Embodiment Construction

[0024] figure 1 A schematic diagram of an implementation example of the present invention is given. It includes a projector 1 , a host computer 3 , a digital camera 2 and a control panel 4 . Wherein, the control panel 4 is connected to the host 4 through a USB data cable, the digital camera 2 is connected to the host 4 through a USB data cable, and the projector is connected to the host through a VGA data cable.

[0025] Such as figure 2 As shown, assuming that the detected object is when the user 9 has just filled in a certain document, the placement method is as follows figure 2 As shown, the document to be detected 5 is placed in the detectable area 7 . At the same time, it is assumed that the detection task is to detect whether the user has marked "×" in all the small boxes on the document. At this time, there are 4 lines in the small boxes, and each line has 2. The small box shown in 202 is filled with "×", if 201 is not filled, then 201 is the special detection poi...

Abstract

The invention discloses a detection system of interactive projection and a detection method thereof, wherein the detection system comprises a projector, a host computer, a digital camera, a control panel and a detection platform. A detected object is positioned in the detectable area of the detection platform; the projecting area of the projector on the detection platform covers the whole detectable area of the detection platform; the vision area of the digital camera on the detection platform covers the projecting area of the projector on the detection platform; during the detection, the digital camera shoots the detected object positioned in the detectable area of the detection platform to obtain an image; the host computer recognizes a special detection point on the object to be detected; the projector marks the special detection point; and the user-operated control panel begins to modify the special detection point on the object, and then the marking information displayed by the projector is changed. The detection system is used for detection on deficiencies of articles such as electronic products, toys, files and the like, and is used in education and game.

Description

technical field [0001] The invention relates to a detection system, in particular to a detection system capable of real-time interactive projection and a detection method thereof. Background technique [0002] With the development of computer graphics, image and machine recognition technology, augmented virtual reality technology, one of the integrated technologies of the three, is gradually appearing in various application scenarios. This type of system usually consists of a visual camera part, a recognition software module located on the host computer, and a display part of an electronic screen (such as a flat-panel liquid crystal display, liquid crystal glasses or a liquid crystal helmet, etc.). The scenarios of such applications usually include the simulation of educational scenarios, industrial testing, advertising promotion, navigation, etc. When users use this type of system, because they must wear or hold this type of display device, when they need to interact frequ...
