Summary:To provide an agricultural implement in which an object detection technology is installed for accurately and quickly detecting an object in a farm field together with a distance from a machine body.SOLUTION: An agricultural implement includes an imaging unit 9A for imaging a specified area of a farm field, a neural network 4 which inputs an imaged image from the imaging unit 9A, recognizes a specified object imaged in the imaged image, and outputs object area information indicating an area occupied by the specified object in the imaged image, a space position measuring unit 52 which images the specified area and generates object position information indicating space positions of all the objects present in the specified area, a distance calculation unit 53 which determines the space position of the specified object on the basis of the object position information and the object area information, and calculates a specified object distance being a distance to the specified object, and an object detection signal generation unit which outputs an object detection signal on the basis of the specified object distance.SELECTED DRAWING: Figure 4 【課題】圃場における物体を、機体からの距離とともに迅速かつ高精度に検出する物体検出技術を搭載した農作業機を提供すること。【解決手段】農作業機は、圃場の特定領域を撮影する撮影ユニット9Aと、撮影ユニット9Aからの撮影画像を入力して、撮影画像に写っている特定物体を認識し、当該特定物体が撮影画像において占める領域を示す物体領域情報を出力するニューラルネットワーク4と、特定領域を撮影し特定領域に存在する物体全ての空間位置を示す物体位置情報を生成する空間位置測定部52と、物体位置情報と物体領域情報とに基づいて特定物体の空間位置を決定し、特定物体までの距離である特定物体距離を算出する距離算出部53と、特定物体距離に基づいて物体検出信号を出力する物体検出信号生成部を備える。【選択図】図4
