Description

Technical Field

[0001] This invention relates to the field of photogrammetry software testing technology, and more specifically, to a testing platform for the development of photogrammetry software. Background Technology

[0002] Photogrammetry is a branch of surveying, primarily used for mapping topographic maps at various scales and building digital terrain models, providing fundamental data for various geographic information systems (GIS) and land information systems. The two main problems that photogrammetry addresses are geometric positioning and image interpretation. Geometric positioning determines the size, shape, and spatial location of the photographed object. Its basic principle stems from the forward intersection method in surveying, which uses two known photographic stations and two known photographic ray lines to intersect and determine the three-dimensional coordinates of specific ground points constituting these two ray lines. In particular, the software program on photogrammetric equipment needs to be input into the storage chip and tested using a specialized testing platform to ensure it meets standard requirements.

[0003] In existing technologies, photogrammetry software needs to be written onto a storage chip medium and tested using specialized equipment. This process requires manual operation, makes it difficult to quickly match different models, and limits testing to one type of software for each model. This slows down the testing speed and makes it difficult to identify specific differences in test results, hindering operators from quickly reviewing the data. Summary of the Invention

[0010] In a preferred embodiment, a transparent panel is installed on the side wall of the test operation box, and the transparent panel is hinged to the test operation box. The transparent panel is made of resin material.

[0011] In a preferred embodiment, a protective frame is provided outside the display screen, the protective frame is bonded to the display screen, and a mouse stand is installed on one side of the protective frame.

[0012] In a preferred embodiment, the displacement mechanism includes a connecting collar bracket disposed on one side of the picking and positioning mechanism. A sliding positioning block is installed at the top of the connecting collar bracket. A transverse moving support frame is disposed outside the connecting collar bracket. A transverse transmission screw is threadedly connected to the inner wall of the connecting collar bracket. A transverse servo motor is installed at one end of the transverse transmission screw.

[0015] The technical effects and advantages of this invention are as follows: 1. This invention, through the layout of a multi-station testing mechanism, places four memory chip media sequentially in the first, second, third, and fourth test mounting frames. The test probe inputs the test software data into the service connector and compares it with pre-stored test software data. After the data detection memory chip media completes data matching, the comparison report generator generates a difference report and displays it on the screen. This allows for rapid matching testing of photogrammetry software at multiple stations, effectively improving the testing speed of software data, and the generated difference report is easy for operators to read and understand. 2. This invention utilizes a transverse push rod in the picking and positioning mechanism to move a support plate to one side. This movement causes a row of positioning suction cups to move to the same side. A vacuum generator creates suction in the connecting hose, causing the positioning suction cups to hold the storage chip media. This allows for the holding of different models of test software storage chip media, making it suitable for testing various types of software storage chip media. Furthermore, it reduces the risk of human error and test deviations, resulting in more accurate testing. 3. This invention utilizes the longitudinal lead screw in the displacement mechanism to drive the longitudinal helical block, causing the concave positioning slide to slide along the support frame. The transverse transmission lead screw drives the connecting collar bracket, causing the sliding positioning block to move along the transverse moving bracket frame. This facilitates transverse and longitudinal transmission, enabling rapid movement to the memory chip medium retrieval position for retrieval. Furthermore, it maintains transverse and longitudinal transmission stability during the transmission process, preventing the software memory chip medium from shaking and becoming inaccurately positioned, thus avoiding test failure and achieving higher test stability.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] As attached Figure 1-8 The test platform for the development of photogrammetry software shown includes a support base 1, a test operation box 2 installed on the top of the support base 1, a multi-station test mechanism installed on the top of the test operation box 2, a pick-and-place positioning mechanism installed on the top of the multi-station test mechanism, and a displacement mechanism installed on one side of the pick-and-place positioning mechanism. The multi-station testing mechanism includes two positioning plates 3 positioned above the test operation box 2. A first test mounting frame 4 is positioned on one side of the positioning plate 3, a second test mounting frame 5 is positioned on one side of the first test mounting frame 4, a third test mounting frame 6 is positioned on one side of the second test mounting frame 5, and a fourth test mounting frame 7 is positioned on one side of the third test mounting frame 6. Test probes 8 are provided at the bottom of the inner walls of the first test mounting frame 4, the second test mounting frame 5, the third test mounting frame 6, and the fourth test mounting frame 7. A data generation box 9 is installed on one side of the test operation box 2. An installation slot is opened on one side of the data generation box 9. A service connector 10 is installed inside the installation slot. A data storage chip medium 11 is installed on one side of the service connector 10. A control storage chip medium 12 is installed below the data storage chip medium 11. A data detection storage chip medium 13 is connected to the output end of the control storage chip medium 12.

