The invention discloses a breadth brightness detection method and system for an energy radiation device and a calibration method, and the method comprises the steps: enabling a camera device to shoot detection points, projected on a development device, of the energy radiation device at different shooting positions, so as to obtain a plurality of to-be-detected images; wherein the positions of the detection points projected by the energy radiation device at different shooting positions are different, and the detection point images in each to-be-detected image are located in the same area of the to-be-detected image; and determining breadth brightness detection data of the energy radiation device based on the imaging characteristics of the detection points in the to-be-detected images. According to the invention, the movable camera device is used for carrying out brightness detection on the breadth of the energy radiation device, and the method is suitable for energy radiation devices with various breadth sizes. Moreover, the detection point image projected by the energy radiation device is shot by using a certain designated area of the camera device all the time, so that errors caused by the camera device can be ignored, and the detection precision is ensured.
Description
technical field [0001] The present application relates to the technical field of 3D printing, and in particular to a method, system, calibration method, preprocessing method for 3D printing, 3D printing equipment, control method and control device for a web brightness detection method of an energy radiation device. Background technique [0002] Photocuring 3D printing equipment provides light energy through energy radiation devices to shape printing materials. In surface exposure printing equipment, the projection surface of the energy radiation device often has uneven brightness. Even if a solid color pattern is projected, there will still be uneven brightness on the format, such as bright in the middle and dark around, or interlaced light and dark. Since the projection brightness of the energy radiation device is directly related to the energy received by the printing material, the uneven brightness of the web will make the sliced pattern projected by the energy radiatio...
