Description

A kind of camera lens applied to TOF technology

Technical field

The utility model relates to optical lens technology field, specially a kind of camera lens applied to TOF technology.

Background technique

With the continuous development of science and technology, field applied by camera lens is also more and more, as TOF technology appears in me Sight, take pictures and also strided forward from current 2D epoch to the 3D epoch, TOF technology, i.e. sensor issue modulated near infrared light, Meet object back reflection, sensor by calculate light transmitting and reflection interval difference or phase difference, come convert be taken scenery away from From furthermore shooting, can represent in different colors the three-D profile of object in conjunction with traditional camera to generate depth information The topographic map mode of different distance shows, this is a kind of application technology of 3D scanner, and purpose is exactly to penetrate laser light Scanning element continuously transmits signal detection object, is all the plane 2D captured through X-axis and Y-axis relative to our traditional photos Image, through TOF camera lens help can allow photo be added Z-direction depth information, to obtain more three-dimensional imaging.With The development of science and technology, TOF technology will become one of the most basic technology for realizing our the following intelligent society living environments, Therefore a camera lens researched and developed to be applicable in the development of TOF technology is very necessary.

Utility model content

The problem of for background technique, the utility model provide a kind of camera lens applied to TOF technology.

To achieve the above object, the utility model provides the following technical solutions: a kind of camera lens applied to TOF technology, packet Lens barrel is included, pressing ring is provided at the Jing Kou of the lens barrel, is equipped with Lens assembly and distance member, the lens set in the lens barrel Part includes the first eyeglass, the second eyeglass and third eyeglass set gradually, and the distance member includes between the first spacer ring, second Spacer ring and third spacer ring, first spacer ring and the second spacer ring are set to first eyeglass and second eyeglass Between, anti-dazzling screen is provided between first spacer ring and second spacer ring, the third spacer ring is set to described Between second eyeglass and the third eyeglass；Optical filter is provided with outside the lens barrel, the optical filter allows the infrared light penetrated Wavelength is 830-870nm.

As the utility model a preferred technical solution, the infrared waves that the optical filter allows to penetrate are a length of 850nm。

As the utility model a preferred technical solution, first eyeglass, the second eyeglass and third eyeglass are used Be made of plastic cement material.

As the utility model a preferred technical solution, the Lens assembly and distance member arranged in co-axial alignment.

As the utility model a preferred technical solution, it is threadedly coupled at the pressing ring and the Jing Kou of the lens barrel.

Compared with prior art, the utility model has the beneficial effects that the utility model whole design is infrared by adding Film can be suitable for the application of TOF technology, and in addition whole design is simple for structure practical, small volume, have more wide city Field prospect, convenient for promoting.

Detailed description of the invention

Fig. 1 is a kind of camera lens applied to TOF technology provided by the utility model；

In figure: 1- lens barrel；2- pressing ring；The first eyeglass of 3-；The second eyeglass of 4-；5- third eyeglass；The first spacer ring of 6-；7- Two spacer rings；8- third spacer ring；9- anti-dazzling screen；10- optical filter；11- sensor.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Embodiment:

Referring to Fig. 1, the utility model provides a kind of camera lens applied to TOF technology, including lens barrel 1, the lens barrel 1 It is provided with pressing ring 2 at Jing Kou, Lens assembly and distance member are equipped in the lens barrel 1, the Lens assembly includes setting gradually The first eyeglass 3, the second eyeglass 4 and third eyeglass 5, the distance member include the first spacer ring 6, the second spacer ring 7 and Third spacer ring 8, first spacer ring 6 and the second spacer ring 7 be set to first eyeglass 3 and second eyeglass 4 it Between, anti-dazzling screen 9 is provided between first spacer ring 6 and second spacer ring 7, the third spacer ring 8 is set to institute It states between the second eyeglass 4 and the third eyeglass 5；It is provided with optical filter 10 outside the lens barrel 1, is specifically placed on camera lens and chip Between 11, the optical filter 10 allows a length of 830-870nm of infrared waves penetrated, and the utility model is allowed by optical filter 10 The a length of 835-865nm of the infrared waves of transmission (optimal is 850nm), ensure that the camera lens can use on daytime and night, fits Application for TOF technology.
