Livox HAP lidar point cloud abnormal interference issue

[cyhasuka (陌上asuka)]

Hello,
    I am testing with the Livox HAP lidar, and I unexpectedly found that it causes severe interference with other lidar brands during the multi-sensor fusion stage. The point cloud returned after the interference is shown in the attached image. The lidar brand that interferes with HAP is Wanji, a 16-line rotating lidar with a wavelength of 905nm.

    How should I solve this problem? Does the Livox development team encounter such issues during testing? Are there any related filtering methods to filter out these noise points?

    Note: Both of the below images are indoor scenes, so there is no interference from sunlight. The interference disappears after turning off the aforementioned 16-line lidar.The first image shows the clutter generated by interference under normal working conditions, while the second image has a baffle placed 0.5m in front of the two radars (to reflect the 16-line radar's laser into the HAP as much as possible, simulating an extreme situation).

Best regards.
