Circles not found in both Image and PointCloud Data

I believe that I am providing the right set of inputs on three topics:

1. Camera info - With the Right intrinsics and Projection matrix of Camera I am using
2. Image frame - USB Cam ROS package's Raw Image topic
3. Point Cloud from the Velodyne Driver -> / Velodyne_points
4. Circle Distance: 0.29
5. Circle Size: 0.10

But the calibration is always failing for me. Moreover, when I run the package, circles on calibration board are not found in both the image and the point cloud data. I even start receiving few errors like:

[pcl::SampleConsensusModel::getSamples] Can not select 0 unique points out of 0!
[pcl::RandomSampleConsensus::computeModel] No samples could be selected!
[pcl::SampleConsensusModel::getSamples] Can not select 0 unique points out of 0!
[pcl::RandomSampleConsensus::computeModel] No samples could be selected!
[pcl::SampleConsensusModel::getSamples] Can not select 0 unique points out of 0!
[pcl::RandomSampleConsensus::computeModel] No samples could be selected!

I check the saved frame and pointcloud data. The image frame is clear and the pointcloud has many points.

Try to visualize the data which are processed by RANSAC - are the points capturing the marker there?
