3D camera with lens group capable of synchronous automatic expansion and contraction

Abstract

The invention discloses a 3D camera with a lens group capable of synchronous automatic expansion and contraction. The 3D camera includes a lens group formed by two or more lenses; a motor used for driving the lenses to move so as to carry out focusing; and a controller used for sending out control signals so as to control the motor to operate, wherein the number of the motor is one and the motor is capable of driving the two or more lenses to move synchronously under the control of the controller so as to carry out focusing. In the 3D camera, the lens group is controlled to synchronously and automatically expand and contract through one motor so that synchronous automatic focusing of the lens group is realized and thus time spent on manual focusing of a common lens group can be reduced and focusing precision is improved and the picture effect is more true to life.

Description

technical field [0001] The invention relates to a camera, in particular to a 3D camera with two or more lenses. [0002] Background technique [0003] At present, the application of 3D cameras has been very common, and its stereoscopic images can bring people good visual enjoyment, and are very popular. A 3D device such as a general 3D camera usually has more than two lenses, and each lens is matched with a sensor, and each sensor synthesizes a 3D image by focusing data collected by each sensor. However, the lenses of the current 3D cameras are independent of each other, and the sensors of each lens are also independent of each other. If the focus data collected by the independent sensors cannot be synchronized, the effect of the synthesized 3D image will be relatively poor. To solve the above problems, the current method is to manually or individually adjust the focus of the lens. This solution is difficult to achieve a uniform focus between the lenses, and it takes a lon...

Problems solved by technology

However, the lenses of the current 3D cameras are independent of each other, and the sensors of each lens are also independent of each other. If the focus data collected by independent sensors cannot be synchronized, the effect of the synthesized 3D image will be relatively poor.

To solve the above problems, the current method is to manually or individually adjust the focus of the lens. This solution is difficult to achieve a uniform focus between the lenses, and it takes a long time and the accuracy is very low.
