Embodiment 1

[0071] figure 2 A flow chart of the method for locating the cursor of the remote controller provided by Embodiment 1 of the present invention is shown, and for convenience of description, only parts related to this embodiment are shown.

[0072] The remote control cursor positioning method is mainly realized through the following steps:

[0073] In step S101, light spot images of multiple point light sources opposite to the remote control are collected.

[0074] In this embodiment, the position of the point light source is usually set in the direction of the display device (it can be a TV monitor or a computer monitor, etc.), specifically, it may be set on the frame of the display, or it may be set near the display device, and its position does not have to be strict. limit so that it can be imaged by the camera on the front of the remote control. In this step, the camera carried by the remote controller captures a frame of light point images, and each image contains several...

Embodiment 2

[0084] Figure 4 A flow chart of the method for locating the cursor of the remote controller provided by Embodiment 2 of the present invention is shown, and for the convenience of description, only the parts related to this embodiment are shown.

[0085] Since the light point image collected by the camera contains noise, this embodiment gives priority to corresponding processing on the image. The remote control cursor positioning method provided by this embodiment can be mainly realized through the following steps:

[0086] In step S201, light point images of multiple point light sources opposite to the remote controller are collected.

[0087] In step S202, denoising and binarization are performed on the spot image to obtain a processed spot image.

[0088] In step S203, the deflection angle of the camera of the remote controller is acquired according to the light spot image.

[0089] In step S204, the coordinates of the cursor of the remote controller in the coordinate sys...

Embodiment 3

[0094] Figure 5 A flow chart of determining the coordinates of the cursor in the display coordinate system provided by Embodiment 3 of the present invention is shown. For the convenience of description, only the parts related to this embodiment are shown.

[0095] This embodiment provides a better way to implement step S103 in the first embodiment above, and this embodiment is based on the fact that multiple point light sources are on the same straight line. Specifically, the coordinates of the cursor in the coordinate system of the display device can be determined by the following The method described above is implemented:

[0096] In step S301, determine the center of gravity of each light spot in the light spot image, and get the geometric center of the center of gravity of all light spots as the first coordinate of the cursor in the camera coordinate system;

[0097] In this embodiment, the coordinates of the center of gravity of the light spot are taken for correspondin...

Abstract

The invention is applicable to the field of cursor positioning and provides a remote control cursor positioning method, a remote control cursor positioning device, a remote control and a cursor positioning system. The remote control cursor positioning method comprises the following steps: acquiring light spot images of a plurality of point light sources opposite to the remote control; acquiring the deflection angle of a camera of the remote control according to the light spot images; and determining coordinates of a cursor of the remote control in a coordinate system of a display device according to the light spot images and the deflection angle. According to the technical scheme, the problem of cursor positioning deflection when the remote control rotates relative to the horizontal plane is solved; and when a user holds the remote control by hand, the posture is not fixed, so that the using freedom and the using comfort of the remote control are improved. The remote control based on the cursor positioning method and the cursor positioning system can well solve the problems that the conventional remote control or cursor positioning system has a single function and the positioning deflection is easily caused.

Description

technical field [0001] The invention belongs to the field of cursor positioning, and in particular relates to a remote controller cursor positioning method and device, a remote controller and a cursor positioning system. Background technique [0002] With the continuous introduction of large-screen display devices such as smart TVs and computers, people have higher and higher requirements for the flexibility of display cursor control. Especially in the field of smart TVs, the traditional TV remote control controls the cursor control signal by operating the buttons on the remote control, and can only realize page up, page down, OK, up, and down by repeatedly operating the up, down, left, and right buttons. , left, right and other operations, the cursor cannot be moved arbitrarily, and at the same time, the operation is very cumbersome, and in a dark environment, misoperations may occur due to inaccurate buttons. [0003] In order to solve the above problems, the prior art pr...
