The rotation of the sixth housing 55 drives the fifth driven bevel gear 56 around the third driven bevel gear 56. The fifth active bevel gear 54 rotates, the fifth driven bevel gear 56 rotates to drive the fourth rotating rod 57 to rotate, the fourth rotating rod 57 rotates to drive the sixth active bevel gear 58 to rotate, the sixth active bevel gear 58 rotates to drive the sixth driven bevel gear 61 to rotate, the sixth driven bevel gear 61 rotates to drive the fifth rotating rod 62 to rotate, the fifth rotating rod 62 rotates to drive the seventh housing 60 to rotate with the fifth rotating rod 62 as the center, so that the camera mechanism on the sixth housing 55 and the seventh housing 60 is adapted to the human head of different body shapes. When the adjustment is completed, the third active bevel gear 39 moves upward and separates from the third driven bevel gear 40. Under the action of the second spring 67, the third rack 42 and the third driven bevel gear 40 are meshed with each other;At this time, when the human body is to be photographed in all directions, the second motor 8 is started, and the second motor 8 rotates to drive the fourth housing 10 to rotate. The fourth housing 10 rotates to drive the first rotating rod 22 to rotate with the first rotating shaft 43 as the center. The first rotating rod 22 rotates to drive the first driven bevel gear 31. Because the first active bevel gear 30 remains stationary under the action of the first sleeve 29, the first driven bevel gear 31 rotates around the first active bevel gear 30 with the first rotating rod 22 as the center. The rotation of the first rotating rod 22 drives the first sleeve 23 to rotate. The rotation of the first sleeve 23 drives the third gear 18 to rotate. Under the action of the third gear 18 and the first rack 14, the reciprocating member 19 moves. The movement of the reciprocating member 19 drives the reciprocating rod 11 to move. The movement of the reciprocating rod 11 drives the camera mechanism to move. At this time, the camera mechanism rotates with the first rotating shaft 43 and reciprocates up and down, thereby realizing the need to photograph the human body in all directions. The purpose of video recording; when the scanning mechanism scans and models the human body, the light strip 50 provides sufficient light source for the high-definition camera 51, and at the same time, the reflector 65 on the reflective vest 64 can reflect the special light source emitted by the light strip 50 and reflect it back in the form of parallel light. The high-definition camera 51 and the reflector 65 work together to detect the distance between the high-definition camera 51 and the human body in real time, thereby realizing accurate modeling of the human body; then the control cabinet 2 transmits the scanned data to the information processing cabinet 3, the information processing cabinet 3 analyzes and models the obtained data, and the display screen 4 displays the constructed virtual digital human, wherein the display screen 4 is a semicircular curved screen, making the virtual digital human more realistic. When people communicate with the virtual digital human, their voices are received through the digital human display cabinet, and at the same time, their voices are processed to generate smooth, clear and emotional voices close to human level for different emotions and transmit them through the digital human display cabinet 1. ;
