RADIO COMMUNICATION APPARATUS, RADIO COMMUNICATION METHOD, AND RADIO COMMUNICATION SYSTEM

摘要

[Problem] Provided is a radio communication apparatus that is easy to maintain. [Solution] A radio communication apparatus (10) is a P-to-P communication-purpose radio communication apparatus that is opposed, as a master or slave apparatus, to a slave or master apparatus, respectively. A radio transmitting/receiving unit (120) has a directional antenna. A storage unit (110) stores reference image data (111) and captured image data (112) obtained by an image capturing unit (150). The image capturing unit (150) has an optical axis oriented in the same direction as the radio wave direction of the directional antenna and captures an image related to a line of sight of the other opposed radio communication apparatus. An image processing unit (160) compares the reference image data (111) with the captured image data (112). A control unit (100) detects, from the comparison result, and informs that an obstacle is traveling toward the aforementioned radio wave direction.
