[0002] In the cost control and management process of modern construction projects, drawing comparison is a crucial task. Traditional drawing comparison methods mostly rely on manual operation. Due to the large size of drawings, dense information, and the influence of factors such as lighting conditions and observation angles, workers are often prone to visual fatigue during long-term comparison work, and even comparison errors may occur due to slight changes in the position of drawings. In addition, the manual method of fixing drawings is difficult to effectively prevent the movement of drawings caused by touch, wind and other factors during the comparison process, which further increases the difficulty and uncertainty of the comparison work. Therefore, we propose a drawing comparison table for engineering cost drawing comparison. Utility Model Content
