This package is a lightweight wrapper around the 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
barcode_reader_node
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.Subscribed Topics
image (sensor_msgs/Image)- Image input to scan for barcodes.
Published Topics
barcode (std_msgs/String)- Barcodes detected in image input.
Parameters
~throttle_repeated_barcodes (double)- 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.
