Agricultural system
A quality measurement system includes a first camera, a second camera, a display device, and a controller. The controller is configured or programmed to control the first camera to acquire a first image that includes agricultural items and to determine, from the first image, one of the agricultural items that is suitable for measuring quality. The controller is configured or programmed to control the second camera to acquire measurement data of the one of the agricultural items. The controller is configured or programmed to store estimation models for calculating at least one quality score based upon the measurement data acquired by the second camera and to select one of the estimation models according to the one of the agricultural items. The controller is configured or programmed to calculate the at least one quality score of the one of the agricultural items based upon the selected one of the estimation models.
