No Synchronization point found #16

Closed sandeepdutta closed 1 year ago

sandeepdutta commented 1 year ago

I have been trying to generate point clouds using this package. I am using images generated by a ZED Mini camera . I keep getting the warning message below. I have double checked the left & right images have exactly the same timestamp. Any suggestions or insight as to what this error message means ?

Could you verify that the left and right camera info messages also have exactly the same timestamp? The ESSDisparityNode subscribes to 4 topics that must all be synchronized for correct operation.
