  Next, the configuration of the periphery monitoring unit 140 realized in the ECU 14 will be described. As shown in FIG. 4, the periphery monitoring unit 140 includes a data acquisition unit 141, a bird's eye view image generation unit 142, an image processing unit 143, and a display processing unit 144.

  The data acquisition unit 141 acquires various types of information such as captured image data output from the imaging unit 15 and signals generated by operation inputs from the operation input unit 10 and the operation unit 14g.

  The bird's-eye view image generation unit 142 generates bird's-eye view image data representing the periphery of the vehicle 1 from the overhead view point around the vehicle 1 based on the captured image data acquired by the data acquisition unit 141. Note that any method may be used as the method for generating the bird's-eye view image data from the captured image data, and for example, conversion may be performed using a mapping table. The bird's-eye view image generation unit 142 of the present embodiment generates bird's-eye view image data every time captured image data is acquired. Thereby, bird's-eye view image data representing the current situation can be displayed.

  The image processing unit 143 generates an image to be displayed on the display device 8 or the display device 12.

  FIG. 5 is a diagram illustrating image data generated by the image processing unit 143 of the present embodiment for display on the display device 8 or the display device 12. As shown in FIG. 5, the image data 500 is generated by combining a first display area 501, a second display area 502, and a third display area 503.

  The first display area 501 is a display area for displaying the bird's-eye view image data representing the periphery of the vehicle 1 from the bird's-eye view generated by the bird's-eye view image generation unit 142. The bird's-eye view image data of the present embodiment will be described with respect to an example in which the bird's-eye view viewpoint is arranged at a position away from the center of the vehicle 1 by a predetermined distance in the direction perpendicular to the ground. Note that the overhead view viewpoint is not limited to the position arranged in the present embodiment, but is arranged at an appropriate position according to the embodiment.

  The second display area 502 is a display area for displaying a field of view in a predetermined direction from the vehicle 1 based on the captured image data. The predetermined direction is a direction selected according to the operation by the driver or the situation of the vehicle 1, and is a direction determined according to the embodiment. For example, when the vehicle 1 moves backward, the predetermined direction is the backward direction. Compared to the bird's eye view image data of the first display area 501, the second display area 502 displays the environment far from the vehicle 1. Thereby, the driver can confirm whether the vehicle may be advanced in the direction.

  The third display area 503 shows the range of view in a predetermined direction from the vehicle 1 shown in the second display area 502 in the reduced image of the bird's eye view image included in the first display area 501. A display area for displaying the image 511 in a superimposed manner is used. The reduction ratio for converting the bird's eye view image into a reduced image is determined according to the ratio between the first display area 501 and the third display area 503.

  Further, the image 511 showing the field of view in the predetermined direction may be an image showing the field of view in the predetermined direction. For example, the image showing the outline of the range or the range being translucent It may be an image that allows the ground to be visually recognized.

  The image processing unit 143 according to the present embodiment assigns the bird's eye view image data generated by the bird's eye view image generation unit 142 to the first display area 501, and takes captured image data in which a field of view in a predetermined direction based on the captured image data is represented. The image data assigned to the second display area 502 and assigned to the third display area 503 is generated by superimposing the image 511 showing the field of view in a predetermined direction on the reduced image data of the bird's eye view image data. .

  The display processing unit 144 performs processing for displaying the image data generated by the image processing unit 143 on the display device 8 or the display device 12. The output destination of the image data generated by the image processing unit 143 may be a display device that can be referred to by the driver, and can be displayed on the display device 8 or the display device 12 in accordance with the operation of the driver.

  By the way, an image showing the range of the field of view displayed in the second display area 502 can be superimposed on the bird's eye view image data assigned to the first display area 501. However, when an image showing the field of view is superimposed on the bird's eye view image data assigned to the first display area 501, a part of the bird's eye view image data is blocked by the image showing the field of view. . For this reason, it may be difficult for the driver to grasp the state of the ground in the partial area.

  Therefore, in the present embodiment, an image showing the field of view assigned to the second display area 502 is superimposed on the reduced image data (reduced bird's eye view image data) representing the ground. Accordingly, the driver can recognize the surrounding situation without being interrupted by the image or the like by referring to the bird's-eye view image data assigned to the first display area 501, and refer to the third display area 503. As a result, the driver can intuitively recognize the range of the second display area 502.

  Further, the third display area 503 is a reduced image of the bird's eye view image data displayed in the first display area 501, and therefore the situation around the vehicle is represented. Then, by superimposing an image 511 indicating the range of the field of view displayed in the second display area 502 on the reduced image showing the surroundings, the driver can determine the range of the fields of view and the surroundings. Can understand the correspondence.

  In other words, in the present embodiment, the image showing the range of the field of view displayed in the second display area 502 is prevented from being superimposed on the first display area 501, and the reduced image data is Since the image showing the field of view is superimposed, recognition of the situation of the ground around the vehicle 1 from the bird's eye view image data and recognition of the relative positional relationship between the field of view and the ground around the vehicle 1 Can be realized.

