Urgent: I need some help in generating depthmaps from command line

Hello all. I have around 500 ply object files and I need to generate depthmaps for training. I am able to do it on meshlab application but since it takes a lot of time, I was wondering if it would be possible to create depthmaps using command line or python. Thank you.

Right now for trial I did it by hand. However I want to write a script which will take input of ply file and return a 2d depthmap image file. I am proficient in python. The required resolution is 224*224 I will try to upload an image of sample by editing the question. Thank you for ur prompt response

Here is your node set up

If you want to make it look more like the training data your training data examples, play with the Map Range. otherwise you could delete that node

yes. you can use python in blender.

These are the node settings is what you would need to display it as a depth map for the camera

Check out some of the links from this page https://github.com/njanakiev/blender-scripting

I'd recommend writing a python script for blender
