To provide a work state analysis system and a work state analysis method which can automatically determine whether or not a work by a worker is appropriate while reducing a data volume to be handled.SOLUTION: In a work state analysis system 1, a communication device 21 acquires captured data obtained by capturing a work state of a worker. A processing device 22 has a work estimation model constructed by inputting a still picture obtained by capturing works by the worker and the works shown by the still picture as teacher data to perform machine learning, inputs the still picture based on the captured data into the work estimation model to estimate the works shown by each still picture, and creates first work estimation data in which estimation results of the works are chronologically arranged. The estimation results are further corrected so that the estimation results of the same works continue to the first work estimation data to create second work estimation data, and the order of the works is estimated on the basis of the created second work estimation data. Then, it is determined whether or not the order of the works performed by the worker is appropriate on the basis of the estimated order of the works.SELECTED DRAWING: Figure 1 【課題】取扱うデータ量を抑えつつ、作業者の作業が適切か否かを自動的に判定可能な作業状況分析システム及び作業状況分析方法を提供する。【解決手段】作業状況分析システム１において、通信装置２１は、作業者の作業状況を撮影した撮影データを取得する。処理装置２２は、作業者の作業を撮影した静止画と当該静止画が示す作業を教師データとして入力して機械学習を行って構築された作業推定モデルを有し、撮影データに基づく静止画を作業推定モデルに入力してそれぞれの静止画が示す作業を推定し、作業の推定結果を時系列で並べた第１作業推定データを作成する。さらに、第１作業推定データに対して、同じ作業の推定結果が連続するように推定結果を修正して第２作業推定データを作成し、作成した第２作業推定データに基づいて作業の順序を推定する。そして、推定した作業の順序に基づき、作業者が行った作業の順序が適切か否かを判定する。【選択図】図１
