The invention discloses a metering detection method and device for agricultural product production, and belongs to the technical field of agricultural product production, and the metering detection method for agricultural product production comprises the following steps: S1, adjusting the shutter of a camera to be 1 / 520 s, and collecting 66 frames of clear background images through connection at a frame speed of 22 FPS in an illumination environment of a CCFL light source; s2, carrying out gray processing on the collected background image; and S3, evaluating the quality of gray level image processing by adopting a fitness function, and showing that the image enhancement effect is better when the fitness value is larger. According to the method, in agricultural product production, redundant points existing in damage feature detection through a conventional multi-scale angular point algorithm are removed by obtaining the proportion of the seeds with cracks in the sample, the seed damage feature positioning accuracy under multiple scales is effectively improved, the time complexity of iterative calculation is reduced, and through effective metering detection, the seed damage feature positioning accuracy under multiple scales is improved. The germination rate of sample seeds can be determined.
Description
technical field [0001] The invention belongs to the technical field of agricultural product production, and in particular relates to a measurement detection method and device for agricultural product production. Background technique [0002] The quality of the seeds of the crops needs to be tested before they are planted, as disclosed in the Chinese patent "a device for detecting the quality of wheat seeds and its method" (Patent No.: CN111595713A). The technical problem solved by this patent is that seeds are agricultural production Indispensable means of production, the quality of seeds is directly related to the development of agricultural production and economy, and the quality of seeds also determines the germination rate and other issues. In order to ensure the quality of seeds and the continuous improvement of seed quality, farmers To ensure the germination rate in the planting process, the seeds need to be sampled and inspected. The existing detection method is throu...
