Virtual secondary projection touch-tone elevator call system and use method thereof

Abstract

The invention discloses a virtual secondary projection touch-tone elevator call system and a use method thereof. A traditional elevator physical key control panel can be abandoned, a brand new virtualprojection key is adopted based on the projection technology to achieve elevator calling and can be projected to an appropriate height according to stature information of a user, meanwhile, during operation, the ideal key is preliminarily determined by positioning the finger of the user, then a key projection in the local area is amplified, on one hand, the user conveniently operates the ideal key quickly without making errors easily, misoperation is prevented, on the other hand, by increasing the area of the key projection and reducing the number of key projections, the difficulty of subsequent image processing and key recognition can be obviously reduced, the recognition efficiency and accuracy are improved, the problems that traditional physical keys are easy to damage and inconvenientto use are solved, applications are more diverse, installation and maintenance are convenient, more durable service is achieved, there is no need to change existing key habits of the user, and the system can be conveniently and directly put into use.

Description

technical field [0001] The present invention relates to the technical field of electronic technology, and more specifically, to a virtual re-projection button call system and a method for using the same. Background technique [0002] Elevator refers to the permanent transportation equipment that serves several specific floors in the building, and its car runs on at least two rigid rails that are perpendicular to the horizontal plane or at an inclination angle of less than 15° from the plumb line. There is also a step type, and the tread plate is installed on the crawler belt to run continuously, commonly known as an escalator or a moving walk. Fixed lifting equipment serving specified floors. A vertical elevator has a car running between at least two vertical or inclination angles of less than 15° rigid guide rails. The size and structure of the car are convenient for passengers to enter and exit or to load and unload goods. It is customary to use elevator as a general te...

Problems solved by technology

[0006] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a virtual re-projection button-type call elevator system and its use method, which can realize the abandonment of the traditional elevator physical button control panel and adopt a new virtual call system based on projection technology. The projection button realizes the elevator call, which can be projected to a suitable height according to the user's height information. At the same time, the ideal button is initially judged by locating the position of the user's finger during operation, and then the button projection in the local area is enlarged. On the one hand, it is convenient. Users can quickly and easily operate the ideal button to prevent misuse. On the other hand, by increasing the button projection area and reducing the number of button projections, it can significantly reduce the difficulty of subsequent image processing and button recognition, improve recognition efficiency and accuracy, and solve the problem of The problem of traditional physical keys being fragile and inconvenient to use, the application is more diverse, easy to install and maintain, and more durable, and it is easy to put into use directly without changing the user's existing key habits
