How to create calib file for object detetion with using images?

I’m looking for a method of INT8 quantization using trtexec.
The model targeted for quantization is an object detection model, such as YOLO at the following URL.
I’m thinking of creating a dataset for calibration, but how do I create a calibration file?
Can this be achieved using trtexec? If that doesn’t happen, is there another way?
