1. An apparatus for imaging within a wellbore comprising: a base;a plurality of actuatable members disposed axially adjacent to the base;a drive mechanism to extend and contract the actuatable members; andan actuatable member displacement sensor,wherein repeated imaging occurs within the wellbore without retrieval of the apparatus from the wellbore. 2. The apparatus of claim 1 wherein the base comprises solid or hollow polyhedron, cylinder, sphere, cone, torus, or combinations thereof. 3. The apparatus of claim 1 wherein the base can be made from a material comprising metal, iron, copper, aluminum, lead, alloys, steel, base, brass, bronze, organic polymers, synthetic polymers, or combinations thereof. 4. The apparatus of claim 1 wherein the actuatable members comprise pins, needles, sticks, welding sticks, rods, wands, spears, spikes, nails, or combinations thereof. 5. The apparatus of claim 4 wherein the actuatable members are extendable, contractable, collapsible, or a combination thereof. 6. The apparatus of claim 4 wherein the actuatable members comprises a pin having a diameter of less than about 2 cm and a length of more than about 1 cm members. 7. The apparatus of claim 5 wherein the actuatable member comprises an extendible and collapsible pin having a diameter of less than about 5 mm. 8. The apparatus of claim 5 wherein the actuatable members comprises an extendible and collapsible pin having a diameter of less than about 2 mm. 9. The apparatus of claim 1 wherein the number of actuatable members is at least five. 10. The apparatus of claim 1 wherein the number of actuatable members per two cm2 is at least one. 11. The apparatus of claim 1 wherein the actuatable members can be made from a material comprising metal, iron, copper, aluminum, lead, alloys, steel, base, brass, bronze, organic polymers, synthetic polymers, or combinations thereof. 12. The apparatus of claim 1 wherein the drive mechanism comprises a pressure chamber, a hydraulic pressure chamber, a spring loaded pressure chamber, a magnetic drive mechanism; an electric drive mechanism, springs, or combinations thereof. 13. The apparatus of claim 1 wherein the actuatable members may be axially displaced upon contact with an object within the wellbore. 14. The apparatus of claim 13 wherein the axially displaced actuatable members form a representation of the object. 15. The apparatus of claim 1 further comprising a protective casing, wherein the protective casing shields the actuatable members from the wellbore environment. 16. The apparatus of claim 1 further comprising a memory device disposed adjacent to the base. 17. The apparatus of claim 16 wherein the memory device stores information concerning the wellbore. 18. A method of servicing a wellbore comprising: providing an apparatus comprising a base and a plurality of actuatable members disposed axially adjacent to the base, and an actuatable member displacement sensor;lowering the apparatus into the wellbore to a position near an object within the wellbore;contacting the actuatable members with the object wherein the contacting comprises axially displacing the actuatable members;forming a representation of the object;interpreting the representation of the object; andusing the representation of the object to select a fishing tool to retrieve the object from the wellbore,repeating the steps without retrieval of the apparatus from the wellbore. 19. The method of claim 18 further comprising saving the representation of the object to a memory device. 20. The method of claim 19 comprising forming multiple representations of the object and comparing the saved representations of the object to identify the object.
