Description

  The present invention relates to a diagnosis support apparatus and a diagnosis support method.

  Recently, people with developmental disabilities are said to be on the rise. Developmental disorders are known to be detected early and start treatment to reduce symptoms and increase the effect of adapting to society. In Japan, we are aiming for early detection through interviews at the age of 1 and a half. However, there are problems such as shortage of psychiatrists and time-consuming interviews, and the effect is not sufficient. Therefore, there is a need for an objective and efficient diagnosis support device for developmental disorders.

  For early detection of developmental disorders, it is ideal to be able to diagnose at the age of 1 and a half. One of the characteristics of children with developmental disabilities is that they are not good at grasping the whole picture by integrating less local information in slit view. In addition, a method for supporting diagnosis of developmental disorders by applying a method of detecting a gazing point by photographing a human face with a camera and calculating a corneal reflection and a pupil position has been proposed.

  Hereinafter, embodiments of a diagnosis support apparatus and a diagnosis support method according to the present invention will be described in detail with reference to the drawings. In addition, this invention is not limited by this embodiment.

  In conventional slit viewing, for example, an image of a moving observation target is displayed on a display unit behind the slit, and the subject is asked what the observation target is. The diagnosis support apparatus according to the present embodiment displays the back of the slit so that the observation target moves, and then branches the movement direction into a plurality of directions, and further moves the image of the observation target to a display area existing in one direction. To display. Further, an image different from the observation target is displayed in the display area existing in the other direction. Then, the degree of developmental disorder is determined by determining which of the display area in which the subject displayed the image to be observed and the display area in which the image different from the observation target was displayed. If it is a healthy subject, it is considered that a display area displaying an image to be observed is found early and the display area is watched. Therefore, for example, if there is a tendency to gaze at a display area displaying an image to be observed, it can be determined that the image is healthy. With such a configuration, developmental support for diagnosis of developmental disabilities can be performed even for subjects who are about one and a half years old who cannot speak language.

  FIG. 1 is a diagram illustrating an example of an arrangement of a display unit, a stereo camera, and a light source used in the present embodiment. As shown in FIG. 1, in this embodiment, a set of stereo cameras 102 is arranged below the display screen 101. The stereo camera 102 is an imaging unit that can perform stereo shooting with infrared rays, and includes a right camera 202 and a left camera 204.

  Infrared LED (Light Emitting Diode) light sources 203 and 205 are arranged in the circumferential direction immediately before the lenses of the right camera 202 and the left camera 204, respectively. The infrared LED light sources 203 and 205 include an inner peripheral LED and an outer peripheral LED having different wavelengths for emitting light. The pupils of the subject are detected by the infrared LED light sources 203 and 205. As a pupil detection method, for example, the method described in Patent Document 2 can be applied.

  When detecting the line of sight (viewpoint), the position is specified by expressing the space with coordinates. In this embodiment, the center position of the display screen 101 is the origin, the top and bottom are the Y coordinate (up is +), the side is the X coordinate (right is +), and the depth is the Z coordinate (front is +). .

  FIG. 2 is a diagram illustrating an outline of functions of the diagnosis support apparatus 100. FIG. 2 shows a part of the configuration shown in FIG. 1 and a configuration used for driving the configuration. As shown in FIG. 2, the diagnosis support apparatus 100 includes a right camera 202, a left camera 204, infrared LED light sources 203 and 205, a speaker 105, a drive / IF unit 208, a control unit 300, and a display unit. 210. In FIG. 2, the display screen 101 shows the positional relationship between the right camera 202 and the left camera 204 in an easy-to-understand manner, but the display screen 101 is a screen displayed on the display unit 210.

  The speaker 105 outputs a sound or the like for prompting the subject to pay attention during calibration.

  The drive / IF unit 208 drives each unit included in the stereo camera 102. The drive / IF unit 208 serves as an interface between each unit included in the stereo camera 102 and the control unit 300.

  The display unit 210 displays various information such as a target image for diagnosis.

  FIG. 3 is a block diagram illustrating an example of detailed functions of the respective units illustrated in FIG. As shown in FIG. 3, a display unit 210 and a drive / IF unit 208 are connected to the control unit 300. The drive / IF unit 208 includes camera IFs 314 and 315, an LED drive control unit 316, and a speaker drive unit 322.

