An example of means). Reference numeral 19 denotes work content information indicating the measured work content of the worker. 20 is a work content measuring device (worker measuring device) comprising the above 1-19. Reference numeral 21 denotes a work management device (worker management device) using the work content measuring device 20.

  In FIG. 1, for example, it is assumed that a work target 12 is an office IT device (hereinafter also referred to as a device 12), and a worker 11 is a worker in an assembly factory of the device 12. The device 12 is mounted on the carriage 13 and is transported in the factory, and at the same time, a plurality of parts are assembled in the factory by a plurality of workers and a plurality of processes. The factory can measure the worker's work contents for assembly progress management, work reliability confirmation, parts management, etc., improving the production efficiency per hour of the factory, reducing the burden on the worker, It is possible to reduce useless work, thereby reducing the environmental load, and at the same time, improve the reliability of the product and reduce the load on the product user (user). Furthermore, as a result, it contributes to cost reduction, and the burden on the product user can be reduced.

  In FIG. 1, an image within a specific angle within a range indicated by two dotted lines in the drawing can be acquired by the camera 1. By setting the worker 11 and the work target 12 within this range, the image information 2 of the worker 11 and the work target 12 can be acquired as the image information 2. The image processing means 3 performs image processing on the image information 2 so that the shape and position of the left and right hands of the worker 11 and the shape and position of the work object 12 can be measured. Based on this information, the worker information / work object information acquisition means 4 combines evaluation means such as correlation evaluation means based on setting information stored in advance or evaluation means by learning with these time-series data. It is possible to acquire worker information / work object information 5 by using them.

  The specific angle in the range indicated by the two dotted lines in the camera 1 described above is an angle equal to or smaller than the “camera angle of view” determined by the lens focal length of the camera 1, the size of the camera imaging element, and the aperture. Yes, the angle of view may be changed as appropriate by having a zoom lens with a variable focal length. When it is necessary to acquire an image of the entire movement of a person, it is preferable that the entire body of the worker is set to the minimum angle that can be always acquired during the target work. If the angle is too large, the resolution of the image deteriorates, and an error is likely to occur during image processing. Specifically, in the case where a camera is installed near the ceiling with a height of 3 m and the standing work is performed on the equipment, the angle is 30 degrees to 75 degrees (the lens focal length is about 28 to 35 mm film camera equivalent). Equivalent to 85 mm).

  In addition, as the image processing for the image information 2 in the image processing means 3 described above, after the left and right hands of the worker are recognized by the contour extraction processing, contour tracking processing, vector extraction processing, and pattern recognition processing, the worker The shape and position of the left and right hands and the shape and position of the work object can be measured. The image processing method in the image processing means 3 is not limited to the above processing.

  In addition, as the setting information stored in advance as described above, the process of the worker 11 with respect to the work object 12 (element processes such as “attaching part A”, “moving the bogie of equipment”) and operation ( Elemental actions such as “grab part A”, “move part A”, “push part A”, “release part A”, “grab equipment”, “move equipment (by carriage)” And correlation information with the image processing result of the image acquired corresponding to this process and operation. The correlation information can be acquired by using statistical processing such as SVM (support vector machine), Bayesian inference, neural network, or the like. Further, by using this statistical processing, correlation evaluation means, and further evaluation means such as learning evaluation means can be applied.

  When applying this evaluation means, not only the image data at a specific time is simply used for the evaluation of the work at that time, but also change information as time series data of the image data is obtained by a separate prior correlation verification experiment. Accuracy when evaluating information related to work and workers correlating to the image data from the image data by using in combination with information related to the work and workers as time series data stored as the evaluation target candidates Will improve. Specifically, the information to be combined includes time series image data and work correlation information, time series image data and worker correlation information, work and worker correlation information, and work time series information. is there.

