Image data computing apparatus |
摘要 |
An image data computing apparatus for computing three-dimensional image data on the basis of detection data obtained by employing a two-dimensional sensor array including a plurality of ultrasonic sensors. The apparatus includes a line memory for storing the detection data obtained on the basis of output signals of the plurality of sensors, a storage unit for storing as a table therein transfer time period data determined by the relations between distances from a transmission unit to the respective sensors through respective points to be measured and transfer velocities of the ultrasonic wave in the corresponding paths, and a computation unit for reading the detection data stored in the line memory in accordance with the transfer time period data and computing image data at the respective points to be measured on the basis of the read detection data.