  A right camera 202 and a left camera 204 are connected to the drive / IF unit 208 via camera IFs 314 and 315, respectively. The driving / IF unit 208 drives these cameras to image the subject.

  A frame synchronization signal is output from the right camera 202. The frame synchronization signal is input to the left camera 204 and the LED drive control unit 316. This causes the left and right wavelength 1 infrared light sources (wavelength 1-LED 303, wavelength 1-LED 305) to emit light at different timings in the first frame, and correspondingly by the left and right cameras (right camera 202, left camera 204). In the second frame, the left and right wavelength 2 infrared light sources (wavelength 2-LED 304, wavelength 2-LED 306) are caused to emit light in the second frame, and the images from the left and right cameras are captured correspondingly.

  The infrared LED light source 203 includes a wavelength 1-LED 303 and a wavelength 2-LED 304. The infrared LED light source 205 includes a wavelength 1-LED 305 and a wavelength 2-LED 306.

  Wavelength 1-LEDs 303 and 305 emit infrared light having wavelength 1. Wavelength 2-LEDs 304 and 306 irradiate wavelength 2 infrared rays.

  The wavelength 1 and the wavelength 2 are, for example, a wavelength of less than 900 nm and a wavelength of 900 nm or more, respectively. When the reflected light reflected by the pupil is irradiated with infrared light having a wavelength of less than 900 nm, a bright pupil image is obtained as compared with the case where reflected light reflected by the pupil is irradiated with infrared light having a wavelength of 900 nm or more. It is because it is obtained.

  The speaker driving unit 322 drives the speaker 105.

  The control unit 300 controls the entire diagnosis support apparatus 100 and outputs the result to the display unit 210, the speaker 105, and the like. The control unit 300 includes a display control unit 351, a viewpoint detection unit 352, and a determination unit 353.

  The display control unit 351 controls display of images on the display unit 210. In the present embodiment, the display control unit 351 displays an image on the display unit 210 so that the slit view is possible. For example, the display control unit 351 displays the image to be observed (first image) in the first display region so as to pass through the slits between the plurality of shielding units, and after the image to be observed passes through the slit, An image to be observed is displayed on one of the second display area and the third display area, and an image (second image) different from the observation target is displayed on the other.

  The first display area is a display area that is partially shielded by a plurality of shielding portions and defined behind the slit. The second display area and the third display area are display areas that are not shielded by the plurality of shielding portions. In addition, the second display area and the third display area are display areas that are determined in two directions that are branched from the moving direction of the observation object that moves behind the slit.

  The shielding unit may be realized as an image displayed on the display unit 210, or may be realized as a physical object provided in front of the display unit 210. In the former case, for example, the display control unit 351 may be configured to always display an image corresponding to the shielding unit in the region to be the shielding unit.

  The viewpoint detection unit 352 detects the viewpoint of the subject in the display area (first display area, second display area, third display area, etc.) of the display screen 101. For example, the viewpoint detection unit 352 detects a viewpoint that is a point that the subject gazes out of the target images displayed on the display screen 101. As a viewpoint detection method by the viewpoint detection unit 352, any conventionally used method can be applied. Below, similarly to patent document 3, the case where a test subject's viewpoint is detected using a stereo camera is demonstrated to an example.

  In this case, first, the viewpoint detection unit 352 detects the visual line direction of the subject from the image captured by the stereo camera 102. The viewpoint detection unit 352 detects the gaze direction of the subject using, for example, the methods described in Patent Documents 1 and 2. Specifically, the viewpoint detection unit 352 obtains a difference between an image captured by irradiating infrared light having a wavelength 1 and an image captured by irradiating infrared light having a wavelength 2, and an image in which a pupil image is clarified. Generate. The viewpoint detection unit 352 uses the two images generated as described above from the images captured by the left and right cameras (the right camera 202 and the left camera 204), and uses the stereo vision technique to determine the position of the subject's pupil ( Eye position) is calculated. In addition, the viewpoint detection unit 352 calculates the position of the subject's corneal reflection using images captured by the left and right cameras. Then, the viewpoint detection unit 352 calculates a gaze vector representing the gaze direction of the subject from the position of the pupil of the subject and the corneal reflection position.

