Measure Log Along Polyline
In this tutorial you can learn how to measure log along polyline.
Compared to regular log (containing all incoming signals/sensors information), this type of log also contains info about reference (real) path with binded timestamps. Having this info gives us more opportunities to debug problems and tune navigation parameters.
Download and install Navigine application in the Google Play Store and install it following the instructions from the Getting Started page.
For start using Navigine app you should:
- Go to ”Add beacons” and click on “measure log along polyline” button in the top left corner.
-
After that you will see a menu that you will use to specify a polyline (a route that you will take while recording log).
-
A polyline is presented by a set of points that you will have to specify in this menu. Note, that starting point will be created at the position of cursor upon clicking on bottom right button. Other points are specified by moving cursor to proper place and clicking “Add point”. After last point is specified, you click “Finish”. If you made some mistakes and want to cancel this line, simply click on bottom right button again.
-
Now you have to go to start point. At that point you click “Start Measuring” and start walking along route and at the same time. Our processing algorithms assume constant velocity motion, so please don’t make stops during log recording and try to keep approximately same speed during walking.
- Each time you pass another checkpoint (vertex), you click “Checkpoint” in the application, so that application can bind your current position to current time label. All passed points and sections will be marked with green color.
- After last checkpoint you will be shown the name of resulting log file and you can click “Finish”.
- To share the log-file go to Profile tab -> “Wheel” (top right corner) -> Log management -> Tap on file.
