Very little range is 252.8*178.5mm-644.2*388.4mm.
Further, analytical procedure includes: to carry out binary conversion treatment to picture and filter out interference；To having carried out at binaryzation
Picture after reason carries out open circuit transformation, is then filtered；Short-circuit change is carried out to the picture after binary conversion treatment has been carried out
It changes, is then filtered；By the picture for having carried out open circuit transformation post filtering processing and carry out at short-circuit transformation post filtering
The picture of reason merges, and is then analyzed.
Make picture show apparent black and white effect by carrying out binary conversion treatment to picture, highlights the wheel of silver wire
Exterior feature, by filtering out the influence that interfere can to avoid distracter to result.By open circuit transformation so that open circuit feature is more obvious, from
And be conducive to be filtered；By short circuit transformation so that short-circuit characteristic is more obvious, thus be conducive to be filtered,
After filtering processing, the short circuit of silver wire or open circuit portions stay on image because meeting the part of filtering condition, remaining is discontented
The part of sufficient filtering condition is filtered out, and by the picture for having carried out open circuit transformation post filtering processing and has carried out short-circuit transformation post filtering
The picture of processing merges, and analyzes with the presence or absence of bad, and can mark the undesirable position of silver wire.
A kind of working principle of the glass silver wire detection system 100 of the embodiment of the present application:
The desired guiding trajectory for selecting installation part 121 to move, control driving mechanism driving installation part 121 is according to desired guiding trajectory pre-
If plane motion, when sensor 172 detects that installation part 121 moves to predeterminable area, controller 171 controls light source 122 and sends out
Light and control camera 123 is taken pictures out, and sends photo to detection host, can compare on piece by detecting host
Silver wire is analyzed.Analysis includes: to carry out binary conversion treatment to picture and filter out interference；To having carried out the figure after binary conversion treatment
Piece carries out open circuit transformation, is then filtered；Carry out short-circuit transformation to the picture after binary conversion treatment has been carried out, then into
Row filtering processing；Will carry out open circuit transformation post filtering processing picture and carried out it is short-circuit transformation post filtering processing picture into
