Problems solved by technology

If you use a product with less than 3 cameras, due to the limited viewing angle of the camera itself, you cannot collect the real-time situation of the moving object in real time and give real-time feedback to the motor, so there will be slow response when tracking the object; if you use a multi-camera product , not only due to the increase in production costs due to multiple cameras, but also the need to process the images collected by the cameras through better processing chips, which further leads to an increase in production costs

Embodiment 1

[0061] like Figure 1-5 As shown, an object tracking device includes a lens 1, a reflective mirror and a movable stand, the stand is connected to a shooting device (such as a mobile phone, a tablet, etc.), and the lens 1 and the reflective mirror are fixed on the stand.

[0062] Lens 1 can be an ordinary lens, a fisheye lens, a wide-angle lens, etc. For example, Canon’s model is EF 50mmf / 1.8STM, and the closest focusing distance of this product is 35cm; / 2.0 product, the closest focusing distance of this product is 22cm. The number of lens 1 is at least one, and a single wide-angle lens is used in this embodiment, and the FOV is 60 degrees.

[0063] Reflecting mirror surface can adopt conical mirror surface 2 or polygonal pyramid mirror surface (such as triangular pyramid mirror surface 3, hexagonal pyramid mirror surface 4 etc.) or rotational symmetry optical aspheric surface mirror surface 5 (such as parabolic mirror surface, elliptic mirror surface, hyperbolic surface mirr...

Abstract

The invention discloses an object tracking device. A lens and a reflector are arranged on a seat stand; by means of the reflection effect of the reflector, images are formed in the lens by surrounding scenes, the camera shooting equipment moves and completes alignment tracking through the movable base table, visual angle limitation does not exist, and if multiple lenses are adopted, the multiple lenses do not need to work at the same time, and the requirement for hardware models and parameters is lowered. The invention discloses an object tracking method. The reflection effect of the reflector is utilized to make the peripheral scene form an image sequence in the lens; images in an image sequence are compared; through juding the threshold value, the image of the to-be-tracked object is acquired, the positioning of the tracked object is completed through coordinate calculation, the motion instruction is sent to the seat stand, the camera of the camera shooting equipment is aligned with the tracked object, and calculation and superposition of data of a plurality of lenses are not needed due to reflector matching and lenses.

Description

technical field [0001] The invention belongs to the field of automatic object tracking equipment, in particular to an object tracking device and method. Background technique [0002] At present, conventional tracking devices generally install mobile phones or tablets on the gimbal, and realize the automatic tracking of the gimbal through the use of software combined with the front camera of the mobile phone or tablet, or combined with active tracking technology. Among them, automatic tracking uses dynamic recognition technology when tracking. When the object is not facing the camera of the mobile phone, or the resolution of the built-in camera of the mobile phone is not good enough, the tracking effect is poor; , because the camera itself will have a certain specification of the viewing angle limit, that is, a fixed FOV (field of view), if the object leaves the camera's viewing angle, the gimbal will not work normally; because the conventional product uses a camera combined ...
