Hello everyone,
I'm trying to deploy track object using DL on Raspberry Pi follow this example of Detect and Track Object Using Deep Learning on Raspberry Pi, however, it gives me the following error:
The function is:
function obj = raspiObjectTracker()
%RASPIOBJECTTRACKER Construct an instance of this class
% Detailed explanation goes here
hb = raspi.internal.BoardParameters(obj.BoardDetails.Name);
hostname = hb.getParam('hostname');
username = hb.getParam('username');
password = hb.getParam('password');
obj.BoardDetails.DeviceAddress = hostname;
obj.BoardDetails.UserName = username;
obj.BoardDetails.Password = password;
end
Has anyone experienced this error, and could provide some help?
Thanks in advance.

Hi,
Can you please try following steps?
  • Execute this in MATLAB command window
>> openExample('raspberrypiio/DetectAndTrackObjectUsingDeepLearningOnRaspberryPiExample')
>> edit raspiObjectTracker
  • At line no. 49, replace "hb = raspi.internal.BoardParameters(obj.BoardDetails.Name);" with "hb = codertarget.linux.remotebuild.BoardParameters(obj.BoardDetails.Name);"
  • And then execute following command and follow the steps as metioned in the example
>> rehash toolboxcache; rehash path; rehash;
Thanks,
