Therefore, there is the image processing apparatus 40 involved by present embodiment the setting angle in video camera 30 to offset (i.e.,
Video camera 30 is mounted in a slanted state) in the case of the above-mentioned setting value relevant with image procossing (is carried out at shielding
The region of reason) it is corrected the function (following, to be designated as calibration function) of (adjust automatically).
The block diagram that Fig. 4 is constituted for the function of the image processing apparatus 40 of expression present embodiment.Here, main explanation with it is upper
The relevant function of calibration function is stated to constitute.
As shown in figure 4, image processing apparatus 40 include storage unit 41, it is image acquiring section 42, benchmark position extraction unit 43, poor
Divide calculating part 44, Correction process portion 45 and notifier processes portion 46.
The above-mentioned setting value relevant with image procossing is stored in storage unit 41.The setting value bag relevant with image procossing
Include the region (coordinate value) that should be located at as the doorframe in the region for being carried out shielding processing.In addition, in storage unit 41, in advance
First store the predetermined position (following, to be designated as reference position) as benchmark for benchmark position described later.Benchmark
Position is benchmark position of the video camera 30 in the photographs in the case of being installed exactly with predetermined setting angle
Position.
Image acquiring section 42 obtains the image (following, to be designated as photographs) photographed by video camera 30.
Benchmark position extraction unit 43 extracts the benchmark position that the photographs obtained by image acquiring section 42 includes.Base
Quasi- position is as the position for judging the benchmark whether setting angle of above-mentioned video camera 30 offsets, including such as hall
Side door sill and cage side door sill.In addition, hall side door sill and cage side door sill by such as aluminum oxide or
The situation of the formation such as stainless steel is more.Therefore, hall side door sill and cage side door sill, can compared with other positions
Easily extracted from photographs.
Position (in photographs of the Difference Calculation portion 44 at the benchmark position extracted by benchmark position extraction unit 43
Position) with the reference position that is stored in storage unit 41 it is inconsistent in the case of, calculate the position and benchmark position at the benchmark position
The difference put.In addition, the difference calculated by Difference Calculation portion 44 is represented such as with coordinate value.
Correction process portion 45 obtains the setting value relevant with image procossing stored in storage unit 41.Correction process portion 45
Corrected based on the difference calculated by Difference Calculation portion 44 the acquired setting value relevant with image procossing (for example, by
Implement the region of shielding processing).Setting value corrected, relevant with image procossing is stored in storage unit by Correction process portion 45
In 41.At the image that the setting value corrected, relevant with image procossing is performed when detecting the situation of above-mentioned hall 20
Used in reason.
Here, in the present embodiment, by correcting the setting value relevant with image procossing by Correction process portion 45, because
This, in that case of the setting angle skew of video camera 30, can also suppress the detection essence of the situation of hall 20
The reduction of degree.However, in the utilization of elevator device, sometimes due to the collision for example to cage 10 or video camera 30
Deng the setting angle of video camera 30 is further offset (that is, video camera 30 is tilted).
In this case, the situation that notifier processes portion 46 is offset the setting angle of video camera 30 is notified
(transmitting) gives the central monitoring position (manager) such as the utilization state of monitoring elevator device.In addition, for video camera 30
The situation that setting angle is offset, can be according to (that is, relevant with image procossing in correction in the utilization of elevator device
After setting value) whether the difference that is calculated again by Difference Calculation portion 44 is more than is correcting above-mentioned relevant with image procossing set
The difference that is calculated during definite value by Difference Calculation portion 44 is judged.
Next, the flow chart of reference picture 5, illustrate image processing apparatus 40 in the calibration function in present embodiment
Process step.In addition, the processing shown in Fig. 5 is performed such as before the utilization in elevator device.
First, image acquiring section 42 obtains the image (photographs) (step S1) photographed by video camera 30.
In benchmark position extraction unit 43, as the benchmark position in the photographs obtained in step sl, taken the photograph from this
Shadow image zooming-out such as hall side door sill and cage side door sill (region) (step S2).
Next, Difference Calculation portion 44 obtains the reference position stored in storage unit 41.Difference Calculation portion 44 is based on institute
The reference position of acquirement, judges whether the setting angle of video camera 30 offsets (step S3).In this case, Difference Calculation portion 44
According in the hall side door sill and the photographs of cage side door sill (benchmark position) extracted in step s 2
Whether position and reference position unanimously perform determination processing.Specifically, in hall side door sill and cage side door
In the case that position in the photographs of sill is consistent with reference position, it can determine that the setting angle for video camera 30 does not occur
Skew.On the other hand, the position in the photographs of hall side door sill and cage side door sill and reference position be not
In the case of consistent, it can determine that the setting angle for video camera 30 is offset.
In the case of the setting angle for being determined as video camera 30 is unmigrated ("No" in step S3), it is not necessary to correction with
The relevant setting value of image procossing, so processing terminates.
