[Help] calculate size of an object with camera

I need a developer to create an extension to calculate the size of objects using the device’s camera.
The solution can be simple, width and height of the object.
The simplest way I could find was using Python with OpenCV, maybe deploying the project and sending the image via post is a solution

You can send me a DM with your budget

I can make this app using python as backend which can be hosted on cloud as backend server
It will cost 5000 INR
