Embodiment Construction

[0089] Due to the complex light in the vehicle environment and the different eye positions of different drivers, the line-of-sight estimation system in the car cannot accurately estimate the direction of the driver's line of sight. In order to improve the accuracy of the line of sight estimation system for the driver's line of sight estimation, Figure 1b shows a possible implementation, such as Figure 1b As shown, the user 06 is made to sit in front of a specific screen 08 and look at a series of points displayed on the screen, and the camera 07 placed in front of the screen records the points on the screen with the eyes to obtain the user's line of sight; Modeling is carried out to calculate the Kappa angle of the user's eyeball, thereby realizing the calibration of the user's line of sight direction and improving the accuracy of line of sight direction estimation.

[0090] The above-mentioned implementation has the following defects: 1. It is only applicable to indoor sce...

Abstract

The invention relates to the field of intelligent driving, in particular to a target position determining method, a determining device and a determining system, and the method comprises the steps: obtaining the sight direction of a first user in a cabin; determining a target position pointed by the sight line direction of the first user according to the sight line direction of the first user and an estimation model; wherein the estimation model is used for representing the probability that the sight line direction of a user in a cabin points to a target position, the estimation model is obtained by training according to the corresponding sight line direction when a second user executes a driving operation and a preset target position corresponding to the driving operation, and the preset target position comprises the target position. According to the invention, the target position of the sight line of the user can be accurately determined in the cabin in the vehicle with complex light, and the problem that the target position of the user is difficult to accurately obtain due to complex light in the cabin in the vehicle is solved.

Description

technical field [0001] The present application relates to the field of smart cars, in particular to a method, device and system for determining a target position. Background technique [0002] like Figure 1a As shown, the optical axis OA of the human eye is a line connecting the points on the cornea 01 , crystalline lens 02 , vitreous body 03 and retina 04 of the eyeball 010 in turn reflected by the point light source. The visual axis VA of the human eye is the line connecting the fovea 05 on the retina 04 and the point light source when the human eye is looking at the point light source, which can represent the line of sight direction of the human eye. The visual axis VA of the human eye and the optical axis OA have an included angle, which is called a Kappa angle, and the Kappa angle can be regarded as constant. When estimating the line of sight direction of the human eye, it is necessary to first estimate the direction of the optical axis OA, and then calculate the dire...
