Problems solved by technology

[0006] However, in safety devices such as turning mirrors, there are problems that they are installed in places where it is difficult to see from a moving car, or are difficult to see due to the problem of the installation angle, or the road cannot be recognized due to light reflection such as sunlight. status

Example Embodiment

[0099] Example 1

[0100] figure 1 It is a block diagram showing the overall configuration of the intersection situation recognition system according to Embodiment 1 of the present invention.

[0101] The intersection recognition system in the first embodiment is composed of a camera 101 and a vehicle-mounted device 108. The imaging device 101 and the vehicle-mounted device 108 each have a unique identification number (ID). Wireless communication such as light or radio waves is used for communication between the in-vehicle device 108 and the imaging device 101. In addition, the term "identification number" also includes a symbol other than a number or an identification code composed of a combination of a number and a symbol other than a number.

[0102] The imaging device 101 is composed of: an imaging unit 102, which has a lens, imaging elements, an analog front end that converts the captured image into a digital imaging signal, etc.; and performs predetermined processing on the i...

Example Embodiment

[0118] Example 2

[0119] Previously, it was assumed that the locations and IDs of the imaging devices installed in the whole country were recorded in advance in the imaging device search unit 113, but an example in the case of not recording in advance is described here.

[0120] Picture 9 It is a block diagram showing the overall structure of the intersection situation recognition system in the second embodiment of the present invention. As the overall structure of Example 1 figure 1 In this, a transmitting unit 901 and an imaging device setting information receiving unit 902 are newly added as blocks. Provided figure 1 The newly added block of the imaging device 101 is the imaging device 101A, which is set in figure 1 The newly added block in the in-vehicle device 108 is the in-vehicle device 108A.

[0121] The camera 101A is relative to figure 1 In the imaging device 101, a transmitting unit 901 that transmits the location information of the device, the direction of imaging, and...

Example Embodiment

[0125] Example 3

[0126] In Embodiment 1, when images are received from multiple imaging devices, all images are displayed in the same way, but there are Figure 11A When the illustrated intersection 1106 where obstacles 1104 and 1105 are present and two imaging devices 1101 and 1102 are installed, the priority of the image may change depending on which direction the host vehicle 1103 is traveling in. For example in Figure 11A When the vehicle 1103 wants to go straight at the intersection 1106 and when it wants to turn right, both the left and right images have the same priority, but when the intersection 1106 wants to turn left, the camera 1101 The captured image of the right road has a higher priority than the image of the left road captured by the imaging device 1102. At this time, it is best to give priority to the image on the right. Figure 11B The relationship between the priority of the left and right shooting direction at the intersection with the traveling direction o...

Abstract

An intersection situation confirmation system which allows reliable grasp of a road situation having a blind area when a vehicle such as an automobile passes through an intersection blind due to an obstacle. An imaging device (101) which captures an image of a direction blind from the vehicle entering the intersection by an imaging section (102) and transmits the captured image to the vehicle entering the intersection is installed in the vicinity of the blind intersection. Moreover, an in-vehicle device (108) which receives the image from the imaging device (101) and displays the image on a display device (111) is installed to the vehicle entering the intersection. The in-vehicle device (108) searches for the imaging device identification number of the imaging device (101) installed at the intersection being entered, transmits the imaging device identification number to the imaging device (101), and displays the received intersection image only when the imaging device identification number received with the intersection image from the imaging device (101) and the searched imaging device identification number match.

Description

technical field [0001] The present invention relates to an intersection situation recognition system that supports safety confirmation when driving a vehicle, and in particular relates to a system that can recognize the movement status of vehicles, people, etc. The system's intersection condition recognition system. Background technique [0002] Usually, at intersections such as curves with poor visibility, T-shaped roads, and intersections, safety devices such as curve mirrors are installed to ensure the field of view in order to allow vehicles such as bicycles, bicycles, and cars to pass safely. [0003] In addition, a safety confirmation device has been developed in which a camera is embedded in the front bumper of a car, and the camera takes a picture of a road that constitutes a blind spot, and displays it on a car navigation monitor in the car. According to this device, even when the road condition that constitutes a blind spot cannot be grasped, such as an intersecti...
