Problems solved by technology

However, in the installation of the traditional vehicle-mounted binocular vision system, the parameters of the camera will not be changed after the calibration stage is set.
However, in actual operation, the vehicle will vibrate, bump, accelerate to overtake, and the vehicle body shakes significantly during driving, and these processes will cause the position of the camera to change. If it is not adjusted in time, it will affect the The image captured by the camera affects the subsequent calculation and analysis process and results

Embodiment Construction

[0041] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0042] The invention provides a driver's feature point measurement device based on binocular vision, which is installed inside a car. Generally, after the camera is calibrated, the mutual positional relationship between the two cameras and the focal length of the camera cannot be changed, but due to the driver's height, the position of the driver's seat may change, and there will be vibrations when the car is driving, etc. When the vehicle condition occurs, the fixed camera and focal length cannot accurately capture the driver's human body feature points in different situations. However, the device of the present invention can control the positional relationship of the camera relative to the driver according to the specific vehicle conditions and the driver's situation, witho...

Abstract

The invention discloses a driver feature point measuring device based on binocular vision, capable of detecting the running condition of an automobile and the characteristics of a driver, and changingthe position relation of the camera relative to the driver by adjusting the length of an output shaft of a motor and the rotation angle of a camera. The invention further provides a control method for driver feature point measuring based on binocular vision, and the positions of the two cameras and the length of the output shaft of the motor can be regulated and controlled on the basis of a BP neural network, so that the measuring precision and accuracy can be improved.

Description

technical field [0001] The invention relates to the field of non-contact measurement of three-dimensional coordinates of driver's human body feature points, in particular to a driver's feature point measurement device based on binocular vision and a control method thereof. Background technique [0002] A good interior design of the car cab is of great significance to the driver's comfort and safety, and the position coordinates of the driver's body feature points are the key to the interior design of the cab. There are three existing three-dimensional measurement methods: destructive, contact and non-contact. For the measurement of human body feature points, only contact and non-contact measurement can be used. Among them, the most common method of contact measurement is to use the three-coordinate measuring machine that emerged in the 1960s. The three-coordinate measuring machine has high measurement accuracy, but it is used for The measurement of human body feature points...
