Welcome to the Potholes wiki!

Realtime Pothole Detection

Idea

• Mobile phone centric detection
• With accelerometer and gyroscope data
• 50Hz, 20ms sensor refresh rate

Architecture

Data Acquisition

Format: Time-stamp, Accel X, Accel y, Accel Z, Gyro X, Gyro y, Gyro z

Data modeling

Accelerometer data plot Raw data plot, Mean, Standard Deviation

Gyroscope data plot Raw data plot, Mean, Standard Deviation

Confusion matrix

Export model from MATLAB to C code

Export trained model to C code using MATLAB coder

Import model C code in Android Studio

Use JNI to access the svmPredict() function.

TODO

• Calibration for running the trained model based on the initial orientation of the smartphone.
• Calibration shall provide a rotation matrix for coordinate transformation between the orientation used while obtaining the data and the orientation of the phone during the detection.
