Fruit size compensation method and apparatus for light characteristic on-line detection of fruit internal quality

Abstract

The invention relates to a fruit size compensation method and apparatus of a fruit inner quality light peculiarity online detecting. The apparatus is formed by a transmitting unit, a size detecting unit, a size compensation unit, a control unit and a driving unit. The fruit moves in the transmitting unit by rotating stage; the size detecting unit obtains the size information of the fruit; the encoder obtains the location information of the fruit; the size information and the location information are transmitted into the control unit after analyzing and processing; the control information is transmitted into the driving unit; the driving size compensation unit dose size compensation.

Description

technical field [0001] The invention relates to a fruit size compensation method and device for online detection of optical characteristics of internal quality of fruit, in particular to a method and device for online detection of spherical fruits or spherical agricultural products. Background technique [0002] On-line non-destructive testing based on the optical characteristics of the internal quality of fruits has attracted more and more people's attention, because it is non-destructive and fast in detection speed, and can well meet the requirements of factory fruit post-harvest processing and grading, and has become an online internal quality inspection and grading of fruit. one of the important methods. At present, the online non-destructive testing device for the internal quality of fruits is immature and there are many problems: such as the detection accuracy and detection speed need to be improved. Many of these problems are solved by improving the stability and ada...

Problems solved by technology

At present, the online non-destructive testing device for the internal quality of fruits is immature and there are many problems: such as the detection accuracy and detection speed need to be improved

There are certain problems in the current detection method: the height of the light irradiated by this type of device and the detection probe are fixed. If the size of the fruit to be tested is not uniform, the detection position for each fruit will be different. The detection position is not consistent with the detection position of the fruit during modeling, which causes a large detection error

Since the transmitted light signal is very weak, if the detection probe is fixed, the distance between the detection probe and the surface of the fruit is affected by the size of the fruit during the detection, and the intensity of the detected light signal also changes accordingly, which affects the detection accuracy. For the change of detection accuracy caused by the change of fruit detection position due to the change of fruit size, it still exists in the transmission method.

[0008] To sum up, when using the optical characteristics of fruit for online detection of fruit internal quality, the change of fruit size will cause the change of fruit detection position, which will cause the change of detection accuracy; and for the transmission method, the detection accuracy should also be considered after the change of fruit size. The loss of optical signal transmission caused by the change of the distance between the probe and the fruit surface and the change of detection accuracy
