4results about How to "Reduce positioning costs" patented technology

The invention discloses a data processing method, a data processing device, a computer readable storage medium, electronic equipment and a computer program product, and the method comprises the steps: obtaining memory usage data and event response data of a target application, and determining the correlation degree of an interaction event and memory leak according to the memory usage data and the event response data, and positioning an interaction event causing the memory leak. Thus, a developer can check the function point corresponding to the interaction event based on the positioned interaction event so as to check whether the function point can cause memory leakage, and compared with a mode that the developer checks all the function points one by one, assistance can be provided for the check work of the developer, so that the check efficiency is improved.

The invention provides a positioning method, device and equipment of environment Internet of Things equipment. The method comprises the following steps: sending a first message to environmental Internet of Things equipment, wherein the first message carries an identifier of the environmental Internet of Things equipment; receiving a second message sent by the environment Internet of Things equipment, and obtaining positioning related information; and generating a third message according to the positioning related information, the third message carrying the position information of the environmental Internet of Things device, or the third message carrying the positioning related information. Thus, the reading device obtains the positioning related information according to the received second message sent by the environment Internet of Things device, and generates a third message according to the positioning related information, and the third message comprises the position of the environment Internet of Things device determined by the reading device or the information related to the position. According to the method, the environment Internet of Things equipment does not need to perform measurement, and the reading equipment can obtain the positioning related information according to the message fed back by the environment Internet of Things equipment, so that the complexity and the positioning cost of the environment Internet of Things equipment can be reduced.

The application provides a multi-pose pedestrian indoor positioning method fused with visual information, comprising the following steps: S1. establishing a mobile phone holding pose recognition model; S2. determining the mobile phone holding pose by using the mobile phone holding pose recognition model, and then compensating the heading angle of the PDR algorithm; S3. introducing a judgment algorithm to remove the meaningless compensation heading angle in the pose conversion process and redetermine the compensation heading angle; S4. based on the compensation heading angle redetermined in step S3, constructing a multi-pose PDR and outputting a positioning result; and S5. designing a PDR error correction model based on visual position recognition, eliminating cumulative errors and further improving the positioning accuracy of the multi-pose PDR. The multi-pose pedestrian indoor positioning method fused with visual information can adapt to the pose transformation of pedestrians and can correct the cumulative errors in real time, can enhance the precision and robustness of the pedestrian indoor positioning in the case of reducing the burden of the positioning system on the pedestrians and compressing the positioning cost to the greatest extent.
