The Terracotta Warriors and Horses of Qin Shihuang are one of the greatest discoveries in the world's archaeological history, and they are known as the "eighth wonder of the world". The client hopes to build a three-dimensional digital model of the terracotta warriors and horses sculptures, and quickly form a scaled terracotta warriors and horses sculpture models.

Practical problems

1. Terracotta warriors and horses sculptures have complex character expressions and movements, as well as subtle patterns and textures. It is difficult for general 3D scanners to obtain complete 3D data.

2. Using traditional measurement methods, only part of the data of the terracotta warriors and horses sculptures can be obtained, and some small textures cannot be measured, resulting in incomplete data volume, and it is impossible to establish a three-dimensional digital model of the terracotta warriors and horses sculptures.

According to the requirements of the staff and the actual situation, Hualang 3D engineers use 3D scanner HL-3DS (high-efficiency and high-precision acquisition of 3D data of terracotta warriors and horses) + reverse design software Geomagic Studio to build a database of terracotta warriors and horses sculptures.

Holon3d Engineer 3D Scanner HL-3DS scans the terracotta sculptures more than 1 meter high (it only takes 20 minutes to obtain the complete 3D data of the terracotta warriors) and high precision (the accuracy of the 3D data of the terracotta warriors and horses reaches 0.03mm). Whether it's complex character expressions and movements, or subtle pattern textures, the three-dimensional scanner HL-3DS can clearly collect and display all data, with a minimum dot pitch of up to 0.047mm.

The three-dimensional digital model of the sculpture is established through the three-dimensional scanning of the terracotta warriors and horses sculptures. After the database of the sculptures is established, the terracotta warriors and horses sculpture models of the same proportion are reproduced by CNC block casting and rapid prototyping, and the mold shell is rebuilt, and after the resin mold shell is made Then the copper water is poured, and after the copper water cools, the shell is broken and the bronze sculpture is completed (for block casting, welding and assembly are required).
