Hello everyone,
I hope you are doing well. Recently, I have been testing LiDAR sensors from Benewake, Shenyang Optoelectronics, and Garmin used as rangefinders. I have tested several models from mid-range category. Therefore, I would like to share their specifications and performance details for general reference. You may select a suitable model according to your specific application scenario.
Blind Zone:
Ranging curves and error graphs of TF02-Pro, SKP40 and Lidar-lite V3 Respectively:
Indoor ranging error:
Assess the error of three modules with different reflectances in the absence of
ambient light (indoors).
Data analysis and results： The test result is shown as below, TF02-Pro has better ranging error
performance than the other two modules under white and high reflection board. The error of black board in the range of 0~10m is better than Lidar-lite V3 and SKP40, the three modules showed consistent performance within 10~14m.
Outdoor ranging error:
Test Purpose： Evaluate the ranging error of the black and white boards in the outdoor strong
light environment of the three modules.
Data analysis and results： The test result is shown as below, the ranging error of the TF02-Pro is better than the other two modules under white board and 75Klux ambient light. The error of black board in the range of 0~10m is better than Lidar-lite V3 and SKP40, but the error at 14m is worse than the other two modules.
Range performance:
Test Purpose：Evaluate the range of three modules on indoor and outdoor white background
boards.
Data analysis and results： The range is evaluated according to the standard deviation of the ranging value. If the standard deviation is greater than 3cm, it is considered to be out of range. Range performance of TF02-Pro is better than the other two modules.
Indoor and outdoor ranging stability:
Test Purpose： Evaluate the ranging stability of the three modules indoors and outdoors.
Data analysis and results： The result is shown as below, TF02-Pro’s indoor and outdoor
ranging stability performance is better than the other two modules.
Starting at low temperature:
Evaluate whether the three modules can be started normally at -40 °C and the
error between -40 °C and 60 °C.
Data analysis and results： TF02-Pro’s high and low temperature ranging error and temperature drift are better than the other two modules. As it can be seen observed in the following table and figures.
Average power consumption:
Evaluation of module average power consumption;
Using 5V DC power supply, the average power consumption is shown as below. In summary, SKP40 has the lowest average power consumption, TF02 -Pro followed.
