[0002] With the healthy development of cities, high-quality construction has become increasingly important. After the road construction in coastal areas is completed, in order to make the road color coordinated with the seaside scenery and enhance the comfortable experience of pedestrians, it is usually necessary to spray a layer of colored paint on the sidewalk to enhance the visual effect and form a unified color tone with the surrounding sea color. However, the traditional construction method is to directly spray on the road surface with a spraying device held manually by workers. Due to the influence of uncontrollable human factors, the spraying effect is often not good. There are differences in the spraying angle, spraying height, and spraying time of different operators, and these factors will significantly affect the final spraying effect, resulting in uneven dark and light areas on the road surface, making it difficult to achieve the initial design expectations and unable to meet the requirements of high-quality construction.
