TECHNOLOGY TRANSFER OPPORTUNITY: Photogrammetric Recession Measurement (TOP2-142)

NASA's Technology Transfer Program solicits inquiries from companies interested in obtaining license rights to commercialize, manufacture and market the following technology. License rights may be issued on an exclusive or nonexclusive basis and may include specific fields of use. NASA provides no funding in conjunction with these potential licenses . THE TECHNOLOGY: The testing of materials that ablate as a design function requires detailed time history of the ablation process. The rate at which the surface recedes during testing is a critically important measure of the performance of Thermal Protection System (TPS) materials for example, heat shields on aerospace vehicles. Photogrammetric Recession Measurement (PRM) meets the challenge by recording the surface ofthe ablating model during heating in hyper-thermal test facilities (Arc-Jets), using two high-resolution digital cameras capable of recording at 15 frames per second simultaneously. The cameras are calibrated to yield three-dimensional object space measurements for each stereo pair of images, producing surface recession data over the portion of the model for which both cameras share a view. Image cross-correlation is used widely in several imaging applications, but the new technique of de-warping small interrogation areas of the model surface seen by both cameras and cross-correlating the de-warped views from each camera is an innovation. This acts as a highly accurate feature recognition utility, and can be implemented in several applications.
