The invention discloses a real time field depth analogy method based on fuzzy partition of a
graphics processor. The real time field depth analogy method based on the fuzzy partition of the
graphics processor comprises the following steps of (1) converting a to-be-processed image into a
file format which can be processed by a
graphics processing unit (GPU), (2)
processing specific information of the image, (3) carrying out partition blur
processing to the image according to the specific information of the image, and deciding that the image adopts different fuzzy
radius in different areas according to the specific information, and thus imitating a filed
depth effect. Due to the facts that parallelism and programmable capacity of the GPU are fully used, a scene is saved as a texture in render, and a large amount of algebraic operation is transferred from a
central processing unit (CPU) to the GPU, the real time field depth analogy method based on the fuzzy partition of the graphics processor not only releases the CPU, but also reduces amount of communication between the CPU and the GPU, and greatly improves
imitation speed of the filed depth. Due to the fact that a partition fuzzy
algorithm is directly used for processing an original image, a step of fusion of a traditional
algorithm fuzzy image and the original image is saved, and accuracy of filed depth
imitation is further improved. The image is clear and exquisite, close to a field
depth effect picture which is shot by an actual camera, and the real time field depth analogy method based on the partition blur of the graphics processor is applicable to a
virtual reality system.
