Abstract (en)

[origin: WO9630217A1] A label (100) for identification purposes, has a compact matrix of machine-readable cells (101-109) holding information and including the BCH error-correcting code. The cells may be binary, ternary (grey levels) or have more levels and may use colours. These labels are both easily detectable and accurately readable, because a plurality may occur within a single complex image captured outdoors, where adverse lighting and contaminants may detract from ideal conditions. Accordingly some (usually 4) characteristic cells (101, 102, 103, 104) per label are reserved for use as locators which, when found, indicate position, orientation and values on the scale of grey levels used in the symbol. A grey or white label perimeter may be used to determine intra-label lighting variations, as described in relation to the disclosed reading steps. One or more portable digital camera captures images and relays them to an analysis and decoding machine.
