When using a white light scanner or a fringe projection system to perform 3D data acquisition on an object, the following sequence should be followed: After the 3D scanner, the measuring object, and the setting of the rotary table or robot required for automatic acquisition in this example are completed, the sensor should be handled. The component (camera, projector) is calibrated. Subsequently, digital measurements of the execution object are performed. For this purpose, a projector is used to project a series of striped patterns on the measurement object (in this case, Gray code and phase shift technique), so that each object displays an independent stripe shape conforming to its outline features. The camera of the system collects projected fringe patterns within a preset measurement range, and each projection differs depending on the measuring range of the object or even the object. Depending on the type of application, it may be necessary to use one or two cameras. If necessary, a rotary table or robot synchronized with the measurement process can also be added to fully automate 3D digitization. Each sequential measurement step can be completed in about one second, and the entire measurement process depends on the complexity of the measurement object, ranging from a few seconds to several minutes. Once the measured object is completely digitized, the measurement process is completed immediately, that is, each image on all sides of the object has been collected and automatically saved. Within a few seconds, the computer can calculate the 3D data of the measurement object by referencing the corresponding object geometry or aligning the individual acquisitions with the markers attached to the object before the data acquisition. The initial result is a point cloud, which is then transformed into a sparse triangular network, also known as a "grid," based on the situation of a measurement task at hand (such as reverse engineering, rapid prototyping) and a corresponding dedicated program. In this process step, the surface can be smoothed, measurement noise reduced, and data volume reduced, but overall data quality is not reduced. The accurate 3D copy model of a measurement object is a data set with different formats and can be further used for any other type of processing, such as using a CAD/CAM program. White light scanners range from a few millimeters to a meter. However, using the method described above in conjunction with another measurement method (photogrammetry) can significantly increase the area of free-form area acquisition and achieve the highest image detail. The application of three-dimensional digitization is very wide, ranging from injectors up to a few meters high.
3D scanning: Laser or fringe projection?
The wide market for 3D measurement and digitizing systems reflects the diversity of 3D measurement and digitization technologies. Its applications include numerous laser scanners and fringe projection systems (or white light scanners). These devices can be used for both static and dynamic measurements. . However, it is important to understand the basic differences between the two systems in data accuracy, application areas, and measurement processes. The laser scanner can collect independent measurement points, measurement lines that make up a polygon, and a small measurement point grid area. The fringe projection system can only measure the entire surface of the object. The high measurement point density not only enables more accurate area measurement data, but also enables higher resolution. Unlike laser scanners, the latter can eliminate time-consuming pre-processing of measurement objects, such as pasting and correcting reference marks, or spraying delusterants on bright surfaces. The fringe projection system is best suited for measurements in enclosed rooms where environmental conditions (such as temperature, light) can be controlled. The fringe projection system uses precise, high-quality hardware components to obtain reliable measurement results at extremely high or low temperature conditions, and can also be adjusted for environmental conditions during measurement (for example, using a sun visor or at night Scanning) Thanks to the above factors, this type of 3D scanning system also enables reliable outdoor measurements. In addition, compared with high-end laser scanners, the white-light scanner's data quality (measuring accuracy up to submillimeter range), resolution, and ease of operation can all be greatly improved. In addition, the system also has a high degree of flexibility. Regardless of the complexity of the project, this three-dimensional measurement and digitization system can be easily adjusted in the field of multi-dimensional modern 3D object measurement and digitization (eg, from reverse engineering to inspection) by adopting appropriate hardware and software configurations and expansion schemes. Perfectly handle various types of tasks to meet the increasingly demanding project requirements of customers.