  On the other hand, in FIG. 1, a sensor I6 provided with a three-axis linear acceleration sensor and a three-axis gyro, which is a wireless signal output type that self-detects spatial information, is attached to the work object 12, which is wirelessly connected. Output a signal. The signal from the sensor I6 is input to the wireless signal input means 7 that is spatially disconnected from the work object 12. Thereafter, the signal is processed by the signal information processing means I8 to become sensor signal processing information I9. The integrated information processing means I10 performs integrated information processing on the sensor signal processing information I9 and the worker information / work object information 5. The integrated information processing here is a process of outputting information by integrating plural elements of information (output of first integrated information). In addition, the work contents at this time include a very plurality of work such as a work of rotating the work object 12 by 90 degrees, a work of inserting and installing parts, and a work of screwing parts.

  The sensor I6 provided with the three-axis linear acceleration sensor and the three-axis gyro can detect the relative space information in which the sensor exists from the signal of the sensor. When the acceleration of the three-axis linear acceleration sensor is large, the acceleration of movement to the part with the sensor such as the hand or arm in the large direction is large, and in the case of the sensor provided with the axis gyro, the rotational acceleration is large. Is the case. Further, the triaxial linear acceleration sensor can calculate the relative movement distance by executing the speed, the double integration process and the correction process by executing the integration process and the correction process for the acceleration. In the integration process, it is essential to specify zero speed. However, in a normal work process, the moment of gripping a part is near zero speed, and the moment of gripping a specific part is determined by the three-axis linear acceleration sensor and 3 By detecting from the information of the sensor I provided with the axis gyro, a state close to zero speed can be detected, and thereby the moving speed and the relative moving distance can be calculated.

  In the integration process, worker information and work object information 5 obtained separately from image data and sensor signal processing information I9 are handled as one multidimensional data, and new multivariate analysis is performed on the one multidimensional data. This is to obtain work content information 19 related to worker information / work object information. As specific information processing means, statistical processing such as the aforementioned SVM (support vector machine), Bayesian inference, neural network, or the like can be used.

  In such a situation, the sensor I6 attached to the work object 12 described above may be attached to the carriage 13 on which the work object 12 is installed, which is an object connected to the work object 12. In this case, since a cart that is used a plurality of times in the factory without using the product itself is used, there are advantages such as installation and recovery of the sensor I6 and the need for individual calibration.

  At the same time as the configuration described above, a wireless signal output type that self-detects the spatial position and sensors II14a and 14b provided with a three-axis linear acceleration sensor and a three-axis gyro are attached to the left and right arms of the worker industry pair 11. These output signals wirelessly. The signal of the sensor II 14 is input to the wireless signal input means 15 that is spatially disconnected from the worker. Thereafter, the signal is processed by the signal information processing means II16 to become sensor signal processing information II17. The integrated information processing means II18 performs integrated information processing on the sensor signal processing information II17 and the first integrated information (the worker information / work object information 5 and the sensor signal processing information I9 are integrated). Do. Here, the integrated information processing is a process of integrating information of a plurality of elements and performing a unified output (second integrated information, that is, output of work content information). By this integrated information processing II17, work content information 19 is output as a measurement result of the work content.

  The work management device 21, which is separate from or integrated with the work content measurement device 20, uses the work content information 19 indicating the work content measured by the work content measurement device 20 to manage the following work. The work management device 21 integrates, for example, the assembly progress status, work status, and component usage status of the worker 11 with information acquired from the production plan and process of the factory in advance or in real time separately from the work content measurement device 20. Therefore, whether the worker 11 is assembled as planned, the worker 11 is busy and the load is not high, no trouble has occurred, there is no possibility of physical danger, or the work procedure is incorrect It is possible to manage whether there are any missing parts or missing parts.

  Conventionally, only from the worker information / work object information 5 based on the image information 2 requires a plurality of cameras 1 to acquire the image information 2 and the load on the CPU (Central Processing Unit) is very high. There was a problem that it was only possible to measure the work content, such as being expensive, difficult to perform real-time processing, and having a large delay. As a technique for improving the problem, the sensor signal processing information I9 based on the sensor I6 is integrated (added) into the worker information / work object information 5 to obtain the time when the work object 12 actually moves and Utilizing the fact that the position change and impact can be measured, the number of cameras 1 is reduced, the CPU load is reduced, the cost is reduced, and real-time processing is realized.

