Repeatability - Benewake TFmini Plus Product Manual

① Operating r ange based on a standard whiteboard with reflectivity 90% in indoor condition
② The distance measurement here is absolute accuracy, and the specific repeat accuracy will be described in the next section
2.4.
③ 3.6°is the theoretical value, from which the actual value will be different. The theoretical divergence angle is 6°
④ Only frame rates meet the formula–1000/n (n is positive integer) can be set. The default frame rate is 100Hz.

2.4 Repeatability

The TFmini Plus's range repeat accuracy is directly related to the intensity value measured and the
output frame rate (frequency). The ranging repeat accuracy is characterized by the standard deviation of
ranging. The average ranging accuracy of the TFmini Plus can be estimated by the following formula:
Distance_STD cm
In the formula, x is log
constant coefficients, and the values are as follows:
The above formula only calculates the average reference value. There are some differences in actual
results due to differences in each product.
