This paper introduces an intelligent high-frame-rate video recording system that can automatically detect strong acceleration in images and record corresponding images with dimensions of 512 × 512 pixels at 1000 fps. To capture high-frame-rate images of crash behavior, a contact detection algorithm is software-implemented on a high-speed vision platform, IDP Express, which can process and record input images at 1000 fps. The algorithm can estimate the external force acting on the target by calculating its position, velocity, and acceleration in real time. Several experiments were performed using image-based triggers for contact detection, and a video of the crash behavior was automatically recorded to verify the effectiveness of our system.
