Embodiment Construction

[0077] In order to more accurately determine the spatial position of the target object relative to the image acquisition device based on the collected images, in the implementation process of the present invention, the inventor proceeded from the projection law between the real object and the image, and carried out derivation work. A relational expression containing difficult-to-determined parameters is converted into a relational expression composed of relatively easy-to-determined parameters, thereby simplifying the calculation and operation work required to determine the spatial position of the object relative to the image acquisition device, and effectively improving The accuracy of the determined location description information.

[0078] The technical solutions provided by the embodiments of the present invention will be described in detail below in conjunction with specific embodiments and drawings.

[0079] see figure 2 , figure 2 is a flow chart of a method for de...

Abstract

The embodiment of the invention provides a method for determining locations and a device thereof. The method comprises the following steps: collecting an image with target object imagery; acquiring area description information used for describing the occupied area of the imagery in the image; and determining a spatial location by using the area description information and pre-determined relation parameters which can reflect the correlative relation between the area description information and the spatial location of the target object. The technical scheme of the embodiment of the invention has the advantages that the spatial location can be determined more accurately; and the unique spatial location of the target object relative to the image collecting device can further be determined.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method and device for determining a position. Background technique [0002] The continuous development of image digital processing technology promotes the digitization process of image acquisition equipment and its wide application in many fields. For example, in some cases, it is desirable to know the spatial position of the photographed target relative to the image acquisition device based on image processing technology, so as to perform other operations based on the known spatial position, such as, in the simulation application, use the position description of the above spatial position Perform relevant calculations based on information, such as predicting or judging whether the person in front of the image acquisition device will encounter obstacles to test the flexibility of the person's limbs; another example is to provide the position description information of ...
