| Summary: | Lighting is one of the main elements in photographic process. Adequate source of lighting is required to give enough illumination to the object. Close Range Photogrammetry (CRP) is one of the technique and it has been used in variety of fields for example forensic, traffic management, archeology, medical, construction and else. These kinds of fields have different condition and environment for instance in term of source of lighting. The lack of illumination on the object can cause many problems, for example the quality of images, the accuracy of the project and more. Therefore, in this study, consumer grade digital camera is used to capture the image of an object and reconstruct the three dimensional (3D) model, under the different of intensity of light. The images were processed by using PhotoModeler Scanner and irfanView software. This software is help to generate the 3D model and histogram graph for analysis and result. For geometry evaluation, the model comparison is conducted between the model from CRP approach and laser scanning method. Lastly, the models constructed give different result depending on the intensity of light used. |
