In step 105, the spy of the characteristic area positional information of the normal pictures that will be preserved and current determination
Levy zone position information to compare, determine displacement compensation amount.The displacement compensation amount generally comprises transverse axis position
Difference, longitudinal axis positions difference and anglec of rotation difference.
In step 106, identified displacement compensation amount is stacked with the screw zone position information for having preserved
Plus, obtain currently absorbing picture and tighten up a screw the positional information in region, output screw area image.
In step 107, picture equalization, two-value are carried out to the current picture area image of tightening up a screw that absorbs
Change pretreatment.
In step 108, the pattern of spot detection is set as soft threshold values pattern, polarity set is white with black
Point (black screw background, shape of threads white), connection sexual norm is set as gray scale, filling, sets chi
Very little area is that, more than 200, quantity is 1.This step can also be first carried out in advance, with step 101 to 107
Without fixed precedence relationship.
In step 109, the current picture area image of tightening up a screw that absorbs is carried out by spot detection method
Detection, screw head texture image (cross of screw head or a word texture shadow are obtained if do not detected
Picture), then into step 110, judge the mobile terminal screw detecting exception；If detection obtains screw
Head texture image, then into step 111, judge that the mobile terminal screw detecting passes through.
By the visible detection method, without artificial participation, regarding for screw can be completed rapidly and accurately
Feel detection.Cost of labor can be effectively reduced, shortens detection time, at utmost reduce missing inspection and flase drop
Probability.And the accuracy of vision-based detection can be ensured.
