Description

  The present invention particularly relates to camera display control for driver assistance in a vehicle.

In recent vehicles, a system for photographing a rear side and a rear side that are a blind spot of a driver with a camera and displaying the same on a monitor has started to spread. It has also been proposed to eliminate blind spots caused by in-vehicle devices using this technology for imaging the periphery of a vehicle (see, for example, Patent Document 1).
Furthermore, the driver may not be able to fully recognize the blind spot part due to dirt on the camera lens, etc., but the lens dirt is detected from changes in the luminance information of the pixels that make up the camera image. A method for notifying lens contamination by outputting a message has been proposed (see, for example, Patent Document 2).

FIG. 4 is a flowchart showing the processing procedure of the camera selection processing 110 of the present embodiment. Here, an example of processing when another camera is selected when the rear camera is defective will be described.
S400 is a process for checking the presence or absence of a camera selection operation of the camera operation unit 109. In this process, the state of the camera operation unit 109 is checked at regular intervals.
S401 is processing for acquiring the state of the selected camera from the camera state detection unit 104 when there is an operation based on the result of S400. The priority flag is set to 0.
In step S402, the detection result of the camera state detection unit 104 acquired in step S401 is received, and processing for checking whether the camera is normal based on the presence or absence of a defect in the initially selected camera is performed. The priority flag is set to 1 when the camera is abnormal.
S403 is camera selection unit switching control processing. When the camera is normal in S402, switching control of the camera selection unit 107 is performed so as to select a corresponding camera.
S404 is a process of outputting and displaying the video of the selected camera on the display device.
In S405, when it is determined in S402 that the initial selection camera is defective, the priority flag is set to 1.
S406 is an alternative camera selection process, which refers to a camera selection candidate in the camera selection list 105 and selects a camera corresponding to the priority flag. For example, if the priority flag is 1, a camera whose selection candidate is 1 is selected.
In step S407, the state of the selected alternative camera is acquired from the camera state detection unit 104 based on the result of step S406.
In step S408, the detection result of the camera state detection unit 104 acquired in step S407 is received, and processing for checking the presence / absence of a defect is performed. If the detected result is normal, the processes of S403 and S404 are performed.
In step S409, the priority flag is counted up.
S410 is a process for checking the presence or absence of the next alternative camera when there is a problem in S408. In S410, the next alternative camera selection candidate is referred to in the camera selection list 105 to check whether there is a camera that matches the priority flag. If there is a camera that matches the priority flag, the processing from S406 is repeated again. If no camera matches the priority flag, the process proceeds to the next step S411.
S411 is a process of outputting a message to the driver when there is no camera that matches the priority flag in S410, and the system control unit 106 displays the camera failure occurrence message read from the message holding unit 111 on the display unit 108.

(S406).
Further, the camera state detection unit 104 acquires the result of detecting the state of the left camera 102 (S407). As a result of the acquisition, it is found that the left camera 102 is normal (S408), and the camera selection unit 107 The left camera 102 is selected (S403), and the captured image of the selected left camera 102 is output to the display device 108 (S404).
In the first embodiment, the rear camera 101, the left camera 102, and the right camera 103 may be connected to the camera state detection unit 104 and the camera selection unit 107 not only by an analog line but also by a digital signal line or an in-vehicle LAN. good. In this case, the connection form (topology) is not limited to the star type as shown in FIG. 1, but may be a ring type, a bus type, or a daisy chain type. In the case of a daisy chain connection, a video is transmitted by multiplexing a plurality of videos in one cable, and video selection is performed by selecting a video channel in the camera selection unit 107.
In the first embodiment, a message is output to the driver when there is a defect in the selected camera, and there is a defect in the alternative camera and there is no displayable video. However, the selected camera has a defect. When this is detected, the driver may be notified using a message.
In the first embodiment, the display device is used as the message output to the driver. However, the notification may be made using voice.
Further, in the first embodiment, a camera that holds camera type information that is information regarding the installation direction such as “rear”, “left”, and “right” is used for each camera and is further connected by the camera state detection unit 104. By detecting the presence / absence of the camera and the camera type information, the camera selection processing unit 110 performs control to select the next alternative camera when there is no corresponding camera in the alternative camera list described in the camera selection list 105. You can also.
As described above, according to the first embodiment, when the camera image cannot be sufficiently viewed due to a malfunction of the driving support camera, the driver's visibility is ensured by automatically displaying the substitute image without any user operation.

Note that the camera state detection unit 104 in this embodiment has a function of confirming the installation position of the camera, and the confirmation of the installation position is information stored in advance in the camera, for example, vehicle type, installation position, direction, Use information such as angle of view. If no camera is installed, the process ends.
In step S1002, a camera installation confirmation result is received in step S1001, and the check ID of the camera is set to 1.
In step S1003, camera information having the same ID as the check ID is acquired from the imaging range information.
In step S1004, the camera check ID is set to +1.
In S1005, it is determined whether there is camera information having the same ID as the check ID. If there is camera information, the process returns to S1003, and if not, the process proceeds to S1006.
In step S1006, the processing of steps S1003 to S1005 is performed for each camera, and an alternative camera for each camera is calculated based on the acquisition result of the imaging range information for each camera, and is stored as the camera selection list 105. It should be noted that the calculation can be performed by increasing the priority of the ones with a large overlap of the imaging ranges, that is, by increasing the priority of ones with a small blind area.
In the above-described embodiments, the horizontal angle of view is used as an example of the imaging range, but a vertical angle of view may be used.
In the above-described embodiment, the priority order is determined in the descending order of the horizontal angle of view as an example of the imaging range, but when the overlapping angle of view is the same, the distance from the driver's seat is added as a selection criterion. Also good. In the case of such a driving assistance camera, the blind spot tends to increase as the distance from the driver increases, and it is considered that assistance using a camera image is necessary.
In the above-described embodiment, only the alternative camera is selected, but the captured image may be partially enlarged using the imaging range information of the alternative camera, and an image close to the imaging range of the original camera may be displayed. For example, if the alternative camera is an omnidirectional camera, it is possible to enhance the user's safety without feeling uncomfortable by cutting out the portion corresponding to the imaging range of the original camera and correcting and displaying the distortion.
As described above, according to the above-described embodiment, it is possible to generate an alternative camera for each camera and generate a camera selection list by preliminarily holding imaging range information corresponding to the camera installation position, which is mounted on the vehicle. Even when the number of cameras is increased or decreased, it is not necessary for the user to rewrite the camera selection list, and convenience is improved.
