Abstract
An image processing apparatus has a trigger receiving section for receiving an external trigger and a trigger generation section including a timer. When a trigger from the outside is inputted, in synchronization with this trigger, the timer of the trigger generation section operates and a predetermined number of internal triggers are generated at predetermined intervals. After each image pickup data picked up by the external trigger and the internal triggers is processed by an image processing section statistical processing is internally performed by a statistical processing section and the maximum value, the minimum value, the average value, etc. of variations in the workpiece are calculated and the results are outputted.
Claims12
An image processing system comprising:
- a camera for picking up a workpiece;
- and
- an image processing apparatus for capturing image pickup data of the workpiece picked up by said camera and performing image processing, said image processing apparatus including a trigger receiving section for receiving a trigger from an outside to initiate capture of workpiece image pickup data by said camera, a trigger generation section for generating a predetermined number of internal triggers at predetermined intervals via an interval timer after said trigger receiving section receives the trigger from the outside, each of the internal triggers initiating capture of workpiece image pickup data at the predetermined intervals, an image processing section for performing image processing with respect to each of the image pickup data picked up by the camera after receipt of the trigger from the outside and the internal triggers, and a statistical processing section for calculating variations between the image pickup data picked up by the camera after receipt of the trigger from the outside and the image pickup data initiated by the predetermined number of internal triggers and for determining abnormal image pickup data that deviates from a predetermined range and eliminating the abnormal image pickup data from the statistical processing.
An image processing method comprising:
- receiving an external trigger from the outside to initiate image pickup processing of a workpiece;
- generating a predetermined number of internal triggers at predetermined intervals via an interval timer after receiving the trigger from the outside;
- picking up workpiece image pickup data by a camera after receipt of each of the external trigger and the internal triggers;
- performing image processing with respect to each of the workpiece image pickup data picked up by the camera after receipt of the external trigger and internal triggers;
- and
- performing statistical processing to calculate variations between the image pickup data picked up by the camera after receipt of the external triggers and the internal triggers, and determining abnormal image pickup data that deviates from a predetermined range and eliminating the abnormal image pickup data from the statistical processing.
