If the analysis of the dried rose petal color is to use the YCrCb color model, since this model is a color representation model designed for digital video conversion (Y represents the brightness of the light source, and the chromaticity information is combined in Cr and Cb, and Cr represents the light source The red component in the light source, Cb represents the blue component in the light source), so there are two shortcomings: one is that the green information of the object is not easy to obtain, and the other is that the instrument is expensive and difficult to use

Embodiment Construction
[0011] Such as figure 1 Shown, the method of the present invention comprises according to the computing flow of camera, RGB extraction module, computing module and judging module; figure 2 Shown is the image sampling device of the present invention, which includes a dark box 2 and an image acquisition hole 1 thereon, and the image acquisition hole is arranged on one surface of the dark box. The camera is placed in the image acquisition hole 1 in the dark box and fixed (because the RGB value is easily affected by the external light intensity, in order to reduce the impact of this error on the system, the dark box is used to isolate the camera environment from the outside world). Put the rose petals in the image acquisition camera device, the rose petals cover the entire background of the image, the camera is 80-90mm away from the rose petals; the camera has its own LED light source, the precision is not less than 2 million pixels, and the lens is placed in the image acquisitio...

The present invention provides a detecting method for identifying the drying quality of rose through color identification. The roseleaf is arranged in an image collection camera device. The image collection information is inputted into an RGB extraction module which outputs the extracted color numerical value to a calculating module. The calculating module outputs the calculation result to a determining module and finally the drying degree of the rose is determined. Through the analysis to the component of pigment in the roseleaf, whether the drying quality is qualified is determined thereby searching an optimum drying temperature. The invention is a method with the advantages of low cost and easy realization.
Description
technical field [0001] The invention relates to the technical field of agricultural product detection, in particular to a detection method for identifying the dried quality of roses by color. Background technique [0002] During the drying process of rose petals, the drying method and parameters play a key role in the drying quality of rose petals. The temperature, humidity and dehumidification during the drying process are the main factors affecting the quality of rose petal dried products with color as the main symbol. The drying temperature should not be too high, otherwise there will be more loss of nutrients, but if the drying temperature is not high and the moisture cannot be removed in time, the rose petals will be mildewed, resulting in a decline in drying quality. The method of evaluating the drying quality is mainly based on judging the color of the dried rose petals. If human sensory judgment is used, it will inevitably have a lot of subjective randomness. For t...
