3D Imagers create ("reconstruct") digital models of real scenes from light. They are sometimes called "3D cameras," "3D scanners" or "depth cameras.” 3D Imagers are composed of imaging sensors and scene reconstruction engines ("SREs"). The sensors are the "digital eyes" that detect the light. The SREs are the "digital brains" that reconstruct the 3D models from the images. Although Quidient promotes development of advanced sensors, our main focus is on 3D scene reconstruction. Our flagship product is an SRE called a Locale Engine™. Quidient's Locale Engines are based on our proprietary Intrinsic Imaging™ approach, which handles generalized light fields in a way that is intrinsic to human perception. Intrinsic Imaging uniquely enables dense reconstruction of quotidian (everyday) scenes.

3D FROM A SINGLE IMAGE |
Quidient Locale Engines typically use multiple images to reconstruct quotidian scenes. But, once a generalized scene light field has been sampled and modeled, Quidient’s SREs can actually reconstruct 3D objects from a single image as well. This video demonstrates that 3D models of a hail-damaged car panel and a life-sized mannequin head have been reconstructed from single images. The scene in both cases is a conference room lit with preexisting fluorescent lights. The objects in both cases are featureless, dark and specular. The camera used is polarimetric and equipped with a conventional lens, although Quidient’s SREs can work with conventional (B&W or RGB) cameras as well. The distance from the camera to the auto panel is about one meter. The distance from the camera to the mannequin is about three meters (although camera to subject distances into the hundreds of meters are also possible with telephoto lenses.)
