Unmanned aerial vehicles (UAVs) may facilitate the generation of a virtual reconstruction model of a vehicle collision. UAVs may collect data (including images) related to the vehicle collision, such as with the insured's permission, which may be received by an external computing device associated with the insurer and utilized to perform a photogrammetric analysis of the images to determine vehicle impact points, the road layout at the scene of the collision, the speeds and directions of vehicles, etc. This data may be used to generate a virtual reconstruction model of the vehicle collision. An insurer may use the virtual reconstruction model to perform various insurance-related tasks, such as allocating fault to drivers or autonomous vehicles involved in the vehicle collision, and adjustment of insurance pricing based upon the fault allocation. As a result, innocent drivers or vehicles may not be unfairly penalized for vehicle collisions not their fault.

The invention provides a bone registration method, a bone registration system, a bone registration control device and a trackable element. The bone registration method comprises the following steps: acquiring mark point information obtained by performing corresponding operation on the tail end of the trackable element through the bone surface when a switch of the trackable element meets a corresponding set condition; and performing bone surface virtual reconstruction according to the acquired mark point information in combination with pre-acquired bone image data. Thus, based on the control ofthe switch of the trackable element, the tail end of the trackable element is correspondingly operated on the bone surface, so the virtual reconstruction of the bone surface can be realized; the accurate registration of a physical space coordinate system and an image space coordinate system of a patient is realized; the registration work can be completed by only one operator; the precision is high, and the operation is convenient; the registration efficiency can be significantly improved; and the operation experience of an operator is good.

The invention provides an electronic transformer calibrator traceability method and system. The method comprises the following steps: a digital multimeter collects analog signals and converts the analog signals into a digital message; an upper computer carries out virtual reconstruction on the digital messages and then carries out error information superposition to form a reconstructed message; a message controller carries out timing control according to the reconstructed message; a tested electronic transformer calibrator collects the analog signals and the reconstructed message sent by the message controller and generates error information; and a comparison is made between the error information generated by the tested electronic transformer calibrator and the error information superposed by the upper computer to obtain test errors. The sample data of the digital multimeter is subjected to virtual reconstruction to enable the output digital message to be same with the message output by an actual electronic transformer merging unit, and by comparing the error information generated by the tested electronic transformer calibrator and the error information superposed by the upper computer, the test errorsof the tested electronic transformer calibrator is obtained; and therefore, full traceability work is finished.
