Have you ever considered Tianjin Huixin 3D scanner? The measured accuracy after fully automatic splicing is within an error of 0.02MM. Of course, this is laboratory accuracy. The actual operation is larger. The single frame accuracy can reach several μ. The price/performance ratio is good, ranging from tens of thousands to more than 200,000. Generally speaking, The streamlined version, which costs tens of thousands, can handle most of the work of mold processing companies. It is independently developed and has national patent and intellectual property certification.
It has eight major advantages:
1. Adopts advanced sub-pixel level object surface scanning method to meet the needs of high-quality point cloud scanning.
The system uses high-resolution digital industrial cameras to collect image data. Through the stripes of the light source on the surface of the object, a dense point cloud of any complex surface can be obtained in a few seconds (the specific density depends on the size of the object being measured and the camera Depends on the resolution and measurement distance, generally the point pitch is 0.05 - 0.5mm). The resolution used by the system ranges from 1.3 million to 5 million pixels, which can meet the needs of different customers. The system software is an independently developed core technology product with standardized interfaces and high efficiency, which is suitable for the development of expanded software functions. The sub-pixel scanning method used by the system can adaptively adjust the optimal position according to the local curved surface of the measured object. Practice has proven that this advanced sub-pixel scanning method can significantly improve the accuracy and anti-interference ability of the system, allowing the scanner to be used outdoors. Under normal use conditions (strong light interference), it has very strong adaptability to objects with higher reflectivity, higher projection rate and objects with very dark colors (extremely low reflectivity), and can avoid developers to the greatest extent of use. During the operation of the software, all collected data are corrected at the sub-pixel level, which greatly improves the collection accuracy.
2. True color object surface reconstruction method.
The system uses advanced image texture analysis and acquisition technology to reconstruct three-dimensional data while maintaining true color display on the object surface. This technology better retains the true color of the object being measured, and is very suitable for occasions such as digital cultural relics and ancient building measurement that have high requirements on texture and color. The 24-bit color point cloud closely combines spatial information and object surface texture information to restore the true physical characteristics of the object to the greatest extent.
3. Fully automatic splicing method.
Image data from different viewing angles are automatically combined in a unified coordinate system based on the texture of the object itself, thereby obtaining overall three-dimensional image scanning data. When scanning objects with rich textures, the system can complete the splicing function without pasting any reference points on the surface of the object, greatly improving the splicing efficiency. In addition, the system also supports the reference point splicing method. This technology is suitable for situations where the surface texture features of the measured object are not obvious. For the two splicing methods with and without marker points, no setting work is required during collection and processing. This method is also applicable to the hybrid splicing mode that only adds a small number of marker points. All splicing methods have no different expressions at the user level, fully satisfying the user's one-click splicing experience.
4. System accuracy has the lowest dependence on hardware equipment
The optical calibration module of the entire system uses ultra-high-precision semiconductor process products, which maximizes the calibration accuracy. The software performs error correction in real time during the acquisition process, and also strictly corrects multiple distortions of the lens. This series of complex processing processes ensures the overall scanning accuracy of the system, and there are not too many optimized and designed correction modules. Scan time is consumed.
5. The system is simple to set up and easy to use.
In the overall development process of the scanner, we adhere to the concept of "what the software can handle, never let the user handle it", making the entire system The number of user-configurable parameters is reduced to a minimum. During the running period of the scanning software, the required parameter values ??will be dynamically calculated in a more accurate manner, which not only avoids unnecessary manual setting work by the user, but also makes the entire system more adaptable, more automated, and less prone to human errors. Even less likely.
6. Convenient true color point cloud operation process.
The system has a flexible point cloud processing method, which supports basic operations such as deletion, cancellation, and block display, as well as point cloud noise processing and trimming. The three-dimensional point cloud has high processing efficiency and fast computing speed, and is suitable for high-precision object scanning. Implement arbitrary rotation, scaling, local scaling and other operations on three-dimensional images.
7. Users can define the export file format, which is highly versatile and customizable.
The system has a wide range of data output interfaces and can export ASC, IGS, STL, OBJ, WRL and other formats. The measurement results can be exported to Geomagic, 3ds Max, Catia, ProE, UG, imageware, polyworks, solidworks, etc. Edit in general 3D reverse engineering software. The system supports the custom thinning function of point clouds, which can reduce the number of output point clouds and improve software processing efficiency while ensuring accuracy.
8. The operation interface is highly integrated, simple and easy to use, and has strong system compatibility.
The software is powerful, and its unique fully automatic splicing module technology that does not require marking points is convenient for users to operate. The calibration process is flexible and free, and the scanning software can automatically identify marking points and automatically calculate the calibration results. It is easy for users to learn and use, and can be operated skillfully without excessive training.
Five reasons:
1. High-precision color point cloud and fully automatic texture mapping solution
The point cloud collected by the Hxscan3D system not only has high accuracy, but also retains The color of an object's surface. While truly digitally displaying objects, it is more convenient for users to identify points through color information and complete post-processing of point clouds, such as deleting noise points and splicing multiple groups of point clouds. It eliminates the trouble of operating single-color point clouds and gives users a new experience. Exclusively launches a fully automatic texture mapping solution at home and abroad to maximize the accuracy of mapping while improving the efficiency of 3D creative work.
2. Fully automatic marker-less point stitching
For objects with rich textures, the Hxscan3D system can automatically stitch multiple sets of points based on the texture of the object surface without the assistance of marker points. cloud. The object does not need to be sprayed with developer or labeled with marking points. For objects with a single color or low texture, the Hxscan3D system can also use marker points to stitch point cloud data.
In the above two cases, there is no need to modify any configuration, and point cloud splicing can be completed simply, quickly and accurately.
3. Overall stitching correction
The overall stitching correction completely eliminates the accumulated errors in the process of multiple acquisitions and stitching, effectively suppresses the stratification of point clouds, and maximizes the quality of point clouds. Overall accuracy.
IV. High-precision calibration module
The calibration target of the system is made using ultra-high-precision electron beam technology to ensure the high accuracy of three-dimensional data.
5. Advanced sub-pixel surface scanning method
The sub-pixel scanning method performs adaptive position adjustment according to the object surface to improve accuracy and the system's anti-interference ability. The system can be used normally under outdoor conditions or under strong light interference. It has very strong adaptability to objects with high reflectivity, high transmittance, and dark colors, and can avoid the use of imaging agents to the greatest extent.
