When I fly with LIDAR each flight has overlaps at the edges, and additional sidelap, which results in overlapping points where the flight lines come together. Is there a way to filter the points so the density is consistent right across the point cloud?

You may want to try the 'Subsample' method (https://www.cloudcompare.org/doc/wiki/i ... CSubsample) with the 'Space' method, and set a low enough 'min space between points' so as to reduce the density in these overlapping areas.

some additional ideas:

Option 1)
Tools-->Other-->Compute Geometric Features --> use one of the density options, may be this way you're able to highlight the overlapping areas by narrowing the output SF in the inspector.

Option 2) If hte dataset is not very big, separate each pass using the "GPS time" SF, hving each pass separate compare distances between passes. Then you can filter out by distance.
