摘要

•An ultrasonic imaging framework for NDE of parts with vertical surfaces is proposed.•Surface reconstruction of parts is derived from point cloud through photos.•By using surface reconstruction as background, ERTM aims at detecting internal flaws.•It succeeds in experiments where multiple flaws lie in parts with vertical surfaces.
