[0022] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and examples.
[0023] Farmland information collection and processing system: such as figure 1 , 2 , 4, using CCD camera 15, DSP processor 2 containing video decoding chip SAA7111, CPLD, high-speed readable and writable memory SDRAM and buffer to complete image acquisition and processing.
[0024] Gather a frame of PAL video image in the field by CCD camera 15, utilize the video decoding chip SAA7114 that DSP processor 2 is carried to convert analog video data into digital video data, store image data in SDRAM by CPLD, DSP processor 2. Perform algorithmic processing on the collected images. In terms of algorithm design, the super green feature and the maximum inter-class variance method are used to segment the background; the shape feature, skeleton feature and planting information of the crop are fused to identify crops and weeds. Then deter...
