Since 4DAGE was founded in 2014, it has been dedicated to the studies and application of artificial intelligence in the field of three-dimensional digital reconstruction. With the vision of "digital everything", it is bringing digital technologies to the everyday life of common people.4DAGE is one of the first 3D digital reconstruction centers in China, and one of the pioneer domestic companies to provide 3D display technologies. It has developed the proprietary technology of precise 3D digital scanning and reconstruction, the accuracy of which is improved to micron scale, and the efficiency of which is 200 times higher than traditional 3D reconstruction methods, outstripping the centimeter-scale precision achieved by Adobe Systems in the US. Only two organizations meet the requirement of such accuracy--one is 4DAGE; the other is the MIT computer vision laboratory. 4DAGE provides products and solutions not only for major museums and expositions at home and abroad, namely the Palace Museum, Nanchang Han Dynasty Haihunhou Historic Site Museum, World Expo, etc., but also significant national projects such as the virtual reality reconstruction for Hong Kong-Zhuhai-Macao Bridge. It serves industries ranging from industrial intelligence and smart city, to real estates and new retail.
