AI Technical Summary
Technical Problem
Existing techniques for estimating the three-dimensional shape of transparent objects fail to obtain accurate point cloud data due to the influence of background colors and shadows, particularly when using silhouette images.
Method used
An imaging device that irradiates light onto a transparent or translucent subject, measures distance using reflected light, and includes a light weakening unit to enhance the visibility of transmitted light, allowing for improved point cloud data acquisition.
Benefits of technology
The solution strengthens reflected light from transparent subjects, increasing the likelihood of accurately acquiring point cloud data and reproducing the local features of transparent objects.

Abstract
To increase the possibility that point group data on a transparent object can be obtained suitably.SOLUTION: An image pick-up device according to an embodiment of the present disclosure includes: an image pick-up unit that radiates light on a subject which is at least partially transparent or semi-transparent and measures the distance to the subject by using reflected light of the light; and a light weakening unit arranged opposite to the image pick-up device with the subject interposed therebetween to weaken light that has passed through the subject.SELECTED DRAWING: Figure 11
