Abstract
For many years, photogrammetry has been in use at TRW. During that time, needs have arisen for highly repetitive measurements. In an effort to satisfy these needs in a timely manner, a specialized Robotic Video Photogrammetry System (RVPS) was developed by TRW in conjunction with outside vendors. The primary application for the RVPS has strict accuracy requirements that demand significantly more images than the previously used film-based system. The time involved in taking these images was prohibitive but by automating the data acquisition process, video techniques became a practical alternative to the more traditional film- based approach. In fact, by applying video techniques, measurement productivity was enhanced significantly. Analysis involved was also brought `on-board' to the RVPS, allowing shop floor acquisition and delivery of results. The RVPS has also been applied in other tasks and was found to make a critical improvement in productivity, allowing many more tests to be run in a shorter time cycle. This paper will discuss the creation of the system and TRW's experiences with the RVPS. Highlighted will be the lessons learned during these efforts and significant attributes of the process not common to the standard application of photogrammetry for industrial measurement. As productivity and ease of use continue to drive the application of photogrammetry in today's manufacturing climate, TRW expects several systems, with technological improvements applied, to be in use in the near future.
