Future?

This is just a feature request to add/support a new NvOSD_PolygonParams so we can create our own Polygons for custom trigger areas and OSD display… by adding the new type to the display meta

typedef struct NvDsDisplayMeta {
  ...
 /** Holds the number of polygons described. */
  guint num_polygons;
  /** Holds an array of positional parameters for polygons.
   Used to overlay borders or semi-transparent polygons, */
  NvOSD_PolygonParams polygon_params[MAX_ELEMENTS_IN_DISPLAY_META];
  ...

} NvDsDisplayMeta;

Thanks,
Robert.

Hi,
We already have line Metadata that can be used to achieve polygon setting or drawing.

That’s not the same though… how would you fill/shade the area inside such lines?

Blending for ROI based like polygon not supported in current OSD,
please wait for upcoming release, we will have NvOSD_PolygonParams support.
