Hello, I'm working with the SR4K and the swissranger_camera driver on boxturtle. I was wondering if there was any calibration procedures for the driver. I got the point cloud running in rviz with a camera and it looks like the data from the sr4k is lagging behind the color camera images by a few tenths of a second. Does anyone have any ideas as to the cause of this? I tried adjusting the integration time, but that did not seem to help. Thanks, -Bill
