- the manual detection unit 17 presents the image to the operator and marks the image specified by the operator. For example, as shown in FIG. 3, an image being processed is displayed, and a seek bar 31 is displayed below the image. When the operator looks at the image, and if a characteristic image appears, such as a frame of tool exchange or a frame of ON/OFF of the machine light, marking is instructed.

- the machining program feature detection unit 14 detects blocks (lines) of the machining program that command the machine tool to perform a characteristic operation.
- a block that commands a machine tool to perform a characteristic operation is, for example, a block in which a specific M code or a code with a large amount of change in axis movement is described.
- a specific M code instructs discharge/stop of coolant, storage of tools, tool change, work change, and the like.
- the machining program feature detection unit 14 extracts from the machining program a block in which an M code for commanding such a characteristic operation is described.
- Codes with a large amount of change in axis movement are [1] parts where the movement of the axis is reversed, [2] parts where the movement direction of the axis changes more than the threshold value, and [3] where the speed changes greatly, such as from cutting feed to rapid feed. This is the part to do.
- the amount of change in axis movement is known from the machining program. In the machining program of FIG. 8, the movement of the axis is reversed in the block described as "X-10.”, which satisfies the condition [1]. In the block described as "Y10.", the moving direction of the axis changes from the X-axis direction to the Y-axis direction, satisfying the condition [2].
- the machining program feature detection unit 14 thus detects a block that commands the machine tool to perform a feature operation.
- the execution time calculator 15 calculates the execution time of each block of the machining program.
- Methods of calculating the execution time include a method of calculating mathematically, a method of calculating by simulation, a method of calculating by actual measurement, and the like.
- the mathematical calculation method uses the command coordinate values, the feed rate, and the parameter information of the numerical controller 100 written in the machining program.

As an example, the execution times of [1] 2nd line block "G01 X100.F200;” and [2] 3rd line block "G00 X200.;” are calculated. It is assumed that "rapid traverse speed: 10000 mm/min" is set for executing this machining program.
- the data linking unit 16 links the frames detected by the video feature detection unit 13 and the blocks detected by the processing program feature detection unit 14 .
- marks 1, 2 and 3 are marked. There are 1000 frames between mark 1 and mark 2. Assuming that the frame rate is 30 frames per second, it can be calculated that the interval between mark 1 and mark 2 is 33 seconds. The frame rate differs depending on the image compression method. Also, there are 2000 frames between mark 2 and mark 3 . Assuming that the frame rate is 30 frames per second, the time between mark 2 and mark 3 can be calculated as 66 seconds.
- Fig. 11 shows the relationship between the blocks of the machining program that command the machine tool to perform characteristic operations and the execution time.
- "M6” is a block that commands the machine tool to perform a characteristic operation of tool change.
- block A, block B, and block C are extracted as blocks that command the machine tool to perform characteristic operations.
- Block A describes "M6: Tool Change”
- Block B describes "M6: Tool Change”
- Block C describes "M9: Coolant OFF”.

- the execution time of the block on the first line is 5 seconds
- the execution time of the block on the second line is 5 seconds
- the execution time of the block on the third line is 10 seconds.
- the product of execution time and frame rate is the number of frames per block. In this way, frames and blocks are associated with each other.
- the data linking unit 16 uses the execution time to associate frames with blocks, and excludes frames with no link partner and blocks with no link partner. 11 and 12 are examples in which the number of blocks is greater than the number of marks. 10, there are three marking locations, namely mark 1, mark 2, and mark 3. In FIG. 16, four blocks, block A, block B, block C, and block D, are extracted.
- the data associating unit 16 uses the time between block A and block B as “13 seconds”, the time between block B and block C as “20 seconds”, and the time between block C and block D as “67 seconds”. Then, determine which mark matches which block. In this example, there is no mark corresponding to block B. Therefore, block B is not used for tying, and blocks A, C, and D where tying partners exist are used.

If the number of marked frames and the number of detected blocks match (step S7; YES), the process proceeds to step S9. If the number of marked frames and the number of detected blocks are different (step S7; NO), the numerical controller 100 compares the time of the marked frame and the time of the detected block, Frames and blocks are detected as marks and blocks that can be linked (step S8).
- the numerical controller 100 associates the frame detected in step S2 with the block detected in step S4 (step S9).
- the numerical control device associates blocks other than the blocks associated in step S9 with video frames using the block execution time and frame rate (step S10). As a result, all blocks of the processing program are associated with video frames.

