Problems solved by technology

However, the real time stamp calibration requirements are related to exposure parameters such as the exposure start time, exposure end time, and exposure duration of the image, and only the time when a specific signal is sent is used as the time stamp, and the time stamp accuracy of the determined image is low.

Abstract

The embodiment of the invention discloses a method and device for determining an image time stamp. The method includes: when determining that an image acquisition device acquires an image, determining the time stamp of the image according to a predetermined image exposure parameter of the image acquisition device and determining a reference time when the image acquisition device acquires the image; wherein, the image exposure parameter is based on The unit column of the acquired detection image and the light-emitting unit in the light-emitting state in the carry column, as well as the set time interval and the number of cycles corresponding to the light-emitting unit of the carry column are determined; The image collected by the light-emitting unit; the light-emitting units of the unit column light up in sequence according to the set time interval when the marking equipment is working, and the light-emitting units of the carry column light up in sequence according to the cycle times that all the light-emitting units of the unit column complete the light-emitting cycle. By applying the solution provided by the embodiment of the present invention, the time stamp of the image can be determined more accurately.

Description

technical field [0001] The present invention relates to the technical field of automatic driving, in particular to a method and device for determining an image time stamp. Background technique [0002] With the development of science and technology, the application of image acquisition equipment is more and more extensive. For example, in the field of monitoring, detection, and automatic driving, the images collected by image acquisition equipment can provide data support for specific analysis. In practical applications, not only images are used, but also each image needs to be associated with real-world time for multi-dimensional decision-making operations. Accurately determining the real exposure time of an image is very important in some application fields, such as the field of automatic driving. [0003] The image acquisition device will send a specific signal when acquiring an image, and the moment when the image acquisition device sends the specific signal can be use...
