...Jialiu Chen; Yunzhong Cao Purpose The construction industry faces challenges such as high safety risks and a lack of effective technical means for safety management. In complex low-light scenes, achieving accurate and efficient object detection is a key issue for improving construction safety...

... an innovative approach for excavator recognition based on computer vision technology tailored for night scenes. Design/methodology/approach The proposed approach consists of two modules: an object detection module and an image lighting enhancement module. You Only Look Once version 7 (YOLOv7) is applied...

... of the appearance quality of precast components in the prefabricated construction process through digital means. Design/methodology/approach The paper begins by establishing an improved YOLO model and an image dataset for evaluating appearance quality. Through object detection in the images, a preliminary...

... simultaneously; establishing a connection between workers and their behaviors. Design/methodology/approach Taking a reinforcement processing area as a research case, a new method for recognizing each different worker's activity through the position relationship of objects detected by Faster R-CNN is proposed...
