According to the technical scheme, the mobile phone acquires a speed oscillogram acquired by intelligent wearable equipment, and divides the speed oscillogram into w oscillogram intervals according to a set time region; the mobile phone samples each oscillogram interval according to a set sampling rate to obtain a plurality of speed values, and the plurality of speed values form an input vector according to a sampling sequence; the mobile phone determines a first identity of a target object, extracts a weight vector corresponding to the first identity, performs vector multiplication on the input vector and the weight vector to obtain a product result, and determines whether the oscillogram region belongs to a running state according to the product result; and combining all the waveform map regions belonging to the running state to obtain a combined waveform map, and counting the steps of the combined waveform map to obtain the number of running steps. According to the technical scheme, whether the oscillogram interval is in the running state or not can be determined during step counting, and then the interval which does not belong to the running state is removed, so that the identification precision is improved, and the user experience is improved.
The determining, by the mobile phone, the first identity of the target object may specifically include:
e1, acquiring a target face image of a target image of the target object;
e2, verifying the target face image;
e3, when the target face image passes the verification, determining that the target object is a first identity corresponding to a preset face module.
In the specific implementation, a preset face template can be stored in the electronic device in advance, the original image of the target object can be obtained through the camera, and then the first identity of the target object can be determined when the target face image is successfully matched with the preset face template by the electronic device, otherwise, the first identity of the target object is not determined, so that the identity of the target object can be identified, whether the first identity is a reserved patient or not can be judged, and the fact that other people start telemedicine is avoided.
Further, in a possible example, in the step S202, the extracting the stored data for verification may include the following steps:
e21, performing region segmentation on the target face image to obtain a target face region, wherein the target face region is a region image only of a face;

The electronic device may obtain a region segmentation of the target face image to obtain a target face region, where the target face region may be a region that does not include a background but only includes a face, that is, a region image of only a face. And then, can carry out binarization processing to target face region, obtain two quantification face image, so, can reduce the image complexity, divide two quantification face image into a plurality of regions, the area size of each region is equal, and is greater than preset area value. Further, feature point extraction may be performed on the binarized face image to obtain a plurality of feature points, and an algorithm of the feature extraction may be at least one of the following: scale Invariant Feature Transform (SIFT), SURF, pyramid, harris corner detection, etc., without limitation.

Further, when the target quality evaluation value is smaller than the preset quality evaluation value, the terminal may perform image enhancement processing on the target face image, match the target face image after the image enhancement processing with the preset face template, and determine that the target face image passes verification if the matching value between the target face image and the preset face template is larger than a preset threshold value, otherwise, determine that the target face image fails verification.
The step of performing vector multiplication on the input vector and the weight vector to obtain a product result may specifically include:
the mobile phone determines the weight vector as an alpha vector, the maximum value of the number of the same element values in the alpha vector is arranged, the element value beta (beta is a non-zero value) corresponding to the maximum value in the alpha vector is arranged to the head position (such as the first element position) of the alpha' vector, generating a bitmap (bitmap, in the bitmap, if the element value in the α -th vector is β, the bitmap is 1, otherwise, the bitmap is 0, for example, 10,8,9,10 is the α -th vector, and β =10, the bitmap = 1001), arranging the bitmap to another position of the head of the α 'vector (for example, a second element position, if the position is insufficient, the second and third element positions are determined to be another position), arranging the element in the α -th vector, which is the same as the element value β, to a subsequent position of the α' vector (except for the head position) after deleting the element, and storing the α 'vectors in ascending order of the line values of the α' vectors; the mobile phone extracts an alpha ' vector and a row vector corresponding to the input data and the alpha ' vector, adds element values of which bitmap is 1 in the row vector, multiplies the element values with the head position to obtain a product result, multiplies elements at the residual position of the row vector and corresponding element values at the residual position of the alpha ' vector to obtain a product result, adds all the product results to obtain a vector product result, determines that the oscillogram interval belongs to a running state if the product result is greater than a running threshold value, and otherwise, determines that the oscillogram interval does not belong to the running state.
The technical scheme reduces the data volume of data storage and the number of multiplication operations, and takes an actual example as an example, for the element values in the vector, 32 bits are occupied, if 64 elements exist in the alpha-th vector, 64 bits are needed by a bitmap, and each bit corresponds to whether each of the 64 elements is beta or not, so that the data volume stored is small as long as more than 3 element values are the same in the 64 elements, and in actual application, the probability that the vectors in the same column in weight data are the same is higher, so that the storage volume can be reduced, the data storage overhead is reduced, the data processing efficiency is improved, and the user experience is improved.
