I am testing using code from deepstream C/C++ tutorial. However, I would like to get output about the detected bounding box, but it is not being output. Please tell me how I can print the bounding box value through the basic deepstream-app -c deepstream_app_config.txt command.
The method I found is that you need to save it through kitti-output-dir to know the bounding box. It is as follows: Please check if it is correct.

write_kitti_output(AppCtx * appCtx, NvDsBatchMeta * batch_meta){
...
for (NvDsMetaList * l_frame = batch_meta->frame_meta_list; l_frame != NULL;
l_frame = l_frame->next) {
NvDsFrameMeta *frame_meta = (NvDsFrameMeta *) l_frame->data;
guint stream_id = frame_meta->pad_index;
g_snprintf (bbox_file, sizeof (bbox_file) - 1,
"%s/%02u_%03u_%06lu.txt", appCtx->config.bbox_dir_path,
appCtx->index, stream_id, (gulong) frame_meta->frame_num);
bbox_params_dump_file = fopen (bbox_file, "w");
if (!bbox_params_dump_file)
continue;
for (NvDsMetaList * l_obj = frame_meta->obj_meta_list; l_obj != NULL;
l_obj = l_obj->next) {
NvDsObjectMeta *obj = (NvDsObjectMeta *) l_obj->data;
float left = obj->rect_params.left;
float top = obj->rect_params.top;
float right = left + obj->rect_params.width;
float bottom = top + obj->rect_params.height;
// Here confidence stores detection confidence, since dump gie output
// is before tracker plugin
float confidence = obj->confidence;
fprintf (bbox_params_dump_file,
"%s 0.0 0 0.0 %f %f %f %f 0.0 0.0 0.0 0.0 0.0 0.0 0.0 %f\n",
obj->obj_label, left, top, right, bottom, confidence);
}
fclose (bbox_params_dump_file);
....
How can I change the code above to know the bounding box value?
Please give advice to experts.