  The viewpoint detection unit 352 detects, for example, the intersection of the line-of-sight vector represented in the coordinate system as shown in FIG. 1 and the XY plane as the viewpoint of the subject. When the gaze direction of both eyes is obtained, the viewpoint may be measured by obtaining the intersection of the left and right gazes of the subject.

  Note that the method for detecting the viewpoint of the subject is not limited to this. For example, you may detect a test subject's viewpoint by analyzing the image image | photographed using visible light instead of infrared rays.

  FIG. 4 is a diagram illustrating an example of eye detection when two cameras (the right camera 202 and the left camera 204) are used. For the two cameras, a camera calibration theory based on a stereo calibration method is applied in advance to obtain camera parameters. As the stereo calibration method, any conventionally used method such as a method using Tsai's camera calibration theory can be applied. Using the eye position detected from the image captured by the right camera 202, the eye position detected from the image captured by the left camera 204, and the camera parameters, the three-dimensional coordinates of the eye in the world coordinate system are obtained. It is done. Thereby, pupil coordinates can be estimated. The pupil coordinate is a coordinate value representing the position of the subject's eye (pupil) on the XY plane. The pupil coordinates can be, for example, coordinate values obtained by projecting the eye position expressed in the world coordinate system onto the XY plane. Usually, the pupil coordinates of the left and right eyes are obtained.

  Returning to FIG. 3, the determination unit 353 determines the degree of developmental disorder of the subject based on the detection result of the viewpoint. For example, the determination unit 353 measures the time (stop time) in which the viewpoint detected by the viewpoint detection unit 352 is detected in the second display region and the third display region, and uses the measured stop time to determine the developmental disorder. Determine the degree. In addition, the determination unit 353 may determine the degree of developmental disorder using the time (movement time) required to move from the first display area to the second display area or the third display area. The determination unit 353 may determine the degree of developmental disorder using both the stop time and the travel time. Below, the example which determines the grade of a developmental disorder using both stop time and movement time is demonstrated.

  The progress of the video (image) displayed on the display unit 210 by the display control unit 351 will be described with reference to FIGS. FIG. 5 is a diagram illustrating a display example of a measurement start state. It is assumed that the individual calibration has been completed before this. Note that the calibration includes not only the above-described camera calibration but also a calibration for eye-gaze detection (eye-gaze detection calibration) for absorbing individual characteristic differences among the eyes of the subject. In the gaze detection calibration, for example, the subject is gazes at a predetermined position (for example, a calibration LED not shown) on a predetermined coordinate system, and the center of the pupil (pupil position) and the corneal reflection position at that time Measure. Then, the calculation parameter for eye gaze detection is corrected so that the eye gaze direction obtained from the measured pupil position and cornea reflection position is directed to a predetermined position.

  A slit 503 is provided between the plurality of shielding portions 501 and 502. One of the shielding portions 502 (left side in FIG. 5) is an image exit side, which is wider than the entrance side (slit 503 side).

  The area near the slit 503 is the first display area (hereinafter referred to as area A1), the area near the upper image exit is referred to as the second display area (hereinafter referred to as area A2), and the area near the lower image exit is the first display area. 3 display areas (hereinafter referred to as area A3).

  FIG. 6 is a diagram illustrating a display example in a state where the image starts to move. FIG. 6 shows an example of displaying a dog-shaped image. When the display control unit 351 displays the image so as to move behind the slit 503, the subject can observe the dog image from the slit 503.

  FIG. 7 is a diagram illustrating a display example in a state where the image is further moved. By moving the image, the subject can estimate the entire image. In the case of an image with few features, subjects with a developmental disorder are not good at predicting the whole picture.

  FIG. 8 is a diagram illustrating a display example in a state where the image is further moved. The display control unit 351 displays an image so as to follow a route branched in the middle. In addition, the display control unit 351 displays an image of a dog that is a correct answer that has passed through the slit 503 (hereinafter referred to as a correct image (the upper image in FIG. 8)) and an image of a bear face that is an incorrect answer (which is different from the above). Hereinafter, the display of each image is controlled so that an incorrect image (the lower image in FIG. 8) appears gradually from the exit. A healthy subject finds the correct image early and sees the correct image. The determination unit 353 digitizes this situation and uses it for determination. For example, the determination unit 353 measures the moving time of the gazing point from the area A1 to the area A2 and the moving time of the gazing point from the area A1 to the area A3.