[0027] As attached Figure 5 and Figure 6 As shown, the retrieval and positioning mechanism includes multiple positioning suction cups 16 disposed above the first test mounting frame 4. A positioning suction tube 17 is mounted on the top of each positioning suction cup 16. A collecting and stretching tube 18 is mounted on the top of each positioning suction tube 17. A connecting hose 19 is mounted on the top of each collecting and stretching tube 18. A vacuum generator 20 is mounted on one end of the connecting hose 19. Mounting plates 21 are disposed on both sides of the collecting and stretching tube 18. A positioning slide plate 22 is connected to one side of each mounting plate 21. A movable support plate 23 is mounted on one side of each positioning slide plate 22. A downward pressure rod 24 is mounted above the movable support plate 23. A downward pressure air valve is mounted on the top of the downward pressure rod 24. The cylinder 25, driven by the downward pressure cylinder 25, moves the downward pressure rod 24, causing the moving support plate 23 to move the positioning slide plate 22 downward. The mounting plate 21, driven by the positioning suction tube 17, moves the positioning suction cup 16 downward during this movement. The vacuum generator 20 generates suction force on the connecting hose 19, allowing the positioning suction cup 16 to hold the memory chip medium and place it into the first test mounting frame 4. This allows for the placement of various test memory chip media in designated positions, enabling rapid multi-station testing. The testing process is less prone to damage to the memory chip media, avoiding errors caused by human contact. The collecting tension tube 18 is preferably a corrugated pipe.

[0028] As attached Figure 5 As shown, a stabilizing collar rod 26 is provided on the other side of the mounting plate 21 near the four corners. A movable connecting cylinder 27 is sleeved on the outside of the stabilizing collar rod 26. A positioning block 28 is provided on the outside of the movable connecting cylinder 27 so that when a row of positioning suction cups 16 moves to the same side, the two stabilizing collar rods 26 slide inside the movable connecting cylinder 27. This allows for stable adjustment of the spacing between the two rows of positioning suction cups 16, thereby attracting different types of memory chip media.

[0029] Preferably, the positioning block 28 is used as a temporary positioning limit block after adjustment, and the stabilizing collar rod 26 and the movable connecting cylinder 27 are slidably connected. When the transverse cylinder 33 is driven, the stabilizing collar rod 26 can slide freely in the movable connecting cylinder 27 to achieve spacing adjustment. After adjustment, it can be temporarily fixed by the positioning block 28 or other locking parts to ensure stability during the suction process.

[0030] As attached Figure 5 As shown, a stabilizing movable plate 29 is provided outside the connection between the positioning suction tube 17 and the positioning suction cup 16. A supporting slide plate 30 is movably connected to the top of the stabilizing movable plate 29. The movable connection here is preferably a sliding connection. A push bracket plate 31 is connected to one side of the stabilizing movable plate 29. A transverse push rod 32 is connected to one side of the push bracket plate 31. A transverse cylinder 33 is installed at one end of the transverse push rod 32 so that the transverse cylinder 33 drives the transverse push rod 32 to move to one side. The push bracket plate 31 drives the movable connecting cylinder 27 to move on the supporting slide plate 30. This can provide a driving force for adjusting the size of the adjustment range, so as to be suitable for testing different types of memory chip media.

[0031] As shown in the attached diagram, a safety protection door 34 is installed above the test operation box 2 and on one side of the positioning plate 3. A three-color audible and visual alarm 35 is installed at the top of the safety protection door 34, and a control button 36 is installed on one side of the safety protection door 34. The three-color audible and visual alarm 35 is used to check whether the monitoring data is normal and to remind the operator. The safety protection door 34 can be easily opened or closed for equipment maintenance.

[0032] As attached Figure 1 As shown, a transparent panel 37 is installed on the side wall of the test operation box 2. The transparent panel 37 is connected to the test operation box 2 by a hinge. The transparent panel 37 is made of resin material so that the internal wires of the test operation box 2 can be viewed through the transparent panel 37. During daily inspections, fault points can be quickly identified to ensure safety.

[0033] As attached Figure 1 As shown, a protective frame box 38 is provided on the outside of the display screen 15. The protective frame box 38 is bonded to the display screen 15. A mouse placement table 39 is installed on one side of the protective frame box 38 so that the protective frame box 38 can support and stabilize the display screen 15, and protect the display screen 15 from damage. At the same time, the mouse placement table 39 can hold a mouse.

[0034] As attached Figure 3 and Figure 4As shown, the displacement mechanism includes a connecting collar bracket 40 disposed on one side of the picking and positioning mechanism. A sliding positioning block 41 is installed on the top of the connecting collar bracket 40. A transverse moving support frame 42 is disposed outside the connecting collar bracket 40. A transverse transmission screw 43 is threadedly connected to the inner wall of the connecting collar bracket 40. Specifically, a screw nut is disposed on the connecting collar bracket 40, and the transverse transmission screw 43 passes through and is threadedly connected to the screw nut.

