Embodiment Construction

[0025] The specific embodiments of the present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0026] A coaxial power data transmission device based on TOF module, such as figure 1 As shown, including TOF module module 1, interactive sub-module 2 and controller module 3, TOF module module 1 is provided with interactive sub-module 2, interactive sub-module 2 is provided with a coaxial connection device, TOF module module 1 It is connected with the controller module 3 through the interaction sub-module 2 . The power is supplied from the controller end to the TOF module end through the POC, that is, the interactive sub-module 2. After filtering out the AC signal through the inductance in the interactive sub-module 2, a relatively pure power supply is obtained to supply power to the module end. A coaxial cable is arranged between the TOF module module 1 and the controller module 3, and the data ...

Abstract

The invention discloses a coaxial line power supply data transmission device and method based on a TOF module, and the device comprises a TOF module module, an interaction sub-module and a controller module, a light source is driven to emit light in a square wave pulse modulation manner, and square waves with fixed frequency and fixed amplitude are output; configuration data are controlled to be transmitted in an inter-frame rest period in a cross transmission mode, and the influence of coupled noise on the transmission data is reduced. According to the invention, the wiring number of a TOF module transmission system is reduced through the coaxial connection device of the interaction sub-modules, the light source is driven to emit light in a square wave pulse modulation mode, the problems of low power consumption and miniaturization of the TOF module are solved, configuration data are controlled to be transmitted in an inter-frame rest period in a cross transmission mode, and the transmission efficiency is improved. The coupling noise influence of large current on transmission data in the POC transmission process is avoided, and the problem of data distortion in the POC transmission process is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of TOF, in particular to a coaxial power data transmission device and method based on a TOF module. Background technique [0002] TOF is the abbreviation of Time of flight, which literally means time of flight. In a broad sense, time-of-flight technology can be understood as a technology that further understands certain properties of ions or media by measuring the time it takes for objects, particles or waves to travel a certain distance in a fixed medium. 3D TOF module camera is a technical product of distance detection and 3D imaging created by the most advanced 3D stereo imaging technology. It has been widely used in consumer face recognition and in-vehicle FACE ID and OMS applications. Existing consumer and vehicle TOF modules often require long and cumbersome outlet and wiring methods, which greatly affects the aesthetics of the system layout and increases the difficulty of layout and installation cos...
