Abstract
The invention provides a projector projection imaging and video image synchronization display and measurement method and device. A measured workpiece is arbitrarily placed on an instrument work table. Contour enlarging imaging is carried out on the measured workpiece through an objective. An objective group with a prism and a magnification reducing objective are designed. A part of a light directly passes through the objective group and is imaged on a projection screen with star-shaped lines. The other part of the light is steered through the objective group and is imaged on a CCD photosensitive surface through the magnification reducing objective. An image on the CCD photosensitive surface is displayed and processed in real time on a computer screen through hardware and software. When the projection screen is used to observe the image, the computer screen can simultaneously display the observed image. Through the method, all functions of the original projector are retained, and CCD video image synchronous display and processing are realized at the same time. According to the invention, an optical path is divided into two parts; the workpiece contour image is imaged in two different image spaces; the synchronization of optical projection zoom comparison measurement and CCD video image measurement is realized; and the device has the measurement function of a traditional projector and a CCD video measurement function.

Currently, development along with video measuring instrument, it is convenient, fast, intuitively metering system increasingly obtain the accreditation of user, the trend of big substituted conventional projector, therefore measure Function Integration Mechanism making conventional projector realize quickly measuring as video instrument to conventional projector by video instrument is a problem demanding prompt solution.
Summary of the invention
It is an object of the invention to provide and a kind of in conventional projector, realize optical projection imaging, method and device that video frame sync shows and measures, the method achieve the combination of tradition and modernity, improve the technology content of traditional instrument, extend the range of traditional instrument, and then enhance the market competitiveness of traditional instrument.The most both all functions of original projector had been remained, being simultaneously achieved again the simultaneous display of CCD video image, process, conventional art combines with modern technologies, it appears directly perceived, convenient, fast and have class, improve measurement efficiency simultaneously, alleviate the labor intensity of operator.
nullThe purpose of the present invention and solve its technical problem underlying and realize by the following technical solutions: a kind of projector imaging、The method that video frame sync shows and measures，Measured workpiece is arbitrarily put on instrument workbench，By object lens, measured piece profile is zoomed into picture，Design an objective lens including prism and fall times object lens，The part making light images in on rice wordline projection screen directly through this objective lens，Another part light is then diverted through dropping times object lens by this objective lens and images in CCD photosurface，By software and hardware, the image on CCD photosurface is shown the most in real time、Process，When observing image with projection screen，Computer screen also can show observed image simultaneously，The most both all functions of original projector had been remained，It is simultaneously achieved again the simultaneous display of CCD video image、Process.
The device that above-mentioned projector imaging, video frame sync show and measure, including computer software and hardware and laboratory glass wares workbench, glass table is arranged below transillumination group, and glass table is arranged above with half-reflecting half mirror, and the half-reflecting half mirror right side is provided with indirect illumination group；Half-reflecting half mirror is arranged above with objective lens, and the objective lens right side is provided with fall times object lens and CCD receptor surface, and objective lens is arranged above with illuminator A, illuminator A reflection position and is provided with illuminator B, illuminator B reflection position and is provided with band rice wordline projection screen.
During use, measured workpiece is arbitrarily placed on laboratory glass wares workbench, by half-reflecting half mirror and objective lens, imaging is divided into two-way, one road vertical duction arrives a CCD receptor surface through fall times object lens, then by software and hardware, CCD video signal is sent to computer and is opened up an image window by computer and show the contour images of measured workpiece dynamically；Objective lens is the most directly passed through on another road, band rice wordline projection screen is arrived through illuminator A and illuminator B, image on the projection screen with rice wordline, so, one workpiece profile image images in on rice wordline projection screen and on computer screen simultaneously, both can observe measurement on projection screen, and automatic tracing-edge can have been realized with CCD video image again simultaneously and measure, it is achieved that conventional projector is measured and the combination of video measuring.
The present invention compared with prior art has clear advantage and beneficial effect.From above technical scheme, the present invention is to redesign an objective lens including prism in the optical system of design, with fall times object lens, the light beam towards projection screen is divided into two bundles, a branch of projection screen that leads directly to carries out tested part amplification, another is restrainted and carries out tested part image zoom for Computer display, process towards fall times object lens and CCD camera after the most diverted prism reduces light energy, thus achieve projection screen, audio video synchronization display processes, and is united two into one with video image measurement by projection measurement.Light path is divided into two, make workpiece profile image be imaged on respectively two different as side, achieve the synchronization that matching measurement is amplified in optical projection and CCD video image is measured, it is allowed to the measurement function both with conventional projector, there is again the function of CCD video measuring, improve the technology content of projector, extend the range of conventional projector, enhance the market competitiveness of conventional projector.
