5.4. Accuracy Spatial Distribution
To check the accuracy spatial distribution, 50 frames of data are recorded while using CE30-C to detect white wall (90%
reflectivity) in the distance of 100cm. The error between the average value of each pixel column and the true distance is
used to stand for accuracy, and the standard deviation of the average value of each pixel column between frames is used
to stand for repeatability.

6. Outdoor Uses
6.1. Test Conditions
When CE30-C is used in outdoor environment, due to the interference of ambient light, CE30-C’s close blind zone,
measurement error and standard deviation will increase. The test in this section is made under 30kLux ambient light.
CE30-C is placed back to the sun and detect the white board that has 90% reflectivity and is illuminated by sunlight.
6.2. Outdoor Accuracy
Begin in the distance of 15cm, 50 frames of data are recorded per 10cm. Followings are the results of the recorded data.
