Abstract
A harvesting apparatus for a fruit or vegetable product includes a maturity determination device to determine a maturity level of the fruit or vegetable product; a harvester to harvest the fruit or vegetable product; a power source generator to drive the harvester; and a controller to determine whether or not to supply the power to the harvester based on a determination result on the maturity level provided by the maturity determination device.
Claims16
A method for harvesting a fruit or vegetable product using a harvesting apparatus including a maturity determination device that determines a maturity level of the fruit or vegetable product and a harvester that harvests the fruit or vegetable product, the method comprising the steps of:
- determining the maturity level of the fruit or vegetable product by the maturity determination device to acquire a determination result on the maturity level, and determining whether the fruit or vegetable product is harvestable or not based on the determination result on the maturity level to acquire a determination result on whether the fruit or vegetable product is harvestable or not;
- determining an operation of the harvester based on the determination result on the maturity level;
- harvesting the fruit or vegetable product based on the determination on the operation of the harvester;
- and
- notifying, by using a notification device, a user of the harvesting apparatus of whether the fruit or vegetable product is harvestable or not based on the determination result on whether the fruit or vegetable product is harvestable or not.
A harvesting apparatus for a fruit or vegetable product, comprising:
- a maturity determination device that determines a maturity level of the fruit or vegetable product;
- a harvester that harvests the fruit or vegetable product;
- a power source generator that generates power to drive the harvester;
- and
- a controller that determines whether or not to supply the power to the harvester based on a determination result on the maturity level provided by the maturity determination device;
- and
- a notification device;
- wherein
- the maturity determination device determines whether the fruit or vegetable product is harvestable or not based on the determination result on the maturity level;
- and
- the notification device notifies a user of the harvesting apparatus of whether the fruit or vegetable product is harvestable or not based on a determination result on whether the fruit or vegetable product is harvestable or not.
A method for harvesting a fruit or vegetable product using a harvesting apparatus including a maturity determination device that determines a maturity level of the fruit or vegetable product and a harvester that harvests the fruit or vegetable product, the method comprising the steps of:
- determining the maturity level of the fruit or vegetable product by the maturity determination device to acquire a determination result on the maturity level;
- determining an operation of the harvester based on the determination result on the maturity level;
- and
- harvesting the fruit or vegetable product based on the determination on the operation of the harvester;
- wherein
- the step of acquiring the determination result on the maturity level includes the steps of:
- receiving an image including at least a part of the fruit or vegetable product, the image including at least an intensity distribution of light of a first wavelength band, an intensity of the light of the first wavelength band reflected by the fruit or vegetable product varying in accordance with the maturity level;
- finding an area size ratio of the intensity distribution of the light of the first wavelength band on the basis of a predetermined reference value;
- and
- determining the maturity level in accordance with the area size ratio to acquire the determination result on the maturity level.
