Abstract: A scale estimating method through metric reconstruction of objects using a smart device is disclosed, in which the smart device is equipped with a camera for image capture and an inertial measurement unit (IMU). The scale estimating method is adapting a batch, vision-centric approach only using IMU to estimate the metric scale of a scene reconstructed by algorithm with Structure from Motion like (SfM) output. Monocular vision and noisy IMU can be integrated with the disclosed scale estimating method, in which a 3D structure of an object of interest up to an ambiguity in scale and reference frame can be resolved. Gravity data and a real-time heuristic algorithm for determining sufficiency of video data collection are utilized for improving upon scale estimation accuracy so as to be independent of device and operating system. Application of the scale estimation includes determining pupil distance and 3D reconstruction using video images.

Abstract: An adjustable rear view mirror for an automotive vehicle adapted to be mounted on a door and comprising a housing including a mounting flange at one end and an opening adjacent the other end, an end bracket in the housing, a mirror and a mounting mechanism supporting the mirror in the opening of the housing. The mounting mechanism comprises an adaptor connected to the mirror, a cup, a sleeve and a retainer. The adaptor includes a spherical portion having a slot. The cup is mounted on the end bracket, or alternatively, on the housing and engages the outer spherical portion of the adaptor. The sleeve has a rib on its outer surface and spaced from the rib is a groove on the inner surface of the sleeve. The sleeve engages the inner surface of the adaptor and is positioned so the rib is received in a slot of the adaptor. The retainer engages the inner surface of the sleeve and has a rib received in the groove of the sleeve. A spring yieldingly urges the retainer on the cup.
