Depth cameras projecting irrelevant patterns

Abstract

The invention discloses a depth camera for projecting irrelevant patterns, comprising: a projection module, used to project a structured light pattern beam to a target area, and the structured light pattern is periodically arranged along a first direction; a collection module, arranged in A baseline at a certain distance from the projection module is used to collect the structured light pattern in the target area; there is an included angle between the first direction and the direction of the baseline. By designing the projection module, the projected structured light patterns are periodically arranged along a certain direction, and the direction is deflected at an angle with the baseline, so as to obtain speckle patterns with a high degree of irrelevance along the baseline direction.

Description

technical field [0001] The invention relates to the field of manufacturing electronic and optical components, in particular to a depth camera for projecting irrelevant patterns. Background technique [0002] The depth camera can obtain the depth information of the target to realize 3D scanning, scene modeling, and gesture interaction. Compared with the currently widely used RGB camera, the depth camera is gradually being valued by all walks of life. The combination of computers and other devices can realize somatosensory games to achieve the effect of two-in-one game and fitness. With the rapid popularization of mobile terminals such as mobile phones and tablets, there is an urgent need to embed depth cameras into mobile terminals. Mobile terminals with depth cameras can achieve more accurate and reliable face recognition and gesture interaction than ordinary RGB cameras. , and even functions such as AR. [0003] Compared with the traditional depth cameras used in TV, comp...
