no. 1 Embodiment approach

[0035] In this embodiment, a case where the outside world recognition device of the present invention is applied to a system capable of simultaneously performing vehicle detection, pedestrian detection, and road sign recognition in front of the own vehicle using images from a stereo camera mounted on the vehicle will be described. as an identification application.

[0036] First, use figure 1 , the outline of the outside world recognition device in this embodiment will be described.

[0037] figure 1 It is a block diagram of an apparatus for realizing the present invention. The stereo camera 100 captures images of the front of the vehicle from a vehicle on which the stereo camera 100 is mounted, and has a pair of left and right imaging units 101 and 102 for imaging partially overlapping ranges. The stereo camera 100 is constituted by cooperation of hardware such as a microcomputer including an arithmetic device and storage devices such as ROM and RAM, and a software program...

no. 2 Embodiment approach

[0103] Next, the following will use Figure 13 , and the second embodiment of the present invention will be described.

[0104] The present embodiment is characterized in that it is configured to detect pedestrians in the entire periphery of the vehicle by connecting four cameras that capture images of the front, rear, left, and right sides of the vehicle to the stereo camera. The camera 1401 , the camera 1402 , the camera 1403 , and the camera 1404 are single-lens cameras installed on the vehicle, and are respectively installed at the front, rear, left, and right sides of the vehicle. The images captured by the left imaging unit 101 and the right imaging unit 102 of the stereo camera 100 and the images captured by the cameras 1401 , 1402 , 1403 , and 1404 are sent to the image area cutting unit 103 .

[0105] In the image area cutting unit 103, a part of the image captured by the left imaging unit 101, the right imaging unit 102, the camera 1401, the camera 1402, the camera ...

Abstract

The present invention provides an outside world recognition device that can obtain detection results with required accuracy when detecting various objects using captured images. The external recognition device of the present invention includes: a plurality of processing units, which perform image processing on images; a recognition application storage unit, which stores a variety of recognition applications according to the types of objects, and the recognition applications are processed by the plurality of processing units. At least one processing unit processes to identify an object; an external information acquisition unit acquires external information including at least one of external environment information or self-vehicle behavior information; and a selection unit selects from the identification application storage unit based on the external information. At least one recognition application is selected, and a processing unit for processing the selected recognition application is selected from a plurality of processing units.

Description

technical field [0001] The invention relates to an outside recognition device for detecting objects according to image information outside the car. Background technique [0002] In order to realize the safe driving of the vehicle, the device that detects the dangerous situation around the vehicle and automatically controls the steering, acceleration and braking of the vehicle in order to avoid the detected dangerous situation has been researched and developed, and some vehicles have been equipped with . Among them, a system that uses a camera mounted on a vehicle to detect an obstacle such as a vehicle or a pedestrian in front of the vehicle to warn the driver or perform automatic braking is effective in improving vehicle safety. [0003] In a system that detects obstacles around the vehicle using images from a camera mounted on the vehicle, the types of detection objects tend to increase, and it is necessary to inspect multiple types of objects at the same time. Therefore...
