  • Publication number: 20240221163
    Abstract: Disclosed is a method and apparatus for measuring a deviation angle of a gaze position based on 3D reconstruction. A face image sequence of a testee is acquired. Covering conditions of the face image sequence are obtained. Key frame images are determined and input into a second neural network to obtain feature point heat maps that are converted into facial feature point coordinates. An objective function is constructed. A head pose corresponding to the key frame images is obtained. An eyeball position is initialized. An eyeball rotation angle of a reference gaze position is set as a preset angle. 3D coordinates of an eyeball in a reference gaze position image in a head coordinate system is solved. 3D coordinates of an eyeball in a to-be-measured image in the head coordinate system are fixed. An eyeball rotation angle is solved. A deviation angle of a gaze position is obtained.

  • Publication number: 20240221423
    Abstract: Disclosed are a method and apparatus for measuring a gaze difference based on gaze estimation. Video data of a testee gazing at a visual target is obtained, and a face image sequence is obtained from the video data. The face image sequence is input into a first neural network for key frame extraction to obtain a first and second gaze position face image. The face images are input into a second neural network for facial feature point extraction. Cropping is performed based on facial feature point coordinates to obtain a first and second eye region image. A gaze difference estimation network is trained to obtain a trained gaze difference estimation network. The first and second eye region images are input into the trained gaze difference estimation network to obtain a predicted gaze difference between the first and second eye region images.

  • Patent number: 10784389
    Abstract: The invention relates a full-laser scribing method for a flexible stainless steel substrate solar cell module, comprising: preparing an insulating layer and a molybdenum layer on a stainless steel substrate in sequence; using a laser I to scribe the prepared insulating layer and molybdenum layer to form a first scribed line (P1); preparing the following film layers in sequence on the molybdenum layer in which P1 has been scribed: a CIGS layer, a cadmium sulfide layer and an intrinsic zinc oxide layer; using a laser II to make scribe and thus form a second scribed line (P2), wherein the second scribed line P2 is parallel with the first scribed line P1; and preparing an aluminum-doped zinc oxide layer on the intrinsic zinc oxide layer in which P2 has been scribed, and using a laser III to make scribe and thus form a third scribed line (P3), wherein the third scribed line P3 is parallel with the first scribed line P1.
