Hi all,
Some context of the project I'm working on
To give some context to my question, let me give some information about the project we are developing.
We are developing a device that will be used in the medical/surgery market and our main need is to have an IMU that gives us relative rotation (we have a calibration routine for setting the reference measurement) information in quaternions.
After looking at the Bosch portfolio, we realized that the best option would be the BNO055, but because it's going out of stock in most of the suppliers we are considering using the BHI260AB.
The question
As far as I know, BNO055 runs internally the BSX3 full library, while the BHI260AB the BSX4 full library.
I'd like to know if there's a difference in the final output accuracy of the sensor fusion between these two chips used in IMU mode.
The sensor fusion accuracy is specified for the BHI260AB, but I couldn't find the same information for the BNO055. In the case of the BHI260AB:
BHI260AB Sensor fusion performance:
– Static accuracy (head., pitch, roll): 2, 2, 2 degrees
– Dynamic accuracy (head., pitch, roll): 7, 2, 2 degrees
As I mentioned before, I've seen in a post that there's no difference in the accuracy of the sensor fusion between BSX3 full and BSX4 full. But, since BNO055 and BHI260AB have some differences in the characteristics of the sensors, that may imply that the final fusion output accuracy is also different.
Thanks
