The embodiment of the invention discloses a tracking method and a related product. The tracking method comprises the steps: acquiring a first tracking object set of a preset detection area and a firstdetection image of the preset detection area, wherein the first tracking object set comprises at least one tracking object and tracking information of each tracking object in the at least one tracking object; and for the at least one tracking object in the first tracking object set, executing an image search operation and a position update operation according to the first detection image to obtain an updated first tracking object set. Therefore, through the embodiment of the invention, multiple tracking targets can be tracked quickly and accurately, and the real-time requirement during tracking is met.

The invention discloses a visual tracking method, a visual tracking device, an UAV(unmanned aerial vehicle) and a terminal device. The method comprises the following steps: obtaining image data of a designated area comprising a tracked object at present and operating parameters of a tracking object; based on the obtained image data of the designated area comprising the tracked object at present, obtaining possible tracked objects in the designated area and generating a tracked object library to select the tracked object; when judging that the tracking object is in relative motion with the selected tracked object, establishing a motion estimation model of the tracked object based on image features of the tracked object in the image data; and based on the motion estimation model, predicatingthe position of the tracked object in the image data of the designated area at the next moment and image features to control the tracking object.

The invention relates to a solar tracking oriented one-dimensional driving two-dimensional output robot mechanism. The invention provides the solar tracking oriented one-dimensional driving two-dimensional output robot mechanism which comprises a bracket, a solar component mounting plate, a cam, a motor, a first rotating shaft and a one-way coupler, wherein the motor is arranged on the bracket; the motor is connected with the cam through the one-way coupler; the motor is connected with the first rotating shaft; one end of the solar component mounting plate is hinged with the first rotating shaft; the other end of the solar component mounting plate is in contact with and butt-jointed with the cam; and the motor is connected with the solar component mounting plate through the first rotatingshaft and is used for driving the solar component mounting plate to rotate around the edge of the cam. The solar tracking oriented one-dimensional driving two-dimensional output robot mechanism has the beneficial effects that: one motor input is converted into two rotating shaft outputs, the solar motion is tracked and a sunlight receiving surface of a solar component is vertical to the sunlight under a working state, so that the total volume of absorbed energy is increased, the cost is lower and the reliability is higher.

The embodiment of the invention discloses an information transmission tracking method. The method comprises steps: based on first address information acquired by user equipment, first unique identification code information for characterizing a transmission identification code of the first information is acquired, wherein the first information is the information acquired by the user equipment via the acquired address information; and according to the first unique identification code information, first group user information formed by other user equipment except the user equipment corresponding to the first information is acquired, and an information transmission trajectory based on the first information is acquired. The embodiment of the invention also discloses an information transmission tracking device.

The purpose of this application is to provide a method and device for determining the business execution link in the distributed system, by creating a workflow instance corresponding to the business to be executed in the distributed system; during the execution of the workflow instance Record the corresponding execution log; determine the execution link of the business according to the execution log, and realize the tracking of the distributed system link, so as to count the end-to-end calls of the distributed system based on the execution link of each business relationship, in order to achieve the purpose of tracking the distributed system links, and to determine the execution link of the business based on the workflow-related identification information and call nesting relationship information in the execution log, so as to analyze the execution link based on the business The execution path of the distributed system is obtained, and the end-to-end call relationship in the distributed system is counted.
