However, even when a device captures highly accurate individual measurements, chaining them will result in an accumulation of noise and tiny measurement uncertainties. Over time, the estimated motion will start to deviate from the true motion, which is known as \u2018drift error\u2019. This can often be observed as a slight bending of long corridors that are actually straight. All available SLAM systems \u2013 regardless of whether these use LIDARs or other sensors \u2013 are inherently affected by this phenomenon.<\/p>\n
The innovative NavVis Precision SLAM technology significantly reduces drift error and improves the SLAM accuracy. This is particularly evident in cases where complementary techniques such as loop closures cannot be deployed if, for example, the building\u2019s layout does not allow for it. Precision SLAM even improves accuracy when SLAM anchors are used to incorporate ground control points into the mapping process.<\/p>\n
\u201cI am very excited about our new Precision SLAM technology. We are always striving for the highest possible map and point cloud accuracy and improving SLAM is a critical component to being successful. It is widely known among SLAM developers and users that complementary approaches such as loop closures or ground control points are needed to achieve a high accuracy. However, with the Precision SLAM technology we have developed an approach that not only nicely complements the former techniques but is especially evident when these have little effect or cannot be used.\u201d<\/p>\n
