Embodiment 1

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

[0060] Step 101: Obtain first data, where the first data characterizes vector features of a first point on a first image.

[0061] In practical applications, the vector feature is the intensity mapped to the first point in the first image under the condition that the first image is in different angle filters. In this embodiment of the application, for the convenience of calculation, the angles can be selected respectively In the filter of 0 degree, 30 degree, 60 degree, 90 degree, 120 degree and 150 degree, the intensity a of the first point in the first image is respectively mapped 1 、a 2 、a 3 、a 4 、a 5 、a 6 to form the first data.

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

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 configured to obtain first data, the first data representing the vector feature of the first point on the first image;

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

[0135] The third data acquisition unit 203 is used to perform fixed-point processing on the second data to obtain third data. The fixed-point processing is to determine the decimal places N that need to be retained when the second data is converted into a binary number, and then The first data is multiplied by 2 to the Nth power to obtain undetermined data, and the integer part in the undetermined data is determined to be the second data, ...

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 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 converted into corresponding vector images at first, and then the vector features in the two vector images are respectively extracted, and then the vector features in the two vector graphics are The vector features are converted into standard vectors for comparison, and the correlation of the vector features in the two vector images is judged by the comparison results. If the correlation is less than the predetermined threshold, it means that the two images do not match, and the judgment of the two images can be exited in advance. Whether it is a consistent process, if the correlation exceeds the predetermined threshold, it means that the image edges of the two images are similar, and yo...
