BKE_uvproject_camera_info()

struct ProjCameraInfo * BKE_uvproject_camera_info	(	const struct Object *	ob,
		const float	rotmat[4][4],
		float	winx,
		float	winy )

Create UV info from the camera, needs to be freed.

Parameters

rotmat	can be obedit->object_to_world().ptr() when uv project is used.
winx,winy	can be from scene->r.xsch / ysch.

BKE_uvproject_camera_info_scale()

void BKE_uvproject_camera_info_scale	(	ProjCameraInfo *	uci,
		float	scale_x,
		float	scale_y )

So we can adjust scale with keeping the struct private.
