For example, a portable device can include a chamber that forms a reference environment for a camera device to capture an image of a sample material in an interior of the chamber. The portable device can include an opening to the interior of the chamber and a stage configured to position the sample material on a surface area and at a distance from the camera device. As such, the camera device can capture the image of the sample material at a resolution that enables ascertaining an attribute of the sample material based on a detectable physical characteristic of the sample material. The detectable physical characteristic of the sample material includes a color, size, shape, or texture. ## Claims ### Claim 1 A system comprising: a portable scanning device including: a chamber configured as a controlled environment for capturing an image of a sample material contained in the chamber; an openable member configured to enable access to the chamber, wherein ambient light of an external environment is blocked from the chamber when the openable member is closed; an exterior surface configured to receive a handheld mobile device that includes a camera device; an interior surface of the chamber configured to stage the sample material; and an opening through the exterior surface to the chamber to enable the camera device of the handheld mobile device to capture the image of the sample material when the handheld mobile device is positioned on the exterior surface such that the camera device is positioned over the opening and faces the interior surface. ### Claim 2 (depends on 1) The system of claim 1 further comprising: a server configured to: process data of the image, wherein the data of the image is received over a network from the handheld mobile device; and determine an attribute of the sample material based on the processed data of the image. ### Claim 3 (depends on 1) The system of claim 1, wherein the interior surface is a floor of the chamber. ### Claim 4 (depends on 1) The system of claim 1 further comprising: a light source configured to radiate light on the sample material when disposed on the interior surface. ### Claim 5 (depends on 4) The system of claim 4, wherein the radiated light includes at least one of white or colored LED or incandescent light, ultraviolet (UV) light, or infrared (IR) light. ### Claim 6 (depends on 4) The system of claim 4, wherein the light source is a removable device. ### Claim 7 (depends on 1) The system of claim 1, wherein the interior surface comprises: a marker that enables the mobile device to autofocus the camera device. ### Claim 8 (depends on 1) The system of claim 1, wherein the exterior surface comprises: a plurality of positioners configured to orient the handheld mobile device for capturing the image of the sample material with the camera device. ### Claim 9 (depends on 8) The system of claim 8, wherein a positioner is adjustable to fit a plurality of handheld mobile devices of different sizes. ### Claim 10 A method comprising: capturing an image of a sample material contained in an enclosed chamber of a portable scanning device, wherein the image is captured by a camera device of a mobile device disposed on an exterior surface of the portable scanning device, and wherein the sample material is staged on a floor of the enclosed chamber; and ascertaining an attribute of the sample material based on the image. ### Claim 11 (depends on 10) The method of claim 10, wherein the sample material is a biological material. ### Claim 12 (depends on 10) The method of claim 10, wherein the sample material is a plant-based material, and the attribute of the plant-based material is determined in accordance with machine learning techniques. ### Claim 13 (depends on 10) The method of claim 10, wherein ascertaining the attribute of the sample material comprises: comparing the image to data of another image of the sample material to verify the attribute. ### Claim 14 (depends on 10) The method of claim 10, wherein ascertaining the attribute of the sample material comprises: comparing the image to data of a plurality of images of authenticated samples. ### Claim 15 A portable scanning device comprising: a chamber configured as a controlled environment for capturing an image of a sample material contained in the chamber; an openable member configured to enable access to the chamber for receiving the sample material, wherein ambient light of an environment external to the chamber is blocked from the chamber when the openable member is closed; a surface inside the chamber configured to stage the sample material for capturing the image of the sample material; and an imaging device configured to capture the image of the sample material when disposed on the surface inside the chamber. ### Claim 16 (depends on 15) The portable scanning device of claim 15 further comprising: a touchscreen integrated in an exterior surface of the scanning device, wherein the touchscreen enables a user to control of the imaging device. ### Claim 17 (depends on 15) The portable scanning device of claim 15, wherein the imaging device is a camera integrated in a surface of the chamber and facing the surface. ### Claim 18 (depends on 15) The portable scanning device of claim 15, wherein the surface inside the chamber is a floor of the chamber.
