Abstract

Non-contact surface flow field measurementhas been widely applied in many engineering applications. This study developed a channel instantaneous flow field measurement system based on calculation of optical flow. Some key issues including spatiotemporal filtering and additive fusion, perspective correction and lens correction, and the mutual correlation matching are discussed in detail. The corresponding treatment scheme has been provided in the developed measurement system. Finally, the system test results are given.
