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 an image timestamp determination method and device. The method comprises the steps: determining a timestamp of an image according to a predetermined image exposure parameter of the image acquisition device and a reference moment when the image acquisition device acquires the image when determining that the image acquisition device acquires the image, wherein the image exposure parameters are determined according to the obtained light-emitting units in the light-emitting state in the unit column and the carry column of the detection image and the cycleindex corresponding to the light-emitting units of the set time interval and the carry column, the detection image is an image acquired by the image acquisition device for a plurality of light emitting units of the target plate device, the light-emitting units of the unit columns are sequentially lightened according to set time intervals when the target plate equipment works, and the light-emitting units of the carry columns are sequentially lightened according to the number of cycles of light-emitting cycles completed by all the light-emitting units of the unit columns. By applying method disclosed in the solution provided by the embodiment of the invention, the timestamp of the image can be determined 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...
