Document Type and Number:
Japanese Patent JP6484512
Kind Code:
B2
Abstract:
Detection of sunlight as noise is avoided in obtaining point clouds by using a laser scanner. A laser scanner controlling device includes a sun direction calculating unit 115, a brightness measuring unit 116, and a scan condition setting unit 118. The sun direction calculating unit 115 calculates the direction of the sun. The brightness measuring unit 116 measures the brightness of an image that contains the direction of the sun. The scan condition setting unit 118 sets a condition for restricting laser scanning in the direction of the sun when the brightness is not less than a predetermined threshold value.
