android_cv_lane_detection

Android lane detection app built with openCV ndk

Two kinds of image process method are implemented as two jni calls in MainActiviy.java.

One of them(com.example.wenfahu.lane_droid.MainActivity#process) is a slightly improved implementation of jdorweiler/lane-detection. Details please visit Revisiting Lane Detection using OpenCV.

The other (com.example.wenfahu.lane_droid.MainActivity#processOpt) is a simplied version of the method above. And it turns out to outperform that one.

Build

Prerequisite

• Android Studio 2.1.2
• OpenCV Android SDK 3.1.0
• Android SDK 24
• Android NDK 12.1

Highlight

Check out your sdk paths and replace them in the Android Studio's File/Project Structure/SDKLocation and gradle scripts and jni/Android.mk .

The project is built with ARM NEON support (check it out in jni/Android.mk : "LOCAL_ARM_NEON := true") and tested on an android device with ARM Cortex-A53 chips.
