Target-tracking-based remote controller and remote control method thereof

Abstract

The invention discloses a target-tracking-based remote controller. A receiver and two invisible light point sources are arranged at the terminal of an intelligent television. The remote controller comprises an image acquisition module, an image processing module, a cursor determination module, a transmitting module, a control module and a power module, wherein the image acquisition module is used for acquiring the data of the invisible light point sources; the image processing module is used for performing variedness filtering removal and binaryzation on the acquired data so as to obtain binary light point image data; the cursor determination module is used for calculating the center coordinate of each light point and transmitting the numbers of the acquired light points to the control module to be processed; the coordinates are transmitted to the terminal of the intelligent television through the transmitting module after cursor determination; the receiver at the terminal of the intelligent television is used for receiving and processing the cursor coordinates so as to obtain HID (hide) mouse data, thereby performing control. The target positioning in a direct tracking manner is performed through the two invisible light sources fixed on the intelligent television, so that the remote controller is simple and high in positioning precision. The invention further discloses a corresponding remote control method.

Description

Technical field [0001] The invention relates to the technical field of remote controllers for smart TVs, in particular to a remote control based on target tracking and a remote control method thereof. Background technique [0002] With the gradual introduction of smart TVs such as GoogleTV based on the Android operating system, traditional remote controls for program menus can no longer meet people's needs. The traditional TV remote control relies on repeatedly pressing the cursor control button in a fixed mode to provide cursor control functions such as up, down, left, and right. The cursor cannot be moved arbitrarily, and in the case of low light, the keys are not easy to distinguish, easy to press wrongly, and the operation is complicated. The most important thing is that the current smart TV is the embodiment of the smart terminal after the integration of the three networks, and the traditional remote control seems to be incapable of smart TV. Therefore, in order to facilit...

Problems solved by technology

[0003] The existing remote controllers with mouse function mainly use gyroscope sensors or gravitational acceleration sensors to achieve air positioning. The algorithm development of this solution is difficult, the cost is relatively high, and the positioning effect for small targets is relatively large. very poor