The implementation method for determining the first identity of the target object may also be implemented by AI recognition, and the method may specifically include:
the mobile phone establishes input data according to the picture of the target object, inputs the input data into the face recognition model to execute n layers of convolution operation to obtain an nth layer of convolution operation result, inputs the nth layer of convolution operation result into the full-connection layer to execute full-connection operation to obtain a full-connection calculation result, calculates a difference value between the full-connection calculation result and a preset face template result, and if the difference value is smaller than a difference value threshold value, the UE determines that the identity of the target object is the identity of the preset face template.
In an optional scheme, the inputting the input data into the face recognition model to perform n-th layer of convolution operation to obtain an nth layer of convolution operation result specifically may include:
the mobile phone may be provided with an individual AI chip, where the AI chip is used to perform the authentication of the target object, and the AI chip includes: the AI chip acquires a matrix size CI CH of input data, if the convolution kernel size in n layers of convolution operation is 3X 3 convolution kernels, the distribution calculation processing circuit divides the CI CH into CI/x data blocks (assuming that CI is an integer of x) according to the CI direction, distributes the CI/x data blocks to the x calculation processing circuits in sequence, the x calculation processing circuits respectively execute the ith layer of convolution operation on the 1 data block received and distributed and the ith layer of convolution kernel to obtain the ith convolution result (namely, the ith convolution result is obtained by sequentially combining x result matrixes (CI/x-2) (CH-2) of the x calculation processing circuits), and sends the result of 2 columns at the edge of the ith convolution result (the result of the adjacent columns is 2 columns obtained by calculation of different calculation processing circuits) to the distribution processing circuit, the x calculation processing circuits execute convolution operation on the ith layer of convolution result and the (i + 1) th layer of convolution kernel to obtain an (i + 1) th layer of convolution result, the (i + 1) th layer of convolution result is sent to the distribution calculation circuit, the distribution calculation processing circuit executes the ith layer of convolution operation on the (CI/x-1) th combined data block and the ith layer of convolution kernel to obtain an ith combined result, the ith combined result and the edge 2 column result of the ith convolution result are spliced (the ith combined result is inserted into the middle of the edge 2 column according to the mathematical rule of the convolution operation) to obtain an (i + 1) th combined data block, the (i + 1) th combined data block and the (i + 1) th convolution kernel execute convolution operation to obtain an (i + 1) th combined result, the (i + 1) th combined result is inserted into the (i + 1) th layer of convolution result between the edge column (the results of the adjacent columns are calculated by different calculation processing circuits) to obtain an (i + 1) th layer of convolution result, and the AI chip executes the operation of the residual convolution layer (convolution kernel after the layer i + 1) according to the convolution result of the layer (i + 1) to obtain the convolution operation result of the layer n. The combined data block may be a 4 × CI matrix composed of 4 columns of data between 2 adjacent data blocks, for example, a 4 × CH matrix composed of the last 2 columns of the 1 st data block (the data block allocated to the 1 st calculation processing circuit) and the first 2 columns of data of the 2 nd data block (the data block allocated to the 2 nd calculation processing circuit).
The calculation of the above-mentioned remaining convolutional layers can also be referred to the calculation of the i-th layer and the (i + 1) -th layer, where i is an integer not less than 1 and not more than n, where n is the total number of convolutional layers of the AI model, i is the layer number of the convolutional layer, CI is the column value of the matrix, and CH is the row value of the matrix.
Referring to fig. 2c (each square in fig. 2c represents an element value), fig. 2c is a schematic diagram of a matrix size CI × CH of input data and a schematic diagram of a 3 × 3 convolution kernel. For a conventional distribution-computation structure, such as a master-slave structure, in the computation, each layer of convolution operation needs to return all the i-th layer of convolution results to the master structure, and then the i-th layer of convolution results is distributed to the slave structure to perform the i + 1-th layer of computation, but after the i-th layer of convolution operation is performed in the technical scheme of the application, only the results of adjacent 2 columns are sent to the distribution processing circuit, and the i + 1-th layer of convolution results is performed after the residual part of convolution results, so that the residual part of convolution results does not need to be returned to the distribution computation processing circuit, and the distribution computation processing circuit does not perform the convolution operation again, so that the distribution computation processing circuit can also reduce the distribution overhead, and further perform the convolution operation on the data of the combined part of data blocks to achieve the purpose of complete convolution operation.
