印刷网点检测，提出基于移动平台的印刷网点检测技术。印刷网点检测，先进行图像分割，再获取网点中心，计算网线角度等。为在基于Android操作系统的智能平台上实现印刷网点检测，采用Android-JNI技术，该技术的核心是NDK编译，先配置NDK编译环境，再编辑C/C++源文件和mk文件，最后通过NDK编译，将C/C++编辑的图像处理程序编译为Android工程可以调用的库文件。实验验证，本系统可在运行Android系统的移动平台上实现网点图像的自动阈值分割。

In order to achieve portable detection device for print, this paper indicates a dot detection technology based on mobile platform. Dot detection includes image segmentation, obtaining center of dot, computing dot angle etc. In the mobile platform with Android OS, it is realizing dot detection by using android-JNI technology. The core of Android-JNI is NDK compiler which consists of 3 steps. It configures first the NDK compiler environment, and then edits the C/CPP source file and the mk file, finally, through the NDK compiler, converts the image processing program editing by C/C++language to the library file that Android project can call. Experimental results show that this system can realize the automatic threshold image segmentation in the mobile platform with Android OS.
