Problems solved by technology

However, the accuracy of the distance information of the target object obtained by TOF technology or structured light technology is poor, which is not conducive to obtaining high-precision 3D depth images and cannot meet user needs. Therefore, it is necessary to seek a method that can obtain high-precision 3D depth images. The camera module is especially important

Abstract

The invention provides a confocal camera module and electronic equipment. The confocal camera module comprises a module support, a transmitting module and a receiving module, wherein the transmitting module and the receiving module are arranged on the module support. The transmitting module comprises a light emitting part, a first light adjusting part and a first dispersion lens which are sequentially arranged in the light emitting direction, the first dispersion lens is used for enabling light to generate dispersion and emit the light to a target object, the first light adjusting part forms a first light transmitting area, and the first light adjusting part and the first dispersion lens form a light emergent light path; the receiving module comprises a receiving lens, a second light adjusting part and a spectrum confocal sensor which are sequentially arranged in the light incidence direction, the receiving lens is used for receiving light reflected by the target object, the second light adjusting part is provided with a second light transmitting area, the receiving lens and the second light adjusting part form a light incidence light path, and the light incident light path and the light emergent light path are conjugate light paths. Through the confocal camera module, a high-precision 3D depth image can be obtained.

Description

technical field [0001] The present disclosure relates to the technical field of electronic equipment, in particular to a confocal camera module and electronic equipment. Background technique [0002] With the development of technologies such as AR and VR, 3D imaging technology has been applied to electronic devices and is favored by people. For example, TOF (Time of Flight, time of flight) technology or structured light technology is widely used in 3D imaging of electronic devices. However, the accuracy of the distance information of the target object obtained by TOF technology or structured light technology is poor, which is not conducive to obtaining high-precision 3D depth images and cannot meet user needs. Therefore, it is necessary to seek a method that can obtain high-precision 3D depth images. Camera modules are especially important. Contents of the invention [0003] The present disclosure provides an improved confocal camera module and electronic equipment. [...