(Second Embodiment)
In the first embodiment, the example in which the bird's-eye view viewpoint of the bird's-eye view image data is arranged at a position away from the center of the vehicle 1 by a predetermined distance in the direction perpendicular to the ground has been described. However, the method is not limited to the method of arranging the overhead view viewpoint at the position. Therefore, in the second embodiment, a case where the position of the overhead viewpoint can be changed will be described.

  A configuration of the periphery monitoring unit 600 realized in the ECU 14 according to the second embodiment will be described. As shown in FIG. 6, the periphery monitoring unit 600 includes a data acquisition unit 141, a bird's eye view image generation unit 142, an image processing unit 143, a display processing unit 144, and an operation reception unit 601. Note that the same components as those in the first embodiment are assigned the same reference numerals, and descriptions thereof are omitted.

  The operation accepting unit 601 accepts an operation for changing the overhead view performed by the driver based on signals from the operation inputs of the operation input unit 10 and the operation unit 14g via the data acquisition unit 141.

  FIG. 7 is a diagram illustrating the concept of the overhead view viewpoint changing operation. In the example illustrated in FIG. 7, it is assumed that the overhead viewpoint 701 is changed to the overhead viewpoint 702 based on the operation received by the operation reception unit 601.

  Then, the bird's eye view image generation unit 142 generates bird's eye view image data from the bird's eye view point 702 changed based on the operation.

  FIG. 8 is a diagram illustrating image data generated by the image processing unit 143 of this embodiment for display on the display device 8 or the display device 12. As shown in FIG. 8, the image data 500 is generated by a combination of a first display area 801, a second display area 802, and a third display area 803. Bird's eye view image data based on the overhead view viewpoint 702 is assigned to the first display area 801.

  The image processing unit 143 assigns the bird's eye view image data generated by the bird's eye view image generation unit 142 to the first display area 801, and reduces the image 852 that represents the range of the field of view represented in the second display area 802. Image data is assigned to the third display area 803. The bird's eye view image data and the reduced image data are based on the changed bird's eye view. Similarly to the first embodiment, the second display area 802 is assigned captured image data representing the range of the field of view in a predetermined direction.

  In the present embodiment, a storage unit (for example, SSD 14f) in the ECU 14 stores the three-dimensional shape model data of the vehicle. Then, the image processing unit 143 superimposes the image of the three-dimensional shape model of the vehicle stored in the storage unit when the three-dimensional shape model data of the vehicle is referred to from the bird's-eye viewpoint 702 on the bird's-eye view image data.

  Thereby, the vehicle 850 when viewed from the overhead viewpoint 702 is displayed in the first display area 801. Similarly, the vehicle 851 when viewed from the overhead view point 702 is displayed in the third display area 803.

  Accordingly, the display processing unit 144 is a bird's-eye view showing the periphery of the vehicle 1 in the first display area 801 in the first display region 801 every time the overhead view viewpoint is changed according to the operation received by the operation reception unit 601. An image is displayed, and in the third display area 803, a reduced image of the bird's eye view image with the changed overhead view viewpoint is displayed, and an image 852 showing the range of view in the predetermined direction shown in the second display area 802 is displayed. Superimposed display.

  Further, every time the overhead view viewpoint is changed, the display processing unit 144 displays, in the first display area 801, the vehicle 1 that can be referred to from the overhead view viewpoint together with an image that represents the periphery of the vehicle 1 from the changed overhead view viewpoint. The shape is superimposed and displayed. Similarly, in the third display area 803, the shape of the vehicle 1 that can be referred to from the bird's-eye view is superimposed on the reduced image of the bird's-eye view image from the changed bird's-eye view. Thus, in this embodiment, the vehicle 1 based on the changed overhead view viewpoint is displayed.

  Conventionally, when displaying captured image data, an icon display indicating the relative positional relationship between the imaging range and the vehicle has been used. However, in the icon display, it is difficult to grasp the situation of the ground around the vehicle. Therefore, in this embodiment, a reduced image is used.

  By the way, if the overhead view can be changed after the vehicle icon is superimposed on the reduced image, it is necessary to prepare a vehicle icon for each changed overhead view.

  On the other hand, in the present embodiment, the three-dimensional shape model data of the vehicle 1 is stored, and the three-dimensional shape model data of the vehicle 1 is displayed according to the overhead viewpoint. Thereby, while being able to display the reduced image according to the change of an overhead view viewpoint, the shape of the vehicle according to the overhead view viewpoint can be displayed. As a result, the driver can easily grasp the surrounding situation.

  In the above-described embodiment, the bird's-eye view image showing the periphery of the vehicle is displayed in the first display area, and a reduced image obtained by reducing the bird's-eye view image is displayed in the third display area. An image showing the field of view displayed in the second display area is superimposed on the reduced image of the area. As a result, the situation around the vehicle can be displayed based on the bird's eye view image data, and the correspondence between the field of view displayed in the second display area and the situation around the vehicle can be grasped. it can.
