Embodiment 1

[0059] Please refer to figure 1 , Embodiment 1 of the present application provides an information processing method applied to an electronic device, and the method includes:

[0060] Step 101: Obtain first data, the first data representing the vector feature of the first point on the first image.

[0061] In practical applications, the vector feature is the intensity mapped by the first point in the first image when the first image is in different angle filters. In the embodiment of this application, for the convenience of calculation, the angles can be selected respectively. It is the intensity a mapped from the first point in the first image under the filters of 0 degree, 30 degree, 60 degree, 90 degree, 120 degree and 150 degree. 1 , A 2 , A 3 , A 4 , A 5 , A 6 To compose the first data.

[0062] It can be seen from the above definition that the first data can be N intensity values ​​corresponding to the N different angle filters mapped out by the points in the image under the con...

Embodiment 2

[0132] Please refer to figure 2 , Embodiment 2 of the present application provides an electronic device, and the electronic device includes:

[0133] The first data obtaining unit 201 is used to obtain first data, the first data representing the vector feature of the first point on the first image;

[0134] The second data obtaining unit 202 is configured to perform a normalization operation on the first data to obtain second data, and the normalization operation is an operation to obtain a standard vector of the first point;

[0135] The third data acquisition unit 203 is configured to perform fixed-point processing on the second data to obtain third data, and the fixed-point processing is to determine the decimal place N that needs to be retained when the second data is converted into a binary number, and then Multiplying the first data by the N-th power of 2 to obtain undetermined data, and determining that the integer part of the undetermined data is the second data, and N is a ...

Abstract

The invention discloses an information processing method and electronic equipment, and the method comprises the steps: obtaining first data representing the vector features of a first point on a first image, carrying out the fixed-point processing of the first data, and obtaining second data; carrying out the normalization of the second data, and obtaining third data for representing a standard vector of the first point; judging whether the first image and a second image are matched or not based on the third data and fourth data, wherein the fourth data is a standard vector for representing a second point, corresponding to the first point, on the second image. Therefore, the electronic equipment can achieve the matching judgment process of the images through the standard vector and fixed point number calculation, and solves problems that the electronic equipment is heavy in operation burden and slow in calculation speed in a matching process of the images through employing floating data. The method is higher in calculation speed than the prior art.

Description

Technical field [0001] The present invention relates to the field of electronic technology, in particular to an information processing method and electronic equipment. Background technique [0002] In the existing technology for judging whether two images are consistent, generally the two images are first converted into corresponding vector images, and then the vector features in the two vector images are extracted respectively, and then the two vector images are The vector features are converted into standard vectors for comparison, and the correlation between the vector features in the two vector images is determined from the comparison results. If the correlation is less than the predetermined threshold, the two images do not match, and you can exit early to determine the two images Whether it is a consistent process. If the correlation degree exceeds a predetermined threshold, it means that the image edges of the two images are similar. You can continue to determine the corre...
