Problems solved by technology

[0004] However, it is known that, in the occupant detection device described in the above-mentioned Patent Document 1, when using a camera to detect information related to a vehicle occupant, the larger the angle of view of the camera, the greater the amount of light imaged in the imaging area of ​​the image chip through the optical lens. It gets lower towards the periphery, and the deformed peripheral region of the image imaged in the imaging area of ​​the image chip is larger than the central region, thus reducing the detection accuracy of vehicle occupants
In particular, in the case of detecting the distance information of the vehicle occupant using a 3D camera in order to obtain detailed information such as the position, posture, physique, and movement of the vehicle occupant, a decrease in accuracy and deviation related to the distance of the vehicle occupant occur, and it is difficult to obtain high-precision get the desired information

no. 1 approach

[0066]As shown in FIG. 2 , the lighting device 130 of the first embodiment has a structure in which a plurality of light emitting lamps are arranged on a facing surface 130 a facing an object. The first light source 131 is formed by a plurality of light emitting lamps arranged in a central area 131a of the facing surface 130a, and the second light source 132 is formed by a plurality of light emitting lamps arranged in an outer peripheral area 132a of the outer periphery of the central area 131a. In the present embodiment, the number of light emitting lamps per unit area (arrangement density of light emitting lamps) in the first light source 131 is smaller than that of the second light source 132 (lower arrangement density). In addition, the following structure is formed: the light emitted from the first light source 131 and reflected by the object C passes through the central portion of the objective lens opening area of ​​the optical lens 114 of the camera 112 and enters the c...

[0073] Next, the structure of the lighting device 140 of the second embodiment is as shown in FIG. 3 . In this lighting device 140, a plurality of light emitting lamps are formed and divided (divided) into a first light source 141, a second light source 142, a third light source 143, a fourth light source 144, a fifth light source 145, a sixth light source 146, a seventh light source 147. A structure of nine light sources of the eighth light source 148 and the ninth light source 149. In this embodiment, the number of light emitting lamps per unit area (arrangement density of light emitting lamps) in each of the first to ninth light sources 141 to 149 is the same. In addition, in this lighting device 140 , it is possible to independently and variably control the light emission form (light quantity, light emission pattern) of each light source.

[0074] The specific control of the lighting device 140 having such a configuration will be described with reference to FIG. 4 . FIG....

[0082] Next, the structure of the lighting device 150 of the third embodiment is shown in FIG. 5 . In this lighting device 150 , a plurality of light emitting lamps are divided (divided) into three light sources of a first light source 151 , a second light source 152 , and a third light source 153 . In this embodiment, the first light source 151 is disposed facing the driver's seat area 151a, and constitutes a light source for distributing light to an object on the driver's seat (corresponding to the "driver's seat side light emitting unit" in the present invention). In addition, the second light source 152 is disposed facing the passenger's seat area 152a, and constitutes a light source for distributing light to an object on the passenger's seat (corresponding to the "passenger's seat side light emitting unit" in the present invention). Furthermore, the third light source 153 is disposed facing the rear seat area 153a, and constitutes a light source for distributing light to ...

Abstract

In order to provide a technology which is effective for precisely detecting information about an object (C) occupying a vehicle seat, an object detecting system (100) which is installed in a vehicle uses a camera (112) comprising an optical lens (114), a distance measuring image chip (116), and an illumination device (130) to detect information about the object (C) occupying the vehicle seat, the illumination device (130) is sectioned into a plurality of illuminants such as a first illuminant (131) and a second illuminant (132) so that the light emitting modes of the illuminants are controlled to be changed individually.An object detecting system, which is installed in a vehicle, uses a camera comprising an optical lens, a distance measuring image chip, and an illumination device to detect information about an object occupying a vehicle seat. The illumination device is sectioned into a plurality of illuminants, such as a first illuminant and a second illuminant, so that the light emitting modes of the illuminants are controlled to be changed individually.

Description

technical field [0001] The present invention relates to an object detection system mounted on a vehicle, in particular to a technique for detecting information related to an object on a vehicle passenger seat. Background technique [0002] Conventionally, various techniques are known for detecting information on an object seated on a passenger seat of a vehicle using an imaging unit such as a camera. For example, Patent Document 1 below discloses a configuration of an occupant detection device that detects the position of a vehicle occupant using a single camera installed in front of the vehicle occupant. [0003] Patent Document 1: JP-A-2003-294855 [0004] However, it is known that, in the occupant detection device described in the above-mentioned Patent Document 1, when using a camera to detect information related to a vehicle occupant, the larger the angle of view of the camera, the greater the amount of light imaged in the imaging area of ​​the image chip through the o...
