Problems solved by technology

In the existing technology, it is all realized by additional equipment, such as providing an LED light source, and for the external light source, it is necessary to consider the coordination and cooperation with the TOF equipment to provide a suitable active light source. This process undoubtedly makes The use of TOF equipment is more cumbersome, and the technical requirements are relatively high
[0007] In addition, in the development trend of existing smart devices, compatibility, intercommunication, and data sharing between different devices are extremely important aspects, but existing TOF devices usually do not have such convenient functions

Embodiment Construction

[0047]The following description serves to disclose the present invention to enable those skilled in the art to carry out the present invention. The preferred embodiments described below are only examples, and those skilled in the art can devise other obvious variations. The basic principles of the present invention defined in the following description can be applied to other embodiments, variations, improvements, equivalents and other technical solutions without departing from the spirit and scope of the present invention.

[0048] Such as Figure 1 to Figure 5 Shown is the TOF circuit module according to the first preferred embodiment of the present invention. The TOF circuit module calculates the time-of-flight of the light signal by comparing the phase shift, and further measures the depth of the target based on the three-dimensional time-of-flight of the light signal. information, so as to obtain the image information of the target object with parameters such as depth, di...

Abstract

The invention relates to a TOF (Time-Of-Flight) circuit module and application of the same. The TOF circuit module includes a light source unit and a reflected light unit, wherein the light source unit includes a driving circuit which drives a lighting module to generate the modulated light; and the reflected light unit is used for receiving a reflection signal when the modulated light passes through a target object so as to obtain the distance information from the target object to the circuit module.

Description

technical field [0001] The present invention relates to the technical field of TOF, and further relates to a TOF circuit module and its application. Background technique [0002] With the development of optical measurement and computer vision, optical three-dimensional measurement technology has gradually matured, and has gradually appeared in the fields of gesture control, 3D modeling, automotive radar and robot vision systems, and has become a hot spot in the current measurement field. The application process is inseparable from the 3D camera module. [0003] In recent years, the direction of the camera module has been developed towards the realization of various new functional applications such as 3D imaging, distance measurement, and somatosensory interaction, and TOF (Time-Of-Flight) technology is a more prominent performance among many 3D optical measurement technologies. of a technique. The basic principle of TOF technology is: the light emitted by the active light ...