On the other hand, ("Yes" in step S3), difference in the case where the setting angle for being determined as video camera 30 is offset
Calculating part 44 calculates position and benchmark in the photographs of hall side door sill and cage side door sill (benchmark position)
The difference (step S4) of position.
Next, Correction process portion 45 obtains the setting value relevant with image procossing stored in storage unit 41.Correction
Processing unit 45 is corrected according to the difference calculated in step s 4 included by the acquired setting value relevant with image procossing
The region (region that doorframe should be located at) (step S5) for being carried out shielding processing.In the following description, for convenience, will
The region for being carried out shielding processing referred to as shielding area included by the setting value relevant with image procossing.
Herein, reference picture 6 and Fig. 7, specifically describe step S5.In addition, in Fig. 6 and Fig. 7 with it is above-mentioned
Fig. 3 identicals part, adds with Fig. 3 identicals reference to illustrate.Similarly, to the identical part in Fig. 6 and Fig. 7
Also mutually additional identical reference illustrates.
First, Fig. 6 shows that the setting angle in video camera 30 is taken the photograph in the state of not offseting (video camera 30 is not tilted) by this
One example of the image that camera 30 is photographed.
Reference position 400 shown in Fig. 6 represents the situation that video camera 30 is installed exactly with predetermined setting angle
Under benchmark position (hall side door sill 111 and cage side door sill 112) position.
In the image 310 shown in Fig. 6, hall side door sill 111 and cage side door sill 112 (boundary member)
Position and reference position 400 it is consistent, so can determine that the setting angle for video camera 30 is not offset.
Herein, as shown in fig. 6, the region of the doorframe 113 in such image 310 is consistent with shielding area 311.That is,
In the case of the setting angle of video camera 30 is unmigrated, shielding processing can be appropriately carried out to the region of doorframe 113.
On the other hand, Fig. 7 is represented in the state of the setting angle skew (video camera 30 is tilted) of video camera 30 by imaging
One example of the image that machine 30 is photographed.
In the image 320 shown in Fig. 7, hall side door sill 111 and cage side door sill 112 (boundary member)

Here, as shown in fig. 7, the region of doorframe 113 in such image 320 and shielding area 311 are inconsistent.Shielding
The doorframe 113 that region 311 is set in the case that video camera 30 is installed exactly with predetermined setting angle is located at
Region.However, in the case where the setting angle of video camera 30 there occurs skew, what the doorframe 113 in image 320 was located at
Region is offset from the position of shielding area 311.That is, in the case where the setting angle of video camera 30 there occurs skew, due to
The part of the unduplicated doorframe 113 of shielding area 311 and reflected light turns into interference light and produces influence, as described above, depositing
In the possibility for reducing the accuracy of detection of the situation of hall 20.
Therefore, in step s 5, Correction process portion 45 according to calculate in step s 4 difference (that is, represent relative to
The coordinate value of the inclination of hall side door sill 111 and cage side door sill 112 of reference position etc.), by shielding area 311
Position correction into consistent with the region of the doorframe 113 in image 320.In this case, Correction process portion 45 can also so that
The mode that shielding area 311 is deformed is corrected.
Fig. 5 is again returned to, corrected shielding area (shielding area after correction) in step s 5 is stored in storage
Deposit in portion 41 (step S6).
By using the shielding area after such correction, the setting angle even in video camera 30 there occurs that skew is such
In the case of, also can be in the image 330 photographed in the operation of elevator device by video camera 30 for example shown in Fig. 8

But benchmark position can also be the side in the hall side door sill and cage side door sill.As long as in addition, benchmark position
It is the position that can be extracted from photographs, then can also is the portion beyond hall side door sill and cage side door sill
Position.
In addition, in the step S3 shown in Fig. 5, as described above, according to hall side door sill and cage side door sill
Photographs in position it is whether consistent with reference position, judge video camera 30 setting angle whether offset.Even if however,
In the case where the setting angle of video camera 30 there occurs skew, as long as the skew (amount) is situation not to above-mentioned hall 20
The degree that impacts of accuracy of detection, then can also be the structure for not correcting the setting value (shielding area) relevant with image procossing
Into.That is, can also be according to the position in the photographs of hall side door sill and cage side door sill and reference position
Whether difference is in predetermined scope to perform step S3 processing, is not in the difference in predetermined scope
In the case of, it is determined as that the setting angle of video camera 30 is offset.
As described above, in the present embodiment, obtaining the image (photographs) photographed by video camera 30, calculating this and take
The position at the benchmark position that the photographs obtained includes and the difference of reference position (the predetermined position as benchmark),
The difference calculated according to this corrects the setting value relevant with image procossing.The setting value relevant with image procossing includes example
The region of shielding processing is such as carried out to the influence of image procossing in order to reduce interference light.In addition, being carried out shielding processing
