Abstract

The invention relates to the field of machine vision, in particular to a non-contact spatial gesture intelligent lock system. Hardware of the system is sequentially connected with an image sensor, a register and a microprocessor, an output end of the microprocessor is connected with an input end of a touch display screen through a touch display screen interface, the image sensor is an CMOS (complementary metal oxide semiconductor) image sensor OV7670, image data acquired by the image sensor are 16-bit 565RGB format data, the register is a register AL422B, the microprocessor is a microprocessor STM32F103, and the touch display screen is a touch display screen ILI9325. The system has the advantages that the system is low in power consumption, simple in operation process, low in cost and late maintenance charge, high in safety, small in size, fine in functional expansibility and suitable for industrial popularization, and has wide market prospect and use values.

Description

technical field [0001] The invention relates to the field of machine vision, in particular to a non-contact space gesture intelligent lock system and an operating method thereof. Background technique [0002] With the large-scale commercialization of touch screen technology and the maturity of multi-point gesture touch, the multi-point gesture touch technology has become more and more popular in people's lives, but there are many problems that follow. For example, wear and tear and sanitation problems in the field of public services, such as the access control systems of some bank teller machines, are often touched by people. The sanitation problems and short service life of these switches have become the disadvantages of these systems. For some boxes used in special occasions, such as some boxes in the laboratory, using keys or touching the screen will affect the experimental process more or less in the experiment, and the switch is done through non-contact gestures. , sav...
