Abstract

The invention discloses a method, a device and equipment capable of identifying the distance of a line formed by image sensors, which belongs to the technical field of image communication, such as TVs. The method comprises the steps as follows: Step 1, determining the location of a corresponding pixel of an object to be tested, which is in a pixel array of each image sensor; Step 2, according to the positioned pixel location, calculating an angle between each image sensor and the object to be tested; and Step 3, according to the angle between each image sensor and the object to be tested and the size of the profile of equipment in a line distance relationship with the object to be tested, and determining a distance of a line between the image sensor of the equipment and the object to be tested. The method overcomes the defect in the prior art that equipment with a human-computer interaction function cannot effectively identify the distance of a line formed by the object to be tested and the image sensor during human-computer interaction, so as to improve a user's operation experience.

Description

technical field [0001] The invention belongs to the technical field of image communication, such as television, and in particular relates to a method, device and equipment for identifying the distance formed by a line with an image sensor. Background technique [0002] Smart TV has a fully open platform and is equipped with an operating system. Users can install and uninstall programs provided by third-party service providers such as software and games by themselves, and can surf the Internet through network cables and wireless networks. Smart TV conforms to the trend of high-definition, networked and intelligent TV sets. In addition to traditional TV reality screens and display drivers, smart TVs also include high-performance computing processor chips, channel source decoding chips, image and data processing chips, high-speed large-capacity storage media, and high-speed data transmission interfaces. Therefore, from the perspective of information technology, smart TV is not...
