Question about animating other 3D charactor

[adf1178]

Thanks for your code!

When I run your code, I found that the princpt is calculated based on the bounding box. When I use the focal and princpt to animate other model such as using IDOL, their default prinpt is the middle of the image. Therefore, using the princpt in the inference.py to animate other characters will lead to different video size. How can I modify it?

Thank you!

A further comment:

I try to animation the character using the size of bbox as princpt. However, I find a problem.

            yolo_bbox_xywh = np.zeros((4))
            yolo_bbox_xywh[0] = yolo_bbox[bbox_id][0]
            yolo_bbox_xywh[1] = yolo_bbox[bbox_id][1]
            yolo_bbox_xywh[2] = abs(yolo_bbox[bbox_id][2] - yolo_bbox[bbox_id][0])
            yolo_bbox_xywh[3] = abs(yolo_bbox[bbox_id][3] - yolo_bbox[bbox_id][1])
            
            # xywh
            bbox = process_bbox(bbox=yolo_bbox_xywh, 
                                img_width=original_img_width, 
                                img_height=original_img_height, 
                                input_img_shape=cfg.model.input_img_shape, 
                                ratio=getattr(cfg.data, "bbox_ratio", 1.25))  

Here, the yolo bbox is scaled. If I use original yolo bbox, the animated human will be cropped. If I use processed_bbox, the animated character will be scaled, too.
