With eight advantages:
1. Using advanced sub-pixel level object surface scanning method, to meet the needs of high-quality point cloud scanning.
The system adopts a high-resolution digital industrial camera to collect image data, through the light source in the object surface streak, can be obtained within a few seconds of any complex surface of the dense point cloud (the specific density depends on the size of the object to be measured, the resolution of the camera and the measurement distance, in general the point spacing of 0.05 - 0.5mm), the system adopts a resolution of 1.3 to 5 million pixels ranging from the system, to be able to The resolution of the system ranges from 1.3 million to 5 million pixels, which can meet the needs of different customers. The system software is a self-developed core technology product with standardized interface and high efficiency, which is suitable for the development of software function expansion requirements. The sub-pixel scanning method adopted by the system can adaptively adjust the optimal position according to the local curved surface of the measured object. It has been proved in practice that this advanced sub-pixel scanning method can significantly improve the accuracy and anti-interference ability of the system, so that the scanner can be used normally under outdoor conditions (strong light interference), and has a strong adaptive ability to the objects with higher reflectance, higher projectivity, and the objects with very dark color (very low reflectance), and can be used in the maximum range of 1.3 million pixels. Strong adaptability to high reflectivity, high projectivity and very dark color objects (very low reflectivity), avoiding the use of developer to the greatest extent possible. During the operation of the software, all data collected is corrected at the sub-pixel level, which greatly improves the collection accuracy.
2. True-color object surface reconstruction method.
The system adopts advanced image texture analysis and acquisition technology to maintain the true-color display of the object surface while reconstructing the 3D data. This technology better preserves the original color of the measured object, which is very suitable for digital cultural relics, ancient architecture measurements and other occasions with high requirements for texture and color. The 24-bit color point cloud closely combines spatial information and object surface texture information to maximize the restoration of the object's true physical characteristics.
3. Fully automatic splicing method.
Image data from different viewpoints are automatically stitched together in a unified coordinate system by relying on the object's own texture, thus obtaining the overall scanning data of the 3D image. When scanning objects with rich textures, the system can complete the stitching function without pasting any reference points on the surface of the object, which greatly improves the stitching efficiency. In addition, the system also supports the reference point stitching method, which is suitable for cases where the texture characteristics of the object surface are not obvious. For the two splicing methods with or without marking points, there is no need to do any setup work in the process of acquisition and processing. This method also applies to the hybrid splicing mode where only a few markers are added. All splicing methods do not have any different expression at the user level, which fully satisfies the user's one-click splicing experience.
4. Minimal dependence on hardware devices for system accuracy
The optical calibration module of the entire system uses ultra-high precision semiconductor process products to maximize calibration accuracy. Software in the acquisition process in real-time error correction, the lens of a number of aberrations are also strictly corrective treatment, this series of complex processing to ensure that the system's overall scanning accuracy, and the optimization of the design of the correction module does not consume too much scanning time.
5. Simple system settings, easy to use
In the overall development of the scanner, adhere to the "software can handle, never let the user to deal with the" concept, so that the entire system of the user to set the number of parameters to a minimum. The scanning software will run in a more accurate way to dynamically calculate the required parameter values, not only to avoid the user manually involved in unnecessary settings, but also to make the whole system a wider range of adaptability, a higher degree of automation, the possibility of human error is lower.
6. Convenient operation process of true color point cloud.
The system has a flexible point cloud processing methods, that is, to support the deletion, cancel, block display and other basic operations, but also point cloud noise processing and trimming. Three-dimensional point cloud processing efficiency, computing speed, suitable for high-precision object scanning. The three-dimensional image to achieve arbitrary rotation, zoom, local scaling and other operations.
7. Users can define the export file format, versatility and customizability.
The system has a wide range of data output interface, can be exported to ASC, IGS, STL, OBJ, WRL and other formats, measurement results can be edited in Geomagic, 3ds Max, Catia, ProE, UG, imageware, polyworks, solidworks and other general 3D reverse software. The system supports the customized dilution function of the point cloud, which reduces the number of output point clouds and improves the software processing efficiency under the condition of meeting the accuracy.
8. The operating interface is highly integrated, simple and easy to use, and has strong system compatibility.
Software powerful, unique fully automatic splicing module technology without the need to mark points, easy to operate and use; calibration process is flexible and free, the scanning software can automatically identify the marking points, and automatically calculate the calibration results. The calibration process is flexible and free, the scanning software can identify the marking points automatically and calculate the calibration results automatically.
Five reasons:
I. High-precision color point cloud and fully automatic texture mapping solution
The Hxscan3D system captures the point cloud not only with high precision, but also preserves the color of the object surface. This makes it easier for users to identify points by their color information and complete point cloud post-processing operations, such as deleting noise and splicing multiple point clouds, eliminating the need to manipulate a single-color point cloud and giving users a whole new experience. The fully automatic texture mapping solution is exclusive at home and abroad, maximizing mapping accuracy while improving the efficiency of 3D creative work.
2. Fully automatic stitching without markers
For objects with rich textures, Hxscan3D can automatically stitch multiple point clouds based on the surface texture of the object without the aid of markers. Objects do not need to be sprayed with developer or labeled with marker points. For monochromatic or poorly textured objects, the Hxscan3D system can also use marker points to stitch the point cloud data.
These two scenarios require no configuration changes, and the point cloud stitching is done simply, quickly, and accurately.
The overall splicing correction
The overall splicing correction completely eliminates the cumulative errors during multiple acquisition and splicing, effectively suppresses the point cloud layering phenomenon, and maximizes the overall accuracy of the point cloud.
Four, high-precision calibration module
The calibration target of the system is made of ultra-high-precision e-beam technology, which ensures the high precision of 3D data.
V. Advanced sub-pixel level surface scanning method
