| description | The invention discloses a printing platform lifting height self-adaptive adjustment method in the DLP 3D printing process, and relates to the technical field of target detection, target segmentation and intelligent control. The method can adapt to different resin materials and equipment. Comprising the following steps that an optical camera is adopted to carry out image acquisition on a marker in a printing scene; the position of the marker is judged through a YOLOv5 network, and the liquid level height of the resin and the liquid level height of the fluorinated oil are determined; whether liquid insufficiency exists or not is judged according to the liquid level height information, and a water pump is controlled to supplement the insufficient liquid; and the optimal lifting height of the printing platform in next-layer printing is calculated according to the liquid level height information. By the adoption of the printing platform lifting height self-adaptive adjusting method in the DLP 3D printing process, |
