摘要： A printed circuit board inspection apparatus can inspect a mounting state of a component by generating depth information on the component by using a pattern of light reflected from the component mounted on a printed circuit board received by an image sensor, generating two-dimensional image data for the component by using at least one of light of a first wavelength, light of a second wavelength, light of a third wavelength, and light of a fourth wavelength reflected from the component received by a first image sensor, inputting the depth information and the two-dimensional image data for the component into a machine learning-based model, obtaining depth information with reduced noise from the machine learning-based model, and using the noise-reduced information.

摘要： A method, performed by a computer, for volumetrically determining a mid-sagittal plane (MSP) from a plurality of magnetic resonance (MR) images of a brain is disclosed. The plurality of MR images is received and converted into a 3D volume image defined in a 3D coordinate space. Semantic segmentation of an anterior commissure (AC) region, a posterior commissure (PC) region, and a third ventricle region in the 3D volume image is performed based on a pre-trained segmentation model to generate a 3D mask image labeled with the AC region, the PC region, and the third ventricle region. Based on the labeled 3D mask image, a 3D volumetric image of the segmented third ventricle region is constructed. The MSP is determined based on the 3D volumetric image of the third ventricle region.

The plurality of MR images is received and converted into a 3D volume image defined in a 3D coordinate space. Semantic segmentation of an anterior commissure (AC) region, a posterior commissure (PC) region, and a third ventricle region in the 3D volume image is performed based on a pre-trained segmentation model to generate a 3D mask image labeled with the AC region, the PC region, and the third ventricle region. Based on the labeled 3D mask image, a 3D volumetric image of the segmented third ventricle region is constructed. The MSP is determined based on the 3D volumetric image of the third ventricle region.

摘要： An apparatus for inspecting components may include a processor for: determining exterior information of a first component mounted on a first printed circuit board; inspecting a mounting state of the first component by using inspection information of a second component having a first similarity value, when the first similarity value is higher than or equal to a preset reference similarity value, and updating the inspection information of the plurality of components by using the inspection information of the first component matched with the inspection information of the second component, when it is determined that the mounting state of the first component is good.