  FIG. 9 is a diagram illustrating a display example in a state where the image is further moved. The image of the dog appears at the upper exit, and the image of the bear's face appears completely at the lower exit. The display control unit 351 stops the image for a predetermined time in this state. The determination unit 353 measures the stop time of the gazing point in the area A2 and the area A3.

  In the present embodiment, the same measurement is performed twice. In the second measurement, the display control unit 351 displays the correct image at the lower exit and displays the incorrect image at the upper exit.

  FIG. 10 is a diagram illustrating a display example in a state where an image starts to be displayed near the exit during the second measurement. FIG. 11 is a diagram illustrating a display example in a state in which the image is completely displayed from the exit during the second measurement. The movement time and the stop time are measured in the same manner as described with reference to FIGS.

  FIG. 12 is a flowchart illustrating an example of measurement and diagnosis processing. First, the display control unit 351 sets the position (coordinate range) of each area on the screen (step S601). For example, the display control unit 351 sets the coordinate ranges of predetermined areas A1, A2, and A3.

  Next, the display control unit 351 sets 1 to the variable n (step S602). Next, the display control unit 351 determines the image 1 and the image 2 to be displayed (step S603). In a normal test, a plurality of images are prepared, and an image to be displayed at random is determined. In the example of FIG. 12, image 1 is a correct image and image 2 is an incorrect image.

  Next, the display control unit 351 displays the image 1 so as to be completely hidden by the shielding unit 501 at a position immediately before the slit 503 (step S604). In this state, the image 1 is hidden by the shielding portion 501 and cannot be seen from the slit 503.

  Next, the determination unit 353 starts measuring the viewpoint stop time t0 in the area A1 (step S605). Immediately thereafter, the display control unit 351 starts moving display of the image 1 (step S606). Thereby, a part of the image 1 can be seen from the slit 503.

  Next, the display control unit 351 determines whether the image 1 has completed passing through the slit 503 (step S607). If not completed (step S607: No), the process returns to step S606. When completed (step S607: Yes), the determination unit 353 completes the measurement of the viewpoint stop time t0 in the area A1 (step S608).

  Next, the determination unit 353 compares the viewpoint stop time t0 in the area A1 with a predetermined threshold value T0 (step S609). When the viewpoint stop time t0 in the area A1 is less than the predetermined threshold value T0 (step S609: Yes), the process returns to step S604 and is repeated. In this case, it is because the subject has not observed the slit 503 so much, and accurate determination cannot be made.

  When the viewpoint stop time t0 in the area A1 is equal to or longer than the predetermined threshold T0 (step S609: No), the determination unit 353 determines whether or not the variable n = 1 (step S610). When n = 1, it is the first measurement, and when n = 2, it is the second measurement. Since n = 1 at first (step S610: Yes), the process proceeds to step S611. The display control unit 351 prepares so that the image 1 is moved to the upper exit and displayed, and the image 2 is moved to the lower exit and displayed. That is, the display control unit 351 displays the image 1 immediately before the upper exit and displays the image 2 immediately before the lower exit (step S611). In this state, since the subject is hidden by the shielding unit 502, the subject cannot see the image.

  Next, the determination unit 353 starts measuring the viewpoint stop times t11 and t21 in the areas A2 and A3 (step S612). The determination unit 353 starts measuring the viewpoint entry times t12 and t22 in the areas A2 and A3 almost simultaneously (step S613). The entry time refers to the time (movement time) until the point of sight moves from area A1 to area A2 or area A3, and is used to determine how quickly a correct image is found.

  Next, the display control unit 351 starts moving display from the exits of the images 1 and 2 (step S614). The test subject can view an image that makes it possible to guess the situation that the image is directed to the exit after passing through the slit 503 and then emerges from the exit. The display control unit 351 determines whether the image 1 and the image 2 have completed passing through the exits (step S615). If not completed (step S615: No), the process returns to step S614 and the process is repeated. When completed (step S615: Yes), the process proceeds to step S616.

