Embodiment 1

[0023] In this embodiment, a head and shoulders region positioning method is provided, figure 1 is a flow chart of the head and shoulders positioning area according to an embodiment of the present invention, such as figure 1 As shown, the process includes the following steps:

[0024] Step S101: Acquiring video images in the cab. At present, most cars are equipped with a front-facing camera that records driving conditions. This camera can collect images of the driver's overall area, and can clearly capture the driver's behavior without affecting the driver's driving safety;

[0025] Step S102: Input the video image into the head and shoulders detection model, locate the head and shoulders area in the video image through the output of the head and shoulders detection model; wherein, the head and shoulders detection model is obtained through multiple head and shoulders training sets and multiple It is obtained by training the classifier on the non-head and shoulders training s...

Embodiment 2

[0031] This embodiment also provides a device for locating the head and shoulder area, which is used to implement the above embodiments and preferred implementation modes, and what has already been described will not be repeated. As used below, the term "module" may be a combination of software and / or hardware that realizes a predetermined function. Although the devices described in the following embodiments are preferably implemented in software, implementations in hardware, or a combination of software and hardware are also possible and contemplated.

[0032] This embodiment provides a head and shoulder area positioning device, such as figure 2Shown, comprise acquisition module 21, be used to obtain the video image in the cab; Output module 22, be used for this video image input to head and shoulders detection model, locate the head and shoulders in this video image by the output of this head and shoulders detection model area; wherein, the head and shoulders detection mod...

Abstract

The invention provides a head and shoulder region positioning method and device. The method comprises the steps that a video image in a cab is acquired; the video image is input into a head and shoulder detection model; and a head and shoulder region in the video image is positioned through the output of the head and shoulder detection model, wherein the head and shoulder detection model formed by training a classifier through a number of head and shoulder training sets and a number of non-head-shoulder training sets. According to the invention, the problems of low project detection rate and low detection precision, which are caused by the influence of objective conditions such as ambient light and the like in the prior art, of head and shoulder region positioning are solved; the head and shoulder region is accurately and effectively positioned; and the robustness is great.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a method and device for locating a head and shoulder area. Background technique [0002] Intelligent transportation system is the development direction of the future transportation system, and it is also a frontier research topic in the field of transportation in the world. At present, most cars are equipped with front-facing cameras that record driving conditions. This camera can collect images of the entire area where the driver is located, and can clearly capture the behavior of the driver without affecting the driving safety of the driver. By locating the driver's head and shoulder area, the driver's precise driving state can be obtained, and its behavior can be monitored to ensure safe driving. However, due to the influence of objective conditions such as ambient light and darkness, the head and shoulders area positioning has the problems of low item dete...
