Some Data Were Lost
Symptoms
When the scan is triggered by the encoder, the intensity image, depth map, and point cloud contain horizontal black bands or are not displayed at all. Meanwhile, a prompt of Some data were lost popped up in the lower right.
Possible Causes
The rate at which the encoder triggers scanning exceeds the max scan rate of the laser profiler.
Solution
Please try the following solutions based on the actual situation:
-
Decrease the Z-Axis Height for the ROI in the profile mode: Reduce the amount of data to be processed to enhance the max scan rate of the laser profiler.
Adjust the Z-Axis Height to as small as possible while making sure the needed data is not trimmed off.
-
Decrease Exposure Time (timed exposure) or Total exposure time in HDR Exposure Settings (HDR exposure mode) in the profile mode to enhance the max scan rate of the laser profiler.
After decreasing Exposure time or Total exposure time, the brightness of the laser lines in the raw image will decrease. If the brightness is too low, increase Analog Gain in the profile mode.
-
Increase Trigger Interval in the scan mode to reduce the rate at which the encoder triggers scanning.
Adjusting Trigger Interval while Trigger Signal Counting Mode is unaltered changes the Y-axis resolution of the scan data.
