Time synchronization method, image processing method and object scanning system

Abstract

The embodiment of the invention relates to the technical field of image processing, and discloses a time synchronization method, an image processing method and an object scanning system. The time synchronization method is applied to the shooting device, and comprises the following steps: sending a query instruction to a server, and obtaining the time when the shooting device sends the query instruction as first time; the time when response information corresponding to the query instruction returned by the server side is received is recorded as second time, the response information comprises third time, and the third time is the time when the server side receives the query instruction; and obtaining a time deviation value between the shooting device and the server based on the first time, the second time and the third time. According to the invention, only the time deviation value between the shooting device and the server needs to be stored in the shooting device, the high-delay operation for adjusting the time of the shooting device is removed, the speed is higher, the efficiency is higher, and higher time synchronization precision can be achieved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of image processing, and in particular to a time synchronization method, an image processing method, and an object scanning system. Background technique [0002] With the rapid development of electronic devices represented by mobile phones and tablets, depth lenses capable of obtaining depth data have also become commonly used cameras in electronic devices. When scanning an object, a single depth lens can scan a static object to obtain a three-dimensional model; multiple depth lenses obtain a three-dimensional model of the object through rapid exposure one by one. Among them, the object scanning of multiple depth lenses is generally based on active structured light technology. In order to avoid mutual interference during exposure of multiple depth lenses, a high-speed hardware synchronization line will be set between multiple depth lenses to control the multiple depth lenses. Exposure ...

Problems solved by technology

However, modifying the system time of the depth lens requires very high operating authority, which is difficult to achieve, and even if the authority to modify the system time can be obtained, the time difference between the system times of multiple depth lenses is large, which cannot meet the high-precision scene requirements
