The invention discloses a depth calibration method, which is applied to a terminal. The terminal comprises a depth acquisition device, wherein the depth acquisition device comprises a laser projectorand an infrared camera. The depth calibration method comprises the steps of: controlling the laser projector to project laser to a predetermined plane at a plurality of projection distances respectively; controlling the infrared camera to acquire a plurality of laser patterns modulated by means of the predetermined plane at the plurality of projection distances respectively; acquiring installationdeviation of the laser projector according to the plurality of laser patterns; and calibrating depth information acquired by means of the depth acquisition device according to the installation deviation. The invention further discloses a depth calibration device, the terminal, a non-volatile computer readable storage medium and computer equipment. After acquiring the installation deviation of thelaser projector by utilizing the plurality of laser patterns, the depth information acquired by means of the depth acquisition device is calibrated according to the installation deviation, error of the depth information caused by the installation deviation of the laser projector is eliminated, and the accuracy of the depth information is improved.
Description
Technical field [0001] The present invention relates to the field of three-dimensional imaging technology, in particular to a depth calibration method, a depth calibration device, a terminal, a non-volatile computer readable storage medium and computer equipment. Background technique [0002] After the laser projector in the mobile phone is replaced, the calibration data corresponding to the new laser projector needs to be burned into the mobile phone so that the laser projector can be used normally. The calibration data can only be used to obtain accuracy after the laser projector is installed in strict accordance with the requirements. When the installation position of the laser projector cannot meet the requirements, the accuracy of the depth information obtained according to the calibration data is low. Summary of the invention [0003] Embodiments of the present invention provide a depth calibration method, a depth calibration device, a terminal, a non-volatile computer reada...
