How to decide camera parameters specifically for edge detection?

Hello eveyone, I have an image of a car door from which I found a trajectory from specific edges of the car door. Let me expain the detail about my project.

Project: Finding the edges of a door and used those edges as a trajectory for a sensor that checks edges for Gap/Flush.

Principle: I used Savitzky Golay, Edge Linking and Line Segment Fitting (https://www.peterkovesi.com/matlabfns/#step2line).

Method I used: Image Analyst's Savitzky filter smoothening at three diffrent thresholds, obtain three images and blend them. The output is again processed to Edge linking and line segmenting program.

Now I have to decide on the camera sensor parameters. I dont know how to decide a camera SENSOR for this specific purpose Your suggestions will be very valuble!

Thanks
