"Frontier" scanning skills fifth

5, clever scanning stereoscopic objects

Most of the current scanners are of the CCD optical type. This type of scanner uses an optical lens to capture real-world imaging details and has a certain depth of field. Therefore, with this scanner, the focal length of the CCD lens can be scanned without exceeding it. The physical scope. In addition, the physical object that needs to be scanned must also meet two conditions. First, its volume should not be too large, otherwise it will affect the depth of field of the scan; in addition, the physical object cannot be too heavy, otherwise the flat glass of the scanner can easily be crushed. of. When scanning a solid object, physical objects should be placed on the top of the flat glass as much as possible. The physical object must be clearly imaged and must be placed downward on the flat glass; then, carefully cover the scan top cover with the stereo. In reality, if the volume of the three-dimensional object is relatively large, the top cover of the scanner needs to be removed, and then the background of the three-dimensional object is covered with a suitable size background fabric, so that the influence of the surrounding light on the scanning effect can be avoided. Make sure the scan is clearly visible. It should be noted here that the entire flat glass area cannot be completely covered, which will result in a wrinkled, blurring effect on the resulting image. After doing the above preparations, you can execute the scan command. Then you can select the required scan area according to the warm-up display effect, and perform a final scan of the physical object to complete the three-dimensional physical scan task.
