LASER RADAR DEVICE

摘要

A laser radar device includes a searchable distance calculation device 2 to calculate an amount of attenuation at a time of propagation of a light wave from a temporal change in scattered light intensity measured by a marine snow measurement device 1, and calculate a searchable distance in a target search device 4 from the amount of attenuation.

主权项

1. A laser radar device comprising:
a scattered light measurement instrument to measure a temporal change in scattered light intensity of scattered light acquired through scattering of a light wave while propagating; a distance measurement instrument to perform a distance measurement on surroundings by using reflected light of a light wave; a measurable distance calculator to calculate an amount of attenuation at a time of propagation of the light wave from the temporal change in the scattered light intensity which is measured by said scattered light measurement instrument, and calculate a measurable distance in said distance measurement instrument from said amount of attenuation; a target detector to calculate three dimensional data from distances of surrounding points which are measured by said distance measurement instrument, to detect a target from said three dimensional data; a moving route calculator to calculate a moving route of a moving object by using the measurable distance calculated by said measurable distance calculator; a position direction recognizer to measure an acceleration of said moving object to recognize a position and a direction; and a movement controller to move said moving object according to the moving route calculated by said moving route calculator.
