Description

Automatic optical detection device

The present invention relates to an automatic optical detecting device for a finger peak, and more particularly to a device for automatically detecting a peak of a gesture image captured by an image capturing device.

According to the various consumer electronic products, the touch device with the input interface in an intuitive handwriting manner is quite popular. At present, the touch handwriting function commonly used in various consumer electronic products is not achieved through a stylus pen, but through a handwriting or a touch screen, but such a touch handwriting function is often emphasized because the consumer electronic product itself is convenient to carry. Sexuality has a limitation on the overall size, so that the touch device of handwriting input must be limited to the size of the consumer electronic product itself, causing troubles in handwriting input.

Therefore, the present author has created a creation to provide a video camera to capture gestures and detect fingers in view of the lack of actual implementation of the handwriting input device currently used in consumer electronic products. The position and number of peaks are used to input the detected peak data into a simple numerical or English code to provide control to the consumer electronics for related operations.

The main purpose of this creation is to provide an automatic optical detection device for the peaks, which uses the video lens to capture gestures and detect the position and number of the peak coordinates for the relevant industry to obtain the peak data according to the detection. Used in consumer electronics to control related handwriting operations.

The main purpose and effect of the above creations are achieved by the following specific technical means:

An automatic optical detecting device for a peak, comprising a hand image capturing unit, a hand image processing unit and an image output unit; the hand image capturing unit and the image output unit and the hand image processing unit The hand image processing unit includes a skin color binarized image processing module, an image appearance processing module, a hand region calibration processing module, and a finger peak detecting module; The hand image captured by the hand image capturing unit is transmitted to the hand image processing unit, and the skin color binarized image processing module of the hand image processing unit performs the skin color and the background in the hand image. Binary separation, and then the image processing module performs noise filtering or image simplification processing, and then the hand region calibration processing module calibrates the hand region, and then passes the finger peak detection module. Find the coordinates of the peak position, and finally find the gesture image of the peak coordinates in the image output unit output display.

The automatic optical detecting device of the finger peak as described above, wherein the hand image capturing unit is a video lens or a camera.

In order to make the technical content, creative purpose and the effect achieved by this creation more complete and clear, please elaborate below, and please refer to the drawings and drawings:

Please refer to the first figure, which is a schematic diagram of the architecture of the automatic optical detection device of the fingertip of the present invention.

The automatic optical detection device of the fingertip of this creation includes:

a hand image capturing unit (1) for capturing a hand image, wherein the hand image capturing unit is a video camera or a camera;

The first-hand image processing unit (2) is configured to pass the hand image captured by the hand image capturing unit (1) through skin color segmentation, binarization, image appearance processing, edge detection, and palm area calibration. After the palm center of gravity calibration and palm edge recording processing, the finger peak coordinates are obtained; wherein the hand image processing unit (2) includes a skin color binarized image processing module (21) and an image appearance processing. The module (22), the one-hand area calibration processing module (23) and the one-finger detection module (24); that is, the hand image captured by the hand image capturing unit (1) enters the skin color binarization The image processing module (21) performs the determination and binarization processing of the skin color block, and then enters the image appearance processing module (22) to perform noise filtering and disconnection operations, so that the image is simplified and the contour is smoother, and Obtain a hand edge image, and then use the hand area calibration processing module (23) to perform hand palm area calibration of the hand edge image, complete the palm area calibration, and then perform palm center of gravity calibration, and then pass the After the peak detection module (24) selected record palm edge coordinates refer to the peak, then the peak coordinate output means and to the image output unit (3) displays.

Accordingly, the position and number of the peaks can be detected by the automatic optical detecting device of the creative finger peak, and the device can be further applied to the lens ratio gesture for simple digital or English character input interface operation. The industry of related electronic products such as methods.

The above are only some of the examples of this creation, and are not intended to limit the creation of this creation. It should be included in the scope of this patent, based on the creative spirit and characteristics of this creation.

In summary, the present embodiment can achieve the expected use efficiency, and the specific structure disclosed therein has not been seen in similar products, nor has it been disclosed before the application, and has fully complied with the provisions of the Patent Law. And the request, the application for a new type of patent in accordance with the law, please forgive the review, and grant the patent, it is really sensible.
