[0007] Another example is Taiwan's new patent application No. 95217697 "computer pointer operating device". The pointer operating device proposed in this case requires the user to wear a ring on the fingertip as a basis for location tracking. In other words, the patent can only track location Objects worn with rings

Embodiment Construction

[0023] The technical means and functions used by the present invention to achieve the purpose will be described below with reference to the accompanying drawings, and the embodiments listed in the following drawings are only for auxiliary explanation, so as to facilitate the examiner's understanding, but the technical means in this case are not Limited to the figures listed.

[0024] see figure 1 The calculation flowchart of the method for calculating the position of unstructured objects in continuous images provided by the present invention is shown as follows:

[0025] Step 101: The location tracking procedure starts.

[0026] Step 102: Initialize the template of the target object that the user intends to locate and track. see figure 2 As shown, it shows that an image of the user 30 is captured by an image capture device 20 and displayed on a screen 40, and a specific area 41 is set on the screen 40, and the specific area 41 is used for setting initialization The target...

Abstract

The invention relates to a method for calculating an unstructured object position in a continuous image, which comprises: firstly, a line sample board of a target object is built, and the position of a characteristic part of the line sample board is analyzed; secondly, a continuous image of the target object is picked, and the candidate position of the characteristic part of the current image is calculated by using the luminance fluctuation around the characteristic part in the continuous image; thirdly, the difference degree of the image around the candidate position in the continuous image and the similarity of the image around the candidate position and the line sample board of the target object are calculated; and the position of the characteristic part of the target object in the image is calculated by using the calculated difference degree and the similarity of the line sample board of the target object.

Description

technical field [0001] The invention relates to a method for calculating the position of an unstructured object in continuous images, especially a method for calculating the search space of the next time point by using a tracking algorithm after initializing a target object template, and using images of motion and edges The feature information is used to calculate the similarity with the template, so as to track the method of locating the position of the target object. Background technique [0002] In the human-computer interaction interface, it is more difficult to identify the user's activities purely by image processing, compared with wearable and contact sensing tools, and the memory and processing time required for image processing are very large. To achieve The effect of real-time response is relatively difficult; in addition to the specific object you want to track and locate, it often contains many interference factors such as background, noise, and light changes. Th...
