Apparatus for scanning a moving object includes a visible waveband sensororiented to collect a series of images of the object as it passes through a field of view. An image processoruses the series of images to form a composite image. The image processorstores image pixel data for a current image and a predecessor image in the series. It uses information in the current image and its predecessor to analyse images and derive likelihood measures indicating probabilities that current image pixels correspond to parts of the object. The image processorestimates motion between the current image and its predecessor from likelihood weighted pixels. It generates the composite image from frames positioned according to respective estimates of object image motion. Image motion may alternatively be detected by a speed sensor such as a Doppler radarsensing object motion directly and providing image timing signals.

Moving object scanning apparatus and method

Millimeter wave imaging apparatus for use, in articular, as an indoor security system to identify objects concealed under the clothing of a person in a background scene, including means for generating a millimetric temperature contrast between the person to be imaged and the surroundings in scene. This may be a &ldquo;hot&rdquo; or &ldquo;cold&rdquo; source for producing a flux, and a relatively smaller flux respectively, of incoherent millimeter wavelength radiation. The apparatus may also include at least one partial ellipsoid reflective enclosure for reflecting millimeter wavelength radiation emitted from the &ldquo;hot&rdquo; and &ldquo;cold&rdquo; source so as to generate non-localized and uniform illumination of the person. The enclosure may have a metallic inner surface on which a dimpled pattern may be embossed to diffuse the millimeter wavelength radiation reflected from the metallic inner surface. The apparatus also includes one or more millimeter wavelength imaging cameras for detecting the millimeter wavelength radiation at one or more millimeter wave center frequencies, which may be mounted inside or outside the reflective enclosure. An image of the objects may be generated on a television monitor from the detected radiation.
