Kneel down! New technology of photogrammetry and remote sensing! Let's introduce the details! That big brother can help me solve it! Thank you very much ! !

1. The project "Core technology and products of high-precision light and small aerial remote sensing system" is a key project in the field of earth observation and navigation. Its goal is to break through the core technologies of light and small aerial remote sensing payload, high-precision POS and inertial stabilization platform, and develop four core products: high-precision light combined wide-angle digital camera, light and small airborne lidar, high-precision small POS and stabilization platform, and efficient and fast data processing system, so as to promote the industrialization development of high-precision light and small aerial remote sensing in China.

2. Aerial digital camera has become an important means to obtain photogrammetry data. With the appearance of traditional film cameras, aerial digital cameras are expected to replace traditional film aerial cameras as the main means to obtain geospatial information. Domestic digital camera SWDC-4 also occupies a certain share in the domestic market.

3. The new generation digital photogrammetry processing platform has entered the practical stage. With the rapid development of new sensors such as aerial digital camera and airborne lidar, the data acquisition of photogrammetry system has been improved unprecedentedly. The appearance of DPGrid effectively solves the bottleneck problem of massive data processing technology, greatly improves the efficiency of digital photogrammetry, and provides a solid guarantee for the rapid collection and update of three-dimensional spatial information.

4. Lidar technology has been widely used. Airborne lidar integrates laser scanner, global positioning system and inertial navigation system, and the ranging accuracy reaches centimeter level. At present, there are about 20 sets in China, which have been successfully applied to large-scale mapping, power grid design, transmission line inspection and maintenance, three-dimensional modeling and so on. The measurement speed of ground lidar has also been greatly improved, and the ranging accuracy can reach millimeter level. If fused with digital image, the texture mapping of 3D model can be completed quickly. China Academy of Surveying and Mapping successfully applied the fusion of airborne lidar, ground lidar and digital image to the 3D modeling of Dunhuang Mogao Grottoes, and achieved good results in the protection of cultural heritage.

5. Pay attention to data collection and application of mobile mapping system. The research in the field of mobile mapping in China started earlier, and now it has made breakthrough progress in multi-sensor fusion, system error comparison, traffic geographic information system and so on. LD2000 mobile measurement system has been exported to Italy, Iran and other countries.

6. Tilt photography is a high-tech developed in the field of international surveying and mapping in recent years. It was introduced into China in the first half of this year, which opened up a broader development space in the field of high-resolution urban aerial remote sensing and made new contributions to further improving the scientific and technological level of surveying and mapping in China.

In addition, the success of China's first airborne multi-band and multi-polarization interferometric SAR mapping system, the application of high-resolution satellite remote sensing images in western mapping, the maturity of small satellite constellation technology and the development of intelligent sensors, the development of China's synthetic aperture radar technology from two-dimensional to three-dimensional, and the development of image and three-dimensional map products have greatly promoted the rapid development of 3S industry. In the next few years, remote sensing technology will enter a new stage, which can provide all kinds of earth observation data quickly and timely.

In addition, there are new technologies in China recently, but I don't have relevant information. Let's communicate more. Which unit or school are you from?
