Abstract: A memory access system that includes a data sending apparatus, an optical transmission medium, and a data receiving apparatus. The data sending apparatus includes a signal generator, an optical switch, and an optical modulator. The signal generator controls the optical switch to output the optical wave of the wavelength corresponding to the target memory, and the optical wave carries an electrical signal corresponding to an access request, so that an optical signal carrying the access request is directly transmitted from the optical transmission medium to the data receiving apparatus without passing through the optical switch anymore, which avoids noise interference generated when the optical signal passes through the optical switch.

Abstract: A ground environment detection method and apparatus are disclosed, where the method includes: scanning a ground environment by using laser sounding signals having different operating wavelengths, receiving a reflected signal that is reflected back by the ground environment, determining scanning spot information of each scanning spot of the ground environment based on the reflected signal, determining space coordinate information and a laser reflection feature of each scanning spot based on each piece of scanning spot information, partitioning the ground environment into sub-regions having different laser reflection features, and determining a ground environment type of each sub-region. Lasers having different operating wavelengths are used to scan the ground, and the ground environment type is determined based on the reflection intensity of the ground environment under different wavelengths of lasers, thereby improving a perception effect of a complex ground environment, and better determining a passable road surface.
