Title: Method and device for controlling steering of unmanned carrier and its image pickup device
Inventor: NOZAKI KOHEI
IPC: G05D1/02
Filed: 1985-12-14
Abstract: PURPOSE:To attain the stable, accurate and fast drive of an unmanned carrier by using an image pickup device decides a line having the width as a gentle curve to process the images at the remote side for steering control and then an image pickup device which decides said line as a sharp curve to pick up the images given at the front of the carrier respectively. CONSTITUTION:Both an area 4a close to an unmanned carrier 1 and a far area 4b set front of the carrier 1 are picked up at a time by a CCD camera 3. Then the steering control is given to the carrier 1 based on the data on the images in the area 4b after deciding that a drive line 6 exists at the image in the area 4b when a line having the width is regarded as a gentle curve. If it is confirmed that the line 6 does not exist at the images in the area 4b, it is decided that the line 6 has a large curve at the front side. Then the steering control is carried out based on the data on the images in the area 4a where the line 6 is completely picked up. Thus it is possible to catch accurately a driving route of the carrier 1 despite a sudden change of the line 6. This secures the stable, accurate and fast drive of the carrier 1.

Abstract: PURPOSE:To prevent the deterioration of position measurement even under the environment where received level is largely fluctuated by calculating an estimated error from 15 error quantity, intended deterioration coefficient, and the error component resulted from SIN. CONSTITUTION:A receiving antenna 1 traps the signal radio wave from a satellite, and a receiving part 2 conducts amplification of signal, frequency conversion, and inverse diffusion of spectrum. An orbit data demodulating part 3 inputting it measures the received level resulted from the S/N of a receiver together with demodulation of orbit data, and a pseudo distance measuring part 4 measures the pseudo distance to the receiver. On the basis of the orbit data and pseudo distance, a distance measurement arithmetic part 5 arithmetically operates the absolute position of the receiver and outputs it as data. At this time, the estimated error is calculated by use of the received level resulted from the S/N and the intended deterioration coefficient SVACC contained in the data, and outputted together with the distance measurement data as data. Thus, the error factor according to the S/N is set to the variable in the estimated error calculation whereby the more realistic estimated error can be calculated.
