Abstract

A camera mount for taking panoramic pictures. A camera mounting plate is rotatably attached to a tripod mounting plate in a manner permitting the camera mounting plate to sweep an arc of rotation along the top surface of the tripod mounting plate. The tripod mounting plate has a convexly-curved forward edge and a protractor disposed adjacent the forward edge. A stationary detent is fixedly attached adjacent to the center of the protractor and a plurality of adjustable detents are disposed to each side of the stationary detent within respective detent slots disposed along the arc of rotation adjacent to the protractor. The camera mounting plate includes a camera mounting block that can be adjusted rearwardly and forwardly upon the camera mounting plate. A pointer integrally formed as part of the camera mounting plate includes a transparent eyeglass disposed above the protractor having a datum to facilitate alignment of the pointer with the protractor. A bubble level is also provided to facilitate leveling of the camera mounted on the device of the present invention. A rotary incremental optical encoder is attached to the camera mounting plate for converting angular displacement of the camera mounting plate into digital readout.

Claims

1. A camera mount for taking panoramic pictures comprising:

a tripod mounting plate having a top surface, a bottom surface and angular position setting means disposed in said tripod mounting plate;

a camera mounting plate having a top surface and a bottom surface, said camera mounting plate being rotatably attached to the top surface of said tripod mounting by rotatably mounting means to circumscribe an arc of rotation, said camera mounting plate having a roller bearing fixedly attached to the bottom surface of said camera mounting plate which selectively engages the angular position setting means of said tripod mounting plate, camera attachment means being disposed on the top surface of said camera mounting plate;

first order angular position measuring means disposed on said tripod mounting plate for measuring to a first degree of accuracy rotation of said camera mounting plate; and

second order angular position measuring means communicating with said camera mounting plate for measuring to a second degree of accuracy rotation of said camera mounting plate, said second degree of accuracy being a more accurate measurement than said first degree of accuracy.

2. A camera mount as described in claim 1 wherein the arc of rotation circumscribed by said camera mounting plate equals 100 degrees.

3. A camera mount as described in claim 1 wherein said angular position setting means comprises a plurality of detents disposed on the top surface of said tripod mounting plate.

4. A camera mount as described in claim 3 wherein said plurality of detents are slidably adjustable along a line parallel to the arc of rotation circumscribed by said camera mounting plate.

5. A camera mount as described in claim 3 wherein the plurality of detents comprises a centrally-disposed stationary detent and a plurality of adjustable detents disposed to each side of said stationary detent, said adjustable detents being slidably adjustable along a line parallel to the arc of rotation of said camera mounting plate.

6. A camera mount as described in claim 1 wherein said second order angular position measuring means comprises a rotary encoder attached to said camera mounting plate to rotate therewith.

7. A camera mount as described in claim 6 wherein said rotary encoder is an optical encoder.

8. A camera mount as described in claim 7 wherein said optical encoder is an incremental encoder.

9. A camera mount as described in claim 8 further including digital numerical data display means communicating with said rotary incremental optical encoder and attached to said tripod mounting plate.

10. A camera mount as described in claim 1 wherein said first order angular position measuring means comprises a protractor having protractor graduations disposed thereon along the arc of rotation of said camera mounting plate at a forward edge of said tripod mounting plate.

11. A camera mount for taking panoramic pictures comprising:

a tripod mounting plate having a top surface and a bottom surface and including angular position setting means comprising a plurality of detents slidably adjustable in said tripod mounting plate along a line parallel to an arc of rotation circumscribed by a camera mounting plate;

said camera mounting plate having a top surface and a bottom surface, said camera mounting plate being rotatably attached to the top surface of said tripod mounting plate by rotatably mounting means to circumscribe an arc of rotation, said camera mounting plate having a roller bearing fixedly attached to the bottom surface of said camera mounting plate which selectively engages the angular position setting means of said tripod mounting plate, camera attachment means being disposed on the top surface of said camera mounting plate;

first order angular position measuring means comprising a protractor having protractor graduations disposed thereon along the arc of rotation of said camera mounting plate; and

second order angular position measuring means comprising a rotary encoder operably attached to the camera mounting plate.

12. A camera mount as described in claim 11 wherein the angular position setting means comprises a centrally-disposed stationary detent and a plurality of adjustable detents disposed to each side of said stationary detent, said adjustable detents being slidably adjustable along a line parallel to the arc of rotation of said camera mounting plate.

13. A camera mount as described in claim 11 wherein said rotary encoder is an optical encoder.

14. A camera mount as described in claim 13 wherein said optical encoder is an incremental encoder.

15. A camera mount as described in claim 11 further including digital numerical data display means communicating with said rotary encoder and attached to said tripod mounting plate.
