Send published coordinates to a python file

[hsaleem1]

Hi there,

I am using this package and getting 3d coordinates in the following form: xmin: 0.4506256580352783 ymin: -0.3164764642715454 xmax: 0.7936256527900696 ymax: 0.11368180811405182 zmin: -0.25958430767059326 zmax: 0.10506562888622284

I need to ask that can I save those coordinates so that I can call them in a python file?

Thanks for the help.

Hi @hsaleem1 , what I would do is make a "fprintf" and execute the node with a shell redirection (">") to a file. Is it what you need?

Possibly this is a solution. Can you please guide me how to do that?

@hsaleem1 You have a node in which you are subscribed to de bboxes 3d. Then, you get these coordinates and make a fprintf. More or less like that:

void callback(msg) {
  double xmin, ymin, zmin, xmax, ymax, zmax;
  xmin = ...;
  ymin = ...;
  zmin = ...;
  ...
  ...
  ...
  fprintf(stdout, "xmin: %lf\n", xmin);
  fprintf(stdout, "ymin: %lf\n", ymin);
  ...
  ...
}
