摘要:
In an object, for example, a pilotless flying object detection system, an omnidirectional camera as a first camera images a monitoring area. A microphone array acquires audio of the monitoring area. A monitoring apparatus uses the audio data acquired by the microphone array to detect a pilotless flying object which appears in the monitoring area. A signal processor in the monitoring apparatus superimposes a discrimination mark, obtained by converting the pilotless flying object into visual information, on image data of the monitoring area when displaying the image data of the monitoring area captured by the omnidirectional camera on a monitor.
摘要:
Relative to the microphone array system, toward a location corresponding to the position specified by the image of the predetermined range in which the camera device is the image imaging to form a sound collection directivity of the sound, and sound collection audio data with high accuracy. The directivity control system 10, the signal processing unit 33, in response to designation of an arbitrary position from the user in the video data displayed on the screen of the display device 36, into the screen from the installation position of the microphone array system 2 It picked up toward the sound position corresponding to the position of the specified video data Te (8MAh, 8MAv) to derive. The signal processing section 33 forms a sound collection directivity of the sound data to the derived sound collection direction (8MAh, 8MAv).
摘要:
Provided a sound velocity correction device including an environmental parameter obtainer that acquires a measured value of a surrounding environmental parameter of a sound collector that collects a sound emitted from a sound source; and a sound velocity corrector that corrects a sound velocity of the sound which is used to form directivity in a directing direction toward the sound source from the sound collector, using the measured value of the surrounding environmental parameter of the sound collector which is acquired by the environmental parameter obtainer.
摘要:
A recorder (45) receives designation of a video image that a user wants to be reproduced. Upon receiving designation of one or more designated positions where sound is to be amplified as indicated by the user in a screen of a display (63), on which the video image is displayed, via an operation unit (55) while the video image from the recorder (45) is being reproduced or paused, a signal processing unit (50) performs sound data amplification processing, that is, data on sound with respect to directions from a microphone array (20) to the positions corresponding to the designated positions is amplified using sound data recorded in the recorder (45). A reproduction unit (60) reproduces the amplified sound data and the video image in a synchronized manner.
