Apparatus and method for measuring growth volume of plant

Apparatus and method for measuring plant growth according to the present invention easily measure the circumferential length and intercution length of the plant using a plurality of optical devices， and accurately measure the growth amount of the plant according to the measured circumferential length and intercutaneous length value of the plant In one embodiment， the apparatus includes: a measuring unit measuring a circumferential length and an intercution length of a plant using a reflection pattern signal of reflected light with respect to light generated by generating light; And comparing the circumferential length and intercution length of the plant measured by the measuring unit with the circumferential length and intercution length of the previously measured plant， respectively， and calculating the amount of change in the circumferential length and the intercutaneous length of the plant， respectively， And a control unit for calculating the growth amount of the plant using the change amount of the intercalar length.

本发明所提出的植物生长测量装置及方法，可借助多个光学设备便捷地获取植物的茎周长与节间长度，并基于实测得到的植物茎周长及节间长度值，精准测算植物的生长量。在一个实施例中，该装置包括：测量单元，其通过对生成光线所产生的反射光的反射图案信号，来测量植物的茎周长与节间长度；控制单元，其将测量单元测得的植物茎周长、节间长度分别与此前测得的对应植物茎周长、节间长度进行比对，分别计算出植物的茎周长变化量与节间长度变化量，并利用节间长度的变化量计算得到植物的生长量。
