Title:
DEPTH INFORMATION DETERMINATION METHOD AND APPARATUS, DEVICE, STORAGE MEDIUM, AND PROGRAM PRODUCT
Document Type and Number:
WIPO Patent Application WO/2022/170508
Kind Code:
A1
Abstract:
The present application provides a depth information determination method and apparatus, a device, a storage medium, and a program product. The method comprises: controlling a light source to alternately emit first emitted light of a first modulation frequency and second emitted light of a second modulation frequency to an object; detecting first reflected light and second reflected light generated by the object; and calculating depth information of the object according to two adjacent frames of reflected light and the modulation frequency of the latter of the two adjacent frames of reflected light. In the present application, the modulation frequency of the emitted light used is greater than 50 M, so that the problem of poor SNR can be avoided, and the success rate of unwrapping is improved; in addition, when the depth information is determined, every two adjacent frames of reflected light can be determined to obtain a piece of depth information, and therefore, a greater number of pieces of depth information can be obtained, thereby helping to reduce power consumption.
