An embodiment
See also Fig. 1, the structural representation that it shows a kind of monitoring device that the application provides can comprise: image acquisition device 100 and single-chip microcomputer 200.Wherein,
In the present embodiment, image acquisition device 100 can be bold and unconstrained prestige OV(OmmiVision for model, imageing sensor) 7670 digital camera.
Single-chip microcomputer 200 connects with image acquisition device 100, is used for repeatedly receiving image information, chooses the pixel region that coordinate figure changes in the image information, and pixel region is carried out mathematics manipulation, calculates count information.
In the present embodiment, the complete parts of images information of image acquisition device 100 every collections, and when parts of images information is sent to single-chip microcomputer 200, the capable sync cap of image acquisition device 100 produces a high level, and namely the I/O interface of the single-chip microcomputer 200 of the capable sync cap of corresponding connection this moment image acquisition device 100 is high level.When the I/O interface that single-chip microcomputer 200 detects the capable sync cap that connects image acquisition device 100 was high level, single-chip microcomputer 200 produced once that row interrupts, and then receives the parts of images information of image acquisition device 100 transmissions.Until after image acquisition device 100 sends last parts of images information, the frame synchronization interface of image acquisition device 100 produces a high level, namely the I/O interface of the single-chip microcomputer 200 of the frame synchronization interface of corresponding connection this moment image acquisition device 100 is high level, when the I/O interface that single-chip microcomputer 200 detects the frame synchronization interface that connects image acquisition device 100 is high level, single-chip microcomputer 200 produces a frame and interrupts, representing that current all image informations have gathered finishes, single-chip microcomputer 200 cuts out row interruption and frame interruption subsequently, and all parts of images information that the image acquisition device 100 that receives sends are processed.In the present embodiment, single-chip microcomputer 200 can be MSP(Mixed Signal Processor for model, mixed-signal processor) 430 single-chip microcomputer.
Wherein, image acquisition device 100 gathers image information according to predefined times of collection.For example, set image acquisition device 100 and according to 640 * 480 mode image information is gathered, wherein, 640 is that image acquisition device 100 is each gathers 640 pixels, and 480 is that the times of collection of image acquisition device 100 is 480 times.Single-chip microcomputer 200 gathers after receiving all parts of images information of the collection that image acquisition device 100 sends, all pixels is transformed under the same projected coordinate system, and calculate the wherein coordinate figure of each pixel.
After a period of time, image acquisition device 100 begins the Resurvey image information again, and single-chip microcomputer 200 receives the image information that image acquisition device 100 sends again, and image information is carried out same processing again, calculates the coordinate figure of each pixel this moment.By contrasting the variation of the coordinate figure of pixel in twice image information, draw the pixel region that coordinate figure changes, and then the pixel region that coordinate figure changes is carried out mathematics manipulation, calculate the count information of student's total number of persons in the classroom.Especially, the pixel region that changes of coordinate figure is the zone that has the student.
Please in conjunction with Fig. 2 and Fig. 3, wherein, Fig. 2 shows the structural representation of the image acquisition device of a kind of monitoring device that the application provides, and Fig. 3 shows the structural representation of the single-chip microcomputer of a kind of monitoring device that the application provides.
