Abstract: The present invention relates to a dust measurement device for implementing a dust distribution image through a non-coplanar stereo vision camera, and provides a dust measurement device comprising: a stereo vision camera which includes a first camera for obtaining a true color image and a second camera for obtaining an infrared image; a control unit for generating a fine dust distribution image by using a light amount ratio of the amount of light obtained from a first pixel array of the first camera to the amount of light obtained from a second pixel array of the second camera; and a display device for outputting the fine dust distribution image.

Abstract: The present invention provides an image processing apparatus comprising: a first camera obtaining a true-color image by capturing a subject; a second camera spaced apart from the first camera and obtaining an infrared image by capturing the subject; and a control unit connected to the first camera and the second camera, wherein the control unit matches the true-color image and the infrared image and obtains three-dimensional information of the subject by using the matched infrared image in a region corresponding to the matched true-color image and a valid pixel.
