Detailed Description
In order to make the objects, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
It should be noted that step numbers such as S1 and S2 are used herein for the purpose of more clearly and briefly describing corresponding contents, and do not constitute a substantial limitation on the sequence, and those skilled in the art may perform S4 first and then S3 in the specific implementation, but these should be within the protection scope of the present application.
As shown in fig. 1, a seat adjusting method according to an embodiment of the present invention includes the steps of:
and S11, acquiring the posture of the operator, and judging whether the vehicle state is a forward state or a working state according to the posture of the operator.
And S13, controlling the angle position of the seat according to the vehicle state.
And S15, acquiring the eye position and the optimal visual field position of the operator, judging whether the eyes are positioned at the optimal visual field position, and controlling the height position of the seat according to whether the eyes are positioned at the optimal visual field position.
In this embodiment, step S11 specifically includes: the method comprises the steps of obtaining positions of human eyes, judging whether the two eyes are looking at the front of a vehicle, judging that the vehicle state is a forward state when the two eyes are looking at the front of the vehicle, and judging that the vehicle state is a working state when the two eyes are not looking at the front of the vehicle. The forward state of the vehicle means a state in which the vehicle travels forward, and the operating state of the vehicle means a state in which the vehicle performs work such as excavation or drilling.
Specifically, acquiring the positions of human eyes, and judging whether the two eyes are looking at the front of the vehicle specifically may be: the position relation between the two-eye connecting line of the operator and the front window is obtained, when the two-eye connecting line is parallel to the front window, as shown in fig. 2, the vehicle state is judged to be a forward state, and when the extension line of the two-eye connecting line is intersected with the extension line of the front window, as shown in fig. 3, the vehicle state is judged to be a working state. When the connecting line of the two eyes is parallel to the front window, the vehicle is in a forward state when the eyes look forward, and when the extension line of the connecting line of the two eyes is intersected with the extension line of the front window, the vehicle is in a working state when the eyes look at the working head (such as a lifting appliance and a drilling tool). It can be understood that obtaining the positions of the human eyes and judging whether the two eyes are looking ahead of the vehicle may also be: and acquiring the positions of the eyes, judging whether the two eyes are symmetrical, judging that the vehicle state is a forward state when the two eyes are symmetrical, and judging that the vehicle state is a working state when the two eyes are asymmetrical.
Specifically, the step of acquiring the position of the human eyes of the operator specifically includes:
acquiring pictures of two eyes of an operator;
processing pictures of two eyes;
and determining the coordinates of the two eyes by using a human eye positioning algorithm according to the processed pictures of the two eyes so as to obtain the positions of the human eyes. Specifically, after a human face region is detected through gray scale integration, human eye feature points are searched by utilizing gray scale and gradient features in the region to determine the human eye position.
It is to be understood that in step S11, whether the vehicle state is the forward state or the operating state may also be determined according to other physical characteristics of the operator. For example, a face image may be acquired first, and then the vehicle state may be determined according to whether the face image is a front face or a side face of the face, where when the face is the front face, it indicates that the eyes are looking forward and the vehicle is in a forward state, and when the face is the side face, it indicates that the eyes are looking at a working head (e.g., a hanger or a drill tool), and the vehicle is in a working state.
In this embodiment, step S13 specifically includes: when the vehicle state is the advancing state, the seat is controlled to be at the initial angle position, and when the vehicle state is the working state, the seat is controlled to rotate a certain angle relative to the initial angle position. Specifically, when the seat is at the initial angle position, the seat is over against the front of the vehicle, and the human eyes can see the front, so that the vehicle can be conveniently controlled to move forwards; after the seat rotates a certain angle, the seat is over against the working head, and human eyes also look at the working head, so that the vehicle can be conveniently controlled to carry out digging, drilling and other work.
Specifically, when the seat is controlled to rotate by a certain angle relative to the initial angle position, the included angle between the connecting line of the two eyes and the connecting line from the center A of the working head to the midpoint B of the connecting line of the two eyes is 90 degrees, so that the human eyes can look at the working head.
In this embodiment, step S15 specifically includes:
s152, acquiring an optimal view point curve as an optimal view range. Specifically, the optimal sight point may be obtained by pre-calculation, for example, by analysis of human-machine simulation analysis software. The drivers 'cabs of different models and brands are designed differently, and the corresponding optimal view point curves are different, so that the corresponding optimal view point curves need to be acquired for different drivers' cabs.
S153, acquiring the midpoint position of the two-eye connecting line, judging whether the midpoint position of the two-eye connecting line is on the optimal view point curve, if so, controlling the height position of the seat to be unchanged, and if not, controlling the height position of the seat to be adjusted to enable the midpoint position of the two-eye connecting line to be on the optimal view point curve. Specifically, the midpoint of the connecting line of the two eyes can be translated in the height direction of the seat to intersect with the curve of the optimal visual field point, and the intersection point is the current optimal visual field position.
Specifically, referring to fig. 4, L1 is an optimal view point curve, since the general position of the seat in the left-right direction of the vehicle is not changed, the optimal view point curve L1 is a spatial curve with a constant x value, and for the same cab, when the front-back position of the seat is changed or the body size of the operator is changed, the midpoint position of the two eyes generally only changes up and down, and does not change the left-right position, that is, y and z change, and x does not change, so the midpoint position of the two-eye connecting line is always in the shadow plane in the figure. When the coordinate of the midpoint of the two-eye connecting line is a (X1, Y1, Z1), the Y-axis coordinate of the current optimal view point should also be Y1, and the X-axis coordinate should also be X1, so that the point b on the optimal view point curve is the current optimal view point, and the coordinate of the point b is a (X1, Y1, Z2), at this time, the height position of the seat is controlled, that is, the seat is controlled to be lifted (i.e., moved along the Z axis), so that the midpoint of the two-eye connecting line reaches the point b, that is, the current optimal view point is reached.
It is understood that step S15 may be performed first, and then steps S11 and S13 may be performed, that is, the angular position of the seat may be adjusted first, and then the height position of the seat may be adjusted, or the height position of the seat may be adjusted linearly, and then the angular position of the seat may be adjusted.
According to the seat adjusting method, the current state of the vehicle can be judged according to the posture of the operator, and then the seat is controlled to rotate, so that the operator can face the front or the working head under different working conditions, the body posture (such as body twisting or head turning) does not need to be adjusted, and the comfort of the operator is greatly improved; meanwhile, the height of the seat can be automatically adjusted according to different heights of operators, so that the operators always have the best view field, and the comfort and the safety of operation can be greatly improved.
