The present invention relates to a method for acquiring object information, the method comprising: a step of obtaining an input image capturing a sea; a step of obtaining a noise level of the input image; a first image processing step of when the noise level indicates a noise lower than a predetermined level, acquiring object information related to an obstacle included in the input image from the input image by using a first artificial neural network wherein the first artificial neural network outputs, from an image, object information related to at least one of a distance and a type of an object included in the image; and a second image processing step of when the noise level indicates a noise higher than the predetermined level, obtaining an image of which an environmental noise is reduced from the input image by using a second artificial neural network trained to generate, from a first image containing a noise, a second image of which a noise is reduced, and acquiring object information related to an obstacle included in the sea from the image of which the environmental noise is reduced by using the first artificial neural network, wherein the second artificial neural network is trained by using a first error calculated from a third artificial neural network discriminating the second image and an image for comparison corresponding to the first image and having a noise lower than the first image.
