Re: sending data to serial terminal of host PC

Hi, I have seen the video on youtube describing the use of open terminal but I am not sure it will be useful for my project. I am trying to do the following. I am acquiring an image with OpenMV cam. fining the blob and getting the centroid of that blob. Now I want to do curve fitting on the line pro...

sending data to serial terminal of host PC

HI,
In OpenMV IDE there is a serial terminal for debugging the code of pyboard. Can the IDE settings be modified, such that this debug data is directly available at serial terminal of host PC?

Re: How to do curve fitting on detected blob

Hi kwagyeman,
Can you suggest any tutorial or document to follow, that can be used to include scipy.optimize.curve_fit for OpenMV environment?

Re: How to do curve fitting on detected blob

Hi kwagyeman,
Thank you for your reply. I used OpenCV (cv2.moments) for centroid calculation and scipy.optimize.curve_fit for curve fitting.
Will I have to write these codes in micropython modules for my application?

Re: How to do curve fitting on detected blob

Hi kwagyeman, Thank you for your reply. I have seen find_blobs api. However my understanding is, it will return the number of blobs and their area (coordinates). But I am supposed to do curve fitting on the detected blobs to calculate sigma of Gaussian profile. Can you suggest me how I will be able ...

How to do curve fitting on detected blob

Hi All, I want to build an application using OpenMV Cam7. In my application I am suppose to find size of the bright object detected by the camera sensor. The bright object will have Gaussian distribution. So in my application I am suppose to measure the centroid of the bright object, fit Gaussian fu...
