Do you use the PDR model

[PavelTychinin]

Yes. You can find source code here https://github.com/Navigine/Indoor-Positioning-And-Navigation-Algorithms/tree/master/standalone_algorithms/pedometer

Does the algorithm only use the acceleration data,not gyroscope data？

Gyroscope and magnitometer data can be handled using complementary filter: https://github.com/Navigine/Indoor-Positioning-And-Navigation-Algorithms/tree/master/standalone_algorithms/complementary_filter

You can see the example of using it here: https://github.com/Navigine/Indoor-Positioning-And-Navigation-Algorithms/blob/master/standalone_algorithms/complementary_filter/examples/main.cpp#L157

Do you mean to use complementary filtering to fuse gyroscope and magnetometer data sets to improve the accuracy of PDR?

[fedormex]

Not exactly, I would say: pedometer+ complementary filter forms the PDR algorithm. Pedometer itself allows to detect steps and their length while complementary filter allows to determine direction. So, joining these two components together you can get a PDR trajectory.

OH，I know,you have build the compleat pdr algorithm,what you mean is i just only use the pedometer+ complementary file to perform the pdr alogrithm.Is this ?

[panlongming]

that have the complete pdr algorithm in the file

Yes. If you need to implement a PDR algorithm (building pedestrian trajectory based on sensors) you should use both pedometer and complementary fileter.

Thank you，I get it

I am an algorithm engineer for indoor positioning. Can I add your email address to contact you for further information?

[fedormex]

Yes, sure.

[panlongming]

How should I contact you?
