RectArrayToDensityImage¶
What is this?¶

Convert rect array (jsk_recognition_msgs/RectArray
) to density image (sensor_msgs/Image
, 32FC1
).
Subscribing Topic¶
~input/image
(sensor_msgs/Image
)Raw image.
~input/rect_array
(jsk_recognition_msgs/RectArray
)Array of rectangle.
Publishing Topic¶
~output
(sensor_msgs/Image
,32FC1
)Density image computed based on the number of rectangles overlaid.
Parameters¶
~approximate_sync
(Bool, default:False
)Whether to use approximate for input topics.
~queue_size
(Int, default:100
)How many messages you allow about the subscriber to keep in the queue. This should be big when there is much difference about delay between two topics.
