| 发明名称 | Undulation detection device and method | ||
| 摘要 | An undulation detection device includes a two-dimensional sensor configured to emit a sensing wave for distance measurement in a plurality of directions forming different lateral and vertical angles and to measure respective distances to objects from which the sensing wave is reflected, and a processor performs detecting an undulation of the measurement surface or an obstacle placed on the measurement surface from which the sensing wave is reflected, on the basis of a difference among the distances in the different directions, the difference being measured by the two-dimensional sensor, and outputting an undulation detection report, when an in-plane size of the undulation of the measurement surface or the obstacle placed on the measurement surface is equal to or more than a threshold. | ||