  However, only by adding sensor signal processing information I9 based on sensor I6, only the positional change and impact of actual work object 12 are measured, and the movement of worker 11 who performs the work is directly measured by sensor I6. Because it is not, it is not enough to measure the work content, which may make the image processing more complicated, or conversely, the granularity of work content measurement is reduced or the reliability is reduced. .

  Therefore, in the first embodiment of the present invention, the output information (first integrated information) from the integrated information processing means I10 in which the conventional sensor signal processing information I9 and the worker information / work object information 5 are integrated. In addition, sensor signal processing information II17 based on the signals of sensors II14a and 14b that directly measure the movement of the worker 11 who is actually working is added and integrated. Therefore, it is possible to reduce the granularity or improve the reliability of the work content defined by the operation standard of the worker 11.

  FIG. 2 shows a signal acquired by the sensor II 14b attached to the left arm of the worker 11 in the work content measuring apparatus 20 according to the first embodiment of the present invention. In FIG. 2, the horizontal axis represents relative time (unit: seconds), and the vertical axis represents acceleration (unit: mG). Also, x, y, and z, respectively, when the left arm is moved forward with the back of the hand horizontal, front and rear are x (positive is the front side), left and right are y (positive is the right hand side), and upper and lower are z ( Positive is the floor side). FIG. 2 shows an assembly work including an operation in which the worker 11 rotates the copying machine 45 degrees for each carriage 13 when one work object 12 (for example, a copying machine) is installed in each carriage 13. In this case, the measured signal is shown. Separately, the sensor I6 is set on the carriage 13. A small wireless hybrid sensor WAA-00 (manufactured by Wireless Technology Co., Ltd.) composed of a triaxial linear acceleration sensor was used for the sensor I6 and the sensor II14b (mounted on the left hand). Actually, a plurality of acceleration sensors are attached to the worker 11.

  For example, between about 0.7 seconds and about 1.5 seconds in FIG. 2 (indicated by the double arrows in the figure), the worker 11 rotates the carriage 45 degrees using the left hand and the left hand is The signal of a situation where a part of the copier 12 is being gripped or touched is shown, and the operator 11 points the back of his left hand and the back of his hand to the left to grab a bare frame during the assembly of the copier 12. For this reason, an acceleration of about 1000 mG is applied on average, and conversely, an acceleration of about 0 level is applied on the Z axis on the contrary. Further, these work contents and times were measured by image information using a camera that can acquire movements of the left and right hands separately provided from the sensor I6 and the sensor II14b.

  At this time, immediately after the operator 11 grasps the bare frame of the copying machine 12 with his left hand, the x, y, and z axes show steep peaks, and this applies force to impart kinetic energy to the copying machine 12. Corresponds to the power added to the hand to add. Immediately after the operator 11 releases the bare frame of the copying machine 12 with his left hand, the x, y and z axes show a large change in the amount, which is applied to the frame of the copying machine 12 by applying force. The left hand that was moving is released smoothly, and at the same time, the hand is moved quickly to prepare for the next step.

  However, the time when the worker 11 measured based on the signal other than the signal of the sensor II 14b shown in FIG. 2 as a vertical solid line at about 1.5 seconds and the bare frame of the copying machine 12 is released with the left hand, and the sensor II 14b at that time. As can be seen from the relatively smooth displacement state signal, when the worker 11 performs a smooth operation for improving the productivity efficiency, it adheres to the worker 11 depending on the required time resolution. The sensor II 14b alone does not always provide highly reliable work content measurement. However, it is possible to detect the time at which the left hand of the worker 11 is in contact with the naked frame based on the image information 2 of the camera 1, and processing this information by the integrated information processing means II 18 makes it more reliable. This makes it possible to realize highly reliable work content measurement. Similarly, by processing these pieces of information with the integrated information processing means II18 for the signal of the sensor I6 attached to the work object 12 depending on the work content, more reliable work content measurement can be realized. Become.

