Description
Technical field
The present invention relates to electronic monitoring technical field, particularly a kind of directional surveillance system.
Background technology
In the fields such as aviation, navigation, excursion, direct of travel is a very important parameter, but owing to surrounding lacks significant object, driver is difficult to judge the direct of travel of oneself by observing extraneous things.Therefore by instrument, direct of travel must be measured, and by measurement feedback to driver, in order to driver understands the direct of travel of self and makes corresponding adjustment.
But, during driving, driver needs the problem paid close attention to a lot, as a example by offroad vehicle driver, driver needs to observe at any time surface conditions, barrier situation and car body situation etc., these information all can increase the visual cognition load of driver, the visual load easily making driver reaches capacity, but correspondingly, driver's utilization rate of audition load and haptic load in driving procedure is relatively low, therefore, if able to utilize audition and sense of touch that the direct of travel of driver is reminded, it is beneficial to alleviate the visual load of driver, driver is avoided to cause danger due to eyes overstrain.
