To sum up, on the premise of not affecting to obtain the infrared texture image comprising depth data of monitoring space, using many
Individual infrared coding projection arrangement to the scheme that the different projected areas of monitoring space project projects dress with using single infrared coding
Put to the scheme of whole monitoring space projection and compare, in the case of the operating power identical of infrared coding projection arrangement, adopt
Infrared coding projection arrangement in distributed projection scheme can project farther infrared beam, and infrared beam projects monitoring
The intensity of illumination in space is stronger.In addition, for the scheme using multiple infrared coding projection arrangements, a working cycle
Interior, each infrared coding projection arrangement only needs to work portion of time, i.e., each infrared coding projection arrangement works at each
There is certain power-off time in cycle, this way it is possible to avoid the device heating caused because working long hours is to infrared pumped FIR laser
The aging grade that projection arrangement is caused is damaged so that each infrared light generator can as far as possible reach its service life.
Further, infrared coding projection arrangement can be made up of infrared light generator and optical system.Infrared light occurs
Device can produce infrared light, and the infrared light that infrared light generator is produced can be processed, become to carry by optical system
The infrared beam of texture.Wherein, according to actual needs, optical system can have various structures.When optical system is using different
During structure, the infrared light that infrared light generator sends can become the infrared beam with different texture after optical system.
For example, optical system can be made up of optical beam-splitter and optical diffusion sheet, single beam iraser that infrared light generator sends
After optical beam-splitter, multi beam iraser can be become, then incide can after optical diffusion sheet for multi beam iraser
With the multiple stripe-shaped beams of generation or multiple discrete light spots, (the specific structure of texture fragment has with the optical property of optical diffusion sheet
Close).Again for example, optical system can also be declined lens arra, optical mask or other types of grating using such as holography,
Thus, it is possible to produce the infrared beam with other different textures.
In actual applications, except the three-dimensional information of monitoring space, we also need to the coloured image in acquisition monitoring space
Information, so as to transfer when needing video it is for reference and retrieval.Therefore, in above-mentioned each embodiment
For depth data supervising device, device can also include visual light imaging device.
