IMU suggestion?

[rahulsharma11]

Hi, I have been using Fast_LIO with Livox Avia for my 3D scanning project and it is very good. Now i want to integrate external IMU for better longer run accuracy. I can use any of below-

1. Livox Avia
2. Velodyne puck

I have few options for selecting IMU-

1. MTi-610 (https://store.clearpathrobotics.com/products/mti-610)
2. NGIMU (https://x-io.co.uk/ngimu/)
3. WitMotion IMU (https://www.wit-motion.com/digital-inclinometer/witmotion-hwt905-rs485-high-accuracy.html)

Any suggestion for which IMU should I go in term of accuracy and support? Or any other IMU suggestion will also be considered.

Thanks.

@XW-HKU please advise on the same. Even I am waiting to use FASTLIO with velodyne.

Any light would be helpful

The quality and accuracy of IMU are important, but the extrinsic and synchronization of LiDAR-IMU sometimes are more significant. For LiDARs without internal IMU, our recent work LI-Init (https://github.com/hku-mars/LiDAR_IMU_Init) is recommended.

Hi thanks for the wonderful work. I will give this a try. Apart from that , my original question was which IMU will you prefer to use? I provided few options as well. Any suggestions on that? Thanks.

I didn't try the options you mentioned, so I cannot tell which one is the best. But it is recommended to read the datasheet of each product, the IMU with low-level noise and bias might be good.
