3D-Model 3D-Pose DNN CVPR18
We propose a scalable, efficient and accurate approach
to retrieve 3D models for objects in the wild. Our contri-
bution is twofold. We first present a 3D pose estimation
approach for object categories which significantly outper-
forms the state-of-the-art on Pascal3D+. Second, we use
the estimated pose as a prior to retrieve 3D models which
accurately represent the geometry of objects in RGB im-
ages. For this purpose, we render depth images from 3D
models under our predicted pose and match learned im-
age descriptors of RGB images against those of rendered
depth images using a CNN-based multi-view metric learn-
ing approach. In this way, we are the first to report quanti-
tative results for 3D model retrieval on Pascal3D+, where
our method chooses the same models as human annota-
tors for 50% of the validation images on average. In ad-
dition, we show that our method, which was trained purely
on Pascal3D+, retrieves rich and accurate 3D models from
ShapeNet given RGB images of objects in the wild.
