Three-dimensional photographing process based on laser probe array and device utilizing same

The invention discloses a three-dimensional photographing process based on a laser probe array and a device utilizing the same, and belongs to the field of three-dimensional photographing and measuring. Thousands of laser probes are projected to preset space positions according to the digital optical phase conjugation principle, reflection of the laser probes on surfaces of articles is monitored by a general two-dimensional camera, and then three-dimensional coordinate measurement is realized. Meanwhile, since the laser probe array is combined with a pair of three-dimensional cameras, more three-dimensional coordinates can be acquired by means of three-dimensional reconstruction, and accurate and compact three-dimensional coordinate measurement for large sites can be realized. Accordingly, three-dimensional matching treatment accuracy of three-dimensional images in the three-dimensional reconstruction process can be improved, matching treatment time is shortened, images picked up by the three-dimensional cameras can be compensated at the post stage, error in focal length and installation of the two cameras is eliminated, and requirements for the previous stage installation and synchronization of the focal length in the actual photographing process of the three-dimensional cameras are lowered. The three-dimensional photographing process based on the laser probe array and the device utilizing the same are applicable to fields of three-dimensional films, robots, intelligent driving, quick detection for obstacles, automatic measurement for industrial parts, and the like.

Character string matching method and system

ActiveCN105141583AImprove matching efficiencyReduce the "missing match" rate problemTransmissionMatch treatmentTheoretical computer science
The invention discloses a character string matching method and system. The character string matching method comprises the steps of decomposing a matched character string into data blocks in a preset number; matching each data block with a pattern string quickly until all the mutually matched character strings are found or a stop condition is met; and carrying out matching treatment for joints of the data blocks. The big character string is firstly decomposed into a plurality of relatively small character blocks for parallel analytic treatment before the matching of the character string and the pattern string, so that the matching efficiency of the character string can be improved greatly. When matching is carried out at the interior of each small character string, good suffix of a BM algorithm is kept unchanged, and an improved QS algorithm is combined to quickly match the character string at the same time, so that the characters as many as possible are skipped, the matching number of times is reduced, the overmatching phenomenon in the matching process is decreased and the algorithm efficiency is improved. As hashing treatment is carried out for the joints of the data blocks, the missed matching phenomenon is prevented efficiently, and the problem of missed matching rate of the character string is reduced.

An automobile voice control method, system and device based on a cloud end and a plurality of command words

The invention discloses an automobile voice control method, system and device based on a cloud end and a plurality of command words. The method comprises the following steps: carrying out voice recognition on a voice command to obtain a text message after voice recognition; through the cloud end, carrying out semantic analysis on the obtained text message, and carrying out matching to generate structured data comprising one or more command words according to a command word database stored in the cloud end; and executing a corresponding control command according to the generated structured data. The system comprises an interface module, a cloud end processing module and a vehicle-mounted master control module. The device comprises a storage device and a processor. The method can analyze theplurality of command words in the user voice command simultaneously, thereby improving execution efficiency; and since the user voice command is converted into the text message first, and then, the text message is subjected to semantic analysis, compared with a mode of carrying out matching treatment on the user voice command directly, the mode is high in matching accuracy and better in interaction. The method can be widely applied to the voice control field.

Image segmentation processing method based on area matching optimization K-means clustering algorithm

The invention relates to an image segmentation processing method based on an area matching optimization K-means clustering algorithm, comprising steps of firstly extracting vehicle feature points of front and back frame images, and then comparing an area overlapping situation of front and back frame vehicles, extracting positions of the feature points in an area overlapping region and the positions of the rest feature points, respectively calculating a mean value of the two groups of the feature points as two types of initial clustering central points to be segmented, and then implementing K-mean segmentation, correcting a classification situation of the feature points in the area overlapping region according to an output clustering result, and meanwhile, judging whether the clustered vehicles are reasonable or not; and if not, re-clustering the clustering result and recounting clustering centres, ending clustering segmentation until the reasonable vehicles are found, and then feeding back a tracking result. The method is on the basis of area matching optimization, and adopts fixed clustering numbers to implement the segmentation; and vehicle targets obtained by the K-mean segmentation do not need the next round of matching treatment, thereby a processing speed is accelerated, and time is saved.
