Change max velocity of pedestrians? #17

Closed pirobot closed 7 years ago

pirobot commented 7 years ago

Hello,

Thank you for this awesome simulator. I was wondering if there is a configuration parameter that would enable me to change the maximum velocity for the pedestrians? I am doing some computer vision tests on detecting groups of moving people and it would be helpful to slow down the motion of the simulated people.

Thanks!

Hi pirobot,

What I did was I found the velocity parameter of the pedestrian under the file [your_workspace]/src/pedsim_ros/pedsim/src/ped_agent.cpp

under the code section: // assign random maximal speed in m/s // normal distribution (mean 1.2, std 0.26) normal_distribution distribution ( 1.2, 0.06 ); vmax = distribution ( generator );

You could try to change the value 1.2 to some other value and recompile the package. This does the job for me. Hopefully it works for you too.

Regards, Chik
