Guidance and assessment device

Abstract

A guidance and assessment device is mounted on an unmanned vehicle and can communicate with a handheld electronic device. A target measurement unit measures a target object and its surrounding environment as the unmanned vehicle moves through the environment to obtain a spatial signal related to the target object. A signal processing unit calculates the relative position of the target object in three-dimensional space based on the spatial signal provided by the target measurement unit. A control unit controls a light-emitting unit to project a guide beam to a specific location in the environment based on the relative position provided by the signal processing unit. A wireless communication unit is electrically connected to the control unit and wirelessly communicates with the handheld electronic device to transmit the relative position provided by the control unit to the handheld electronic device. An assessment unit generates an assessment result based on the relative position provided by the signal processing unit and transmits the assessment result to the handheld electronic device via the wireless communication unit.
