Abstract

The invention discloses a photographing system and method for automatically obtaining the transparency of an object. The system comprises a control module, a background module and an image acquisition module, wherein the control module generates an instruction according to the logic and time sequence of an automatic photographing method based on the user operation so as to control the background module and the image acquisition module; the background module automatically generates different backgrounds according to the instruction of the control module; and the image acquisition module automatically acquires object pictures in different backgrounds according to the instruction of the control module. The method comprises the following steps of: fixing an object in front of the background module; operating the control module and starting a photographing flow; sending an instruction to the background module and generating a background A; sending an instruction to the image acquisition module and obtaining an object picture in the background A; sending an instruction to the background module and generating a background B; sending an instruction to the image acquisition module and obtaining an object picture in the background B; and finally, performing digital processing on the object pictures in different backgrounds so as to obtain the transparency information and color information of the object. The system and method disclosed by the invention can automatically and actually obtain the transparency information and color information of the object.

Description

technical field

[0001] The invention belongs to the technical field of digital photographing, and in particular relates to a photographing system and method for automatically obtaining the transparency of an object. Background technique

[0002] Color and transparency are important visual properties of objects. Object pictures can only truly display objects if they retain color and transparency information intact.

[0003] Object pictures obtained by current photographing methods inevitably contain backgrounds. In the area covered by the object, if it is a transparent object, the background color will be mixed with the object color through the object, and will be captured by the camera tool together, causing the object and the background to be mixed together. Areas not covered by the object are completely background color.

[0004] In order to obtain the transparency information of the object, the current conventional method is: place the object on a background of a fixed...

Embodiment Construction

[0041] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0042] Such as figure 1 As shown, the system for automatically obtaining transparency includes a control module 101, a background module 106, and an image acquisition module 107, wherein:

[0043] The control module 101 is a central control device installed with an automatic photographing program. The control module generates control commands according to the logic and timing of successively collecting two object pictures in different backgrounds, and sends them to the background module and the image acquisition module respectively to control their execution. different actions.

[0044] At the same time, the control module 101 reads and stores the object picture captured by the image acquisition module, judges and processes it according to the image processing algorithm, obtains two pictures with the best effect under different backg...
