Problems solved by technology

For example, the user uses two light sources arranged horizontally as reference objects, and moves the mouse in the air from left to right. When light source A is used as the reference object, the image coordinates of the last frame of positioning image generated are (120, 0); After the mouse moves slightly to the right, the first frame of positioning image generated with light source B as the reference object is (120, 317). After comparing the two image coordinates, the output coordinate change data is column coordinate +317, according to The coordinate change data, the cursor on the screen will move 317 pixels to the left, which is inconsistent with the moving direction and distance of the air mouse, so there is no way to increase the moving length of the cursor by increasing the light source (reference object)

Embodiment 1

[0067] This embodiment provides an air mouse. like figure 1 As shown, the air mouse includes a casing 200 , a lens 202 disposed in the middle position of the front end of the casing 200 , and a circuit part in the casing 200 . The circuit part includes an image sensor module and a processing unit connected to the lens 202 .

[0068] The lens 202 and the image sensor module together form an image acquisition unit, wherein the lens 202 is a filter lens, capable of filtering out visible light and allowing only infrared light to pass through. The image sensor module is an OV7620 image sensor module, which integrates a CMOS image sensor and a DSP chip, and forms a complete infrared digital camera module with the lens 202, which can capture infrared light-emitting objects and output digital images.

[0069] The processing unit selects the STM32F407 chip of STMicroelectronics, and the output end of the OV7620 image sensor module is electrically connected to the input pin of the STM...

Embodiment 2

[0177] This embodiment provides an air mouse, which can simultaneously increase the moving length of the cursor in the horizontal and vertical directions.

[0178] To achieve this, at least two infrared light sources are required as references. On a rectangular board with a length of 25CM and a height of 15CM, an infrared light-emitting diode is placed in the upper left corner and the lower right corner. The two infrared light-emitting diodes have different brightness, and the image formed in the positioning image has different pixel values. For example, the image formed by the infrared light emitting diode in the upper left corner has a pixel value of 50 for each constituent pixel, and the image formed by the infrared light emitting diode in the lower right corner has a pixel value of 100 for each constituent pixel.

[0179] The difference between the air mouse of this embodiment and the one recorded in Embodiment 1 lies in the processing method of the positioning image by t...

Embodiment 3

[0192] This embodiment provides an air mouse. Compared with the first embodiment, step 1 of the image processing method adopted by the processing unit is different.

[0193] The air mouse of this embodiment and two light sources with different light emitting areas form an air mouse system.

[0194] The two light sources in this embodiment have different light-emitting areas, and the implementations of the two light sources are as follows Figure 9 As shown, there is a small light source 303 on the left edge of the front of the rectangular support 300, and a large light source 304 on the right edge. The light-emitting area of ​​the small light source 303 is 2 square millimeters, and the light-emitting area of ​​the large light source 304 is 4 square millimeters. There are infrared light-emitting diodes between the two light sources, and the distance between them is 20 cm.

[0195] The images formed by the two infrared light sources in the positioning image are composed of dif...

Abstract

The invention discloses an image processing method for an air mouse, the air mouse applying the image processing method and an air mouse system. The air mouse system comprises an air mouse and at least two light sources with different characteristics, wherein the air mouse comprises a shell, an image acquisition unit and a processing unit; the image acquisition unit shoots the light sources and outputs positioning images, and the light sources with different characteristics form different light source images in the positioning images; the processing unit forms different image codes according to the different images, compares the image positions and the image codes of the light source images in the front frame and the rear frame of the positioning images respectively, and outputs coordinate change data according to comparison results.

Description

technical field [0001] The invention relates to the field of computer and video game control, in particular to an image processing method for an air mouse, an air mouse and an air mouse system using the image processing method. Background technique [0002] The mouse is the most common computer and electronic game control device, and its main purpose is to control the movement of the cursor on the screen of display devices such as televisions and monitors. The cursor generally refers to the mouse pointer on the screen, the weapon crosshair in the video game, the character's field of view, the character and other icons that move with the movement of the mouse. [0003] Movement accuracy and movement length are two important aspects to measure mouse performance. The movement accuracy refers to the minimum number of pixels that can control the cursor movement on the screen when the mouse is moved in one direction; the movement length refers to the maximum number of pixels that...
