<> <> This package is a lightweight wrapper around the [[http://zbar.sourceforge.net/|Zbar]] barcode processing library. It provides a node and a nodelet with equivalent interface. The `image` topic is a lazy subscription that is active only when the `barcode` topic has a client. == Node API == {{{ #!clearsilver CS/NodeAPI name = barcode_reader_node desc = The `barcode_reader_node` listens to image data (camera or otherwise) on the incoming topic, outputs the contents of any barcodes detected in the images. sub { 0.name = image 0.type = sensor_msgs/Image 0.desc = Image input to scan for barcodes. } pub{ 0.name = barcode 0.type = std_msgs/String 0.desc = Barcodes detected in image input. } param { 0.name = ~throttle_repeated_barcodes 0.type = double 0.desc = Time (s) to throttle any repeated barcode scans. If `0.0`, all detected barcodes will be output as fast as the node can process the incoming images. } }}} == Nodelet API == Same API as node, available as `zbar_ros/barcode_reader_nodelet`. ## AUTOGENERATED DON'T DELETE ## CategoryPackage
