Embodiment Construction

[0104] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0105] With the continuous expansion of image data scale, digital image segmentation algorithms have higher and higher requirements for image processing speed and real-time performance. For some algorithms whose real-time requirements are at the millisecond level, it is difficult for traditional software platforms to complete the corresponding calculations within the specified time. Moreover, the existing technology does not combine the register resources and pipeline structure of FPG, so it cannot perform real-time segmentation of images during the growth process of field crops, and cannot greatly improve the speed of imag...
