好ましくは、
前記照明手段の前記対象物に対する照明角度は、前記撮像手段の前記対象物に対する撮影角度より大きいように構成することが可能である。
このように構成することによって、良好に計測できる範囲を拡大することができる。
また、好ましくは、
前記撮像手段は、少なくとも2つの撮像装置を有し、当該少なくとも2つの撮像装置で前記撮影領域を撮影することによって視差を有する撮像画像を取得するように構成することが可能である。
また、好ましくは、
前記対象物は、パンタグラフのすり板であり、
前記対象物の計測は、前記すり板の形状又は前記すり板の摩耗量の計測であるように構成することが可能である。
Preferably,
The illumination angle with respect to the object of illumination means may be configured to be greater than the imaging angle relative to the object of the imaging unit.
By comprising in this way, the range which can be measured favorably can be expanded.
Also preferably,
The imaging unit may include at least two imaging devices and acquire a captured image having parallax by imaging the imaging region with the at least two imaging devices.
Also preferably,
The object is a pantograph grinder,
The measurement of the object can be configured to be measurement of the shape of the sliding plate or the wear amount of the sliding plate.

本発明によれば、天候によって計測精度が低下しない計測システムを提供することができる。 According to the present invention, it is possible to provide a measuring system in which measurement accuracy by weather does not decrease.

以上説明した実施形態1の計測システム100によれば、撮像手段(撮像部101)と照明手段(照明部102)は、線路203の側方に当該線路203に対して同じ側に設置され、照明手段(照明部102)は、すり板402,403を上方から照明し、撮像手段(撮像部101)は、当該撮像手段と照明手段(照明部102)との間に設定されている撮影領域205内ですり板402,403を上方から撮影するように構成されている。
したがって、雨などの天候に関わらず良好に計測することが可能である。また、線路脇から奥行き方向に斜めに配置された場合でも計測可能であるため、装置を線路脇に設置でき、設置コストの低減や車両運行中のメンテナンスが可能となる。また、同時に複数のすり板の摩耗量を計測することができ、設置個所の制約が低減できる。
具体的には、すり板を斜め上方から撮影し、複数列に配置されたすり板のエッジ箇所の位置を算出することで、1つの撮像手段及び1つの照明手段を用いた1回の撮影で同時に各すり板の両側の厚みを計測することができる。
また、撮像手段と照明手段を線路の側方に当該線路に対して同じ側に設置するとともに、撮像手段と照明手段との間に設定されている撮影領域内ですり板を撮影することで、すり板の上面と側面のコントラストが大きくなるので、計測誤差を低減できるとともに、すり板が濡れていても、乱反射の影響を低減でき、雨天時であっても計測精度向上が可能である。
また、1つの撮像手段及び1つの照明手段を用いた1回の撮影で各すり板の両側の厚みが計測可能であるため、複数列に配置されたすり板の内側の厚みも計測できることや、両側を計測するために撮影方向を変える必要がなく、システムの複雑化が低減できる。
また、線路脇から計測可能であるため、線路を跨ぐように設置する必要がなく、設置コストを低減できるとともに、システムのメンテナンスを線路の使用中(架線通電中や、車両運行中など)でも行うことができる。
According to the measurement system 100 of the first embodiment described above, the imaging unit (imaging unit 101) and the illuminating unit (illumination unit 102) are installed on the same side of the line 203 on the same side as the line 203. The means (illuminating unit 102) illuminates the sliding plates 402 and 403 from above, and the image capturing unit (imaging unit 101) captures an imaging region 205 set between the image capturing unit and the illumination unit (illuminating unit 102). The inner slats 402 and 403 are configured to be photographed from above.
Therefore, it is possible to measure well regardless of the weather such as rain. In addition, since measurement is possible even when arranged obliquely from the side of the track in the depth direction, the device can be installed on the side of the track, and installation costs can be reduced and maintenance during vehicle operation can be performed. In addition, the wear amount of a plurality of sliding plates can be measured at the same time, and the restrictions on the installation location can be reduced.
Specifically, by photographing the sliding plate from obliquely above and calculating the position of the edge portion of the sliding plate arranged in a plurality of rows, it is possible to perform one shooting using one imaging unit and one illumination unit. At the same time, the thickness of both sides of each sliding plate can be measured.
In addition, by installing the image pickup means and the illumination means on the same side of the track to the side of the track, and shooting the board in the shooting area set between the image pickup means and the illumination means, Since the contrast between the upper surface and the side surface of the sliding plate is increased, the measurement error can be reduced, and even if the sliding plate is wet, the influence of irregular reflection can be reduced, and the measurement accuracy can be improved even in rainy weather.
In addition, since the thickness of both sides of each sliding plate can be measured by one shooting using one imaging means and one lighting means, the thickness inside the sliding plates arranged in a plurality of rows can be measured, It is not necessary to change the shooting direction to measure both sides, and the complexity of the system can be reduced.
In addition, since it can be measured from the side of the track, it does not need to be installed across the track, reducing installation costs, and performing system maintenance even when the track is in use (while the overhead line is energized or the vehicle is operating). be able to.
