Embodiment 1

[0030] A multi-TOF depth information acquisition synchronization system, such as figure 1 , 5 As shown, it includes several TOF sensors 100, a first control module 200 and a second control module 300 with the same number of TOF sensors;

[0031] The TOF sensor 100 is used to obtain the spatial position information data of each target, and transmit the spatial position information data of each target to the first control module;

[0032] The first control module 200 is used to accelerate the processing of the spatial position information data of each TOF sensor to obtain control coordinate information, and transmit the control coordinate information to the second control module;

[0033] The second control module 300 is configured to output a homologous shutter signal according to each control coordinate information, and feed back the homologous shutter signal to each of the first control modules, and each first control module according to the same The source shutter signal then gener...

Embodiment 2

[0038] A method for multiple TOF depth information acquisition synchronization, such as figure 2 As shown, including the following steps:

[0039] The TOF sensor acquires the spatial position information data of each target, and transmits the spatial position information data of each target to the first control module;

Abstract

The invention discloses a multi-set TOF (Time Of Flight) depth information acquisition and synchronization system, which comprises a plurality of TOF sensors, first control modules and second controlmodules, wherein the TOF sensors acquire space position information data of each target and transmits the space position information data of each target into the first control modules; the first control modules accelerate the space position information data to acquire control coordinate information and transmit the control coordinate information into the second control modules; the second controlmodules output a paronym shutter signal according to each piece of control coordinate information and feed back the paronym shutter signal into each first control module; and each first control modulegenerates each shutter signal according to the paronym shutter signal. According to the method and the device which are disclosed by the invention, the plurality of TOF sensors are fixed relative toa phase to realize synchronization of depth information generated by each first control module and then control the corresponding target according to the generated shutter signal through the first control modules, so as to realize synchronous treatment of the plurality of TOF sensors.

Description

Technical field [0001] The invention relates to the technical field of TOF ranging, in particular to a method and system for acquiring and synchronizing multiple TOF depth information. Background technique [0002] The Time of Flight (TOF) ranging method is two-way ranging technology or one-way ranging technology. Its realization process mainly uses the flight time between two asynchronous transceivers to measure the distance between nodes. . In the traditional TOF ranging technology, when the signal level is better modulated or in the non-line-of-sight line of sight, it is generally estimated based on the RSSI (Received Signal Strength Indication) ranging method, and the estimated result Ideal; and in the line-of-sight environment, at this time, the TOF-based distance estimation method can make up for the shortcomings of the RSSI-based distance estimation method. However, there are two key constraints in the TOF ranging method: one is that the sending device and the receiving ...
