RectArrayToDensityImage

What is this?

../../../../_images/rect_array_to_density_image1.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.
