Example Embodiment

[0015] Example 1

[0016] An embodiment of the vehicle driving assistance device in this application may refer to figure 1 , including infrared pyroelectric sensor 101, multi-spectral camera 102, processor 103 and display device 104.

[0017] The infrared pyroelectric sensor 101 is used as a first detection device for detecting objects within a first distance range and generating a corresponding first detection signal. The first distance is the sensing distance of the infrared pyroelectric sensor 101 . In other embodiments, other devices with object distance detection capability may also be used as the first detection device, such as sonar or radar.

[0018] The multispectral camera 102 is used as a first image acquisition device for acquiring images and generating corresponding image data. The photosensitive chip of the multispectral camera 102 can simultaneously sense infrared and visible light, and the collected infrared image and visible light image overlap in size and o...

Example Embodiment

[0031] Example 2

[0032] For another embodiment of the vehicle driving assistance device in this application, reference may be made to image 3 , Compared with Embodiment 1, the difference is that in addition to including infrared pyroelectric sensor 201, multi-spectral camera 202, processor 203 and display device 204, it also includes sound alarm device 205 and vibration alarm device 206 used as an alarm device.

[0033] The infrared pyro sensor 201, the multi-spectral camera 202 and the display device 204 are similar to the infrared pyro sensor 101, the multi-spectral camera 102 and the display device 104 in Embodiment 1, and will not be repeated here. In addition to the content of the processor 103 described in Embodiment 1, the processor 203 is also signal-connected to each alarm device, and used to generate an alarm instruction according to the first detection signal, so as to trigger each alarm device to generate a corresponding alarm action. The sound alarm device 205...

Example Embodiment

[0037] Example 3

[0038] For another embodiment of the vehicle driving assistance device in this application, reference may be made to Figure 5 , including a two-stage infrared pyroelectric sensor 301, a multi-spectral camera 302, a processor 303, a display device 304, a sound alarm device 305 and a vibration alarm device 306.

[0039] The multispectral camera 302 and the display device 304 are similar to the multispectral camera 102 and the display device 104 in Embodiment 1, and will not be described again.

[0040] The two-stage infrared pyroelectric sensor 301 is used as a first detection device, and is composed of two groups of passive infrared (PIR, Passive Infrared) sensors whose detection distances are a first distance range and a second distance range respectively, and the second distance range is greater than the first distance. scope. In this case, the first detection device can detect objects within the first and second distance ranges, respectively, and genera...

Abstract

The invention discloses equipment and a method for assisting in vehicle driving. The equipment comprises a first detection device for detecting an object in a first distance range and generating a corresponding first detection signal, a first image acquisition device for acquiring an image and generating corresponding image data, and a processor which is connected with the first detection device and the first image acquisition device by signals and is used for controlling the first image acquisition device to acquire the image according to the first detection signal. As the detection device is matched with the image acquisition device, the image acquisition device is triggered to run when the object in the defined distance range is detected, and is not required to be kept started all the time, so that the requirements on equipment are lowered.

Description

technical field [0001] The present application relates to the technical field of automobile safety, in particular to a vehicle driving assistance device and method. Background technique [0002] With the development of economy and society, the wide use and popularity of vehicles are getting higher and higher, and the safety accidents caused by vehicles are also increasing. To reduce the possibility of accidents due to human sensory factors such as fatigue or limited visual range, various driving aids have been proposed, including: [0003] 1. Active alarm products can actively alarm according to the actual situation. For example, the Chinese invention patent with the publication number CN1586945 provides radar-based rear-end collision avoidance equipment. This type of equipment can give a voice alarm when the vehicle and the object in front are close to a dangerous distance, but cannot distinguish the type of object (for example, it is an object). or people). [0004] 2. ...
