Synchronization of Imaging

摘要

The invention relates to a method, the method comprises exposing an image frame of an object to be monitored by an area image sensor, transmitting a part of the exposed image frame to an image data processing device, analysing the part and if the part is detected to comprise a predefined event, said image data processing device is arranged to transmit a trigger signal for triggering said area image sensor so that said area image sensor transmits a bigger part of at least one further image frame to said image data processing device for further analysis, and if not the area image sensor continues to expose at least one further image frame and to transmit a part of said at least one exposed further image frame. The invention further relates to a machine vision system for performing the method and a computer program product comprising instructions to perform the method.

1. A method, comprising:
exposing an image frame of an object to be monitored by an area image sensor;
wherein the method comprises; transmitting a first image part of said image frame to an image data processing device; analysing said first image part by said image data processing device, wherein;
if said first image part is detected to comprise at least one predefined event, said image data processing device is arranged to transmit a trigger signal for triggering said area image sensor so that said area image sensor is reconfigured to expose at least one further image frame and to transmit a second image part of said at least one further image frame to said image data processing device for further analysis, wherein the second image part is a part of said at least one further image frame and wherein the second image part is bigger than the first image area part, andif said first image part is not detected to comprise a predefined event, said area image sensor continues to expose image frames and to transmit a first image part of said image frames to the image data processing device.
