First Claim
1. A vehicle peripheral-area display apparatus comprising:
- an image pick-up unit for picking up images of a peripheral area of a vehicle;
a positional information detecting unit for detecting the own vehicle position of said vehicle as positional information;
a data storage unit for storing picture data of the peripheral area of the vehicle, the picture data is picked up by said image pick-up unit, and also storing said positional information of the vehicle;
a picture composite unit for reading out picture data corresponding to the positional information detected by said positional information detecting unit from said data storage unit, and for combining said read picture data with such picture data indicative of a shape of said vehicle; and
a display control unit for causing the picture data combined in said picture composite unit to be displayed on a display unit.

Abstract
0 A vehicle peripheral-area display apparatus comprising: a camera (11) for picking up images of a peripheral area of a vehicle (2); an integration processing unit (21) for detecting the vehicle'"'"'s own position as positional information via a vehicle sensor (12); a memory (15) for storing present picture data as to the peripheral area of the vehicle picked up by the camera (11), and also for storing positional information as to the picked up images of peripheral area of the vehicle; a picture composite unit (25) for reading past picture data corresponding to the positional information from the memory (15) by way of a memory control unit (24), and for combining own vehicle shape data “x” with this past picture data; and a display control unit (26) for displaying the picture data combined by this picture composite process unit (25) on a monitor display unit (16). As a result, this vehicle peripheral-area display apparatus of the present invention can display not only the road surface of the lower portion of the vehicle body of this vehicle, but also the past peripheral-area.

3. A vehicle peripheral-area display apparatus as claimed in claim 1, wherein said positional information detecting unit includes:
-
a steering amount detecting unit for detecting a steering amount equivalent to a steering angle of said vehicle;
a travel distance detecting unit for detecting a travel amount equivalent to a travel distance of said vehicle; and
an integration processing unit for calculating the own vehicle position of said vehicle as positional information by performing an integration process operation with respect to both the steering amount detected by said steering amount detecting unit and the travel amount detected by said travel distance detecting unit.

-
4. A vehicle peripheral-area display apparatus as claimed in claim 3 further comprising:
-
a picture data comparing unit for comparing present picture data of the peripheral area of the vehicle picked up by said image pick-up unit with the picture data which is stored in said data storage unit and corresponds to the positional information of said vehicle; and
a correction coefficient calculating unit for calculating a correction coefficient for the integration process operation executed by said integration processing unit so as to correct the present positional information based upon an error of a portion where the present picture data is overlapped with the past picture data by said picture data comparing unit.
-
-
5. A vehicle peripheral-area display apparatus as claimed in claim 1,
wherein said picture composite unit produces three-dimensional picture data based upon the picture data corresponding to the present position information and picture data corresponding to such positional information located adjacent to said present positional information, and also combines said three-dimensional picture data with the picture data of the vehicle. -
6. A vehicle peripheral-area display apparatus as claimed in claim 1 further comprising:
-
a picture map producing unit for producing a picture map based upon a plurality of positional information and also past picture data corresponding to the respective positional information, which are stored in said data storage unit, wherein said display control unit displays said picture map produced by said picture map producing unit on said display unit.
-
-
7. A vehicle peripheral-area display apparatus as claimed in claim 1, wherein said image pick-up unit includes:
-
a backward image pick-up unit for image pick-up a backward scene of said vehicle;
a forward image pick-up unit for image pick-up a forward scene of said vehicle;
a travel direction detecting unit for detecting a travel direction of said vehicle; and
a control unit for executing the image pick-up operation only by said forward image pick-up unit when said travel direction detecting unit detects a forward travel of said vehicle, and also for executing the image pick-up operation only by said backward image pick-up unit when said travel direction detecting unit detects a backward travel of said vehicle.
