Method, device and electronic device for detecting ripe coffee fruit

Abstract

The invention discloses a detection method, a device and an electronic device for coffee ripe fruit, wherein, the method comprises the following steps of: obtaining an image to be detected; A superpixel segmentation is carried out on that image to be detected, and a plurality of superpixel subimage are obtained; A superpixel sub-image is detected based on a coffee fruit ripening detection model todetermine that coffee ripen fruit in the superpixel sub-image; Among them, coffee fruit ripening detection model is obtained by training the supervised learning algorithm with sample images. By usingthe superpixel as the minimum unit to detect coffee ripe fruit, the superpixel segmentation can keep the shape of fruit and the signal-to-noise ratio is high, which provides a basis for the detectionof coffee ripe fruit by using the detection model of coffee ripe period. In addition, because the coffee fruit ripening detection model is obtained by training the supervised learning algorithm withsample images, it can ensure that the detection model after training has high detection accuracy, and then can achieve high accuracy of coffee ripening detection.

Description

technical field [0001] The invention relates to the cross technical field of digital image processing and agricultural meteorological observation, in particular to a method, device and electronic equipment for detecting ripe coffee fruit. Background technique [0002] Coffee is one of the three major beverages in the world. Due to the asynchronous development of coffee flower buds, coffee has the characteristics of multiple flowering and concentrated flowering. For example, in Yunnan, the full flowering period is from March to May, and each flowering lasts for about three days, so the fruiting period lasts from October to about January, which leads to different ripeness of fruits during the harvesting period and coffee fruit ripening period at different times. Difficult to track and predict in space. At the same time, the harvesting period lasts for a long time, resulting in high harvesting costs, heavy picking workload after harvesting, unfavorable for a series of problems...
