Embodiment Construction
[0048] Below in conjunction with accompanying drawing, structural principle and working principle of the present invention are specifically described:
[0049] see figure 1 and figure 2 , figure 1 It is a schematic diagram of the detection principle of an embodiment of the present invention, figure 2 It is a flow chart of the detection method according to an embodiment of the present invention. The hyperspectral imaging detection method for detecting male and female fragrant pears of the present invention detects fragrant pears based on stone cell content and calyx roundness and classifies them as male fragrant pears or female fragrant pears, comprising the following steps:
[0050] Step S100, collect information, collect the hyperspectral information of the fragrant pear to be tested by a hyperspectral imager, and extract the spectral information and image information of the fragrant pear to be tested, preferably the image background adopts a black background, and the fr...

The invention discloses a hyperspectral imaging detection method and device for detecting male and female bergamot pears. The method comprises the steps of collecting information, collecting hyperspectral information of the to-be-detected bergamot pear through a hyperspectral imager, and extracting spectral information and image information; calculating the bergamot pear lithocyte content, receiving the spectral information, and inputting the spectral information into a hyperspectral prediction model of the bergamot pear lithocyte content to obtain a predicted value of the bergamot pear lithocyte content of the to-be-detected bergamot; calculating the calyx roundness of the bergamot pear, receiving the image information, and obtaining the calyx roundness of the bergamot pear by use of a calyx characteristic region extraction and roundness calculation algorithm; and detecting the male and female bergamot pear, receiving the predicted value of the bergamot pear lithocyte content and thecalyx roundness, and inputting the predicted value of the bergamot pear lithocyte content and the calyx roundness into a trained linear support vector machine to classify the male and female bergamotpear to obtain the detection result of the male pear or the female pear. The invention further discloses a detection device using the above detection method.
Description
technical field [0001] The invention relates to the field of non-destructive testing of agricultural products, in particular to a hyperspectral imaging detection method and device for detecting male and female pears based on stone cell content and calyx roundness. Background technique [0002] Korla fragrant pear is a famous and high-quality special product in the west. It has a strong regional production and enjoys a high reputation and popularity in domestic and foreign markets. According to the statistics of Korla Fragrant Pear Research Center, the annual planting area of Korla Fragrant Pear is more than 1 million mu, and the total annual output of fragrant pear is about 850,000 tons. Commercially available Korla fragrant pears are usually divided into female pears and male pears, among which female pears have a good taste and a high price. The characteristics of the female pear are: the sepals fall off, most of the calyx ends are sunken, the fleshy nuclei are small, t...