  As shown in FIG. 2, the sensor signal processing information II17 based on the signal of the sensor II14b attached to the worker 11 is used as the worker information / working object information 5 based on the image information 2 by the conventional camera, and the working object. In addition to the sensor signal processing information I7 based on the sensor I6 attached to 12, the integrated information processing reduces the granularity of the work content defined by the operation standard of the worker 11 or increases the reliability. It will be possible to improve. Further, even when the image information of the left and right hand movements by the camera is at the blind spot in the work object 12 and cannot be obtained, it is possible to improve the reliability of the work content measurement together with the information of the sensor I6. become able to.

  FIG. 2 shows only the signal of sensor II 14b, but in the same way, signals attached to the right arm, left and right upper arms, waist, chest, head, ankle, etc., have signals characteristic of the process. It is effective to appropriately provide various work contents related to the assembly of the copying machine in the factory of the worker 11 or the work object 12, and the information from the plurality of sensors is integrated for information processing. It is preferable.

  In FIG. 3, the graph shown on the upper side shows the signal of the sensor II 14b including the work content for 45 degrees rotation of the specific carriage 13 shown in FIG. 2 (same data as FIG. 2), and the graph shown on the lower side is The signal of the sensor II 14b including the work content for 45 degrees rotation of the carriage 13 different from the above is shown. In FIG. 3, the horizontal and vertical axes and the conditions are the same as those in FIG. As shown in FIG. 3, even if the correlation of the signal of the sensor II 14b differs depending on the work content, it is very high for work with a common granularity such as 45 degrees rotation of the copying machine 12 together with the carriage 13. Recognize. Therefore, by performing information processing such as correlation coefficient processing, principal component analysis, or pattern recognition processing, it is possible to specify the work content defined by the operation standard of the worker 11 from the output of the sensor II 14b.

  In the present embodiment, in FIG. 1, the integrated information processing means is divided into two parts, that is, integrated information processing means I10 and integrated information processing means II18, but worker information / work object information 5, sensor signal processing Even in a configuration provided with a new integrated information processing III in which the integrated integrated information processing I and the integrated information processing II are integrated, as integrated information processing for the information I9 and the sensor signal processing information II17. It is equally effective. In this case, if the information processing part of the work content measuring apparatus 20 can be made smaller by integration, the reliability of the measurement content can be improved by simultaneously handling the relevant data instead of the step. . However, the number of data types to be processed increases, and depending on the information processing method, it may increase by a power. In some cases, it may be effective to use step processing. The selection should be made according to the type and number of the sensors I6 and II14.

  In this embodiment, the configuration in which the configuration of the wireless signal input means 7 of the sensor I6 and the wireless signal input means 15 of the sensor II in FIG. Also in this case, it becomes easier to specify the work content defined by the operation standard of the worker 11 as compared with the conventional case. As a specific configuration in this case, the sensor I6 is provided to the worker 11 and self-detects a part of the spatial position of the worker 11, and the sensor II16 includes the work object 12 or the work object. The self-detection is performed on the work object 12 or the spatial position of the object connected to the work object 12.

  2 and 3, linear acceleration sensors are used as the sensors I and II. However, the sensor II is not limited to the linear acceleration sensor, and the sensor II that self-detects the spatial position may be a gyro sensor or a geomagnetic sensor. Even the work content measuring apparatus characterized by the above is similarly effective. However, it is preferable that the sensor is capable of detecting not only the position of the worker but also the body movement.

  In addition, the work that can be applied (measured) in the present embodiment is not limited to the assembly site of a copying machine or the like in a factory. This is also effective when safety is important at the construction site or when assistance from a third party other than the worker holding the work object is required. It is equally effective for education in these fields. Furthermore, in a car driver, a medical site, an office, or the like where the relationship between the work performed by the worker's body and the object is important, the work content measuring apparatus 20 according to the present embodiment and work management using the work content measuring apparatus 20 are provided. The device 21 can realize various effects such as improving the production efficiency, improving the reliability of work, improving the safety of work, reducing the environmental load as a result, and realizing cost reduction.

