The present disclosure relates to methods and systems for obtaining image information of an organism including a set of optical data; calculating a growth index based on the set of optical data; and calculating an anticipated harvest time based on the growth index, where the image information includes at least one of: (a) visible image data obtained from an image sensor and non-visible image data obtained from the image sensor, and (b) a set of image data from at least two image capture devices, where the at least two image capture devices capture the set of image data from at least two positions.
1. A method comprising:
obtaining image information of an organism comprising a set of image data;
calculating a growth index based on the set of image data; and
calculating an anticipated harvest time based on the growth index,
wherein the image information is obtained by at least two image capture devices, wherein the at least two image capture devices capture the set of image data from at least two different positions, wherein the image information comprises RGB image data obtained using a sensor detecting RGB light, and NIR (near infrared) image data obtained using a sensor detecting NIR light, wherein the image capture devices are installed at an angle to capture, in the obtained image information, R light intensity and NIR light intensity of incident light that is not reflected from the organism and light intensity of light that is reflected from the organism, and wherein the growth index is calculated based on measured R light intensity and NIR light intensity of the incident light that is not reflected from the organism and the light intensity of light that is reflected from the organism.
2. The method of claim 1 , wherein the image information comprises visible image data and non-visible image data and wherein the visible image data is generated by demosaicing of a RGB pixel signal to provide R, G and B component image signals and wherein the non-visible image data is generated based on a demosaiced R and IR signal.
3. The method of claim 1 , wherein the image information comprises visible image data and non-visible image data and wherein the visible image data is generated by demosaicing of a RGB pixel signal to provide R, G and B component image signals and wherein the non-visible image data is generated based on a R and IR signal without demosaicing.
4. The method of claim 1 , wherein the image capture devices used to obtain the set of image data each comprise a stack type image sensor, wherein the stack type image sensor has a blue light sensor layer stacked on a green light sensor layer, wherein the green light sensor layer is stacked on a red light sensor layer, and wherein the red light sensor layer is stacked on a near-infrared ray (NIR) sensor layer.
5. The method of claim 1 , wherein the image capture devices used to obtain the set of image data each comprise a set of RGB color filters provided over a laminated film, wherein the laminated film comprises at least one of SiO and SiN, and wherein the set of RGB color filters comprises a FR color filter, a FG color filter, and a FB color filter.
6. The method of claim 1 , further comprising calculating parallax image data based on at least two of the image data from the set of image data obtained from the at least two image capture devices; and calculating the growth index based on the parallax image data.
7. The method of claim 1 , wherein the image capture devices each comprise a set of RGB color filters provided over a set of infrared (IR) cut filters, wherein the set of IR cut filters is provided over a set of RGB sensors, wherein the image sensor further comprises a black filter provided over a NIR (near infrared) sensor with no IR cut filter provided over the NIR sensor and therefore with no blocking of NIR from the NIR sensor.
8. A method comprising:
obtaining image information of an organism comprising a set of image data;
calculating a growth index based on the set of image data; and
calculating an anticipated harvest time based on the growth index,
wherein the image information comprises RGB image data obtained using a sensor detecting RGB light, and NIR (near infrared) image data obtained using a sensor detecting NIR light, wherein the sensors are installed to capture, in the obtained image information, R light intensity and NIR light intensity of incident light that is not reflected from the organism and light intensity of light that is reflected from the organism, and wherein the growth index is calculated based on measured R light intensity and NIR light intensity of the incident light that is not reflected from the organism and the light intensity of light that is reflected from the organism.
