RectArrayToDensityImage¶

What is this?¶

../../_images/rect_array_to_density_image.png

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.
