For photo clarity and exposure, it is best to choose a SLR or a camera with high pixel, and it is not recommended to use a mobile phone. Although the pixels of mobile phones are now high, most mobile phones are not well exposed by non-professionals when shooting. The focusing function (non-mechanical zoom) of the mobile phone is basically useless, and it is not clear after zooming in. Because of shooting habits, photos are sometimes horizontal and sometimes vertical, and it is generally better to shoot horizontally. The photo size should not be too small, generally controlled at 5-8MB, which is convenient for saving and later editing.
Characteristics of construction image data:
Intuitive and timely; Has the characteristics of long-term preservation and simple operation; Comparison and traceability; It is an important means of project management.
Classification of construction image data:
Original state, concealed works, materials and mechanical equipment, construction technology, construction quality and safety control, standardized display and publicity of construction.
The image data must be clear, and the shooting angle and method should fully reflect the quality of the accepted parts and be representative. After shooting, the image data should be kept for a certain period of time for inspection. In the process of saving, we should pay attention to the following points: (1) When shooting, we should take more photos appropriately, and choose clear and accurate images to save;
When saving, the image data should be classified and sorted, and a brief description should be written; The image data should be stored corresponding to the construction data, which can reflect the actual situation on site more objectively and accurately; You can also make photos into CDs for storage, which is more conducive to the preservation of information.
