it would be nice if you also include the method you are using such as algorithm, papers, result, etc. As a student, it would be really help full to learning such stuff

When we run "Main_Stereo_Vision_Prog.py" it gives the above error in stereocalibrate function

SystemError: new style getargs format but argument is not a tuple

how do you substitute the values in the above...What is the equation you are using to get the distance value.

Hi,
When I try to run the main program I got the following error:
AttributeError: module 'cv2' has no attribute 'ximgproc'

Does I need any additional libraries?

How big is his error?

excuse me，
I want to know if This project can only be applied to the detection target as a plane
please tell me,
thanks,
PS: Apologize for my poor English

It is unclear what the versions of dependencies (OpenCV, numpy etc) this successfully works with and have had some issues running out of the box. Can you be more specific on environment configuration and versions please. Thanks

-Processing speed is too slow, I need to make it faster what I should do?
-What is the maximum distance range? I got only 5 meters, Is there any way to get the distance reach about 8 meters??
-Should I input the distance between the two lenses in the code??

I don't understand the concept of Excel file... Can you please elaborate, How and why its needs the Excel file... I'm getting the following error

PS B:\TUHIN\PYTHON PROGRAMS> python '.\10_1 Main_Stereo_Vision_Prog.py' Traceback (most recent call last): File ".\10_1 Main_Stereo_Vision_Prog.py", line 23, in <module> from openpyxl import Workbook # Used for writing data into an Excel file ModuleNotFoundError: No module named 'openpyxl'

Hello,

I would like to know, if this script can measure the distance of any object shown in a stream, no matter where it's located?
If not, what adjustments in the code are necessary?

I plan to use a stereo camera and a pretrained CNN, which detects objects, additionally I want to measure the distance to the detected objects.

Thanks in advance

How do I select a point in 2d image (either from the right camera or the left camera) and get the distance through the stereo vision?

Hi,

May I ask you to explain this line of the code, for which reason you are using those numbers.
Distance= -593.97*average**(3) + 1506.8*average**(2) - 1373.1*average + 522.06

Thanks.
