Title:
DISTANCE MEASURING DEVICE
Document Type and Number:
Japanese Patent JP2017173187
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a distance measuring device whose ranging precision relative to a ranging object having low reflection rate is improved.SOLUTION: A distance measuring device 1 includes: a pixel arrangement section 401 having Fd for accumulating electrical charges related to intensity of each pixel G; a modulated light emission section 106 for emitting emission modulated light La toward an imaging range 6; a ranging section 102 for measuring a distance D to a ranging object 7 based on a phase difference φ between the emission modulated light La and reflection modulated light Lb reflected by the ranging object 7 to enter into the pixel G; and a modulated light control section 103 for controlling emission intensity of the emission modulated light La so that incident intensity of the reflection modulated light Lb to the pixel G becomes a reference value or more.SELECTED DRAWING: Figure 7
