avg_logger in calibration branch outputs false mean and std_dev images

[loam]

the values of the c_img need to be updated (incremented) before calculating the moving average values

Good catch! Thanks for the ticket, I've updated the code but I havent been able to verify if it works yet

I would suggest this:

  if (!isnan(z))
  {
    c_img_.at<uint16_t>(v, u) += 1;
    int   c = c_img_.at<uint16_t>(v, u);

    double old_m = m_img_.at<double>(v, u);
    double new_m = old_m + (z - old_m) / (double)c;
