Photogrammetry

A recent trend in photogrammetry is the use of unmanned aerial vehicles (UAVs) for photogrammetric purposes. A data acquisition sensor is mounted on an unmanned aerial vehicle to collect data during short-range aerial photogrammetry from a low altitude. This system is capable of filling a significant gap left by other conventional methods in the field of map production. The improvement in processes over conventional methods is the basis for this method's effectiveness. A significant portion of valuable data is obtained after the first processing stage as a result of automation in all data production processes. Real orthoimages, 3D models, and a detailed point cloud of the area are all included in this data. Drawing and mapping maps have gotten much easier, more accurate, and quicker thanks to modern software. We are looking for ways to use these kinds of methods in documenting the archaeological heritage in this article by applying this method at the historic site of Susa. The experts and practitioners in this field will benefit from this method, which is a collection of the most effective techniques for geometric measurement, analysis, and interpretations related to issues raised in archaeology.

Background : Work-related musculoskeletal disorder is the most important occupational disease that threatens the health of employees. Aim: The aim of this study was to investigate the relationship between workers' posture and musculoskeletal disorders. Materials and Methods: Eighty-two male and female workers working in a home appliance factory participated in this cross-sectional study. Musculoskeletal disorders were investigated using Nordic questionnaires. Posture evaluation was performed to measure the angles of forward head, rounded shoulders, and thoracic kyphosis using photogrammetry. Craniovertebral, shoulder, and thoracic kyphosis angles were photographed during the work and then measured using ImageJ software. Data analysis was done using SPSS 26 and Spearman's correlation test at a significance level of 0.05. Results : A significant relationship between the craniovertebral angle and musculoskeletal disorders in the last twelve months was observed in the cervical region ( P <0.001). Also, a significant relationship was observed between the kyphosis angle and musculoskeletal disorders in the last twelve months in the upper back and lower back ( P <0.001). Conclusion : The results showed that the workers’ posture during work is correlated with the prevalence of musculoskeletal disorders. Therefore, it is suggested to pay attention to ergonomic principles during work to maintain and improve the physical health of workers.
