Multi-TOF camera combined work anti-interference method, TOF camera and electronic equipment

Abstract

The embodiment of the invention discloses an anti-interference method for joint work of multiple TOF cameras, the TOF cameras, electronic equipment and a computer storage medium. The method comprisesthe following steps: S102, obtaining a random code, wherein the random code is time delay before single image data acquisition in a current frame is completed; S104, starting timing of preset time according to the random code; S106, after timing of preset time is finished, carrying out image data collection operation, and the image data collection operation comprises laser emission operation and exposure operation; and S108, repeatedly executing the step S102S106 according to a preset number of times until the image data acquisition of the current frame is completed. According to the method, the TOF is taken as a main body, and the work of the camera is controlled from the single laser level of each frame of image, so that the probability of mutual interference generated when multiple TOFcameras work at the same time is reduced, the improvement on camera hardware is avoided, and the cost is reduced.

Description

technical field [0001] Embodiments of the present disclosure relate to the technical field of camera ranging, and in particular to a method for preventing mutual interference of multiple TOF cameras, TOF cameras, electronic equipment, and computer storage media. Background technique [0002] TOF is the abbreviation of Time of Flight (Time of Flight) technology, that is, the light emitted by the camera hits the surface of the object, and the light is reflected back and received by the sensor. The distance of the object to be photographed is calculated by calculating the time difference between light emission and reception to generate depth information. Compared with the traditional methods based on binocular distance measurement or structured light distance measurement, TOF distance measurement has the advantage of being less affected by ambient light and has no requirements for surface texture features of objects. [0003] At present, the technology of using TOF cameras to m...

Problems solved by technology

[0004] However, there are two problems in the prior art: 1. It is necessary to set up a network cable between TOF cameras with large volume and high power consumption or carry out position layout to realize wireless networking so that each TOF camera has an Ethernet communication function. Increase the cost, and for many scenarios this technology cannot be applied

2. Since the synchronization accuracy of the network clock synchronization technology is far lower than the laser working timing accuracy of the TOF camera, this method cannot control the work of the TOF camera from the laser level, and can only control the timing of multiple TOF cameras through the image frame level, making many The above scheme cannot be applied to scenes that require image splicing and matching
