Abstract

An exemplary method for planning a route in an electronic map uses a control computer. A first updated electronic map is produced. The first updated electronic map records a number of moving objects actually at each of locations represented on the electronic map, and a current position of a user of a handheld device. The moving objects are those detected by image capturing devices actually at the physical locations that are represented on the electronic map. Then a start position and an end position input on the first updated electronic map are received from the handheld device, and an optimized route from the start position to the end position is determined. Then a second updated electronic map is produced by recording the optimized route on the first updated electronic map, and the second updated electronic map is sent to the handheld device.

Claims

1. A computer-implemented method for planning an optimized route on an electronic map using a handheld device comprising a processor, the method comprising:

receiving a route planning function instruction selected by a user of the handheld device;

receiving a first updated electronic map from a control computer, the first updated electronic map recording a number of moving objects actually at the physical location of each of a plurality of monitored areas that are represented on the electronic map;

receiving a start position and an end position input on the first updated electronic map by the user;

sending the start position and the end position to the control computer; and

receiving a second updated electronic map from the control computer, and displaying the second updated electronic map on a display device of the handheld device, the second updated electronic map recording an optimized route from the start position to the end position.

2. The method according to claim 1, wherein the optimized route is a planned route which comprises the lowest number of moving objects from the start position to the end position.

3. A computer-implemented method for planning an optimized route on an electronic map using a control computer comprising a processor, the method comprising:

recording positions of a plurality of image capturing devices actually at the physical locations of each of a plurality of monitored areas that are represented on the electronic map;

obtaining an image of the monitored area captured by each of the plurality of image capturing devices periodically, detecting a number of moving objects in the obtained image, and producing a first updated electronic map, the first updated electronic map recording the number of moving objects at each monitored area;

receiving from a handheld device a start position and an end position for the first updated electronic map;

determining an optimized route from the start position to the end position, and producing a second updated electronic map by recording the optimized route on the first updated electronic map; and

sending the second updated electronic map to the handheld device.

4. The method according to claim 3, wherein the optimized route is a planned route which comprises the lowest number of moving objects from the start position to the end position.

5. The method according to claim 3, wherein the moving objects are detected using at least one of a vehicle license plate recognition method and a pedestrian detection method.

6. A control computer, comprising:

a storage device;

at least one processor; and

one or more modules that are stored in the storage device and executed by the at least one processor, the one or more modules comprising;

a setting module that sets positions on an electronic map of a plurality of image capturing devices at a plurality of monitored areas, the image capturing devices being actually at the physical locations of the monitored areas that are represented on the electronic map;

a moving object detection module that obtains an image of the monitored area captured by each of the image capturing devices periodically, detects a number of moving objects in the obtained image, and produces a first updated electronic map, the first updated electronic map recording the number of moving objects at each monitored area;

a receiving module that receives coordinates of a current position of a user from a handheld device, and produces a second updated electronic map by recording the coordinates of the current position of the user on the first updated electronic map;

a sending module that sends the second updated electronic map to the handheld device; and

a route planning module;

wherein the receiving module further receives from the handheld device an end position input on the second updated electronic map;

the route planning module determines an optimized route from the current position of the user to the end position, and produces a third updated electronic map by recording the optimized route on the second updated electronic map; and

the sending module further sends the third updated electronic map to the handheld device.

7. The control computer according to claim 6, wherein the optimized route is a planned route which comprises the lowest number of moving objects from the current position of the user to the end position.

8. The control computer according to claim 6, wherein the moving objects are detected using at least one of a vehicle license plate recognition method and a pedestrian detection method.
