Abstract: Disclosed herein are various techniques for improving global path optimization in a system that uses camera path for three-dimensional reconstruction. A subset of frames of data for the global path, the key frames, may be used to reduce the computational complexity of the optimization, while preserving full three-dimensional detail in the optimized model by relating other measurements to the optimized key frame path.

Abstract: The present invention relates to backsheets containing formulated thermoplastic polyolefin (TPO) which may be used with photovoltaic modules. More specifically, the backsheets of the present invention have a first exterior layer that comprises TPO and a polyamide, such that a residual fusion heat after lamination of that layer is at least 40 J/g. Using such a layer, sufficient bonding to the encapsulant of a photovoltaic module can be achieved, while maintaining high heat resistance, having low distortion at high operating temperatures, and having relatively low high water vapor transmission rate. The present invention also relates to photovoltaic modules containing the backsheets of the present invention, as well as to methods for making the backsheets of the present invention.
