The gyroscope
Accelerometer
The Magnetometer
The data collection frequency is 100 grz (if three sensors are not able to flow at the same time, it can be reduced).The received data must be recorded in the text document in the form:
TimeStamp
Type of Sensor
- indications of the sensor (x,y,z) but it is already depending on the sensor.The data is recorded through the tab, the CSV file format.In the process of recording the data, you need to record the video in a minimum resolution with the front camera.It is extremely important to put time on the video with accuracy of up to a millisecond.The name of the video file and log file should match and be set in the application interface
The file format is not fundamental.the interface.It consists of the Start button (individual view and location), the input field for the name of the log file (video and csv) and the free zone in which the image is removed from the front camera.It does not necessarily mention the current time, but in the video it should be.After starting and starting the recording, the Start button changes to Stop, which respectively terminates the recording.And it changes again to Start if the application is ready to repeat the next cycle.It is permissible to create not one csv and three - one by one on the sensor, then we add the type of sensor to the name.It is permissible not to write immediately in the file and, for example, in the bd timetable and only at the end of the record to download the results in the files.It is ideal to create files in which all files of one record are grouped.The records are stored on the map, preferably in Download which would be more convenient.It is important that the time in the log file has a minimum resynchron with a video timer.This is very important and critical.The purpose of the project is to record these three sensors.If necessary, I will send the clock to the development time for the disposal, we will discuss it.The development time is not critical.If everything goes well, then the next project will be the connection of the Garmin clock, then Google fit, but it’s according to your wish.Why all this?The project is needed to collect data from the hours for the subsequent training of the ml model.The video is necessary to further decrypt the data and the connection that occurs with the current sensors.We will work through the seafood.The completed project must include:
The building apk (working)
Instructions on how to set the clock and application (if this is not obvious)
A comebacked code on my guitar.
- returned clock (if necessary for development).It is permissible to use third-party projects from the guitar.I do not require copyrights for this code.The version of Android is desirable "more" but if it gets to quickly collect but will work only on some of the old because of the used libraries - it's not a big problem.Ready to clarify questions.by P.S.I have been working as a project manager for more than 15 years in development and quite well-established.I do not intentionally try to write a low-level TZ as my stick node.js, react, etc., so I expect the artist himself to recommend the best way to the result.