  Next, the determination unit 353 completes the measurement of the viewpoint stop times t11 and t21 in the areas A2 and A3 (step S616). Further, the determination unit 353 completes the measurement of the area A2 and area A3 viewpoint entry times t12 and t22 (step S617).

  Next, the determination unit 353 determines whether or not the variable n = 1 (step S625). When n = 1 (step S625: Yes), the determination unit 353 updates to n = 2 (step S627), returns to step S604, and repeats the process. When n is not 1 (step S625: No), the determination unit 353 performs calculation for diagnosis support (step S626). Details of the diagnosis support calculation process in step S626 will be described later.

  If n = 1 is not satisfied in step S610 (step S610: No), the process proceeds to step S618. First, the display control unit 351 displays the image 1 immediately before the lower exit and displays the image 2 immediately before the upper exit (step S618).

  Next, the determination unit 353 starts measuring the viewpoint stop times t13 and t23 in the areas A2 and A3 (step S619). In addition, the determination unit 353 starts measuring the viewpoint entry times t14 and t24 in the areas A2 and A3 almost simultaneously (Step S620).

  Next, the display control unit 351 starts moving display from the exits of the image 1 and the image 2 (step S621). The display control unit 351 determines whether the image 1 and the image 2 are completely passed through the exits (step S622). If not completed (step S622: No), the process returns to step S621 to repeat the process. When completed (step S622: Yes), the process proceeds to step S623.

  Next, the determination unit 353 completes the measurement of the viewpoint stop times t13 and t23 in the areas A2 and A3 (Step S623). Further, the determination unit 353 completes the measurement of the area A2 and area A3 viewpoint entry times t14 and t24 (step S624). After step S624, the process proceeds to step S625.

  FIG. 13 is a flowchart showing an example of the diagnosis support calculation process shown in step S626 of FIG. First, the determination unit 353 calculates the stop time B of the correct image area (step S701). The stop time B is calculated by B = t11 + t23. Next, the determination unit 353 calculates the stop time C of the incorrect image area (step S702). The stop time C is calculated by C = t21 + t13.

  The correct image area represents an area where the correct image is moved and displayed. In the above example, the area A2 is the correct image area during the first measurement, and the area A3 is the correct image area during the second measurement. The incorrect image area represents an area where the incorrect image is moved and displayed. In the above example, the area A3 is the correct image area during the first measurement, and the area A2 is the incorrect image area during the second measurement.

  Next, the determination unit 353 calculates the entry time D of the correct image area (step S703). The entry time D is calculated by D = t12 + t24. Next, the determination unit 353 calculates the entry time E for the incorrect image area (step S704). The entry time E is calculated by E = t22 + t14.

Next, the determination unit 353 calculates an evaluation value A used for determination by the following evaluation formula (step S705). k is a predetermined coefficient for weighting the stop time and the entry time. The coefficient k may be arbitrarily designated.
A = B-C + k (ED)

  Next, the determination unit 353 determines whether or not the evaluation value A is smaller than the threshold value K (step S706). When A is smaller than K (step S706: Yes), the determination unit 353 determines that the possibility of developmental disorder is high (step S707). When A is K or more (step S706: No), the determination unit 353 determines that the possibility of developmental disorder is low (step S708).

  Note that the evaluation formula is not limited to the above example, and any other evaluation formula may be used as long as it is a formula that uses at least the time during which the degree of developmental disability can be determined among each stop time and each entry time. . For example, only the stop time may be used for the determination, such as A = BC. Further, for example, only the entry time may be used for determination, such as A = ED.

As described above, according to the present embodiment, for example, the following effects can be obtained.
(1) Diagnosis support is possible even for infants who cannot speak the language of one and a half years.
(2) Diagnosis is performed not only with the gazing point stop time but also with the time to follow the moving image, so that highly accurate diagnosis support is possible.
(3) Since the measurement is performed by changing the moving direction, accidental bias can be avoided.

  The embodiment of the present invention can be variously modified without departing from the gist thereof. For example, the width or shape of the slit 503 may be changed depending on the size or shape of an image passing behind the slit 503 or the degree of possibility of developmental disorder of the subject. Further, the moving speed of the image passing behind the slit 503 may be changed similarly.
