OPTICAL PROJECTION OVERLAY DEVICE

摘要

Devices and methods for producing a highlighted overlay of a region, including an illumination source configured to illuminate the region at a bandwidth containing a first wavelength at a working distance, an imager at a working distance configured to image the illuminated region at a bandwidth containing a second wavelength, where the first and second bandwidths and wavelengths are not visible, a visible light projector configured to illuminate the region and registered to the imager to produce alignment of imaged feature with projected features at the same location on the region, and a controller executing a program configured to filter acquired images from the imager to identify areas of the region of a predetermined light intensity, and control the projector to visibly highlight those areas on the region.

1. A device for producing an overlay of a region, comprising;
an illumination source configured to illuminate the region at a bandwidth containing a first wavelength at a working distance; an imager at a working distance configured to image the illuminated region at a bandwidth containing a second wavelength, where the first and second bandwidths and wavelengths are not visible; a visible light projector configured to illuminate the region and registered to the imager to produce alignment of imaged feature with projected features at the same location on the region, and; at least one of a controller executing a program or logic configured to filter acquired images from the imager to identify areas of the region of a predetermined light intensity, and control the projector to project a visible image of those areas those areas on the region.
