Pixel data generating device, image display device, radar apparatus, and method of generating pixel data

Abstract

The invention provides a pixel data generating device, an image display device, a radar apparatus, and a method of generating pixel data. In a pixel data generating device provided to image display devices, such as radar apparatuses, draw interpolation data can be generated by taking the circumferential direction in consideration without leaving any pixel omitted portions. The pixel data generating device includes an echo intensity calculating module and and an interpolating content generating module. The echo intensity calculating module converts the the pixel data on the sweep line S1 and the pixel data on the sweep line S2 into the pixel data in the XY rectangular coordinate system, respectively. The interpolating content generating module generates the pixel data of the target pixel located between the observing pixel located on the interpolation target line parallel to the X-axis or the Y-axis of the XY rectangular coordinate system and the corresponding pixel located on the same interpolation symmetrical line. The pixel data of the target pixel is generated based on the pixel data on the sweep line S1 and the pixel data on the sweep line S2. .

Description

technical field [0001] The present invention mainly relates to a pixel data generation device and method, an image display device, and a radar device, which generate pixel data corresponding to the distance from the above-mentioned emission source as XY right angles based on the echo signal of the detection signal emitted from the emission source. The pixel data of the coordinate system. Background technique [0002] A signal processing device such as a radar device displays on a monitor an image in which an object is plotted based on the position of the device (antenna) so that the user can intuitively grasp the positional relationship with the object. Here, on the above-mentioned display, pixels are generally arranged in a grid (matrix). Therefore, when an object or the like is drawn on an image, the positions of the pixels are handled on the XY rectangular coordinate system. Therefore, in the above-mentioned signal processing device, in order to display on a display, gen...

Problems solved by technology

In this regard, in the method of interpolating pixels one by one in the X-axis direction or Y-axis direction, the direction in which pixels are interpolated (X-axis direction or Y-axis direction) is different from the direction in which pixels have continuity (circumferential direction). , so it is difficult to generate the interpolated data in parallel with the rendering of the interpolated data
