MID-40 Sensor Precision at Minimum Working Distance 1m

dex

Hi all

Good morning! Please forgive my abruptness if this question being improper here. We would like to know if the LIVOX MID-40 is being placed at 1m distance, what would the accuracy may be for x/y direction, respectively?

According to the spec, it reads "Range Precision: 1\sigma @ 20m = 2cm", can we suggest that

step1. 2\sigma is 4cm (@20m)
step2. by proportion: "4cm:20m = x cm:1m", we get x = 0.2cm
step3. in statistics, 2\sigma could cover 95% of the possible result
step4. hence we have precision 0.2cm @ 1m (2\sigma)

Is such deduction reasonable to the sensor? Please kindly advise if anyone has such experience and willing to share. Thank you in advance.

Best Regards
Dex

Hi Dex，
The σ comes from the three-sigma rule of thumband is the evaluation standard for equipment accuracy.

The technical index "＜ 2cm/1σ(@ 20m) " means that the pointcloud Range Precision at 20 meter of the device with 68.2% probability is within 2cm.
