Beijing Tianyuan 3D Photogrammetry System is jointly developed by Beijing Tianyuan 3D Technology Co., Ltd. and Tsinghua University. It was officially launched in 2016 and is China’s first independently developed optical 3D scanning and online measurement and detection system for large objects. Including close-range industrial three-dimensional photogrammetry system, surface scanning system, deformation measurement and analysis system, etc. This system has been widely used in the design, production, testing and protection of automobile molds and automobile shapes, as well as large cultural relics and Buddha statues, and has been used in many related automobile mold designs in China. There are a large number of cases for promotion and application by enterprises/car body design enterprises/oversized cultural relics and Buddha statue units for reference. This system has improved the overall technical level of China's automobile industry and the field of large-scale cultural relics protection.
Composition of one-dimensional photogrammetry system
System measurement software System measurement software is installed on a high-performance desktop or laptop computer.
A code point consists of a central point and surrounding ring codes. Each point has its own number.
Chi points are used to obtain the three-dimensional coordinates of the relevant parts of the measured object.
Industrial digital camera A high-resolution industrial digital camera with fixed focal length and interchangeable lenses.
Precision Measurement Scales Scales serve as scales for measurements, with extremely precise measured reference points to determine their lengths.

Dimensional accuracy
Tianyuan 3D photogrammetry system is the leader among similar products at home and abroad. It has high accuracy and can be used alone. Complete inspection tasks of various large sizes.
Paste specific coded reference points on the object before measurement. During measurement, use a high-resolution digital camera to take photos of the object from different angles. The resulting series of photos can be solved by relevant software to obtain the accuracy of these reference points. The spatial coordinate remote three-dimensional photogrammetry system is used to measure key points of large or very large objects ranging from several meters to tens of meters. Compared with traditional three-dimensional coordinate measuring instruments, there is no mechanical stroke limit, and it is not limited by the size and shape of the measured object. It can effectively reduce cumulative errors and improve the measurement accuracy of the overall three-dimensional data. The system can be used alone or in conjunction with the Tianyuan series of 3D camera scanners, which can effectively ensure the overall point cloud splicing accuracy of large objects.
For example
Car mold foam mold inspection can quickly detect the quality of large foam molds.
Turning mold casting inspection can quickly detect the quality of large castings, improve the efficiency of CNC machining, and avoid tool damage.
Three-dimensional inspection of parts can quickly detect the three-dimensional quality of mold parts.
Tool detection quickly detects the processing quality of mold surfaces.
The tool's closed-loop system improves the efficiency and accuracy of the mold system through rapid three-dimensional sheet metal deformation analysis, turning the traditional open-loop system into a closed-loop system, achieving a major change in the mold.
Digital grinding uses an optical three-dimensional measurement system to replace the traditional mold grinding process to achieve digital grinding and solve the problems of mold rebound and instability.
Pre-assembled and manufactured virtual assembly and virtual manufacturing are realized by digitizing the three-dimensional entities of each part.

In the process of three-dimensional measurement of large or very large objects, the Beijing Tianyuan three-dimensional photogrammetry system can be used to carry out three-dimensional photography very conveniently, quickly and flexibly. Measurement, because there is no mechanical stroke limit of the traditional three-dimensional coordinate measuring instrument, it is not limited by the size, volume and shape of the measured object, which can effectively reduce the cumulative error and improve the measurement accuracy of the overall three-dimensional data.
The three-dimensional photogrammetry system is mainly used in the following fields
To measure the three-dimensional coordinates of coding points and landmark points on the surface of objects, and to cooperate with Tianyuan three-dimensional scanner to quickly obtain high-precision three-dimensional data of very large objects
By comparing the three-dimensional geometric shape of the tested workpiece with the design drawing, the product appearance quality of large workpieces can be quickly and easily inspected
