レーザレーダ装置
Document Type and Number:
Japanese Patent JP6658375
Kind Code:
B2
Abstract:
A laser radar device includes a storage unit, a sensing level setting unit, a time measuring unit and a correcting unit. The storage unit stores an emitting direction of an inner reflection-measurement laser light that is a second laser light of three laser lights include a first laser light, the second laser light and a third laser light when a distance between spots defined by the first and the third laser lights at a maximum sensing distance is less than or equal to a size of an external subject. The sensing level setting unit sets a sensing level where an inner reflection light can be sensed when emitting directions of the laser lights are in the emitting direction of the inner reflection-measurement laser light. The time measuring unit measures an inner light-reflection sensing time. The correcting unit corrects the distance calculation formula, based on the inner light-reflection sensing time.
