== About ==
text_locator is a ROS package that can detect and recognize text in images from the MS kinect / Asus Xtion sensors. Also, it can give you spatial information about the text, ie. where the text is in the 3D space, with respect to the sensor.

== Installation ==
Install the text_locator package from the github repo (see [[https://github.com/vonovak/text_locator/blob/master/README.md|here]]). Then download the CCV library from [[http://libccv.org/doc/doc-swt/|here]], and compile it. The result will be a static library file, libccv.a. Copy this file to the /lib folder of the package.

To compile CCV, extract the tarball, cd to [extractedCCV]/lib folder, run ./configure followed by make. When configuring, the 'swscale' is the only component that is needed. The other compilation options (enable SSE2, use openmp etc..) are optional.

== Launching ==
Run

{{{
roslaunch text_locator text_locator.launch
}}}
The output of the node is advertised on text_locator_topic.

== Documentation ==
More detailed documentation is included in the git repo's readme file [[https://github.com/vonovak/text_locator|here]].
