Problems solved by technology

However, the time delay between capturing an image by a camera and sending it to the main controller is large and uncertain, which will cause a time gap between the time stamps of the images captured by each camera at the same time. High time synchronization cannot be guaranteed

Abstract

The embodiment of the invention discloses a data determination method and device and a vehicle-mounted terminal. Wherein the main controller is respectively connected with the at least two image acquisition devices, each image acquisition device is connected with the corresponding processor, and the main controller is connected with each processor. The method comprises the following steps: a maincontroller acquires an image acquired by each image acquisition device in response to a first image acquisition instruction, acquires a timestamp of the image sent by each processor, and associates the image with the timestamp according to a preset corresponding relationship between the image acquisition devices and the processors; wherein the first image acquisition instruction is used for indicating each image acquisition device to acquire an image at an associated moment; wherein the timestamp is determined when the processor determines that the image acquisition device acquires the image.By applying the technical scheme of the embodiment of the invention, the time synchronism among the images acquired by different cameras can be improved.

Description

technical field [0001] The present invention relates to the technical field of automatic driving, in particular to a data determination method, device and vehicle terminal. Background technique [0002] In the field of machine vision, a machine may require multiple cameras to collect images from different angles at the same time, and image processing on the images collected at the same time can form a relatively complete machine vision. The machine can be a vehicle or other smart devices, etc. [0003] In order to make multiple cameras on the machine collect multiple images at the same time, the main controller can send collection instructions to multiple cameras on the machine at the same time, each camera collects images when receiving the collection instructions, and sends the images to the main computer. controller. When the main controller receives the image sent by each camera, it determines the time stamp of the image (that is, image timing). In this way, multiple ...