[0035] A horizontal servo motor 44 is installed at one end of the horizontal transmission screw 43. Two concave positioning slide plates 45 are installed at the bottom of the horizontal moving bracket frame 42. A longitudinal screw ring block 46 is connected to one end of the concave positioning slide plate 45. A longitudinal screw 47 is set inside the longitudinal screw ring block 46. A longitudinal drive motor 48 is installed at one end of the longitudinal screw 47 so that the longitudinal screw 47 drives the longitudinal screw ring block 46 to move forward. The horizontal transmission screw 43 drives the connecting collar bracket 40 to move to one side, and the positioning suction cup 16 moves to a position perpendicular to the positioning plate 3.

[0036] As attached Figure 4 As shown, a support frame 49 is installed at the bottom of the longitudinal lead screw 47. Three installation limit blocks 50 are provided on one side of the bottom of the support frame 49. The installation limit blocks 50 are made of alloy material so that the support frame 49 can be supported and stabilized by the installation limit blocks 50, thus ensuring the stability of the support frame 49.

[0037] As attached Figure 3 and Figure 4 As shown, the sliding positioning block 41 is slidably connected to the upper position of the transverse moving bracket frame 42, and the concave positioning slide plate 45 is fixedly connected to the longitudinal screw ring block 46 under the action of the thread. The longitudinal screw ring block 46 is made of alloy material so that the sliding positioning block 41 can move on the transverse moving bracket frame 42 to maintain stability, and the longitudinal screw ring block 46 can move on the concave positioning slide plate 45 to facilitate transmission.

[0038] Working principle of the invention: When preparing for placement, the storage chip medium with the input photogrammetry software program can be placed in the positioning disk 3 inside the test operation box 2 and arranged neatly in sequence; During testing, the longitudinal drive motor 48 can be started to drive the longitudinal lead screw 47 to rotate. The longitudinal lead screw 47 drives the longitudinal screw ring block 46 to move forward under the action of the thread. The longitudinal screw ring block 46 drives the concave positioning slide plate 45 to slide along the support frame 49. The concave positioning slide plate 45 moves forward to the horizontal moving support frame 42. When the multiple positioning suction cups 16 move to the position parallel to the positioning disk 3, the horizontal transmission lead screw 43 can be started to rotate. The horizontal transmission lead screw 43 drives the connecting collar bracket 40 to move to one side under the action of the thread. The connecting collar bracket 40 drives the sliding positioning block 41 to move along the horizontal moving support frame 42. In this way, the positioning suction cup 16 can be moved to a position perpendicular to the positioning disk 3. When adjusting the suction range, the transverse cylinder 33 can be activated to move the transverse push rod 32 to one side. The transverse push rod 32 moves the push bracket plate 31 to one side, and the push bracket plate 31 moves to one side on the support slide plate 30. The stabilizing collar rod 26 can move within the movable connecting cylinder 27, thereby moving a row of positioning suction cups 16 to the same side. After the range adjustment is completed, the pressing cylinder 25 is activated. The pressing cylinder 25 moves the pressing rod 24 downward, and the pressing rod 24 moves the moving support plate 23 to move the positioning slide plate 22 downward. The positioning slide plate 22 moves the mounting plate 21 downward. The mounting plate 21 drives the positioning suction tube 17 to move downwards, and the positioning suction tube 17 drives the positioning suction cup 16 to move downwards. The positioning suction cup 16 begins to contact the storage chip medium on the positioning plate 3. The vacuum generator 20 is activated to generate suction force in the connecting hose 19, so that multiple positioning suction cups 16 can hold the storage chip medium. Then, the air is released from the connecting hose 19 by the solenoid valve, so that the positioning suction cups 16 release the storage chip medium and place it into the first test mounting frame 4. In this way, three storage chip media can be placed in the second test mounting frame 5, the third test mounting frame 6, and the fourth test mounting frame 7 in sequence. During testing, test software data is input into the service connector 10 via the test probe 8. The service connector 10 then imports the software data into the data storage chip medium 11 and compares it with the stored test software. After the imported data comparison is completed, the control storage chip medium 12 quickly imports the matching data into the detection storage chip medium 13 for data detection and matching. The test data status is then used to generate a report using the comparison report generator 14, which is then displayed on the screen 15 to determine whether it is the same as the original data. This generates a detailed test comparison report that clearly shows the differences between the tested software data and the standard data, allowing operators to quickly analyze and judge the data.