Abstract
Description
また、特許文献1では、『処理対象である機械データに動画データが含まれている場合に、動画データのフレーム画像のうち、所定の事象を示す予め設定された特徴が表れているフレームの時点を抽出してもよい』と記載されている。特許文献1では、画像解析により、工具がワークに接触したタイミング、又は離れたタイミングが検出できる。
しかしながら、特許文献1の技術は、加工時に取得したデータと加工プログラムとを紐づけるものではない。
本開示の一態様である映像解析システムは、数値制御装置の加工映像を取得する映像取得部と、数値制御装置の加工プログラムを取得する加工プログラム取得部と、加工映像に含まれるフレームのなかで、特徴のあるフレームを検出する映像特徴検出部と、加工プログラムに含まれるブロックのなかで、特徴のある動作を工作機械に指令するブロックを検出する加工プログラム特徴検出部と、特徴のあるフレームと特徴のある動作を工作機械に指令するブロックとを紐づけるデータ紐づけ部と、を備える。
本開示の一態様である記憶媒体は、1つ又は複数のプロセッサが実行することにより、数値制御装置の加工映像を取得し、数値制御装置の加工プログラムを取得し、加工映像に含まれるフレームのなかで、特徴のあるフレームを検出し、加工プログラムに含まれるブロックのなかで、特徴のある動作を工作機械に指令するブロックを検出し、特徴のあるフレームと特徴のある動作を工作機械に指令するブロックとを紐づける、コンピュータが読み取り可能な命令を記憶する。
図1に示すように、本開示では、映像解析装置を、数値制御装置100に実装する。映像解析装置は、PC(パーソナルコンピュータ)、サーバ、携帯端末などの情報処理装置に実装してもよい。また、映像解析装置の構成要素をネットワーク上の複数の情報処理装置で分散処理する映像解析システム1000としてもよい。
映像特徴検出部13は、手動検出部17と自動検出部18とを備える。手動検出部17は、オペレータに映像を提示し、オペレータが指定した映像にマーキングを行う。例えば、図3に示すように、加工中の映像を表示、映像の下にシークバー31を表示する。オペレータが映像を見て、工具交換をしているフレーム、機内灯がON/OFFしたフレームなど特徴のある映像が出現すると、マーキングを指示する。図3のシークバーには、マーキングされた箇所を示すアンカー32が表示されている。
図4は、輝度変化の例である。輝度変化の例としては、映像全体の輝度が変化する場合と、特定の輝度値の割合が変化する場合と、注目領域の輝度が変化する場合がある。
映像全体の輝度が変化する例として、工作機械の機内灯のON/OFFがある。工作機械の機内灯は通常OFFである。オペレータが作業するときは、機内灯をONする。機内灯をONすると、機内全体が明るくなり、輝度が高くなる。逆に機内灯をOFFすると機内全体が暗くなり、輝度が低くなる。自動検出部は、映像全体の輝度が大きく変化したフレームを、特徴のあるフレームとしてマーキングする。
図5では、クーラントが吐出される注目領域51に設定している。ワークの加工時、すなわち、クーラントがONのときには、注目領域51に占めるクーラントの輝度の割合が多いが、クーラントをOFFにすると映像に占めるクーラントの輝度の割合が少なくなる。クーラントのON/OFFによって輝度が大きく変化する。自動検出部18は、注目領域の全ピクセルの輝度の変化量の総和と閾値とを比較し、注目領域の全ピクセルの輝度の変化量の総和が閾値を超えたときのフレームを、特徴のあるフレームとしてマーキングする。
特徴点の検出方法には、例えば、SIFT(Scale-Invariant Feature Transform)やSURF(Speeded-UP Robust Features)があるがこれに限定されない。SIFTやSURFは、物体のコーナ部分などを特徴点として検出する。
実測による算出では、実行中のブロック(行)の番号を一定周期で問い合わせ、ブロック番号が変化したタイミングで1ブロックの実行時間を記録する。シミュレーションによる算出では、シミュレーションソフトがブロックごとの実行時間を算出する。なお、実行時間の算出方法は、特開2020-38671号公報などにすでに開示された既存の技術である。
データ紐づけ部16は、紐づけたフレームとブロックとを基準として、残りのフレームとブロックとを対応付ける。対応付けにはブロックの実行時間を用いる。ブロックの実行時間とフレームレートから対応するフレームが算出できる。図10の例では、1行目のブロックの実行時間が5秒、2行目のブロックの実行時間が5秒、3行目のブロックの実行時間が10秒である。実行時間とフレームレートの積がブロックごとのフレーム数である。このようにして、フレームとブロックとの対応付けを行う。
図11と図12は、ブロックの数がマークの数よりも多い例である。図10の映像のマーキング箇所は、マーク1、マーク2、マーク3と3箇所であるが、図16では、ブロックA、ブロックB、ブロックC、ブロックDの4つのブロックが抽出されている。データ紐づけ部16は、ブロックAとブロックBの間の時間「13秒」、ブロックBとブロックCの間の時間「20秒」、ブロックCとブロックDの間の時間「67秒」を基に、どのマークとどのブロックが一致するか判断する。この例では、ブロックBに対応するマークが存在しない。そのため、ブロックBを紐づけに使用せず、紐づけ相手の存在するブロックA、C、Dを使用する。
数値制御装置100は、加工プログラムを取得する(ステップS3)。数値制御装置100は、加工プログラムのうち、特徴のある動作を工作機械に指令するブロックを検出する(ステップS4)。
数値制御装置は、ブロックの実行時間とフレームレートを用いて、ステップS9で紐づけられたブロック以外のブロックと映像のフレームを紐づける(ステップS10)。これにより、加工プログラムの全てのブロックが映像のフレームと紐づけられる。
本開示の数値制御装置では、輝度変化や変位ベクトルなどの一般的な画像処理の手法を用いるため構成が簡単である。手動で特徴のある映像にマーキングする場合には、人間が映像の判定を行うので、さらに簡単な構成で、映像とプログラムの紐づけが実現できる。
図15を参照して、数値制御装置100のハードウェア構成を説明する。数値制御装置100が備えるCPU111は、数値制御装置100を全体的に制御するプロセッサである。CPU111は、バスを介してROM112に加工されたシステム・プログラムを読み出し、該システム・プログラムに従って数値制御装置100の全体を制御する。RAM113には、一時的な計算データや表示データ、入力部71を介してユーザが入力した各種データ等が一時的に格納される。
PLC42は、外部機器を制御する。外部機器には、工具交換機、クーラントなどがある。
