摘要： A semantic-based method and apparatus for retrieving a perspective image, an electronic device and a computer-readable storage medium are provided. An method includes obtaining a perspective image for a space containing an inspected object therein. A semantic division on the perspective image is performed using a first method, to obtain a plurality of semantic region units. A feature extraction network is constructed using a second method. Based on the perspective image and each of the plurality of semantic region units, a feature of each semantic region unit is extracted using the feature extraction network. Based on the feature of each semantic region unit, an image most similar to the semantic region unit is retrieved from an image feature database, to assist in determining an inspected object in the semantic region unit.

摘要： A fork-arm lift tractor includes a vehicle body, a supporting plate disposed above the vehicle body, a lifting device for driving the supporting plate to be lifted, a front and rear fork-arm assemblies, a front and rear fork-arm drive assemblies. The front fork-arm assembly includes two front fork-arms rotatably disposed at the supporting plate. The rear fork-arm assembly includes two rear fork-arms rotatably disposed at the supporting plate, and the front and rear fork-arms may be deployed or retracted from both sides of the supporting plate. The front fork-arm driving assembly includes a front transmission part, and a front power device disposed at the supporting plate and may drive the front transmission part to move horizontally linearly so as to rotate the two front fork-arms. The rear fork-arm driving assembly has almost the same structure of the front fork-arm driving assembly and is used to rotate the two rear fork-arms.

摘要： A vehicle inspection system is described. The vehicle inspection system comprises: an inspection device, for performing an inspection on a vehicle to be inspected; a carrier platform, for carrying the vehicle to be inspected; and an unmanned controlled travelling device for moving the carrier platform to pass through a scanning area of the inspection device, so as to perform the inspection on the vehicle to be inspected. In the present disclosure, the vehicle to be inspected is carried by the carrier platform, and the unmanned controlled travelling device is used to move the carrier platform to pass through the scanning area of the inspection device, so that the vehicle to be inspected can be subject to inspection smoothly. There is no driver required to drive through the scanning area in this process, thus avoiding exposure of a driver to a threat of radiation.
