DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the field observation and measurement of academic research, and the observation and measurement of an image of a target object, the measurement data recording, and the voice recording of a target object at the time of field observation and measurement in a company. A novel method and apparatus for recording and reproducing in synchronization with environmental data such as signal data and geomagnetic signal data,
This is particularly effective when data is collected while moving over a wide area in a short time. Such records are, for example, various fields such as meteorological observations such as temperature, humidity, wind speed, and weather; terrain observations such as landslides; road congestion observations; animal ecology observations; and plant overgrowth observations. It can be used for continuous observation of.

[0002]

2. Description of the Related Art Conventionally, observation data has been collected by separately using a measuring device and a video / audio recording device such as a camera, a video camera, a tape recorder, and the like, and environmental data such as time and place are recorded in a notebook. I wrote it down.

[0003]

Conventionally, observation has been performed as described above, and therefore, for example, the following problems have occurred. It is difficult to analyze sudden changes in measurement data and their causes. When performing continuous measurement, data may fluctuate rapidly, and it is almost impossible to analyze the cause. The positional relationship between the image data at the observation point and the measurement data is not clear. 2. Description of the Related Art In general outdoor observation and outdoor observation, optical photography is performed. However, it is difficult for the image information to have time synchronization with the measured data. Furthermore, in the case of observing a large number of objects in a wide range while moving an object of similar state or form, the conventional image information is better than recording the date, time information, and positional information in a notebook. Did not. The temporal relationship between image recording and measurement recording is not clear. In the case of vegetation spectroscopy observed in the field, the measurement data is the position of the sun and the state of the sun's rays (for example, moving clouds change the energy of light rays),
Because it is constantly changing due to weather conditions (for example, the wind is constantly affecting the observation target). Instantaneous various comments at the time of observation are recorded on a notebook or an audio tape recorder, but it is difficult to obtain time synchronization at the time of analysis.
