Problems solved by technology

However, due to the material and printing method of the crawling mat, it is difficult to use a computer for image recognition, the accuracy is not high, and it cannot be matched or quickly matched, which affects the use of augmented reality technology.
The main problems of the existing crawling mats are as follows: 1. The crawling mat has a plastic film and high light reflection, which leads to inaccurate identification

Embodiment 1

[0025] see figure 1 , Embodiment 1 provides an augmented reality method for removing highlights and repeated textures, the method comprising the following steps:

[0026] S101: Obtain a real-time image to obtain an original image.

[0027] S102: Segregate the highlight area in the original image obtained in step S101 by calculating the outline and position of the highlight area, and perform noise reduction and filtering processing on the highlight area that can preserve the identification features. Specifically, this step can be based on the statistical rules of color, and the highlight can be removed by using the characteristic of local smoothness of the maximum diffuse reflection chroma. This step does not necessarily preserve the original image exactly, but it can preserve enough recognizable image features.

[0028] S103: Determine whether the image after highlight removal in step S102 contains repeated texture features, if there are repeated texture features, perform st...

Embodiment 2

[0034] Embodiment 2 provides an augmented reality method for removing highlights and repetitive textures, the method comprising the following steps:

[0035] S201: Run an augmented reality program on a mobile terminal or field device.

[0036] S202: Invoke the camera to scan the crawling mat and objects on it to obtain real-time images.

[0037] S203: Determine whether the current processing device has a GPU, if so, send the original image obtained in step S202 to the GPU for processing, and execute steps S204-207; if there is no GPU, send the original image obtained in step S202 to the CPU for processing, Execute steps S204-207. That is, in order to improve the processing speed, the image is sent to the GPU for processing first.

[0038]S204: Calculate the gray value of the original image obtained in step S202, determine the highlight area (the average gray value is continuously distributed between 220 and 245) according to the gray value, and use the canny operator of Open...

Embodiment 3

[0050] see Figure 6 , Embodiment 3 provides an augmented reality system for removing highlights and repeated textures, the system comprising:

[0051] The crawling mat is a common crawling mat on which various patterns are printed.

[0052] Camera 1: used to obtain real-time images.

[0053] Image processing module 2: used to obtain the original image obtained by camera 1, separate the highlight area in the original image, and perform noise reduction and filtering processing on the highlight area that can retain the recognition features; determine whether the image contains repeated texture features after highlight removal , if there are repeated texture features, then determine the position of the texture point according to the texture feature value, perform smoothing filtering on the texture point, and send the image after texture removal to the augmented reality module 3; if there is no repeated texture feature, send the image after highlight removal to Augmented Reality...

Abstract

The invention discloses an augmented reality method for the elimination of highlight and repeated texture and a creep pad application, and belongs to the technical field of augmented reality. The method comprises the steps: obtaining a real-time image; separating a highlight region in an original image, and carrying out the noise reduction and filtering processing, which can keep the recognition features, of the highlight region; judging whether the image comprise the repeated texture features or not after the highlight elimination; determining the position of a texture point according to the texture features if there are the repeated texture features; carrying out the smooth filtering of the texture point; and carrying out the augmented reality processing of the image after texture elimination. The creep pad application comprises a creep pad, a camera, an image processing module, an augmented reality module, and a mobile terminal. The method is high in matching speed, is small in number of errors, and is low in resolution. Moreover, the creep pad application can improve the playability and education performances.

Description

technical field [0001] The invention belongs to the field of augmented reality technology, and in particular relates to an augmented reality method for removing highlights and repeated textures and an application of a crawling mat, in particular to an augmented reality method for a crawling mat. Background technique [0002] Some parents take care of their babies very carefully. Even when they reach the age when their babies can crawl, they always hold or push their babies because they are afraid of the dirt on the ground, the baby catching cold on the ground, or being caught on the ground, etc. conditions, thereby depriving the baby of the opportunity to crawl. If the baby learns to walk without experiencing crawling, although it will not have a serious impact on his life, it may cause problems such as inattention and poor coordination after the baby goes to school. A kind of crawling mat product is provided on the market to solve the above problems. [0003] The crawling...
