Problems solved by technology
[0002] Some existing laser transmitters emit lasers with strong focusing signals, and the energy of these lasers will attenuate after passing through collimation elements and diffraction elements, so that the signal strength is lower than the threshold of harm to the human body.
These laser emitters are usually composed of glass or other easily broken parts. Once the lens is broken in case of falling, the laser will be emitted directly, irradiating the user's body or eyes, causing serious safety problems

The invention discloses a structured light projective module, an image capturing apparatus and electronic equipment. The structured light projective module comprises a laser transmitter, an optical assembly and a circuit board assembly; the laser transmitter is used for transmitting laser; the optical assembly is arranged on the light emitting optical path of the laser transmitter, and the laser passes through the optical assembly to form a laser pattern; the optical assembly is provided with a detection element which is used for outputting an electric signal for detecting whether the opticalassembly is cracked or not; the circuit board assembly comprises a first connecting board, a bent board and a second connecting board which are connected in sequence; the detection element is connected with the first connecting board through the second connecting board and the bent board; and the laser transmitter is arranged on the first connecting board. By virtue of the embodiments of the structured light projective module, the image capturing apparatus and the electronic equipment, electrical connection of the detection element and a processor can be realized through the bendable circuit board, so that the processor can judge whether the optical assembly is cracked or not according to the electric signal output by the detection element, thereby improving the use safety of the structured light projective module.
Description
technical field [0001] The invention relates to the technical field of three-dimensional imaging, in particular to a structured light projection module, an image capture device and electronic equipment. Background technique [0002] Some existing laser transmitters emit lasers with strong focused signals, and the energy of these lasers will be attenuated after passing through collimation elements and diffraction elements, so that the signal strength is lower than the threshold of harm to the human body. These laser emitters are usually composed of glass or other easily broken parts. Once the lens is broken in case of falling, the laser will be emitted directly to irradiate the user's body or eyes, causing serious safety problems. Contents of the invention [0003] Embodiments of the present invention provide a structured light projection module, an image capture device, and electronic equipment. [0004] The structured light projection module according to the embodiment o...
