validateURL failing even when a proper file is present. [closed]
Dear Experts,
I have been trying to use CameraInfoManager::validateURL function with the following code snippet
camera_info_->setCameraName("my_cam");
if (access(camera_calibration_file_param_.c_str(), F_OK) != -1)
{
if (camera_info_->validateURL(camera_calibration_file_param_))
{
camera_info_->loadCameraInfo(camera_calibration_file_param_);
}
else
{
ROS_WARN("Current Camera is Uncalibrated");
}
}
else
{
ROS_WARN("Camera Calibration file not found");
}
I have been continuously getting "Current Camera is Uncalibrated"
warning. The file is found but some parsing error may be. I have ensured that the EOL for the file is LF.
The following is the content of the calibration yaml file that is passed using camera_calibration_file_param_
object copied verbatim from the file itself.
image_width: 640
image_height: 480
camera_name: "my_cam"
camera_matrix:
rows: 3
cols: 3
data: [968.62926614, 0, 348.38163923, 0, 967.56611892, 252.45327611, 0, 0, 1]

I am unable to find the root cause of this issue. Kindly help
