<p>PURPOSE:To improve identification accuracy to an unspecific body which generates a sound and vibration by performing primary estimation based upon frequency analytic data on the sound, vibration, etc., and secondary estimation based upon image data. CONSTITUTION:When a specified sound collection microphone 2 detects a sound, a sound analyzer 3 takes a frequency analysis of its signal and supplies the result to a data collator 6. The collator 6 estimates the body by using only the sound. Similarly, when a specified vibration sensor 4 detects vibration, a vibration analyzer takes a frequency analysis of its signal and supplies the result to the collator 6. The collator 6 estimates the body by using only the vibration and collates composite data obtained by both the analyzers to estimate the unspecified body. Then when the video signal of a CCD camera 7 is supplied, an image multi-valuing processor 8 performs processing and supplies the result to a data collator 9 and an image feature extraction processor 10. The collator 10 estimate the body by using only its image and supplies data obtained by the collator 6 when the body is in an estimated body zone, and the processor 10 performs secondary image processing.</p> |
