Examples of frequently used scripts

General information about scripts

Custom scripts are used for partial automation of processes while configuring Face PSIM. In the Programming Guide document there is the description of programming objects and methods which are in use for scripts creation in Axxon PSIM.

Script for faces verification

The verification mode compares the face captured in the frame with the user photo stored on the disk at <Axxon PSIM installation folder>\Bmp\<Person>. It also determines the face parameters: emotions, temperature, face concealment (mask), gender, facial hair.

To perform face verification, do the following:

1. Create the script:

   if(Event.SourceType == "MACRO" && Event.Action == "RUN" && Event.SourceID == "1")
   {
      DoReactStr("FIRSERVER","1","VERIFY_START","cam_id<1>,p_id<15>,wait<10>");
   }

   Note

   • 1 — the identifier of the Face recognition server object;
   • VERIFY_START — user verification command;
   • cam_id<1> — camera identifier. If you use the VisionLabs face recognition module, instead of camera identifier, specify the identifier of the Face detection object; 
   • p_id<15> — the name of the file with photo in the <Axxon PSIM installation folder>\Bmp\<Person> folder without resolution (for example, 15 for the 15.bmp file);
   • wait<10> — the waiting time in seconds for the face to appear.
2. Run the first macro. If the user from the photo does not appear in front of the camera in 10 seconds, the Verification declined event will be displayed. In case the user appears, the Successful verification event will be displayed immediately showing the similarity percentage of the captured face with the user photo stored on the disk. 

The face verification is completed.

Script for adding a reference face to the database from a file

A reference face can be added to the database from a file with photo using the ADD_PERSON_FROM_FILE reaction of the FIRSERVER object.

Parameters:

• filename — full name of the file with the photo. Files with the JPG, BMP, GIF, PNG extension are acceptable;
• name — the name of the added user;
• surname — the surname of the added user;
• department — the department to which the user will be added;
• comment — any text commentary.

Example of the script usage:

if(Event.SourceType == "MACRO" && Event.Action == "RUN" && Event.SourceID == "1")
{
   DoReactStr("FIRSERVER","1","ADD_PERSON_FROM_FILE","filename<c:\\iso_small.jpg>,name<Jane>,surname<Kramer>,department<Department 1>,comment<>");
}

If the face was successfully added to the reference faces database, the ADD_PERSON_FROM_FILE_OK event will be displayed in the Debug window. If there are any errors when adding the reference face, the ADD_PERSON_FROM_FILE_ERROR event will be displayed (see FIRSERVER events).
