2000 fps real-time vision system with high-frame-rate video recording

—This paper introduces a high-speed vision system called IDP Express, which can execute real-time image processing and high frame rate video recording simultaneously. In IDP Express, a dedicated FPGA (Field Programmable Gate Array) board processes 512 × 512 pixel images from two camera heads by implementing image processing algorithms as hardware logic; the input images and processed results are transferred to standard PC memory at a rate of 2000 fps or more. Owing to the simultaneous high-frame-rate video processing and recording, IDP Express can be used as an intelligent video logger for long-term high-speed phenomenon analysis even when the measured objects move quickly in a wide area. We applied IDP Express to a mechanical target tracking system to record a high-frame-rate video at high resolution for a crucial moment, which is magnified by tracking the measured objects with visual feedback control. Several experiments on moving objects that undergo sudden shape deformation were...
