Problems solved by technology

[0010] However, in such a method, there is a problem that the area of ​​the hood of the vehicle excluded from the monitoring target area cannot be accurately detected.
[0011] For example, in the detection method of the hood area as described above, light is reflected by the hood, and the similarity between the hood area and the template image becomes low, so it is difficult to accurately detect the hood area.
In addition, since the installation position of the camera for the driving recorder is different for each vehicle, the position on the image of the hood area cannot be uniquely determined.

Embodiment 1

[0036] The configuration of the image processing device according to the first embodiment will be described. figure 1 It is a functional block diagram showing the configuration of the image processing device according to the first embodiment. Such as figure 1 As shown, the image processing device 10 has a generation unit 11 , a calculation unit 12 , and a determination unit 13 .

[0037] The generation unit 11 generates an average image of difference images in the video data based on the difference between two adjacent frames in one video data.

[0038] The calculation unit 12 calculates the sum of the horizontal brightness values ​​of the average image for each point in the vertical direction of the average image.

[0039] The specifying unit 13 selects a predetermined number of points from points below the position of the vanishing point in the average image, and the points having a higher value of the sum of luminance values ​​of the second differential value, and selects...

Embodiment 2

[0042] The configuration of the image processing device according to the second embodiment will be described. figure 2 It is a functional block diagram showing the configuration of the image processing device according to the second embodiment. Such as figure 2 As shown, the image processing device 100 has a communication unit 110 , an input unit 120 , a display unit 130 , a storage unit 140 , and a control unit 150 .

[0043] The communication unit 110 is a processing unit that performs data communication with other devices via a network. For example, the communication unit 110 corresponds to a communication device or the like.

[0044] The input unit 120 is an input device for inputting various data to the image processing device 100 . For example, the input unit 120 corresponds to a keyboard, a mouse, a touch panel, and the like. The display unit 130 is a display device that displays data output from the control unit 150 . For example, the display unit 130 correspond...

Abstract

An image processing device (10) has a generation unit (11), a calculation unit (12), and a determination unit (13). A generation unit (11) generates an average image of difference images in video data based on the difference between two adjacent frames in one video data. A calculation unit (12) calculates a total of horizontal luminance values ​​of the average image for each point in the vertical direction of the average image. The specifying unit (13) selects a predetermined number of points from the points below the position of the vanishing point in the average image, and the points with a higher value of the second differential value of the sum of the luminance values, and selects a predetermined number of points from the selected points. Among the predetermined number of points, the boundary line between the bonnet and the road is determined.

Description

technical field [0001] The present invention relates to an image processing device and the like. Background technique [0002] If it is possible to notify the driver of potential accidents such as contact with passers-by immediately during driving, that is, the information of the location where the driver panic or surprise is likely to occur, then the occurrence of accidents can be prevented. In order to determine information on locations where potential accidents are likely to occur, data recorded by a driving recorder can be utilized. For example, the vehicle's position, shooting date and time, acceleration of the vehicle, speed of the vehicle, images in front of the vehicle, etc. are recorded in the driving recorder. [0003] Here, if only the numerical data such as acceleration recorded by the drive recorder is used to test the detection of potential accidents, a situation that is not originally a potential accident may be mistakenly detected as a potential accident. T...
