Abstract

A wearable data acquisition system is described in which the data input devices are contained within a headpiece apparatus thereby permitting the operator to control acquisition integration of image capture and display in a hands free environment. The system includes a portable data terminal communicating with the headpiece apparatus which comprises an image acquisition device having a target pattern generator for providing visual feedback for aiming and range-finding, a microphone for receiving voice commands from a human operator to the portable data terminal, and a speaker whereby the human operator receives audio feedback from the portable data terminal. In another embodiment of the present invention, the headpiece apparatus further comprises an image display system having a scanning laser heads-up display for projecting image data into the vision field of the human operator. This image display system allows the human operator to preview an image to be captured or to recall stored image data from the memory of the portable data terminal.

Claims

1. A wearable data acquisition system comprising:

a data terminal; and

a headpiece apparatus adapted to be worn by an operator, wherein the headpiece apparatus comprises;

an image acquisition device adapted to communicate with the data terminal;

a microphone for receiving voice commands from the operator for transmission to the data terminal; and

a speaker for receiving signals from the data terminal and transmitting audio signals to the operator.

2. The wearable data acquisition system as claimed in claim 1 wherein the data terminal is a portable terminal adapted to be located on the operator.

3. The wearable data acquisition system as claimed in claim 2 wherein the data terminal is connected to the headpiece apparatus by cables.

4. The wearable data acquisition system as claimed in claim 1 wherein the data terminal is a terminal adapted to be located remote from the operator.

5. The wearable data acquisition system as claimed in claim 1 wherein the headpiece apparatus and the data terminal include wireless communications means.

6. The wearable data acquisition system as claimed in claim 1 wherein the data terminal comprises:

a data bus, a microprocessor, a memory, a keyboard and a display and/or a touch screen interface.

7. The wearable data acquisition system as claimed in claim 1 wherein the headpiece apparatus further comprises an image display system adapted to be viewed by the operator.

8. The wearable data acquisition system as claimed in claim 7 wherein the image display system comprises a scanning laser heads-up display for projecting image data into the vision field of the operator.

9. The wearable data acquisition system as claimed in claim 1 comprising a remote display unit adapted to be worn on the operator.

10. The wearable data acquisition system as claimed in claim 1 comprising a thumb-activated switch adapted to be worn on a finger of the operator to manually activate an acquisition sequence.

11. The wearable data acquisition system as claimed in claim 1 wherein the headpiece apparatus includes a pair of eyeglasses.

12. The wearable data acquisition system as claimed in claim 1 wherein the headpiece apparatus includes a hat.

13. The wearable data acquisition system as claimed in claim 1 wherein the headpiece apparatus includes a helmet.

14. The wearable data acquisition system as claimed in claim 1 wherein the headpiece apparatus includes a set of earphones.

15. The wearable data acquisition system as claimed in claim 1 wherein said image acquisition device is a solid-state imager.

16. The wearable data acquisition system as claimed in claim 1 wherein the image acquisition device includes a target pattern generator.

17. The wearable data acquisition system as claimed in claim 16 wherein the target pattern generator is a laser-based target pattern generator.

18. The wearable data acquisition system as claimed in claim 16 wherein the target pattern generator is an LED-based target pattern generator.

19. The wearable data acquisition system as claimed in claim 1 wherein the image acquisition device includes a target range finder.

20. The wearable data acquisition system as claimed in claim 19 wherein the target range finder is an ultrasonic transducer.

21. The wearable data acquisition system as claimed in claim 1 wherein the microphone is a mini-boom microphone.

22. The wearable data acquisition system as claimed in claim 1 wherein the speaker is an ear bud style speaker.

23. A method of operating a wearable data acquisition system having an image acquisition device on a headpiece apparatus adapted to be worn by an operator comprising the steps of:

a. positioning the headpiece apparatus before a target such that the image acquisition device views the target;

b. adjusting the relative position between the headpiece apparatus and the target until the image acquisition device is in the optimal range of the target; and

c. triggering an image acquisition cycle by the data acquisition system when the image acquisition device is in the optimal range of the target.

24. A method of operating a wearable data acquisition system as claimed in claim 23 wherein step b. includes:

b.1. projecting a target pattern on the target for aiming the image acquisition device and for determining when the image acquisition device is in the optimal range of the target.

25. A method of operating a wearable data acquisition system as claimed in claim 23 wherein step b. includes:

b.1. projecting a target pattern on the target for aiming the image acquisition device; and

b.2. projecting a range-finding signal on the target for determining when the image acquisition device is in the optimal range of the target.

26. A method of operating a wearable data acquisition system as claimed in claim 23 wherein the step c. comprises:

c.1. triggering the image acquisition cycle is by voice command by the operator.

27. A method of operating a wearable data acquisition system as claimed in claim 23 wherein the step c. comprises:

c.1. manually triggering the image acquisition cycle is by the operator.
