Abstract
This disclosure provides an image processing device, which includes an actual trail image memory for storing an actual trail data group indicating absolute changes in position of a target object detected by echo signals obtained corresponding to detection signals transmitted while changing an azimuth direction of the transmission, and a moving target object determination processing module for determining whether the target object detected with the detection signals is a moving target object based on the actual trail data group.
Claims8
An image processing device, comprising:
- an actual trail image memory for storing an actual trail data group indicating absolute changes in position of a target object detected by echo signals obtained corresponding to detection signals transmitted while changing an azimuth direction of the transmission;
- a relative trail image memory for storing a relative trail data group indicating relative changes in position of the target object with respect to a transmission origin location of the detection signals;
- and
- a moving target object determination processing module for determining whether the target object detected with the detection signals is a moving target object based on the actual trail data group;
- wherein a relative trail of the target object is displayed along with the target object, the displayed relative trail being based on the relative trail data group;
- and
- wherein the target object determined to be the moving target object by the moving target object determination processing module is displayed so as to be distinguished from another target object with a relative trail substantially similar to that of the moving target object.
A method of processing an image, comprising:
- obtaining echo signals corresponding to detection signals transmitted while changing an azimuth direction of the transmission;
- storing absolute changes in position of a target object detected by the echo signals as an actual trail data group;
- storing relative changes in position of the target object detected by the echo signals with respect to a transmission origin location of the detection signals as a relative trail data group;
- determining whether the target object detected with the detection signals is moving based on the actual trail data group;
- and
- displaying a relative trail of the target object along with the target object based on the relative trail data group, where displaying includes distinguishing a target object determined to be a moving target object from another target object having a substantially similar relative trail.
A computer-readable medium having embodied thereon an image processing program for causing a computer to execute processing, the processing comprising:
- obtaining echo signals corresponding to detection signals transmitted while changing an azimuth direction of the transmission;
- storing absolute changes in position of a target object detected by the echo signals in a memory as an actual trail data group;
- storing relative changes in position of the target object detected by the echo signals with respect to a transmission origin location of the detection signals as a relative trail data group;
- determining whether the target object detected with the detection signals is a moving target object based on the actual trail data group stored in the memory;
- and
- displaying a relative trail of the target object along with the target object based on the relative trail data group, where displaying includes distinguishing a target object determined to be a moving target object from another target object having a substantially similar relative trail.
