Research scientists in Wroclaw Poland have asked to use the DVIS to pinpoint the location of pests in crops. The DVIS acts as a GPS system for local space. Histogram filters might be used to highlight and identify precise locations of insects in food.
Leaves hide lemons.

Lemons become clearly visible.
Imaging3 has been approached by a company in Australia which slaughters 3,000 head of cattle per day. The outfit were interested to use the DVIS to instantly quantify the amount of meat, fat, bone in a cow on an assembly line. The V in DVIS stands for volumetric for materials which do not completely attenuate xrays.
In Continuous 3D Scan mode corn is exposed to equivalent of several days of sunlight radiation roughly every few seconds. In this time the vegetable can be disassembled from the bottom by robotics end effectors guided by the DVIS.
Head of corn is lowered into the DVIS.
Filters focus only on the husk and leaves.
Filters focus only on the husk and fur.
Filters focus only on the kernels.
Filters focus on the cob. SafeSlice is used so that human audience can see the cob. The machine vision system that guides the end effectors does not need SafeSlice. It does its job while seeing an object from the inside and the outside simultaneously.
The cob can be rotated manipulated and viewed from different angles concurrently. All the while the position and form of the corn (husk, kernels, cob intact) lowered into the DVIS remains unaltered.
In Continuous 3D Scan mode an apple is examined for surface and internal punctures. Internal hole size can be precisely measured by applying a slice tangential to the surface at the location of the penetration. This application needs to run fast enough to process 12 fruit per second.
Home Depot drills are used to make holes in apple.
Apple is mounted with the help of a tie wrap.
Big holes are highligthed on the surface.
Three smallest holes on the surface and tie wrap are highligthed.
Good close-up view of 5/64 inch diameter penetration on the surface. It looks not unlike a crater on the surface of a planet in a JPL/NASA image.
Three smallest holes can be seen on the surface.
Three smallest holes can be seen on the surface and inside.
Three smallest holes path can be followed deep inside the apple as the slice shifts.
In 2016, while waiting for the business people and lawyers to finish their work, the technology department was discussing the feasibility of using the DVIS to spot food contamination with a professor from UC Davis.
On his instructions we inserted metal, wood, plastic, and glass particles into a package of hot dogs. Below are the results of the research to see how these would look in a 3D model created by the DVIS.
The hot dog had to be sliced digitally in order to allow humans to see the inside view.
The requirement is to analyze food at a rate of 10-12 fruits or packages per second.
While this pace is beyond the capabilities of the current model it is not a far-fetched demand.
The next time you bite into a hot dog and find an accidental left over fragment from the food harvesting and preparation process in your mouth you will wish the DVIS was on the market to pinpoint and isolate foreign material in food.

Imaging3 has used chickens in boxes from the local KFC outlet and oranges as well as avocados with pits from the local Ralphs market as subjects of demo images. Ideas were kicked around the Burbank skunk works to use the DVIS to guide robotics end effectors to cut and manipulate food articles during preparation.
