Problems solved by technology

[0003] The on-site monitoring equipment disclosed in the above-mentioned second to fifth patent documents only utilizes an on-board image capture device installed on the subject vehicle to generate a top view, and since the vehicle is very small in the captured image, it is difficult to Vehicles are accurately displayed on the screen
In particular, since it is difficult to spot an approaching vehicle in a top view, a vehicle approaching the subject vehicle at high speed may not be recognized as a warning target, and the remaining time until close contact is reached is very small

Embodiment Construction

[0022] FIG. 1 is a block diagram showing an example of an electrical configuration of a vehicle site monitoring device of the present invention. In the present embodiment, the vehicle site monitoring device 1 mainly includes an ECU which is in charge of overall control. In the present embodiment, the ECUs are composed of an image ECU 50, a risk assessment ECU 70, and a warning output control ECU 90 connected through a network. Each of the ECUs 50, 70, 90 is constituted by the following sections respectively connected via buses: a CPU; a ROM storing software executed by the CPU; a RAM as a work memory; and an input and output (I / O) section. That is, these ECUs are known types of microcomputers.

[0023] The in-vehicle camera group 11 is connected to the image ECU 50 . In addition, a road-vehicle communication unit 40 composed of a wireless transmitter-receiver is also connected to the ECU 50 through a communication interface (not shown). Furthermore, a GPS 4 and a radar 3 fo...

Abstract

A field watch apparatus for use in a subject vehicle acquires a road image from a roadside capture unit located around the subject vehicle on a road and, based on the acquired image, generates an overhead view of a field around the subject vehicle in an intuitively recognizable manner by including a distant surrounding vehicle in the view, thereby providing a precisely understandable view of the field around the subject vehicle for the ease of satisfactorily identifying the distant surrounding vehicle without being compromised by the position of the roadside capture unit.

Description

technical field [0001] The present disclosure generally relates to a field monitoring / observation device for use in a vehicle. Background technique [0002] In recent years, various technologies for monitoring the scene around the automobile have been disclosed. For example, the device described in the republished patent document WO00 / 64175 (US7,161,616) has a plurality of photographing devices (cameras) on the subject vehicle. These images are synthesized from viewpoints to generate a top view of the subject vehicle, and the top view is displayed on the device. In addition, Japanese patent documents such as JP-A-2003-312415, JP-A-2005-5978, JP-A-2002-232948, JP-A-2006-107521, and JP-A-2006-282111 disclose a field A monitoring device for monitoring surrounding vehicle conditions around a traveling subject vehicle in a top view by applying the technology disclosed in the first patent document. [0003] The on-site monitoring equipment disclosed in the above-mentioned secon...
