Embodiment 1

[0064] The embodiment of the present invention provides a mobile phone camera camera tracking device, see figure 1 , the system consists of:

[0065] The camera module 10, embedded in the back of the mobile phone, is used to receive the transmitted light of the scene and convert the intensity signal of the transmitted light into an electrical signal and then into a digital image signal;

[0066] The image processing module 20, connected to the camera module 10, is used to receive and process the digital image signal, generate a display signal, and perform calculations based on the display signal to obtain the spatial angle of the scene relative to the camera module 10, generate and send the angle information to the control module;

[0067] The display module 30 is connected to the image processing module 20, and is used to display the scenery on the mobile phone screen 60 according to the display signal;

[0068] The handheld pan-tilt module 40 is connected to the image proc...

Embodiment 2

[0092] The present invention provides a camera tracking method for a mobile phone camera, which is suitable for the mobile phone camera camera tracking device shown in Embodiment 1, see Figure 6 , the method includes:

[0093] S1. Receive the transmitted light of the scene and convert the intensity signal of the transmitted light into an electrical signal and then convert it into a digital image signal;

[0094] S2. Receive and process digital image signals to generate display signals;

[0095] S3. Displaying the scene on the mobile phone screen 60 according to the display signal;

Abstract

The invention provides a mobile phone camera photography tracking device and method. The device comprises a camera module for receiving transmission light of scenery, converting a transmission light strong / weak signal into an electric signal, and then converting the electric signal into a digital image signal; an image processing module for receiving and processing the digital image signal and generating a display signal; a display module for displaying the scenery on a mobile phone screen according to the display signal; a handheld holder module for regulating a posture of the camera module according to the angle information. The space positioning of the target is realized by shooting a picture through a mobile phone, the mobile phone is convenient to carry, and the positioning process issimple; an space angle of the target relative to the mobile phone camera is determined through simple numerical calculation, and the positioning is accurate; a tracking function on the target is realized through the handheld holder, and the mobile phone camera photography tracking device is suitable for various complex and unknown environments.

Description

technical field [0001] The invention relates to the application field of electronic technology, in particular to a mobile phone camera camera tracking device and method. Background technique [0002] Target positioning technology is divided into two-dimensional and three-dimensional positioning technology. In intelligent monitoring, with the increase of the complexity of the monitoring scene, target tracking based on two-dimensional images can no longer meet the requirements of reliable tracking. The most reliable feature in target matching and tracking is its three-dimensional space coordinates. In computer vision, how to obtain the coordinates of corresponding spatial points in the actual coordinate system from image points is called the three-dimensional reconstruction problem, which is the core problem in three-dimensional computer vision. [0003] At present, the methods of using images to locate the target in space mainly include: at least two or more camera equipmen...
