Abstract
A radiation inspection apparatus is configured in such a way as to totalize pixels, whose gray levels represented by pixel gray level information, which is outputted from radiation detector, are within a preset gray level range of gray level profile from XL to XH, and to inspect from a result of the totalization whether or not a stockout of object occurs. Thus, the apparatus is enabled to correctly determine an occurrence of a stockout of the object by simple data processing without performing pattern recognition on a radiation perspective image.
Claims5
A radiation inspection apparatus comprising:
- a radiation generator for generating radiation toward an object to be inspected;
- a radiation detector, disposed in such a way to face said radiation generator, for detecting the radiation transmitted through the object to be inspected and outputting a pixel gray level information for each pixel consisting an image of the object to be inspected;
- and
- a data processor unit for performing data processing by using the pixel gray level information outputted from said radiation detector,
- wherein said data processor unit totalizes the number of pixels, whose gray levels represented by the pixel gray level information, which is outputted from said radiation detector, are within a predetermined gray level range, and determines from a totalization of the number of pixels whether or not a stockout of the object to be inspected occurs.
A radiation inspection method comprising:
- generating radiation toward an object to be inspected;
- detecting the radiation transmitted though the object to be inspected to obtain a pixel gray level information of each pixel consisting an image of the object to be inspected based on the detected radiation;
- totalizing the number of pixels, whose gray levels represented by the pixel gray level information are within a predetermined gray level range;
- and
- determining from a totalization of the number of pixels whether or not a stockout of the object to be inspected occurs.
