Moreover, decision mechanism 65 makes the brightness of the Y-axis line in the region of pawl 21 be averaged, the position of brightness change drastically is selected
(step S43) calculates the upside in the region of quadrangle pawl 21 and the gap (step S44) of hook 22.The detailed content of the computational methods
It is described in detail in aftermentioned Figure 13.
Decision mechanism 65 emphasizes gap width and the output of upside if the gap width abnormal (step S45 → Yes) of upside
(step S47) will not then emphasize the gap width of upside and export (step S46) if not so.If decision mechanism 65 is each
Gap width is then judged as exception more than regulation predetermined threshold.
Decision mechanism 65 emphasizes gap width and the output in left side if the gap width abnormal (step S48 → Yes) in left side
(step S50) will not then emphasize the gap width in left side and export (step S49) if not so.
Decision mechanism 65 emphasizes gap width and the output on right side if the gap width abnormal (step S51 → Yes) on right side
(step S53) will not then emphasize the gap width on right side and export (step S52) if not so.
By these outputs as a result, decision mechanism 65 can easily determine whether from the gap of the door lock 2 of a floor
It is abnormal.

Make the situation that brightness is averaged.The brightness value of X-axis line XII-XII is substantially 50% on hook 22, on the gap of left and right substantially
0%, substantially 100% on pawl 21.Brightness change is formed between left and right gap and pawl 21, between left and right gap and hook 22 drastically
Boundary.Therefore, it is possible to calculate left side gap width Gl and right side gap width Gr.
Figure 13 is to be related to falling into a trap from the image of the major part for the door lock 2 for shooting a floor counting at the gap width of side
The schematic diagram of reason.
Here, representing when pawl 21 is identified as substantially four border regions, decision mechanism 65 is attached in the XIII-XIII of Y-axis line
Closely make the situation that brightness is averaged.The brightness value of Y-axis line XIII-XIII is substantially 50% on hook 22, on the gap of left and right substantially
It is 0%, substantially 100% on pawl 21.It is anxious that brightness change is formed between upper side clearance and pawl 21, between upper side clearance and hook 22
Acute boundary.Therefore, it is possible to calculate upside gap width Gu.
Figure 14 is that medelling represents pawl rectangle 211 and upper side clearance rectangle 27, left side gap rectangle 25, right side gap rectangle
26 figure.
Pawl rectangle 211 represents the region when general shape by pawl 21 is identified as rectangle.
