The present invention discloses a catheter for mapping and / or ablating a region of the heart, comprises a catheter body with an intermediate section that is connected to a tip assembly by a highly flexible preshaped section. The highly flexible section presets the tip assembly at an off axis and / or off plane angles from the intermediate section, to provide the following: a) The intermediate section when deflected approximates the generally convex region of the cavo tricuspid isthmus and the preset angle of the flexible section is off axis in the same plane and same direction as deflection of the intermediate section to enable the tip assembly to contact the cavo tricuspid isthmus for ablation and / or mapping. b) The intermediate section when deflected approximates the generally concave region of the VA / RV / LA / LV and the preset angle in the same plane and opposite direction of deflection enables the tip assembly to contact the walls of the cavity for ablation and / or mapping. c) The intermediate section when deflected approximates the generally convex region of the His area and the preset off plane angle of the flexible section enable the tip assembly to contact the Bundle of His region. A high bending modulus of the flexible section enables the flexible section to absorb displacement force applied to the tip assembly, such as when the tip assembly encounters uneven tissue surface, without displacing the intermediate section. The flexible section prevents excessive force from being applied to the tip assembly, reducing the risk of any of the following: a) mechanical perforation, b) steam pop, c) burying the tip assembly in the myocardium resulting in high temperatures, low energy delivery, thrombus formation and char formation.

The invention discloses a control system and a control method for the cooperative surveying and mapping of an unmanned ship and an unmanned aerial vehicle. The control system comprises an unmanned ship cooperative surveying and mapping device in the unmanned ship and an unmanned aerial vehicle cooperative surveying and mapping device in the unmanned aerial vehicle which performs mutual communication cooperative surveying and mapping. The automatic surveying and mapping of shoal sea areas with many islands and reefs are realized; the surveying and mapping task of a sea area which cannot be reached by a large surveying and mapping ship can be completed with high efficiency and low cost, meanwhile, the submarine topography can be surveyed and mapped, the surveying and mapping of an upper portion of an island reef can be achieved, and the surveying and mapping task of a target sea area is achieved more completely. The invention belongs to the technical field of unmanned ship and unmanned aerial vehicle cooperative application.

The present application provides a position information determination method, comprising: determining a target object to be detected by means of a distance measuring device (S101); acquiring an imaging range of the target object on the image acquisition device (S102); acquiring distance information between the imaging center of the image acquisition device and the imaging range (S103); and determining position information of the target object according to the imaging range and the distance information (S104). The accuracy of determining the position information of the target object is improved. The invention also provides a position information determination device and a storage medium.

The invention discloses a surveying and mapping aircraft which comprises an aircraft body, a plurality of sets of wing arms are installed on the outer wall of the aircraft body, rotating fan blades driven by a motor are installed on the multiple sets of wing arms, protection rings are arranged on the peripheries of the multiple sets of rotating fan blades, and the multiple sets of protection rings are fixedly connected with the multiple sets of wing arms; a rotary holder is installed at the bottom of the aircraft body, a surveying and mapping camera is installed at the lower end of the rotary holder, and a height-adjustable supporting piece is installed on the aircraft body and penetrates through the aircraft body. According to the surveying and mapping aircraft, the surveying and mapping aircraft is provided with the adjustable supporting piece, the height of the lower end of the supporting rod can be changed, so that the surveying and mapping sight line of a surveying and mapping camera cannot be blocked, and surveying and mapping are facilitated; the output shaft of the rotating motor is provided with a circular ring with two groups of sliding rods; the output shaft of the rotating motor 7 can be prevented from being screwed out of the threaded sleeve.

The invention discloses a marine engineering water area surveying and mapping device, which comprises a measuring box and a surveying instrument. A scale for indicating the water level is fixedly connected to the front side wall of the measuring box, and first floating plates are fixedly connected to both sides of the measuring box. , the first floating plate is provided with a winding device for winding the guide rope; the bottom of the measurement box is fixedly connected with a vertically arranged guide rail, and the bottom of the surveying instrument is fixedly connected with a mobile seat. The present invention can ensure the stability of the measuring box and reduce the input of manpower through the cooperation among the measuring box, the surveying instrument, the scale, the guide rope, the winding device, the guide rail, the moving seat and the driving device, and the driving device can work easily. Lift or lower the surveying instrument from the measurement box to realize the automatic storage of the surveying instrument and provide convenience for the surveying and mapping of marine engineering.

The invention relates to a prism adjustment seat for optical surveying and mapping, which comprises: a fixed plate, and a guard plate fixed around the circumference of the fixed plate, characterized in that, the fixed plate is provided with three a first fixing hole, and a second fixing hole is arranged on the fixing plate in the triangle formed by the connecting lines of the three fixing holes; when the three first fixing holes on the fixing plate are respectively provided with a prism lens, At this time, the second fixing hole cannot be provided with a prism lens; when one second fixing hole on the fixing plate is provided with a prism lens, at this time, the three first fixing holes cannot be provided with a prism lens. Three first fixing holes and one second fixing hole are set, so that three prism lenses can be used for reflection work at the same time, and it can also be switched to only one prism lens for work, and the reflection conditions of surveying and mapping work are more flexible it is good.

The invention discloses an interior design surveying and mapping device, comprising a surveying and mapping main body, a support rod and a support device. The surveying and mapping body is mounted on a fixed plate, the fixed plate is fixedly connected with the support rod, the support rod is provided with a support device near the lower end, and the support rod is close to the lower end. The part is provided with a first sliding cavity. The lower side of the first sliding cavity is a second sliding cavity, a third sliding cavity and a fourth sliding cavity. The support device includes a push-pull rod, a support rod, a first slider, a first push rod, The second slide block, the second push rod, the third slide block and the third push rod, push the first slide block to push the push-pull rod to open the support rod, and adjust the height of the support rod by pushing the second slide block to make the device It can be placed on a horizontal plane or on a step and can be kept parallel, which is convenient for surveying and mapping subjects to measure.
