xiaohu replied to xiaohu's discussion Stereo Vision sensor module for UAV---What do you want??
"Thanks for your reply.

If the functionality of obstacle avoidance is based on putting a constraint on the maximum flying speed of Quadcopter, will you accept this condition?"

xiaohu replied to Bogdan's discussion Yaw drift with MadgwickAHRS
"if you have the mathematical basis about matrix theory and statistics, you can google "kalman filter UNC" which may help you. Otherwise, if you don't wanna go deep into mathematics, maybe MadgwickAHRS is good enough for you to build a Quadcopter.…"

xiaohu replied to Ankur Mohan's discussion Using the MPU6050 for Quadcopter Orientation Control
"Nice, but maybe you should try those two fusion methods by adding some linear acceleration to see the comparisons.
I do think that there may be a threshold for filtering large linear acceleration mixed measurements for MPU6050, also you can do this…"

Hi, all:Our team is working on some kind of stereo vision system for drones and we have already made some progress. However, we would like to know from you:What kind of functionality you want from this module, like vision-based hovering indoor or…

xiaohu replied to Bogdan's discussion Yaw drift with MadgwickAHRS
"You have only gyro and acc. Acc is going to be used for compensating the drifts along roll and pitch axis, while for yaw axis, there is no information available for compensation. No doubt it will show a drift since actually you are just use gyro-z…"
