Definitions

  • the present invention relates to 3D technology, and in particular to a human body 3D photography technology.
  • 3D photography is a new term that has emerged in recent years. It refers to the use of digital three-dimensional sensors to collect 360-degree information about the human body and obtain a three-dimensional digital model of the human body. With the help of three-dimensional display technology, we can browse the three-dimensional model on a computer or mobile phone, and we can also process the three-dimensional model through "3D printing” technology to turn it into a sculpture portrait that can be viewed and touched.
  • Chinese patent CN 203708345 U discloses an instantaneous three-dimensional photography system based on a camera array, including: a camera rack, a flash, a distributed data acquisition controller and a main control computer; the camera rack includes a mounting bracket, a plurality of camera adapter plates respectively fixed on the mounting bracket, a plurality of cameras respectively fixed on each camera adapter plate and a rack controller fixed at the bottom of the mounting bracket.
  • This solution has the following shortcomings: 1. Insufficient light field, open setting will cause light to escape, and strong flash will cause uneven illumination; 2. There is no reasonable setting of structured light, which is not conducive to 3D modeling.
  • Cikon patent CN204652507U discloses a three-dimensional scanning system, including a box, a turntable mechanism, a screw rod, at least one camera assembly, several soft light sources for providing illumination, a computer and a remote control, and a battery pack for providing power.
  • the camera assembly and the soft light source are electrically connected to an external AC power supply, the computer control part is connected to the turntable mechanism, and the turntable mechanism is controlled by a remote control.
  • a three-dimensional scanning system uses an RGB-D camera, which can simultaneously collect depth and color information, and uses a 360-degree rotating turntable to truly save 360-degree information of the scanned object.
  • the camera has no visible light source, which will not cause discomfort to the scanned object, such as the human eye, and will not interfere with the color of the scanned object.
  • the shortcomings of this solution are: 1. When a person stands on the turntable, the space is small; 2. The scanning process is slow, and if the expression of the person in the middle changes, the photo will be distorted; 3. The pixel is low.
  • the purpose of the present invention is to provide a human body 3D photography studio with uniform light field distribution, high pixel, fast photography and easy installation.
  • the human body 3D photography studio of the present invention includes a control system, lighting, structured light and a 3D camera, wherein the human body 3D photography studio as a whole is a cylinder with a diameter of 3 meters, and the cylindrical frame is provided with 18 columns, and the sides, top and bottom of the cylinder are provided with low-absorption diffuse reflection shading cloth; two high-visibility finger evidence light strips are provided on the front of the column, and a high-visibility finger ambient light strip is provided on one side of the side of the column, and 5 high-speed cameras are distributed on the column, and the height of the top high-speed camera is greater than the height of a person and is set at an angle obliquely downward; structured lights are respectively provided on the four diagonally arranged columns, and the structured lights form a grid projection space with a diameter of 90 cm in the human body 3D photography studio.
  • the low-absorption diffuse reflection shading cloth is a double-sprayed cloth with a shading rate greater than 95% and an absorption rate of 2-3%.
  • the evidence light strip and the ambient light strip are high display index 5700 Kramer DC light strips, LEDs are arranged inside the light strips, and the lampshades of the light strips are light-averaging lampshades.
  • the present invention After adopting the above scheme, the present invention generates a reasonable light field through the distributed evidence light strips and ambient light strips, and the low-absorption diffuse reflection blackout cloth completely encloses the studio, so that the light from the inside will not escape and the outside light will not interfere with the photography; the all-round distributed high-speed imaging cameras can collect 1.3 billion pixels of image data in one imaging through the cloud control system and image encoding suite, which not only improves the pixels but also reduces the shooting time to within 1/4 second.

  • the human body 3D photography studio of the present invention is cylindrical with a diameter of 3 m, and its frame is composed of 18 aluminum alloy columns 1 fixedly arranged on a multi-section spliced annular base 41 at the bottom 4.
  • Low-absorption diffuse reflection shading cloths 2, 3, and 42 are arranged on the outside of the columns 1, the ceiling, and the ground.
  • the diffuse reflection shading cloth is made of double-sprayed cloth with a shading rate greater than 95% and an absorption rate of 2-3%, so that the light of the studio will not escape and the light from the outside will not interfere with the shooting.

  • the type of the ambient light light strip 14 is the same as that of the evidence light strips 12 and 13.
  • the other ambient light light strips 14 are all arranged on the left side of pillar 1. Since the studio is enclosed by low-absorption diffuse reflection blackout cloth, a more reasonable light field suitable for modeling is formed inside.
  • Three structural lights 17 (two or one structural light may be provided as technology develops) are provided on the 3rd, 8th, 12th and 17th columns (or other four diagonal columns), and the structural lights 16 are facing the head, body and legs of the person being photographed, so that the structural lights in four directions illuminate the center of the studio to form a columnar grid space with a diameter of 90 cmm.
  • Five high-speed cameras 15 and 16 are distributed on each column, and the top camera 15 is higher than the height of the human body and is set downward to photograph the head of the person.
  • a person When in use, a person (can be multiple people) stands in the columnar grid space, and four groups of structural lights project a pre-designed grid pattern on the person. Changes in the height and texture of the human body surface will cause the density of the structural light grid to change.
  • the matrix's high-speed camera shoots the human body and the grid and transmits it to the background for 3D modeling. Now, a simulated 3D portrait can be produced through model repair, mapping, and 3D printing.

Abstract

Un studio de photographie de corps humain tridimensionnel (3D), dans lequel un cadre cylindrique comprend 18 colonnes (1), et un tissu d'occultation à réflexion diffuse et à faible absorption (2, 3, 42) est disposé au niveau d'une partie latérale, d'une partie supérieure et d'une partie inférieure du cadre cylindrique ; des bandes de lumière pour analyse médico-légale (12, 13) à haut indice de rendu de couleur sont disposées sur une surface avant de chaque colonne (1), une bande de lumière ambiante (14) à haut indice de rendu de couleur est disposée sur l'une des surfaces latérales de la colonne (1), et cinq caméras à haute vitesse (15, 16) sont réparties sur la colonne (1) ; et quatre colonnes (1) agencées en diagonale sont chacune pourvues de lampes structurales (17). Les bandes de lumière pour analyse médico-légale (12, 13) distribuées et les bandes de lumière ambiante (14) génèrent un champ de lumière rationnel ; et les caméras d'imagerie à haute vitesse (15, 16) distribuées de manière omnidirectionnelle peuvent capturer des données d'image de 1,3 milliard de pixels dans une seule imagerie, ce qui permet d'augmenter la résolution et de réduire le temps de prise de vue à moins d'un quart d'une seconde.
