Beijing Tianyuan true color 3D scanner, Tianyuan true color 3D automatic mapping technology, human body 3D scanning, 3D dynamic capture, Beijing Tianyuan true color 3D scanning system adopts advanced image texture analysis and acquisition technology, While performing three-dimensional data reconstruction, the true color display of the object surface is maintained. This technology completely retains the true color of the object being measured, and is very suitable for occasions such as digital cultural and ancient building measurement that have high requirements on texture and color. The bit-colored point cloud closely combines spatial information and object surface texture information to restore the true physical characteristics of the object to the greatest extent.
The system collects every detail with high resolution and precision and provides extremely high resolution, high-precision appearance and texture presentation, and true color representation of actual objects. True portability Fits into a suitcase, making it easy to carry to the job site or move between factories. Automatic accurate texture real-time matching automatically obtains object textures and dimensions in the same coordinate system with extremely high accuracy and achieves instant alignment, eliminating the need to perform the normally required alignment steps after scanning. Adjustable uniform texture resolution Output files display the entire model at uniform resolution from every viewing angle, a feature that is very beneficial for scanning shapes with large curvatures.
The system has the following advanced technical features
The system uses high-resolution digital industrial cameras and SLR digital cameras to collect three-dimensional point cloud and image data. Through the stripes of the light source on the surface of the object, any image can be obtained in a few seconds. The specific density of dense point clouds on complex surfaces depends on the size of the object being measured, the camera resolution and the measurement distance. The resolution used by the system ranges from 10,000 to more than 10,000 pixels, which can meet the needs of different customers. The system software is an independently developed core technology product with highly 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 conditions where strong light interferes with normal use, it has a very strong adaptability to objects with higher reflectivity, higher projection rates, and very dark objects with extremely low reflectivity, and can avoid the use of imaging agents to the greatest extent. During the operation of the software, all collected data are corrected at the sub-pixel level, which greatly improves the collection accuracy.
Reconstruction method of true color object surface.
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 and ancient building measurement that have high requirements on texture and color. The bit-colored point cloud closely combines spatial information and object surface texture information to restore the true physical characteristics of the object to the greatest extent.
Automatic splicing method.
Image data from different viewing angles are automatically combined into a unified coordinate system based on the texture of the object itself, thereby obtaining the overall scanned data of the three-dimensional image. 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 splicing methods with or 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.
System accuracy has the lowest dependence on hardware equipment
The optical calibration module of the entire system adopts 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.
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 never letting the user handle what the software can handle, so as to minimize the number of user-set parameters of the entire system. 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 the unnecessary setting work of manual participation by the user, but also makes the entire system more adaptable, has a higher degree of automation, and reduces the risk of human errors. Even less likely.
Convenient true color point cloud operation process.
The system has a flexible point cloud processing method, which not only supports basic operations such as deletion and cancellation of block display, but also can perform 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 operations such as arbitrary rotation, scaling, and local scaling of three-dimensional images.
Users can define the export file format, which is highly versatile and customizable.
The system has a wide range of data output interfaces that can be exported to other formats, and the measurement results can be edited in other common 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.
The operation interface is highly integrated, simple and easy to use, and the system has strong compatibility.
The software is powerful and has a unique fully automatic splicing module technology that does not require marking points, making the calibration process flexible and free for users to operate. 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.
