Abstract
Disclosed is a line-of-sight detection method, including a step SA1 and a step SA2. The step SA1 performs a dynamic-threshold-to-switch action to correct the error of the data generated in the previous facial feature detection step. Furthermore, the step SA2 performs an eye-ROI-filtering action serving as a pretreatment step to filter a plurality of eye-ROI images and establish a sample set.
Claims20
A line-of-sight detection method, including:
- a step SA1 that performs a dynamic-threshold-to-switch action to correct errors of data generated in a previous facial feature detection step;
- and
- a step SA2 that performs an eye-ROI-filtering action serving as a pretreatment step to filter a plurality of eye-ROI images and establish a sample set.
Aline-of-sight detection method, comprising:
- a step S1 that executes a face detection;
- a step S2 that executes a facial landmark detection;
- a step SA1 that executes a dynamic-threshold-to-switch action;
- a step S3 that executes a head pose estimation;
- a step S4 that executes a pupil detection;
- and
- a step S5 that executes a gaze estimation.
