This filter processes the modbus data from a Flir Thermal Imaging camera and removes the datapoints for whcih there is not a matching xxxValid data point with a non-zero value. It also removes the xxxValid data points.

Any deltaXX entries with a value of zero are also removed as are any spotXX entries. The spot and delta values do not have a corresponding xxxValid entry, so hence a zero value is used as a trigger to remove them.

A mechanism is also available for labelling the areas. This is done by configuring an array of labels with the names to give the areas.

To build FogLAMP Flir Validity filter plugin:

$ mkdir build
$ cd build
$ cmake ..
$ make

• By default the FogLAMP develop package header files and libraries are expected to be located in /usr/include/foglamp and /usr/lib/foglamp
• If FOGLAMP_ROOT env var is set and no -D options are set, the header files and libraries paths are pulled from the ones under the FOGLAMP_ROOT directory. Please note that you must first run 'make' in the FOGLAMP_ROOT directory.

You may also pass one or more of the following options to cmake to override this default behaviour:

• FOGLAMP_SRC sets the path of a FogLAMP source tree
• FOGLAMP_INCLUDE sets the path to FogLAMP header files
• FOGLAMP_LIB sets the path to FogLAMP libraries
• FOGLAMP_INSTALL sets the installation path of Random plugin

NOTE:

• The FOGLAMP_INCLUDE option should point to a location where all the FogLAMP header files have been installed in a single directory.
• The FOGLAMP_LIB option should point to a location where all the FogLAMP libraries have been installed in a single directory.
• 'make install' target is defined only when FOGLAMP_INSTALL is set

Examples:

• no options

  $ cmake ..

• no options and FOGLAMP_ROOT set

  $ export FOGLAMP_ROOT=/some_foglamp_setup

  $ cmake ..

• set FOGLAMP_SRC

  $ cmake -DFOGLAMP_SRC=/home/source/develop/FogLAMP ..

• set FOGLAMP_INCLUDE

  $ cmake -DFOGLAMP_INCLUDE=/dev-package/include ..

• set FOGLAMP_LIB

  $ cmake -DFOGLAMP_LIB=/home/dev/package/lib ..

• set FOGLAMP_INSTALL

  $ cmake -DFOGLAMP_INSTALL=/home/source/develop/FogLAMP ..

  $ cmake -DFOGLAMP_INSTALL=/usr/local/foglamp ..