  As described above, according to the present embodiment, image processing on the image information of the worker and the work object acquired from the camera and the worker using the sensor that self-detects the spatial position provided on the work object. A work content measuring device for measuring work content and a work management device using the work content measuring device that realizes highly accurate work content measurement, and at the same time, a low cost and low environmental load work content measuring device and work management using the same. An apparatus can be realized.

[Second Embodiment] (Embodiment according to Claim 2)
The configuration of the work content measuring apparatus showing the second embodiment of the present invention will be described with reference to FIG.

  FIG. 4 shows a configuration in which first control means (sensor I / II and signal information processing means I / II control means) 22 is provided in the configuration of FIG. 1 according to the first embodiment of the present invention. The first control means 22 is configured to detect the sensor I, the sensor II, the sensor information according to the worker information / work object information 5 (which may be either worker information or work object information) based on the image information 2 from the camera 1. It is means for controlling a plurality or one of signal information processing means I and signal information processing means II simultaneously or individually. If the sensors I and II have wireless outputs, these sensors are provided with wireless command input means, and the first control means 22 is provided with wireless command output means. Sensor I and sensor II can be controlled directly. The signal information processing means I and the signal information processing means II can be controlled by outputting a command signal by wire.

  For example, based on the worker information / work object information 5, the first control unit 22 determines that the worker 11 is 70 cm or more away from the work object 12 and that the position of the work object 12 has little change. In this case, since the position and state of the work target 12 are not displaced by the worker 11, the sensor I6, the wireless signal input means 7 and the signal information processing means I8 attached to the work target 12 are set in the power saving mode. To control. Thereby, the battery operating life of the sensor I6 is improved, the power consumption of the wireless signal input means 7 and the signal information processing means I8 is realized, and further, the communication load related to this is reduced to further reduce the environmental load. The work content measuring apparatus 20 can be realized.

  Further, for example, the first control means 22 makes the worker 11 to the work object 12 when the worker 11 becomes 10 cm or less from the work object 12 based on the worker information / work object information 5. It is determined that there is a high probability that the above work will occur, and control is performed so as to increase the sampling frequency of the sensor I6 attached to the work object 12, or control is performed so as to increase the transmission rate of the wireless signal input means 7, Control is performed so as to improve the processing capability of the signal information processing means I8, and further control is performed so as to change to the optimum processing means learned according to the worker information / work object information 5. As a result, the work content measuring apparatus 20 with higher reliability and reduced environmental load can be realized.

  The first control means 22 according to the present embodiment is not applied only to the distance information described above as the worker information / work object information 5, but distinguishes the worker based on the image information 2 by the camera 1 and the work target. It is possible to appropriately control the sensor I, the sensor II, the signal information processing means I, and the signal information processing means II in accordance with the object distinction, the work content, the time, and the like.

[Third embodiment] (Embodiment according to claim 3)
The configuration of the work content measuring apparatus showing the third embodiment of the present invention will be described with reference to FIG.

  FIG. 5 shows a configuration in which second control means (image processing means control means) 23 is provided in the configuration of FIG. 1 according to the first embodiment of the present invention. The second control means 23 can change the image processing setting by controlling the image processing means 3 for the image information 2 by the camera 1 based on the sensor signal processing information II for the sensor II.

  For example, the second control means 23 is meaningful when the worker 11 can confirm a large operation, that is, a large signal change or a specific work content, based on the sensor signal processing information II for the sensor II. It is determined that there is a high possibility of working, and a control command is output to the image processing means 3. The image processing means 3 that has input this control command performs image processing in an image processing mode different from that before the input of the control command, such as image processing for separating specific work contents or image processing at a high frame rate.
