Abstract: According to various embodiments, an electronic device include a display, an input circuit, at least one memory and at least one processor configured to obtain a first image; display, in response to cropping an area comprising a visual object corresponding to a potential vehicle appearance from the first image, fields for inputting an attribute for the area, wherein, the fields include a first field for inputting a vehicle type as the attribute and a second field for inputting a positional relationship between a subject corresponding to the potential vehicle appearance and a camera obtained the first image as the attribute; obtain information about the attribute, by receiving a user input for each of the fields including the first field and the second field through the input circuit; store a second image configured of the area in a data set for training a computer vision model for vehicle detection.

Abstract: An electronic device provided in an autonomous vehicle, the electronic device comprising a camera, a memory storing at least one instruction, and at least one processor operatively coupled with the camera, wherein the at least one processor is configured to, when the at least one instruction is executed obtain a front image in which the autonomous vehicle is driving through the camera, identify a target vehicle in the front image based on the vehicle detection model stored in the memory, generate a bounding box corresponding to the target vehicle in response to an identification of the target vehicle, generate a sliding window having a height equal to the height of the bounding box and having a width half of the width of the bounding box, divide the bounding box into a first area positioned left based on a middle position of the width of the sliding window and a second area positioned right based on the middle position, generate an extended bounding box by extending the first area in a left direction and extending the second area in a right direction, wherein size of the extended bounding box is twice as wide as size of the bounding box, obtain a sum of a pixel difference values between the first area and the second area for each shift by sequentially shifting the sliding window by a predefined pixel interval with respect to all of width of the extended bounding box, and identify a point that corresponds to a minimum value among sum values respectively indicating the sums that are obtained according to the shifting.

Abstract: An electronic device mountable in a vehicle, include a plurality of cameras disposed toward different directions of the vehicle, a memory, and a processor. The processor obtains a plurality of frames obtained by the plurality of cameras which are synchronized with each other. The processor identifies, from the plurality of frames, one or more lines included in a road in which the vehicle is disposed. The processor identifies, from the plurality of frames, one or more subjects disposed in a space adjacent to the vehicle. The processor obtains, based on the one or more lines, information for indicating locations in the space of the one or more subjects in the space. The processor stores the obtained information in the memory.
