• How many cameras should be used for shooting (a camera rig / several cameras OR a single camera)? For a full-body capturing scenario, we advise using a camera rig, i. e. several cameras that will take images simultaneously. We recommend using several synchronized cameras since a person during the shooting process cannot maintain absolutely the same position for a long time. Human movements cause additional noise in the point cloud and they are detected as false matches during the alignment process, which eventually affects the quality of the 3D model.



  • What's the best way to shoot if I have only one camera? Move the camera along the spiral or circular tracks, providing the necessary overlap and paying special attention to the "potentially blind" spots (hands, ears, nose, clothing details).


           

  • Each photo should effectively use the frame size: the object of interest should take up the maximum proportion of the image possible. In some cases, the portrait camera orientation option should be considered.
  • Lighting. Good lighting is required to achieve a better quality of results. Blinks should be avoided during the shooting process. We recommend using a scattered light source. It is also advisable to remove sources of light from the camera field of view. 
  • Background. The object should be clearly visible against the background. We recommend choosing a background contrasting with the colors of the object: if the object itself is light, then it is better to choose a darker background (but not completely black); if the object is dark, then the background should be light. Blinks from the background on the object surface should be avoided. 
  • Object specifics:
    • Hair is difficult for reconstruction - using a well-textured hat (for example, a knitted one) is recommended. 
    • It is highly recommended for the model to avoid wearing light-absorbing (black), monotonous (without texture/pattern), reflective clothing. Materials with distinguishable and irregular patterns are preferred, e.g. knitting, jeans, etc.
    • Ask the model to put off the glasses if it is applicable.
