The invention relates to a method and a device for measuring image inclination angle of a business card, which belong to the technical field of OCR. The method extracts the edge image of a business card image at first, searches the peripheral frame line of a business card in the edge image, judges if the image is inclined according to the inclination degree of the peripheral frame line, judges word editing direction thereof for the inclined picture, projects along the word editing direction and calculates the inclination angle of the image by projection characteristic. Judging the inclinationof the image by collecting the peripheral frame line of the image, the invention can divide the images into an inclination type and an aclinal type quickly and process the two types respectively. Theinvention quickly judges the word editing direction by comparing the characteristics of projection histograms in the horizontal direction and the vertical direction. The determination of the word editing direction is greatly useful for calculating the inclination angle by projecting and analyzing the layout of the business card image.

The invention discloses a liftably-slantwise conveying mechanism. The liftably-slantwise conveying mechanism comprises a support (10) provided with a drive device, a liftable lifting stand (20) installed on the support (10), and a rolling wheel rack (30) installed on the liftable lifting stand (20), wherein the rolling wheel rack (30) is connected with the liftable lifting stand (20) by virtue of a hinge (41) and a location screw (42); the hinge (41) and the location screw (42) are located close to the both ends below the rolling wheel rack (30) respectively; the location screw (42) is installed on the liftable lifting stand (20). The liftably-slantwise conveying mechanism further comprises a stop block (50) installed below one end of the rolling wheel rack (30), and the stop block (50) is located below the location screw (42). By virtue of the technical scheme, the problem of slantwise location for a component during a vertical conveying process is solved on the premise of realizing vertical conveying for the component.

The invention discloses a slope-finding plastering device for floor drain periphery concrete or mortar and a using method thereof. The slope-finding plastering device comprises a vertical rod, one ormore inclined rods, one or more mortar smearing linkage rods and inclined rod installing bushes, and a floor drain abutting-against disc sleeves the bottom end of the vertical rod, and can rotate relative to the vertical rod; one end of each mortar smearing linkage rod is rotatably installed at the lower end of the vertical rod; the inclined rod installing bushes sleeve the vertical rod and can slide in the length direction of the vertical rod and be positioned; the upper end and the lower end of each inclined rod are rotatably installed on the corresponding inclined rod installing bush and the corresponding mortar smearing linkage rod respectively. Before plastering, the inclination angle of the mortar smearing linkage rods is first adjusted to a designed slope, and when slope-finding plastering is performed, the vertical rod is rotated to drive the mortar smearing linkage rods to rotate to realize one-time forming. With the slope-finding plastering device for the floor drain periphery concrete or mortar and the using method thereof, plastering of a slope-finding layer of a floor drain periphery can be performed well at a time, the slope is precise, and operation is convenient.

The application provides a license plate correction method and device, the method comprising: obtaining the character connected domain of the license plate image, extracting the upper edge points and lower layer edge points of the character connected domain; obtaining the character corner points of the license plate image, extracting Upper-level character corner points and lower-level character corner points; determine the first point set according to the upper-level edge points and upper-level character corner points, and determine the second point set according to the lower-level edge points and lower-level character corner points; according to the first point set and the second point set Determine the tilt angle of the license plate image, and use the tilt angle to correct the license plate image. This application determines the inclination angle according to the first point set and the second point set obtained by the upper and lower layer edge points and the upper and lower layer character corner points, and determines the inclination angle according to the upper and lower layer character corner points when there is no character connected domain, and the background interference causes the character When there are many corner points, the upper and lower layer edge points are used to limit the character corner points, so in different situations, the inclination angle can be accurately determined, thereby improving the accuracy of license plate correction.

The invention discloses an asphalt waste collection and treatment equipment for road traffic construction, which comprises an engine, a hollow structure charging box, an inner sleeve, a material delivery tray and a collection tray, the charging box is vertically arranged above the engine, And the top of the charging box is set with a stirring seat, one end of the charging box is obliquely provided with an inner sleeve, and the inner sleeve is provided with a feeding tray, and one end of the bottom of the inner sleeve is provided with a collection tray. The beneficial effect of the present invention is that: during the moving process of the equipment, the asphalt waste on the road surface is shoveled into the shovel loading bucket, and the motor on the scraper frame drives the pentagonal frame and the scraper plate to rotate through the rotating shaft. Five scraping plates rotate to scrape the asphalt waste on the road into the collection tray. On the one hand, it ensures that the equipment collects the asphalt on the road more comprehensively and thoroughly. On the other hand, it cooperates with the equipment to collect asphalt waste in a mobile manner Work, greatly improving the efficiency of the equipment for collecting asphalt waste.

The invention discloses a hoisting device with an angle display function and a hoisting method and particularly relates to a hoisting device provided with an angle display mark, a metal pointer, various clamping devices and a fine adjustment device and mounted on a cross beam of the hoisting device, as well as a use method of the hoisting device. A hoisted article is lifted to an accurate inclination angle required by a user and can be placed in the landing position without repeated adjustment, the article is protected from damage, the working efficiency is improved, and the safety of inclination hoisting operation is ensured.
