1. A system for scanning a plurality of items present inside an object to generate a distortion corrected and color mapped image of the plurality of items, the system comprising:
a first electromagnetic radiation sensor detects electromagnetic radiation obstructed by the plurality of items inside the object that is travelling through a continuous conveyor belt and generates a first signal for profiling the plurality of items present inside the object;
a second electromagnetic radiation sensor that is positioned inside a tunnel at entry point, wherein the second electromagnetic radiation sensor senses a presence of the object inside the tunnel, wherein the second electromagnetic radiation sensor detects the electromagnetic radiation obstructed by the object and generates a second signal;
an electromagnetic radiation generator that is positioned below the tunnel that receives the second signal from the second electromagnetic radiation sensor to generate an angular beam of electromagnetic radiation on the object, wherein the electromagnetic radiation generator is inclined at an angle in the range of 10 to 50 degree with reference to the ground level on Y axis;
a third electromagnetic radiation sensor that is positioned inside the tunnel at an exit point, wherein the third electromagnetic radiation sensor senses the object when leaving the tunnel after crossing the electromagnetic radiation generator, wherein the third electromagnetic radiation sensor detects the electromagnetic radiation obstructed by the object and generates a third signal to trigger the electromagnetic radiation generator to terminate the generation of the angular beam of electromagnetic radiation on the object;
a fourth electromagnetic radiation sensor that is positioned above the tunnel that detects the angular beam of electromagnetic radiation that are passed through the object in three dimensions and generates a fourth signal, wherein the fourth electromagnetic radiation sensor is inclined at an angle in the range of 10 to 50 degree with reference to the Z axis;
a processor; and
a memory unit operably coupled to the processor, wherein the memory unit stores a plurality of instruction codes which when executed by the processor, wherein the processor is configured to,
generate profile data of the plurality of items present inside the object by processing the first signal received from the first electromagnetic radiation sensor;
determine a shape of the plurality of items present inside the object by profiling the plurality of items with the profile data;
categorize the plurality of items present inside the object being scanned by color mapping by computing an atomic mass number of the plurality of items that is determined from the fourth signal received from the fourth electromagnetic radiation sensor, wherein the category of plurality of items comprises metallic, organic, inorganic;
generate a distortion corrected and color mapped image of the plurality of items present inside the object by (a) generating composite radiation data of the plurality of items present inside the object from the fourth signal received from the fourth electromagnetic radiation sensor, (b) modifying the composite radiation data of the plurality of items present inside the object by comparing the profile data of the plurality of items present inside the object with the composite radiation data, and (c) processing the computed atomic mass number of the plurality of items present inside the object respectively; and
display the distortion corrected and the color mapped image of the plurality of items present inside the object through a user interface.
