Title: Innovations by Gangyi Jiang: Pioneering Patents in 3D Measurement Technologies
Introduction
Gangyi Jiang is a prominent inventor based in Zhejiang, China, known for his significant contributions to the field of 3D imaging and measurement technologies. With an impressive portfolio of 14 patents, his work focuses on enhancing visual perception and measurement accuracy, making substantial advancements in optical microscopy.
Latest Patents
Among his latest patents is the "3D-HEVC inter-frame information hiding method based on visual perception." This innovative method comprises two crucial steps: information embedding and information extraction. In the embedding phase, human visual perception characteristics are utilized to obtain stereo salient images. By employing a stereo image salient model, these images are classified into salient and non-salient blocks using an Otsu threshold. The method modifies coding quantization parameters according to different modulation rules specific to each region, enabling effective information embedding. In the extraction step, this process allows for blind extraction of secret information without needing the original video or any additional side information, which notably reduces the impact on the subjective quality of stereo video.
Another noteworthy patent is the "Microscopic three-dimensional measurement system and method based on moving diaphragm." This invention integrates a diaphragm into the existing optical microscopic imaging system. By limiting the angle of light irradiation during imaging, it significantly reduces the diameter of the blur circle, thus extending both the depth of field and the depth measurement range. The method employs two images with varying light incident directions to create a disparity map for 3D scene reconstruction. To further enhance accuracy, a quadratic function is utilized to express the non-linearity of the imaging model, thereby minimizing measurement errors.
