Abstract
Official abstract text for this publication.
A laser scanner comprises a light projecting optical system for projecting a distance measuring light, a deflecting optical member for deflecting and projecting the distance measuring light to a measurement area, a distance measuring unit for carrying out measurement based on a reflection light and for acquiring distance data of the measurement area, a second image pickup unit capable of continuously acquiring image data including the measurement area, and a control unit. The control unit has a first image processing unit for acquiring a three-dimensional image based on the image data and on the distance data, and also has a second image processing unit for detecting a mobile object by comparing image data being adjacent to each other in terms of time. The control unit controls the distance measuring unit so that measurement of the mobile object detected in the measurement area is restricted by the second image processing unit.
First claim
Opening claim text (preview).
The invention claimed is: 1. A laser scanner, comprising a light projecting optical system for projecting a distance measuring light along a projection optical axis, a deflecting optical member for deflecting and projecting the distance measuring light to a measurement area, an elevation angle driving unit for rotating said deflecting optical member in elevation direction, a horizontal angle driving unit for rotating said deflecting optical member in horizontal direction, a distanc…
