Title:
DISTANCE MEASURING DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/082628
Kind Code:
A1
Abstract:
A distance measuring device (100). The distance measuring device (100) comprises: a distance measuring wheel (110), which is configured to measure the distance traveled by the distance measuring wheel (110); a support unit (120), which is connected to the distance measuring wheel (110) and comprises at least two auxiliary rollers (121, 122), wherein in a working state, contact points of the at least two auxiliary rollers (121, 122) and contact points of the distance measuring wheel (110) are coplanar; an acceleration sensor, which is arranged at the distance measuring wheel (110) or the support unit (120) and is configured to measure angle data of the distance measuring device (100) during traveling, wherein the angle data comprises pitch angle data; and a processor, which is electrically connected to the acceleration sensor and is configured to determine, according to the angle data and the distance traveled by the distance measuring wheel (110), location data for plotting a trajectory of the distance measuring device (100) during traveling. Changes in the undulations of a route traveled by the distance measuring wheel (110) can be plotted.
