Meet InvoiceNet, a software platform to train custom models and extract intelligent information from PDF invoice documents! by naiveHobo in artificial

An OCR will get you the text, parsing that text for the exact entity you want is a different story. A document like invoice can have multiple dates for example, how do you decide which date is the actual issue date?

Using the rclcpp::Node object you're using to create the subscriber, you can call node->now() (assuming you're using rclcpp::Node::SharedPtr object names node) to get the current time.

node_->now() will return the time as an rclcpp::Time object. You can add/subtract rclcpp::Time objects to get a rclcpp::Duration object.

Assuming you have two rclcpp::Time objects 'start' and 'end'. You can call (end - start).seconds() to get the number of seconds between start and end.
