How can I get the calibration data for camera and lidar data which I captured?

I have recorded the point cloud data using velodyne - VLP-16 Puck sensor and captured the data using logitech C270 (Normal Webcam). Now, I need to process the data for sensor fusion based object detection concept. For that, I need calib.mat file. But, I need to know how to calculate or get that .mat file. Without use of calib.mat (Calibration Mat file) file, I cannot detect the object in both the images(Image and .pcd data) in sensor fusion code.
People who are working or excel in this domain, kindly assist me on this.
I tried to get the data using camera calibrator but few values are null (means '0'). With that data i couldn't process further. Also i have a doubt, if I created the calib.mat file using one image, is that fine for all images(image & pcd data)? No need to change for different location of captured data?
Thanks in advance.

In order to get the calibration between lidar and camera, you can use the lidarCameraCalibrator app. This is a good place to help you get started with the process of calibration. You can refer to the following page for more details on getting started with the app: Get Started with Lidar Camera Calibrator.
