System and method for vehicle condition assessment using correlated three-dimensional geometric analysis and on-board diagnostic data

Abstract

A system and method for mobile-based vehicle inspection system operates in conjunction with a portable data device acquiring a continuous sequence of exterior images of a vehicle while the device is moved relative to the vehicle, together with motion data from an integrated inertial measurement unit. The application generates a three-dimensional geometric representation of at least a portion of the vehicle based on the image data and motion data. When manufacturer reference information is available, the geometric representation is analyzed relative to manufacturer-provided data to identify geometric deviations indicative of deformation, misalignment, or non-standard parts. When manufacturer reference information is unavailable, the geometric representation is analyzed to identify structural anomalies based on internal geometric relationships. On-board diagnostic data received from the vehicle is evaluated in relation to the geometric analysis to corroborate, complement, or supplement detected conditions. A diagnostic assessment indicative of a physical condition of the vehicle is generated.
