Title:
IMAGE PROCESSING DEVICE AND DISTANCE MEASURING DEVICE
Document Type and Number:
Japanese Patent JP2020041973
Kind Code:
A
Abstract:
To realize an image processing device which can calculate the distance to a subject with good accuracy.SOLUTION: According an embodiment, the image processing device comprises an acquisition unit and a processing unit. The acquisition unit acquires a first image for calibration in which a first subject is imaged and a second image in which a second subject is imaged, the images being captured using an imaging device having an image sensor for receiving light having passed through a filter unit provided with a first filter region that passes light of a first wavelength band and a second filter region that passes light of a second wavelength band, the first and second wavelength bands including a command wavelength band. The processing unit acquires, using the image sensor, the first image for calibration in which the first subject is imaged and the second image in which the second subject is imaged, and calculates the distance to the second subject using the first and second images.SELECTED DRAWING: Figure 8
