Abstract

A method and apparatus for printing an image on a large surface area or walkway provides for imagewise marking of the surface with a color marking solution, to form a visible image on the surface during an image recording mode of a marking engine. The marking engine includes a scanner and the marking engine moves along the surface and operates the scanner to sense a crude image upon the surface and generates data signals representing the crude image or boundaries defined by the crude image scanned. In response to data signals the marking engine is operated to print an enhanced image of the crude image and/or to color the crude image so that the printing overlies the crude image.

Claims

1. An apparatus for printing an image on a surface, the apparatus comprising:

a movable marking engine including a scanner, the marking engine moving along the surface and the scanner being operative to sense a crude image upon the surface and to generate data signals representing the crude image or boundaries defined by the crude image scanned; and

a controller for controlling the marking engine, the controller being responsive to the data signals to control the marking engine to print an enhanced image of the crude image and/or to color the crude image so that the printing overlies the crude image, wherein the marking engine is supported on a self-propelled vehicle that includes a drive that engages the surface at plural locations for moving the marking engine along the surface.

2. The apparatus of claim 1 and including a display that displays the crude image sensed by the scanner.

3. The apparatus of claim 1 and wherein the crude image represents an outline and the controller controls the marking engine to colorize the crude image within the scanned boundaries.

4. The apparatus of claim 1 and wherein the controller controls the marking engine to advance the scanner to scan the crude image in straight raster lines.

5. The apparatus of claim 4 and wherein the controller controls the marking engine to first scan a first predetermined entire area during a first pass and then controls the marking engine to print and/or color upon the area in a second pass.

6. The apparatus of claim 5 and wherein the marking engine is located outboard of an area defined by lines connecting the plural locations so that during operation of the marking engine for imagewise printing and/or coloring the drive does not engage areas of the surface that have been previously imagewise printed and/or colored by the marking engine.

7. The apparatus of claim 5 and wherein the marking engine is an ink jet marking device.

8. The apparatus of claim 5 and wherein a signaling device is provided external to the boundary to emit a signal to identify a boundary location of a predetermined area that includes the crude image.

9. The apparatus of claim 8 and wherein the signaling device comprises a laser beam emitter that emits a laser beam signal and a reflector is mounted on the vehicle and reflects the laser beam signal to a sensor.

10. The apparatus of claim 1 and wherein the marking engine is an ink jet marking device.

11. The apparatus of claim 1 and wherein the controller controls the marking engine to advance the scanner to scan the crude image in a path defined by the crude image.

12. The apparatus of claim 1 and wherein the controller controls the marking engine to first scan a first predetermined entire area during a first pass and then controls the marking engine to print upon and/or color the area in a second pass.

13. The apparatus of claim 12 and wherein the marking engine is an ink jet marking device.

14. The apparatus of claim 1 and wherein the marking engine is located outboard of an area defined by lines connecting the plural locations so that during operation of the marking engine for imagewise printing and/or coloring the drive does not engage areas of the surface that have been previously imagewise printed and/or colored by the marking engine.

15. A method for printing an image on a surface, the method comprising the steps of:

providing a movable marking engine that includes a scanner, the marking engine mounted on a self-propelled vehicle that includes a drive that engages the surface at plural locations for moving the marking engine along the surface;

moving the marking engine via the self-propelled vechicle along the surface and operating the scanner to sense a crude image upon the surface and generating data signals representing the crude image or boundaries defined by the crude image scanned; and

in response to the data signals operating the marking engine to print an enhanced image of the crude image and/or to color the crude image so that the printing overlies the crude image.

16. The method of claim 15 and including generating a display of the crude image sensed by the scanner.

17. The method of claim 15 and wherein the crude image represents an outline and the marking engine colorizes the crude image within the scanned boundaries.

18. The method of claim 15 and wherein the marking engine advances the scanner to scan the crude image in straight raster lines.

19. The method of claim 18 and wherein the marking engine first scans a first predetermined entire area during a first pass and then controls the marking engine to print and/or color upon the area in a second pass.

20. The method of claim 15 and wherein the marking engine is located outboard of an area defined by lines connecting the plural locations so that during operation of the marking engine for imagewise printing and/or coloring a drive does not engage areas of the surface that have been previously imagewise printed and/or colored by the marking engine.

21. The method of claim 20 and wherein the marking engine is an ink jet marking device.

22. The method of claim 15 and wherein the marking engine is an ink jet marking device.

23. The method of claim 15 and wherein the marking engine advances the scanner to scan the crude image in a path defined by the crude image.

24. The method of claim 15 and wherein the marking engine first scans a first predetermined entire area during a first pass and then the marking engine prints upon and/or colorizes the area in a second pass.

25. The method of claim 24 and wherein the marking engine is an ink jet marking device.

26. The method of claim 15 and wherein the marking engine is an ink jet marking device.

27. The method of claim 15 and wherein a signaling device is provided external to the boundary and emits a signal to identify a boundary location of a predetermined area that includes the crude image.

28. The method of claim 27 and wherein the signal comprises a laser beam signal and the signal is reflected from the vehicle supporting the marking engine.

29. The method of claim 15 and wherein the marking engine is located outboard of an area defined by lines connecting the plural locations so that during operation of the marking engine for imagewise printing and/or coloring a drive does not engage areas of the surface that have been previously imagewise printed and/or colored by the marking engine.

30. The method of claim 15 and wherein a selection is provided of plural stored images for printing and in response to a selection of a particular stored image and the sensing of the crude image the marking engine prints the enhanced image.

31. The method of claim 15 and wherein image data representing a character or logo is prestored in a memory associated with the marking engine before scanning of the crude image and in response to a selection for printing of such character or logo and the scanning of the crude image the enhanced image is printed by the marking engine.

32. The method of claim 15 and wherein the crude image sensed is printed as an enhanced image and in a repeating pattern of the enhanced image.

33. The method of claim 15 and wherein a handheld marker is used to create the crude image upon the surface which is a walkway.

34. The method of claim 15 and wherein the surface is a walkway.

35. An apparatus for printing an image on a surface, the apparatus comprising:

a movable marking engine including a scanner, the marking engine moving along the surface and the scanner being operative to sense a crude image upon the surface and to generate data signals representing the crude image or boundaries defined by the crude image scanned;
