Measuring body points on automobile drivers using multiple cameras

摘要

Methods are given for measuring 3D points on human drivers of automobiles. Points are natural body features marked by special targets placed on the body. The measurements are needed for improved comfort and accommodation in automotive seat design. The measurement methods required hardware instrumentation in the automobile and development of algorithms for off-line processing of the acquired data. This paper describes the use of multiple cameras to measure 3D locations within the driver's workspace. Results obtained show that measurement error in X, Y and Z coordinates is expected to be less than 1.0 mm on the lab bench and 2.0 mm in the car, and that combined 3D error is expected to be less than 2.0 mm and 3.0 mm, respectively.
