Abstract: An apparatus includes one or more light source groups, a camera; one or more memories configured to store one or more first images acquired in advance, and one or more processors communicatively connected to the one or more light source groups, the camera, and the one or more memories, wherein the one or more processors are configured to acquire a second image by controlling a first light source group among the one or more light source groups and the camera and irradiating light beams to a substrate on which an object is coated, and determine a coating state of the object based on the one or more first images and the second image.

Abstract: The present disclosure provides an apparatus. The apparatus according to the present disclosure comprises: at least one first light source configured to irradiate illumination light to an object on a reference surface; at least one second light source configured to irradiate pattern light to the object, a plurality of cameras configured to capture one or more illumination images and one or more pattern images; and one or more processors configured to determine a plurality of outlines indicating edges of the object based on two or more images captured in different directions among the one or more illumination images and the one or more pattern images; determine a virtual plane corresponding to an upper surface of the object based on the plurality of outlines; and determine an angle between the virtual plane and the reference plane.
